添加依赖

添加generatorConfig.xml文件

在maven的plugins中运行mybatis-generator插件

注意事项：

(1).generatorConfig.xml文件需要放在resource路径下。

================================================

1、添加依赖

<dependencies> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.2.8</version> </dependency> </dependencies> <!-- 控制 Maven 在构建过程中相关配置 --> <build> <!-- 构建过程中用到的插件 --> <plugins> <!-- 具体插件，逆向工程的操作是以构建过程中插件形式出现的 --> <plugin> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-maven-plugin</artifactId> <version>1.3.0</version> <!-- 插件的依赖 --> <dependencies> <!-- 逆向工程的核心依赖 --> <dependency> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-core</artifactId> <version>1.3.2</version> </dependency> <!-- 数据库连接池 --> <dependency> <groupId>com.mchange</groupId> <artifactId>c3p0</artifactId> <version>0.9.2</version> </dependency> <!-- MySQL 驱动 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.8</version> </dependency> </dependencies> </plugin> </plugins> </build>

2、添加generatorConfig.xml文件

<?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> <commentGenerator> <!-- 关闭自动生成的注释 --> <property name="suppressAllComments" value="true" /> </commentGenerator> <context id="DB2Tables" targetRuntime="MyBatis3"> <!--1.连接数据库--> <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://localhost:3306/project_crowd" userId="root" password="root"> </jdbcConnection> <javaTypeResolver > <property name="forceBigDecimals" value="false" /> </javaTypeResolver> <javaModelGenerator targetPackage="com.it.bean" targetProject="src/main/java"> <property name="enableSubPackages" value="true" /> <property name="trimStrings" value="true" /> </javaModelGenerator> <sqlMapGenerator targetPackage="com.it.dao" targetProject="src/main/java"> <property name="enableSubPackages" value="true" /> </sqlMapGenerator> <javaClientGenerator type="XMLMAPPER" targetPackage="com.it.dao" targetProject="src/main/java"> <property name="enableSubPackages" value="true" /> </javaClientGenerator> <table tableName="t_admin" domainObjectName="Admin" > </table> </context></generatorConfiguration>
