1、准备

mysql-connector-java-5.1.25-bin.jar

2、idea安装插件

点击 file->settings->plugins

搜索mybatis generator 安装重启

修改pom.xml

<build>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-maven-plugin</artifactId>

</plugin>

<groupId>org.mybatis.generator</groupId>

<artifactId>mybatis-generator-maven-plugin</artifactId>

<configurationFile>$\{basedir\}/src/main/resources/generator/generatorConfig.xml</configurationFile>

</configuration>

</plugin>

</plugins>

</build>

3、创建表

CREATE TABLE t\_user\_test(

user\_id INT NOT NULL PRIMARY KEY AUTO\_INCREMENT,

user\_name VARCHAR(255) NOT NULL ,

password VARCHAR(255) NOT NULL ,

phone VARCHAR(255) NOT NULL

) ENGINE=INNODB AUTO\_INCREMENT=1000 DEFAULT CHARSET=utf8;

4、配置文件

在resources下创建generator->generatorConfig.xml

内容如下：

<?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>  
  
<classPathEntry location="F:\\mybatis-generator-core-1.3.6\\lib\\mysql-connector-java-5.1.25-bin.jar"/>  
<context id="DB2Tables" targetRuntime="MyBatis3">  
<commentGenerator>  
<property name="suppressDate" value="true"/>  
  
<property name="suppressAllComments" value="true"/>  
</commentGenerator>  
  
<jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://127.0.0.1:3306/starsine\_dev" userId="root" password="123456">  
</jdbcConnection>  
<javaTypeResolver>  
<property name="forceBigDecimals" value="false"/>  
</javaTypeResolver>  
  
<javaModelGenerator targetPackage="com.example.fastdfs.entity" targetProject="src/main/java">  
<property name="enableSubPackages" value="true"/>  
<property name="trimStrings" value="true"/>  
</javaModelGenerator>  
  
<sqlMapGenerator targetPackage="mapping" targetProject="src/main/resources">  
<property name="enableSubPackages" value="true"/>  
</sqlMapGenerator>  
  
<javaClientGenerator type="XMLMAPPER" targetPackage="com.example.fastdfs.mapper" targetProject="src/main/java">  
<property name="enableSubPackages" value="true"/>  
</javaClientGenerator>  
  
<table tableName="t\_user\_test" domainObjectName="User" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>  
</context>  
</generatorConfiguration>  
5、配置启动文件
