Maven builds spring boot multi-module project

Maven builds spring boot multi-module project

Note: All projects are created in idea

1.idea Creating a Maven project

• 1-1: Delete src , target directory, keep onlypom.xml

• 1-2: The root directory pom.xml can be inherited by the module, so the project is only demo, not considering too many performance issues, so many dependent

  都写在根级`pom.xml`，子模块只需继承就可以使用。

• 1-3: root-level pom.xml files in Appendix 1

• 1-4: Dependent module MyBatis spring-boot related modules

2. Creating a submodule (module)

• 2-1: file > new > module Inputmodel

• 2-2: file > new > module Inputdao

• 2-3: file > new > module Inputservice

• 2-4: file > new > module Inputwebapi

3. Modify sub-module Pom.xml configuration

<?xml version="1.0" encoding="UTF-8"?><Projectxmlns="http://maven.apache.org/POM/4.0.0"Xmlns:xsi="Http://www.w3.org/2001/XMLSchema-instance"xsi:schemalocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" ><Parent><Artifactid>parent</Artifactid><groupid>com.luyh.projectv1</groupid> <version>1.0-snapshot</  Version> <relativepath> ... /pom.xml</relativepath> </parent> <modelversion>4.0.0</ modelversion> <artifactid>projectv1-model</artifactid></  project>                 

Note: <font color= "Red" > <relativePath>../pom.xml</relativePath> </font> This segment must be added to inherit the parent module

At this point, the infrastructure of the project has been built, the next can be the code, OH oh wait, I first introduce the sub-module of the job responsibilities it

4. Sub-modules ' job responsibilities ' in the project

• modelThis module holds all the entity classes

• daoThis module holds the specific implementation of data interaction for service invocation

• serviceThis module holds the business code implementation for the API layer to invoke

• webapiThis module can also not appear in the project, in order to write the demo so the WEBAPI layer is put in

5. modelLayer entity class writing

• Create Package Namecom.luyh.projectv1.model

• Build entity class Member.java specific code please clone my git,git address at the bottom

6. daoLayer Database Operations Layer

• Build Com.luyh.projectv1.dao.config with only 2 configuration Java classes in the package that let spring boot automatically load the configuration

• Build Membermapper.java specific content to see the code

• Build Membermapper.xml under the Resources/mybatis

• Establish Imember.java

• Establishing Member.java to implement Imember interface

• Establishing a resources/application.properties file for configuring database connections

7. serviceWriting business logic

• Create a com.luyh.projectv1.service Package

• Establishing the Imemberservice.java interface

• Establishing the Memberservice.java implementation class

• The Memberservice.java class automatically injects Daomember and calls its methods to get the data

8. webapiWrite WEBAPI get JSON data

• Establish Application.java Launch application

• Create com.luyh.projectv1.webapi.controller.MemberController.java a REST style controller

• Start

9.sql file Please import MySQL data sql file yourself
