1、在idea的插件中心中安装最新版的mybatis-plugin,安装完成后退出idea
2、找到idea中mybatis-plugin的安装路径,在mac中,一般为
open ~/Library/Application Support/IntelliJIdea2016.3/mybatis_plus/lib
3、下载替换文件
http://www.awei.org/download/iMybatis-3.21.jar
或者替换lib文件
https://gitee.com/loubobooo/mybatis_plugin/repository/archive/master.zip
4、替换后重启IDE
5、使用Mybatis-plugin
(1 )在maven项目的pom.xml 添加mybatis-generator-maven-plugin 插件和MySQL数据库驱动依赖)
<build>
<plugins>
<plugin>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-maven-plugin</artifactId>
<version>1.3.5</version>
<configuration>
<verbose>true</verbose>
<overwrite>true</overwrite>
</configuration>
</plugin>
</plugins>
</build>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.34</version>
</dependency>
(2)在maven项目下的src/main/resources 目录下建立名为 generatorConfig.xml的配置文件,作为mybatis-generator-maven-plugin 插件的执行目标,模板如下:
<?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">
<generatorConfiguration>
<!-- 配置mysql 驱动jar包路径.用了绝对路径 -->
<classPathEntry location="/Users/wangyongzhi/.m2/repository/mysql/mysql-connector-java/5.1.34/mysql-connector-java-5.1.34.jar" />
<context id="wangyongzhi_mysql_tables" targetRuntime="MyBatis3">
<!-- 防止生成的代码中有很多注释,加入下面的配置控制 -->
<commentGenerator>
<property name="suppressAllComments" value="true" />
<property name="suppressDate" value="true" />
</commentGenerator>
<!-- 数据库连接 -->
<jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://127.0.0.1:3306/test?useUnicode=true&characterEncoding=UTF-8" userId="root" password="123456">
</jdbcConnection>
<javaTypeResolver >
<property name="forceBigDecimals" value="false" />
</javaTypeResolver>
<!-- 数据表对应的model层 -->
<javaModelGenerator targetPackage="me.zhige.domain" targetProject="src">
<property name="enableSubPackages" value="true" />
<property name="trimStrings" value="true" />
</javaModelGenerator>
<!-- sql mapper 映射配置文件 -->
<sqlMapGenerator targetPackage="me.zhige.mapper" targetProject="src">
<property name="enableSubPackages" value="true" />
</sqlMapGenerator>
<!-- mybatis3中的mapper接口 -->
<javaClientGenerator type="XMLMAPPER" targetPackage="me.zhige.dao" targetProject="src">
<property name="enableSubPackages" value="true" />
</javaClientGenerator>
<!-- 数据表进行生成操作 schema:相当于库名; tableName:表名; domainObjectName:对应的DO -->
<table schema="test" tableName="users" domainObjectName="User" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false">
</table>
</context>
</generatorConfiguration>
(3)使用maven运行mybatis-generator-maven-plugin插件:工程名->Plugins->mybatis-generator->mybatis-generator:generate->Run Maven Build
