maven插件mybatis-generator生成代码

第一步，在pom中加入插件

 <plugin>
     <groupId>org.mybatis.generator</groupId>
     <artifactId>mybatis-generator-maven-plugin</artifactId>
     <version>1.3.2</version>
     <configuration>
         <configurationFile>src/main/resources/generatorConfig.xml</configurationFile>
         <verbose>true</verbose>
         <overwrite>true</overwrite>
     </configuration>
     <executions>
         <execution>
             <id>Generate MyBatis Artifacts</id>
             <goals>
                 <goal>generate</goal>
             </goals>
         </execution>
     </executions>
     <dependencies>
         <dependency>
             <groupId>mysql</groupId>
             <artifactId>mysql-connector-java</artifactId>
             <version>5.1.46</version>
         </dependency>
         <dependency>
             <groupId>org.mybatis.generator</groupId>
             <artifactId>mybatis-generator-core</artifactId>
             <version>1.3.2</version>
         </dependency>
     </dependencies>
 </plugin>

第二步，在resource中添加文件：generatorConfig.xml

 <?xml version="1.0" encoding="UTF-8"?>
 <!DOCTYPE generatorConfiguration
         PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
         "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">

 <!-- 配置Run As Maven build : Goals 参数 : mybatis-generator:generate -Dmybatis.generator.overwrite=true -->
 <!-- 配置 tableName,使用 Run As Maven build 生成 dao model 层 -->
 <generatorConfiguration>
     <!-- 配置文件路径
     <properties url="${mybatis.generator.generatorConfig.properties}"/>-->

     <!--数据库驱动包路径 -->
     <classPathEntry location="/Users/weianlai/mysql-connector-java-5.1.21.jar"/>

     <context id="DB2Tables" targetRuntime="MyBatis3">
         <!--关闭注释 -->
         <commentGenerator>
             <property name="suppressAllComments" value="true"/>
         </commentGenerator>

         <!--数据库连接信息 -->
         <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://localhost:3306/demo" userId="root"
                         password="root">
         </jdbcConnection>

         <!--生成的model 包路径 -->
         <javaModelGenerator targetPackage="com.example.demo.common.entity" targetProject="src/main/java">
             <property name="enableSubPackages" value="ture"/>
             <property name="trimStrings" value="true"/>
         </javaModelGenerator>

         <!--生成xml mapper文件 路径 -->
         <sqlMapGenerator targetPackage="mybatis.mapper" targetProject="src/main/resources">
             <property name="enableSubPackages" value="ture"/>
         </sqlMapGenerator>

         <!-- 生成的Dao接口 的包路径 -->
         <javaClientGenerator type="XMLMAPPER" targetPackage="com.example.demo.dao.mapper" targetProject="src/main/java">
             <property name="enableSubPackages" value="ture"/>
         </javaClientGenerator>

         <!--对应数据库表名，多个表，请复制指定 -->
         <!--<table tableName="user"></table>-->
         <table tableName="user" domainObjectName="User" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false" />
         <!--<table tableName="T_ROLE"></table>-->
         <!--<table tableName="T_USER_ROLE"></table>-->
         <!--<table tableName="T_PERMISSION"></table>-->
     </context>
 </generatorConfiguration>

第三步，双击插件
