添加依賴 添加generatorConfig.xml文件 在maven的plugins中運行mybatis-generator插件 注意事項： (1).generatorConfig.xml文件需要放在resource路徑下。

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

1、添加依賴

<dependencies> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.2.8</version> </dependency> </dependencies> <!-- 控制 Maven 在構建過程中相關配置 --> <build> <!-- 構建過程中用到的插件 --> <plugins> <!-- 具體插件，逆向工程的操作是以構建過程中插件形式出現的 --> <plugin> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-maven-plugin</artifactId> <version>1.3.0</version> <!-- 插件的依賴 --> <dependencies> <!-- 逆向工程的核心依賴 --> <dependency> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-core</artifactId> <version>1.3.2</version> </dependency> <!-- 數據庫連接池 --> <dependency> <groupId>com.mchange</groupId> <artifactId>c3p0</artifactId> <version>0.9.2</version> </dependency> <!-- MySQL 驅動 --> <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> <!-- 關閉自動生成的注釋 --> <property name='suppressAllComments' value='true' /></commentGenerator> <context targetRuntime='MyBatis3'> <!--1.連接數據庫--> <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>
