Abstract: With the development of economic globalization, the contact between international trade is getting closer and

closer, which has a profound impact on China's economy and trade. With the update of Internet technology,

the disadvantages of traditional trade communication are becoming more and more obvious, and the market

demands more and more strict economic talents in colleges and universities. Therefore, this paper constructs

an applied international trade simulation training system under the background of "internet plus" education.

This system uses IDEA as the development and compilation tool when developing JavaWeb applications, and

JDK 1.8 as the development environment, CSS3+HTML5+Javascript as the front-end development language,

and Java as the back-end development language. The overall design scheme of the system will be deployed

in layers according to MVC mode, which will support users to make better use of the training function in the

system and ensure the training effect. On the system framework, vue.js is used at the front end, SSH

framework of spring+springmvc+hibernate is used at the back end, and MySQL is used as the relational

database of the system to store massive trade data. It can ensure the integrity of information resources of the

simulation training system and help the further development of intelligent teaching of international trade

major in colleges and universities.

1 INTRODUCTION

Report to the 20th CPC National Congress pointed

out: "High-quality development is the primary task of

building a socialist modern country in an all-round

way, and high-level opening is the inherent

requirement of achieving high-quality development".

(He, 2016) The further development of economic

globalization has become the current mainstream

trend, and the contact between countries has become

more frequent. International trade is the main means

to promote the economic development of all

countries. It can adjust the world economic structure

by adjusting the utilization rate of domestic

production factors, improve the supply and demand

relationship among countries, and finally accomplish

the fundamental task of increasing fiscal revenue.

With the change of economic structure, the

requirements of the society for practical trade talents

are becoming more and more strict. As the main

position of cultivating talents, colleges and

universities should keep up with the trend of social

changes, and change the talent training mode with the

help of digital electronic technology, so as to cultivate

applied international trade talents with ability and

political integrity to meet the social needs and

promote the development of the country. But at

present, there are still the following problems in the

cultivation of international trade professionals in

colleges and universities. First of all, the teaching

mode in colleges and universities is single. Most

colleges and universities still use the traditional

theoretical teaching mode, ignoring the importance of

practice, which leads to the lack of practical

experience of most college students and makes it

difficult for them to integrate into social work.

Secondly, the content of practical training is outdated,

lacking in new ideas, and out of touch with the

development needs of social reality. Most of the

training contents in colleges and universities are the

same, and they are not updated for a long time, which

reduces the interest of college students in learning and

makes the training lose its own meaning. Finally, in

recent years, under the situation of epidemic diseases,

colleges and universities are unable to organize

students to carry out offline enterprise training

activities, which leads to students' lack of training

experience and aggravates the difficulty of

employment. All the above problems need to be

solved urgently.

In view of a series of problems existing in the

process of training international trade talents in

colleges and universities, colleges and universities

should timely reform the current training mode and

change training strategies. On the premise of

scientific and technological development, they should

reform the outdated teaching mode and enrich the

teaching contents of international trade majors, so as

to improve the professional skills and practical skills

of college students and make them become high-

quality applied international trade talents. Based on

the development advantages of digital electronic

technology, this paper constructs an applied

international trade simulation training system under

the background of "internet plus". By making full use

of Internet technology, a learning environment for all-

round training from learning to using is constructed,

and the current situation of insufficient practical

education is improved, so that the educational content

of international trade in colleges and universities is

more in line with the actual needs of the society. At

the same time, the information-based training system

can better meet students' study habits, thus improving

the teaching effectiveness of international trade

training.

2 KEY TECHNOLOGY

2.1 SSH

SSH is an integrated framework composed of

struts+spring+hibernate, which is usually used for the

overall framework development of web applications,

and has the characteristics of open source and free.

SSH framework can be divided into four layers

according to responsibilities, namely, presentation

layer, business logic layer, data persistence layer and

domain module layer. This detailed structure mode

according to responsibilities can make users build

web applications more efficiently. (Ji, 2008) In SSH

framework, Struts is the basic structure of the system,

which is mainly responsible for controlling the jump

of system business and the separation of MVC.

Spring's control inversion can play the role of

decoupling, so that Struts and Hibernate can work

together better and coordinate, and its management

ability runs through the whole system. Hibernate

itself is a relational mapping framework with open

source code, which can automatically generate and

execute data statements. SSH, as the most classic

three-tier architecture, perfectly deploys the system

structure in layers, thus improving the operation

efficiency. Users can make use of its excellent

extensibility to carry out secondary development,

thus creating functions that are more suitable for

individual needs and reducing the time cost of system

development. (Pan, 2019) Its specific operation

process is shown in Figure 1.

2.2 Java

Java is a simple programming language. Its syntax is

similar to that of C language, but it is different. The

general difference is shown in Table 1. It doesn't take

users too long to finish learning and writing. The

reference of Java language increases the utilization

rate of the system memory space, and the system will

automatically allocate and recycle the memory space

on a regular basis, so as to avoid the situation of

memory over-fullness. It also has the advantage of

object-oriented. Java language not only supports

single inheritance between classes but also supports

multiple inheritance between interfaces, thus

achieving the implementation mechanism between

classes and interfaces. The biggest function of Java is

to make web pages lively. Java has a wide range of

APPlications, including Android mobile app, large

websites and PC software.

2.3 MySQL

MySQL is not only a database management system,

but also a relational database. Because of its open

source characteristics, users can rewrite the source

code of the database according to their own needs, so

as to build a new system. Because of its own

characteristics, MySQL can run on all kinds of system

platforms and support all operating systems, among

which the most common ones are Unix, Linux and

Windows. At the same time, MySQL is also an

important part of LAMP stack. Applying MySQL's

unique performance advantages to web program

development can greatly improve the development

efficiency of staff. Its working mode adopts C/S

structure, and the running tasks in the system are

undertaken by the client and the server respectively,

which improves the running efficiency and the

utilization rate of system resources. Most of the data

resources in MySQL are managed centrally, which

ensures the safe storage of system data while making

efficient use of resources, so it becomes one of the

most popular databases at present. (Teng, 2022)

2.4 Development Process

According to the system development requirements

and the use requirements of the above key

technologies, complete the configuration and

deployment of the development environment. The

overall development of the system is based on

Windows10.0 operating system, and Java is selected

as the basic language of the system development.

JDK1.8 is selected as the development kit, Tomcat8.0

is selected as the Web server for the system

development, Eclipse is selected as the Java

integrated development tool, and MySQL database is

selected for data storage. After downloading,

installing and configuring the above software systems

one by one, the development environment of the

system is built. Create a new Web project under

Eclipse system and name it SSH. Click Finish to pop

up a dialogue window. After the completion of the

new project, the homepage of index.jsp will be

automatically generated in the root directory of the

website, and then double-click it to change This is my

JSP page. to the homepage, and then use Ctrl+S to

save it. Then, on the top menu bar, click My Eclipse

under Preferences in the window, modify the coding

in JSP and click OK to apply the unified coding

format. Then build Struts framework: introduce

Struts-2.3.30-apps resource package, create an action

class, and correspondingly create dao class and

service class in the middle. Hibernate framework

construction: you need to install the Hibernate Tools

plug-in, introduce the Hibernate-release-5.2.2. Final

resource package, and connect to the SQLserver

database. Construction of Spring Framework:

Introduce the Spring-framework-4.2.2. RELEASE

resource package and configure the web.xml file.

Then, the three frameworks are integrated, the Action

class of Struts is managed by Spring, and the Session

of hibernate is managed and deployed by Spring.

After the above steps are completed, conduct

simulation test. After the test is correct, package the

whole system and put it into Tomcat server. After

Construction of Applied International Trade Simulation Training System Under the Background of "Internet Plus"

setting the IP address, it can be used normally.

Through the introduction of the above key

technologies and theories, the overall framework

process of the development of international trade

simulation training system is determined, and the

feasibility of the establishment and operation of the

system is clarified.

3 FUNCTIONAL

IMPLEMENTATION

3.1 Student Side

3.1.1 Basic Practical Training Module

International trade major is a comprehensive major,

and its teaching content covers all disciplines, so it is

difficult to understand. Therefore, this module is

designed to enable students to master the basic

knowledge of international trade and build rational

economic thinking for college students through a

series of basic practical training. Users who use this

system for the first time need to register. After

completing the user registration according to the

relevant prompts of the system, they can log in. The

divided into four parts: foreign exchange transaction

simulation training, document training, international

settlement simulation training and international

freight forwarding simulation training. In the foreign

exchange transaction simulation training, students

mainly take foreign exchange trading as the main

learning object. After knowing some basic theoretical

knowledge, they can use the trading function of the

system to simulate foreign exchange trading,

understand and learn the trading forms of foreign

exchange market, the calculation method and

quotation form of foreign exchange rate. During the

simulation, the system will regularly push the real-

time information and risk warning of the foreign

exchange market, giving students the truest operating

experience. In the document training module,

students can simulate the real import and export

documents through the system's document making

function, so as to master the basic principles and

general contents of document making, so that

students can gain practical skills and meet the talent

needs of the society. (Ji, 2008) In the international

settlement simulation training, the system will

generate documents and bills of international

settlement according to users' needs, so that students

can learn systematically. At the end of the study, users

can click the bill simulation function under the

module to simulate the production of bills, so as to

have a deeper understanding of the international bill

production methods and the main business processes

of international settlement, and improve the

settlement ability. In the international freight

forwarding simulation training, the system will

provide students with a real international business

communication environment. Students can work out

the details of international trade, such as exchanged

goods and driving routes, so as to enrich their trade

thinking and cultivate their decision-making ability.

Through the study of this module, college students

can master the solid basic theory of international trade

and lay the foundation for the follow-up study.

Figure 2: System accession code.

3.1.2 Comprehensive Practical Training

Module

In this module, the system focuses on comprehensive

training as the main teaching object, aiming at

cultivating students' professional ability and

improving students' comprehensive quality through

comprehensive training education. In order to enable

students to integrate their knowledge and form a

complete knowledge framework, this module

systematically simulates international trade in more

detail. Students can participate in the whole process

of international trade exchange with the help of the

comprehensive training function of the system. Click

the comprehensive training module system to

automatically generate a trading company, and then

the subsequent corresponding operations can be

started. Students need to independently work out the

company's trade development strategy, find interested

cooperative companies, then conduct trade

consultation, sign contracts and a series of trade

ICEMME 2022 - The International Conference on Economic Management and Model Engineering

communication issues. (Bao, 2022) The system will

also provide a simulated international trade exchange

platform, which contains a large number of supply

and demand messages and basic data, and users'

companies can conduct trade interaction on this

platform. The code of user interaction is shown in

Figure 3. Through comprehensive training, students

can master the basic trade operation skills such as

import and export cost accounting, inquiry, offer,

counter-offer and so on in a short time, have some

knowledge of the logistics, capital flow and business

flow of international trade, and quickly understand

the overall operation of foreign trade practice, so that

students can consolidate their knowledge in practice

and further improve their problem-solving ability.

Figure 3: User interaction section code.

3.1.3 Career Experience Module

Under this module, students can choose positions in

international trade exchanges according to their

personal interests, such as foreign trade

merchandiser, international freight forwarder,

business voucher clerk, customs broker and customs

inspector. These positions are subject to the rotation

system, and students need to change positions

regularly to ensure that students can fully experience

each position in the trade link. Through this kind of

personal experience, students can better learn trade

skills, be familiar with the overall process and

business operation mode of international trade

exchanges. Thus enhancing their working skills,

enabling college students to quickly integrate into

social work after graduation, and promoting China's

economic development.

3.2 Teacher Side

In this system, the functions of teachers are more

inclined to organize, guide and supervise learning

activities. Teachers can assign simulated roles to

students who participate in internships, and can also

arbitrate disputes in simulated trade. With the help of

the tracking function of the system, students'

operation can be monitored in real time, so as to avoid

the situation of brushing learning time. Teachers can

also make adjustments to commodity prices and

costs, foreign currency exchange rates, insurance

payout ratio and other trade costs by publishing real-

time information in announcements, and preset the

probability of accidental events to enhance the

authenticity of simulation training, which enables

students to give full play to their subjective initiative

in the training process, cultivate students' ability to

cope with risks, and promote students' growth. The

scoring standard of training consists of two parts:

process evaluation and outcome evaluation. Teachers

will give subjective scores according to the final

training results, which can be divided into three

grades: excellent, good and average, corresponding to

five, three and one weights respectively. At the end of

the evaluation, the system will automatically

construct the evaluation model matrix, combine all

teachers' scores with the system's automatic scores,

and introduce confidence A to complete the final

score evaluation. The calculation formula of students'

comprehensive score M is shown in Formula 1, in

which K represents academic completion, Q

represents automatic grading of training operating

system, P represents teacher evaluation, and G

represents students' test scores.

4 CONCLUSIONS

With the development of economy, the trade between

countries becomes more and more frequent. The

traditional teaching mode of international trade can't

meet the needs of students and society, so this paper

constructs an applied international trade simulation

training system based on the "internet plus" education

background. The establishment of this system breaks

the traditional trade teaching mode, enriches the

practical ways of international trade, enables students

to study deeply in the real international trade

exchange scene, enhances students' operational and

practical abilities, and lays the foundation for

cultivating applied international trade talents. In the

follow-up research, this platform will continue to

expand the depth and practicality of the system, and

promote the further improvement of the system

functions.
