第一步：新建一个maven project
第二步：发现跟标准的Maven project相比差点resources，所以点击项目按照如下流程新建src/main/resources和src/test/resources
第三步：往pom.xml添加相应的依赖
3.1 首先添加spring boot的相关依赖
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.0.5.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
<!-- https://mvnrepository.com/artifact/org.mybatis.spring.boot/mybatis-spring-boot-starter -->
<dependency>
<groupId>org.mybatis.spring.boot</groupId>
<artifactId>mybatis-spring-boot-starter</artifactId>
<version>1.3.1</version>
</dependency>
3.2 添加mybatis自动生成器的依赖
<!-- MyBatis 生成器 -->
<dependency>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-core</artifactId>
<version>1.3.5</version>
</dependency>
3.3 涉及跟数据表字段的操作，所以数据库相关也得添加依赖
<!-- https://mvnrepository.com/artifact/mysql/mysql-connector-java -->
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>${mysql.version}</version>
</dependency>
<!-- https://mvnrepository.com/artifact/com.alibaba/druid -->
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>druid</artifactId>
<version>1.1.12</version>
</dependency>
3.4 mybatis自动生成是以插件形式生成代码，所以需要再pom的build标签的plugins增加如下插件
3.4.1 springboot整合maven的插件
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
3.4.2 mybatis自动生成器插件
<plugin>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-maven-plugin</artifactId>
<version>1.3.5</version>
<configuration>
<verbose>true</verbose> <!-- 允许移动生成的文件 -->
<overwrite>false</overwrite> <!-- 允许覆盖文件 -->
<configurationFile> <!-- 自动生成代码的xml文件地址 -->
src/main/resources/generator/mybatis-generator.xml
</configurationFile>
</configuration>
</plugin>
第四步：配置自动生成文件的xml文件
<generatorConfiguration>
<!--Mysql包的绝对地址 -->
<classPathEntry location="D:\Maven\Repository\mysql\mysql-connector-java\5.1.41\mysql-connector-java-5.1.41.jar" />
<context id="mysqlDB" targetRuntime="MyBatis3">
<!-- 生成的pojo，将implements Serializable-->
<plugin type="org.mybatis.generator.plugins.SerializablePlugin"></plugin>
<commentGenerator>
<!-- 是否去除自动生成的注释 true：是 ： false:否 -->
<property name="suppressAllComments" value="true" />
</commentGenerator>
<jdbcConnection driverClass="com.mysql.jdbc.Driver"
connectionURL="jdbc:mysql://localhost:3306/test"
userId="root"
password="******"> <!--换成你自己数据库的密码 -->
</jdbcConnection>
<javaTypeResolver >
<property name="forceBigDecimals" value="false" />
</javaTypeResolver>
<javaModelGenerator targetPackage="com.cxj.springboot.domain" targetProject="src/main/java">
<property name="enableSubPackages" value="true" />
<!-- 从数据库返回的值被清理前后的空格 -->
<property name="trimStrings" value="true" />
</javaModelGenerator>
<sqlMapGenerator targetPackage="mapper" targetProject="src/main/resources">
<property name="enableSubPackages" value="true" />
</sqlMapGenerator>
<javaClientGenerator type="XMLMAPPER" targetPackage="com.cxj.springboot.mapper" targetProject="src/main/java">
<property name="enableSubPackages" value="true" />
</javaClientGenerator>
<!-- 映射数据库里面的表 -->
<table tableName="user_info" domainObjectName="UserInfo" mapperName="UserMapper" enableCountByExample = "false" enableUpdateByExample = "false" enableDeleteByExample ="false" enableSelectByExample="false" selectByExampleQueryId="false">
</table>
</context>
</generatorConfiguration>
第五步：使用eclipse的Run as命令里面的build，输入mybatis-generator:generate，代码生成完毕
