1,首先 单个的 springboot 工程会建

可以一直下一步

需要四个工程(左右)

2,如图 这四个就是我建的springboot工程

　　将parent_house 工程中的 src 文件夹删除

　　domain_house  和 service_house 工程的 src   里面的 java文件夹和resource 文件夹 里面的东西删掉

　　web_house 里面可以不用动

3,配置文件

　　parent 配置文件

  <parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.1.4.RELEASE</version><relativePath/> <!-- lookup parent from repository --></parent><groupId>com.house.demo</groupId><artifactId>parenter_house</artifactId><version>0.0.1-SNAPSHOT</version><name>parenter_house</name><packaging>pom</packaging><description>Demo project for Spring Boot</description><properties><java.version>1.8</java.version></properties><modules><module>../web_house</module><module>../domain_house</module><module>../service_house</module></modules><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency></dependencies><build><plugins><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-compiler-plugin</artifactId><version>3.1</version><configuration><source>${java.version}</source><target>${java.version}</target></configuration></plugin><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-surefire-plugin</artifactId><version>2.12.4</version><configuration><skipTests>true</skipTests>    <!--默认关掉单元测试 --></configuration></plugin></plugins></build>

　　domain  配置文件

<parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.1.4.RELEASE</version><relativePath/> <!-- lookup parent from repository --></parent><groupId>com.house.demo</groupId><artifactId>domain_house</artifactId><version>0.0.1-SNAPSHOT</version><name>domain_house</name><description>Demo project for Spring Boot</description><properties><java.version>1.8</java.version></properties><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency></dependencies><build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId></plugin></plugins></build>

　　service 配置文件

  <parent><groupId>com.house.demo</groupId><artifactId>parenter_house</artifactId><version>0.0.1-SNAPSHOT</version><relativePath>pom.xml</relativePath></parent><groupId>com.house.demo</groupId><artifactId>service_house</artifactId><version>0.0.1-SNAPSHOT</version><name>service_house</name><packaging>jar</packaging><description>Demo project for Spring Boot</description><properties><java.version>1.8</java.version></properties><dependencies><dependency><groupId>com.house.demo</groupId><artifactId>domain_house</artifactId><version>0.0.1-SNAPSHOT</version></dependency><dependency><groupId>org.mybatis.spring.boot</groupId><artifactId>mybatis-spring-boot-starter</artifactId><version>2.0.1</version></dependency><dependency><groupId>org.apache.tomcat.embed</groupId><artifactId>tomcat-embed-core</artifactId></dependency></dependencies>

　　web配置文件

  <parent><groupId>com.house.demo</groupId><artifactId>parenter_house</artifactId><version>0.0.1-SNAPSHOT</version><relativePath>pom.xml</relativePath></parent><groupId>com.house.demo</groupId><artifactId>web_house</artifactId><version>0.0.1-SNAPSHOT</version><packaging>jar</packaging><name>web_house</name><description>Demo project for Spring Boot</description><properties><java.version>1.8</java.version></properties><dependencies><dependency><groupId>com.house.demo</groupId><artifactId>service_house</artifactId><version>0.0.1-SNAPSHOT</version></dependency><dependency><groupId>com.house.demo</groupId><artifactId>domain_house</artifactId><version>0.0.1-SNAPSHOT</version></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId></dependency></dependencies><!--spring boot打包的话需要指定一个唯一的入门--><build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId><configuration><!-- 指定该Main Class为全局的唯一入口 --><mainClass>com.example.WebApplication</mainClass><layout>ZIP</layout></configuration><executions><execution><goals><goal>repackage</goal><!--可以把依赖的包都打包到生成的Jar包中--></goals></execution></executions></plugin></plugins></build>

虽然都是springboot 工程  pom  文件中 配置父子关系,及依赖关系

还需要自己去调包结构

===下面是我自己工程的代码===================================================================================================================

目录:

实体类请和自己的表的字段对应

mapper 和service

resource文件夹里面是

web工程的目录和代码( 请关注  usercontroller  和application 的内容 其他内容 忽略  properties 文件中有一部分是freemark的配置可以忽略  )
