Project Description

The project is based on a B/S architecture system and adopts Java object-oriented programming ideas. Mainly relying on SpringBoot, Vue, WeChat applet development and other technologies, system users are divided into two categories: administrators and customers, who log in to the system through computer browsers and mobile phone WeChat applets respectively.

Java project construction (IDEA)

1. Create a new project

2.Project type

3.Project settings

• Group: The Group ID of the project, usually the reverse of the company domain name, such as com.example.
• Artifact: Artifact ID of the project, which is the project name.
• Type: Select "Maven" or "Gradle" as the build tool.
• Language: Select "Java".
• Packaging: Select "Jar".
• Java Version: Select the Java version you wish to use.
• Version: Select the Spring Boot version.

The installed IDEA version only supports Java versions 17 and 21. Select first and then change the pom.xml file.

• Dependencies: Select the dependencies you need, such as "Spring Web" for building web applications.

4. Project storage location and project name

5. Install the Lombok plug-in in idea

In idea: file——>settings——>plugins (plug-in)

6.Project structure

The standard directory structure of Spring Boot is as follows:

my-spring-boot-project/
├── src/
│   ├── main/
│   │   ├── java/                   # Java 源代码目录
│   │   │   └── com/

Among them,src/main directory contains the main Java code and resource files. src/test The directory contains test case code and resource files.

In thesrc/main/java directory, it usually contains the MySpringBootApplication class that starts the application and other related business logic codes, including controllers, services, entities, etc. .

In the src/main/resources directory, it usually contains the configuration file of the application, such as application.properties or application.yml. In addition, some static resource files (such as HTML, CSS and JavaScript files) and template files (such as Thymeleaf templates) can also be stored here.

In the src/test/java directory, it usually contains the test case code for the application. These test classes are usually in the same package as the class being tested, and have names ending in xxxTests.java.

In the src/test/resources directory, it usually contains the resource files required for test cases.

pom.xmlIt is the configuration file of the Maven project, including project dependencies, plug-ins and other information.

The above is just the standard directory structure of Spring Boot, you can modify or extend it according to actual needs.

7. Modify the Maven project configuration file pom.xml
