1、mybatis-generator 生成DAO、Mapper、entity
所需环境:jdk
所需jar包:mybatis-generator-core-1.3.5.jar、MySQL-connector-java-5.1.34.jar
一:新建一个文件夹generator(这里我是在E盘新建的E:\generator)用来存放工具jar包和配置文件
二:将准备好的两个jar包直接放在generator文件夹下面
三:在新建的文件夹下面新建一个文件,命名:generator.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"> <generatorConfiguration> <!-- 数据库驱动包位置 --> <classPathEntry location="E:\generator\mysql-connector-java-5.1.34.jar" /> <!-- <classPathEntry location="C:\oracle\product\10.2.0\db_1\jdbc\lib\ojdbc14.jar" />--> <context id="DB2Tables" targetRuntime="MyBatis3"> <commentGenerator> <property name="suppressAllComments" value="true" /> </commentGenerator> <!-- 数据库链接URL、用户名、密码 --> <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://localhost:3306/bruce_test?characterEncoding=utf8" userId="root" password="123456"> </jdbcConnection> <javaTypeResolver> <property name="forceBigDecimals" value="false" /> </javaTypeResolver> <!-- 生成模型的包名和位置 --> <javaModelGenerator targetPackage="andy.model" targetProject="E:\generator\src"> <property name="enableSubPackages" value="true" /> <property name="trimStrings" value="true" /> </javaModelGenerator> <!-- 生成的映射文件包名和位置 --> <sqlMapGenerator targetPackage="andy.mapping" targetProject="E:\generator\src"> <property name="enableSubPackages" value="true" /> </sqlMapGenerator> <!-- 生成DAO的包名和位置 --> <javaClientGenerator type="XMLMAPPER" targetPackage="andy.dao" targetProject="E:\generator\src"> <property name="enableSubPackages" value="true" /> </javaClientGenerator> <!-- 多个表直接复制下面的,更改tableName和domainObjectName就可以--> <table tableName="bruce_userinfor" domainObjectName="Userinfor" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false" /> </context> </generatorConfiguration>
四 :打开cmd命令提示符,进入到E:\generator,输入命令:java -jar mybatis-generator-core-1.3.5.jar -configfile generator.xml -overwrite
