MyBatis_Generator_Eclipse 插件安装使用
下载安装
1、下载MyBatis_Generator_Eclipse_1.3.1。
2、解压压缩文件，将features中的jar包复制到eclipse的features中，将plugins中的jar包复制到eclipse中plugins中
3、重启eclipse
生成代码
新建generatorConfig.xml文件
和pom.xml放在同一层
<?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 > <!-- location的值为本地数据库驱动 --> <classPathEntry location="F:/oracle11g/ojdbc6.jar" /> <context id="context1" > <!-- jdbc:oracle:thin:@Oracle服务的地址:开放的接口:服务名 userId="用户名" password="密码" --> <jdbcConnection driverClass="oracle.jdbc.driver.OracleDriver" connectionURL="jdbc:oracle:thin:@localhost:1521:Orcl" userId="root" password="root" /> <!-- bean类的地址 --> <javaModelGenerator targetPackage="com.trade.bean" targetProject="trade/src/main/java" /> <!-- mapper.xml的地址 --> <sqlMapGenerator targetPackage="sql.oracle.trade" targetProject="trade/src/main/resources" /> <!-- mapper接口的地址 --> <javaClientGenerator targetPackage="com.trade.dao" targetProject="trade/src/main/java" type="XMLMAPPER" /> <!-- 对应的表 --> <table schema="Student" tableName="TMP_CHENKAIXIN_20171031"></table> </context></generatorConfiguration>写好上述文件后，在目录中右键generatorConfig.xml文件出现下图
