1.实现步骤:
9.1 加载插件
<!-- mybatis逆向工程jar包 -->
<dependency>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-core</artifactId>
<version>1.3.2</version>
</dependency>
</dependencies>
<build> <plugins> <plugin> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-maven-plugin</artifactId> <version>1.3.5</version> <configuration> <!--配置文件的路径--> <configurationFile>src/main/resources/generatorConfig.xml</configurationFile> <overwrite>true</overwrite> </configuration> <dependencies> <dependency> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-core</artifactId> <version>1.3.5</version> </dependency> </dependencies> </plugin> </plugins> </build>
9.2 设置配置文件
<?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"> <!-- 配置生成器 --> <generatorConfiguration> <!--数据库驱动jar --> <classPathEntry location="F:\1000phone\jar\mysql驱动\mysql-connector-java-5.0.8-bin.jar" /> <context id="MyBatis" targetRuntime="MyBatis3">
<!-- 一些工具 -->
<!-- <plugin type="org.mybatis.generator.plugins.EqualsHashCodePlugin"></plugin>-->
<plugin type="org.mybatis.generator.plugins.SerializablePlugin"></plugin>
<!--<plugin type="org.mybatis.generator.plugins.ToStringPlugin"></plugin>--> <!--去除注释 --> <commentGenerator> <property name="suppressAllComments" value="true" /> </commentGenerator> <!--数据库连接 --> <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://localhost:3306/chaoshi" userId="root" password="123456"> </jdbcConnection> <!--生成实体类 指定包名 以及生成的地址 (可以自定义地址,但是路径不存在不会自动创建 使用Maven生成在target目录下,会自动创建) --> <javaModelGenerator targetPackage="com.qf.bean" targetProject="F:\1000phone\three\workspace\mybatis_0929\src\main\java"> <property name="trimStrings" value="true" /> </javaModelGenerator> <!--生成SQLmapper文件 --> <sqlMapGenerator targetPackage="mapper" targetProject="F:\1000phone\three\workspace\mybatis_0929\src\main\resources"> </sqlMapGenerator> <!--生成Dao文件,生成接口 --> <javaClientGenerator type="XMLMAPPER" targetPackage="com.qf.dao" targetProject="F:\1000phone\three\workspace\mybatis_0929\src\main\java"> </javaClientGenerator> <table tableName="student" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"> </table> <table tableName="grade" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"> </table> <table tableName="subject" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"> </table> </context> </generatorConfiguration>
9.3运行:maven Project选项卡->plugins->找到mybatis-generator-core,双击运行就会自动生成
