1.创建测试工程
选择maven Project
点击next
填写项目名称
点击 finish 项目创建完成
2.pom.xml
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.demo</groupId> <artifactId>mybatis_generator</artifactId> <version>0.0.1-SNAPSHOT</version> <name>mybatis_generator</name> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> </properties> <dependencies> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.35</version> </dependency> <dependency> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-core</artifactId> <version>1.3.2</version> </dependency> </dependencies> <build> <pluginManagement> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>1.7</source> <target>1.7</target> </configuration> <version>3.3</version> </plugin> <plugin> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-maven-plugin</artifactId> <version>1.3.2</version> <dependencies> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.35</version> </dependency> </dependencies> <configuration> <!--配置文件的路径--> <configurationFile>${basedir}/src/main/resources/generatorConfig.xml</configurationFile> <overwrite>true</overwrite> </configuration> </plugin> </plugins> </pluginManagement> </build> </project>
3.在resource下创建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> <context id="test" targetRuntime="MyBatis3"> <plugin type="org.mybatis.generator.plugins.EqualsHashCodePlugin"></plugin> <plugin type="org.mybatis.generator.plugins.SerializablePlugin"></plugin> <plugin type="org.mybatis.generator.plugins.ToStringPlugin"></plugin> <commentGenerator> <!-- 这个元素用来去除指定生成的注释中是否包含生成的日期 false:表示保护 --> <!-- 如果生成日期,会造成即使修改一个字段,整个实体类所有属性都会发生变化,不利于版本控制,所以设置为true --> <property name="suppressDate" value="true" /> <!-- 是否去除自动生成的注释 true:是 : false:否 --> <property name="suppressAllComments" value="false" /> </commentGenerator> <!--数据库链接URL,用户名、密码 --> <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://数据库链接URL" userId="用户名" password="密码"> </jdbcConnection> <javaTypeResolver> <!-- This property is used to specify whether MyBatis Generator should force the use of java.math.BigDecimal for DECIMAL and NUMERIC fields, --> <property name="forceBigDecimals" value="false" /> </javaTypeResolver> <!-- 生成模型的包名和位置 --> <javaModelGenerator targetPackage="entity" targetProject="src/main/java/"> <property name="enableSubPackages" value="true" /> <property name="trimStrings" value="true" /> </javaModelGenerator> <!-- 生成映射文件的包名和位置 --> <sqlMapGenerator targetPackage="mapping" targetProject="src/main/resources/"> <property name="enableSubPackages" value="true" /> </sqlMapGenerator> <!-- 生成DAO的包名和位置 --> <javaClientGenerator type="XMLMAPPER" targetPackage="dao" implementationPackage="src/main/java/" targetProject="src/main/java/"> <property name="enableSubPackages" value="true" /> </javaClientGenerator> <!-- 要生成哪些表 --> <table tableName="user" domainObjectName="user" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table> </context> </generatorConfiguration>
4.下载maven依赖包 update project
5.依赖包加载完后,项目run as->Maven build, 执行mybatis-generator:generate命令,生成文件
在控制台 显示 build success,说明文件已经创建成功了:
如果发现文件没显示出来 刷新一下工程就可以了。
6 .生成的文件
备注:generatorConfig.xml中的url地址如果有&替换成&
