Before finishing the new version of the three major SSM framework, this article is about its integration process and project source code, the version numbers are: Spring 5.2.2.RELEASE, SpringMVC 5.2.2.RELEASE, MyBatis 3.5.2.
Background introduction
ssm-demo is the first open source project I posted on GitHub. The project should be developed at the end of 2016, and then I chose to open source this project to the GitHub open source platform.
It was a relatively common phenomenon to use Spring 4.X version when developing Java Web projects at that time in 2016, and it does not make people feel that the version is behind, but it is already 2020, so Spring was carried out on the basis of the original code. Relevant framework upgrades, so I organized the integration of the three major SSM framework tutorials related to this Spring 5 version.
Spring 5 is here
Spring 5 is a very important version update. You can also see that this version is updated frequently in its open source warehouse. Everyone should believe that this version will gradually take up an increasing share in enterprise development.
Briefly talk about the version number selected in this tutorial:
-
The Spring version chose a relatively new version, which was upgraded from the original 4.2.4.RELEASE to 5.2.2.RELEASE. This version was officially released on October 3, 2019, and the version update log was v5.2.2.RELEASE .
-
The version of Spring MVC is also updated with the version of Spring, which is also 5.2.2.RELEASE.
-
The version of MyBatis is upgraded to 3.5.2, MyBatis 3.5 and above corresponds to Spring 5 and above, Spring 4 does not support MyBatis 3.5 and above, the corresponding version of mybatis-spring also needs to be upgraded to version 2.0 and above, I chose to 2.0.1.
The above is the version selection of the three major SSM frameworks. The version number is selected and integrated by myself. You can fine-tune it, but you must pay attention to the test and do not report errors.
Main code integration
The directory structure of the source code is as follows:
pom dependency
The main version numbers of the three major frameworks of Spring Spring MVC MyBatis have been introduced, here I directly give the pom.xml file:

复制代码Enable Controller package scanning and view parser configuration.
MyBatis configuration
The configuration file of mybatis-config.xml is as follows:
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration

"http://mybatis.org/dtd/mybatis-3-config.dtd">

</typeAliases>
</configuration>
复制代码web.xml configuration
Finally, the most important configuration file in the Java Web project: web.xml. Here we will load the relevant configuration of Spring and start the Spring container. At the same time, we will configure SpringMVC and hand over all requests to the front controller DispatcherServlet for processing.
The web.xml configuration file is as follows:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee"

复制代码JSP page
Finally, there is a JSP page for testing. Create a new index.jsp in the webapp directory. The code is as follows:
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>ssm demo</title>
</head>
<body>
Hello SSM ( Spring 5.2 + MyBatis 3.5)!
</body>
</html>
复制代码Project launch and preview
I have tested the source code. After deploying to Tomcat and starting it, you can see the following page:
The integration of the three major SSM frameworks of Spring 5 is successful!
This is an integration tutorial for Spring 5 + Spring MVC 5 + MyBatis 3.5. It is just for integration. It is for everyone to refer to when upgrading Spring 5. Other functions can be implemented by themselves. It can also be expanded with the open source project I wrote before.
Precautions
- Request suffix
What is set here is to intercept the request at the end of .do, you can modify it according to your needs.
- Mapper file
Since there is no Mapper file added to the project, I commented out this line of configuration. After you add the Mapper file, you need to remove this line of comment.
Source code download
The download link is as follows:
download.csdn.net/download/ZH…
During the upload, I set that I do n’t need to download points. If I need to download points later, it should be set by the CSDN platform.
Write at the end
As a small promotion, interested friends can take a look. Recently, I published a small booklet "Spring Boot Large-scale Online Mall Project Practical Tutorial" on the Nuggets platform (click the link or click the picture below to purchase to get a discount 8 Fold ):
The booklet will focus on the Spring Boot technology stack, and other technical frameworks used will also take into account the latest technology trends and expand knowledge, from shallow to deep, step by step, while learning the basics, you can also master certain development skills, not just learning Spring. Boot's fur is also aware of its source code design and internal principles. It not only learns the integration of Spring Boot's related technology stacks, but also can use the Spring Boot technology stack to build a large shopping mall system, so that you have a high-quality learning progress. Level experience. Staying away from the Hello World project, you can not only get a complete hands-on project, but also help you fill the current hot Spring Boot technology stack, providing sufficient protection for your technical depth and salary promotion.
This is a practical project of a shopping mall. Some page previews are as follows:
Interested friends can look at.
