SpringBoot2多模块项目集成mybatis-plus

本人使用的springboot版本为2.1.7，先引入依赖

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <scope>runtime</scope>
</dependency>
<dependency>
    <groupId>com.baomidou</groupId>
    <artifactId>mybatis-plus-boot-starter</artifactId>
</dependency>
<!-- mybatis plus 代码生成器依赖 -->
<dependency>
    <groupId>com.baomidou</groupId>
    <artifactId>mybatis-plus-generator</artifactId>
</dependency>

版本在父模块统一管理

<mysql-connetor-java.version>8.0.17</mysql-connetor-java.version>
<mybatis-plus-boot-starter.version>3.3.0</mybatis-plus-boot-starter.version>

<dependencyManagement>

<dependency>
   <groupId>mysql</groupId>
   <artifactId>mysql-connector-java</artifactId>
   <version>${mysql-connetor-java.version}</version>
   <scope>runtime</scope>
</dependency>

<!--mybatis plus start-->
<dependency>
   <groupId>com.baomidou</groupId>
   <artifactId>mybatis-plus-boot-starter</artifactId>
   <version>${mybatis-plus-boot-starter.version}</version>
</dependency>
<dependency>
   <groupId>com.baomidou</groupId>
   <artifactId>mybatis-plus-generator</artifactId>
   <version>${mybatis-plus-boot-starter.version}</version>
</dependency>

//其余略

</dependencyManagement>

在这里多嘴一句，用了mybatis-plus，就要把mybatis的相关依赖都去掉，避免冲突，包括pageHelper也不要用springboot的

如下，去掉依赖：

<!--mybatis -->
<dependency>
   <groupId>org.mybatis.spring.boot</groupId>
   <artifactId>mybatis-spring-boot-starter</artifactId>
   <version>${mybatis-spring-boot-starter.version}</version>
</dependency>

<dependency>
   <groupId>com.github.pagehelper</groupId>
   <artifactId>pagehelper-spring-boot-starter</artifactId>
   <version>${pagehelper-spring-boot-starter.version}</version>
</dependency>

pageHelper依赖换为：

<!--pageHelper 处理分页 -->
<dependency>
   <groupId>com.github.pagehelper</groupId>
   <artifactId>pagehelper</artifactId>
   <version>4.0.0</version>
</dependency>

或者将mybatis相关的依赖包排除掉：

<dependency>
   <groupId>com.github.pagehelper</groupId>
   <artifactId>pagehelper-spring-boot-starter</artifactId>
   <version>1.2.3</version>
   <exclusions>
      <exclusion>
         <groupId>org.mybatis</groupId>
         <artifactId>mybatis</artifactId>
      </exclusion>
      <exclusion>
         <groupId>org.mybatis</groupId>
         <artifactId>mybatis-spring</artifactId>
      </exclusion>
   </exclusions>
</dependency>

目前我是这样处理得，如果你们有更好的解决方法，欢迎提出来。

application.yml配置驼峰和简写

mybatis-plus:
  configuration:
    map-underscore-to-camel-case: true
  type-aliases-package: com.xxxx.xxx.base.entity

分页配置也很重要，别忘记了，不然分页是不生效的

@Configuration
public class MybatisPlusConfig {
    /**
     * 分页插件
     */
    &
