mybatis-generator插件和TKmybatis的结合使用



mybatis-generator可以自动生成mapper和entity文件，mybatis-generator有三种用法：命令行、eclipse插件、maven插件。这里使用的是maven插件方式，可以在eclipse/intellij idea等ide上可以通用。

TKmybatis提供一种通用mapper，它不需要针对每个mapper写sql语句，只需继承通用mapper调用相应的接口来完成单表的增删改查。

 

配置步骤：

1.pom文件中增加代码：

<plugin>                <groupId>org.mybatis.generator</groupId>                <artifactId>mybatis-generator-maven-plugin</artifactId>                <version>${mybatis.generator.version}</version>                <configuration>                    <configurationFile>src/main/resources/conf/generatorConfig.xml</configurationFile>                    <verbose>true</verbose>                    <overwrite>true</overwrite>                </configuration>                <dependencies>                    <dependency>                        <groupId>org.mybatis.generator</groupId>                        <artifactId>mybatis-generator-core</artifactId>                        <version>${mybatis.generator.version}</version>                    </dependency>                    <dependency>                        <groupId>tk.mybatis</groupId>                        <artifactId>mapper</artifactId>                        <version>${tk.mybatis.version}</version>                    </dependency>                </dependencies>        </plugin><properties>        <!-- MyBatis Generator -->        <mybatis.generator.version>1.3.2</mybatis.generator.version>        <targetJavaProject>${basedir}/src/main/java</targetJavaProject>        <targetMapperPackage>com.wdcloud.fayu.mapper</targetMapperPackage>        <targetEntityPackage>com.wdcloud.fayu.entity</targetEntityPackage>        <!-- tk.mybatis -->        <tk.mybatis.version>3.3.6</tk.mybatis.version>        <persistence.version>1.0</persistence.version>　　　　 <mapper.plugin>tk.mybatis.mapper.generator.MapperPlugin</mapper.plugin>        <mapper.Mapper>tk.mybatis.mapper.common.Mapper</mapper.Mapper></properties>　　　　　        <!--通用Mapper -->        <dependency>            <groupId>tk.mybatis</groupId>            <artifactId>mapper</artifactId>            <version>${tk.mybatis.version}</version>        </dependency>        <!-- eitity注解 -->        <dependency>            <groupId>javax.persistence</groupId>            <artifactId>persistence-api</artifactId>            <version>${persistence.version}</version>        </dependency>

 

2.创建配置文件generatorConfig.xml，代码如下：

<?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>     <properties resource="conf/config.properties"/>         <!-- 数据库驱动包位置 -->      <classPathEntry          location="D:\程序\mysql-5.6.26-winx64\mysql-connector-java-5.1.17.jar" />        <context id="Mysql" targetRuntime="MyBatis3Simple" defaultModelType="flat">        <!-- TKmybatis配置 -->        <property name="javaFileEncoding" value="UTF-8"/>        <property name="beginningDelimiter" value="`"/>        <property name="endingDelimiter" value="`"/>        <plugin type="${mapper.plugin}">          <property name="mappers" value="${mapper.Mapper}"/>        </plugin>             <commentGenerator>              <!-- 是否去除自动生成的注释 true：是 ： false:否 -->            <property name="suppressAllComments" value="true"/>          </commentGenerator>          <!-- 数据库链接URL、用户名、密码 -->          <jdbcConnection driverClass="${jdbc.driver}"              connectionURL="${jdbc.url}" userId="${jdbc.username}" password="${jdbc.password}" />          <!-- 生成模型的包名和位置 -->          <javaModelGenerator targetPackage="${targetEntityPackage}" targetProject="${targetJavaProject}" />          <!-- 生成的映射文件包名和位置 -->          <sqlMapGenerator targetPackage="${targetMapperPackage}" targetProject="${targetJavaProject}" />          <!-- 生成service的包名和位置 -->          <javaClientGenerator targetPackage="${targetMapperPackage}" targetProject="${targetJavaProject}" type="XMLMAPPER" />          <!-- 要生成的那些表 -->          <table tableName="wd_resource" domainObjectName="WdResource" >            <generatedKey column="id" sqlStatement="Mysql" identity="true"/>                    </table>        <table tableName="wd_course" domainObjectName="WdCourse" >            <generatedKey column="id" sqlStatement="Mysql" identity="true"/>                    </table>        <table tableName="wd_solr" domainObjectName="WdSolr" >              <generatedKey column="id" sqlStatement="Mysql" identity="true"/>                      </table>    </context>  </generatorConfiguration> 

${targetEntityPackage}等在pom文件的properties中做了配置。

 

3.修改applicationContext.xml的MapperScannerConfigurer，代码如下：

　　<!-- 自动扫描注册Mybatis mapper -->    <!-- <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property         name="basePackage" value="com.wdcloud.fayu.mapper" /> </bean> -->                <!-- TKmybatis自动扫描注册Mybatis mapper -->    <bean class="tk.mybatis.spring.mapper.MapperScannerConfigurer">        <property name="basePackage" value="com.wdcloud.fayu.mapper"/>    </bean>

 

最后使用maven命令即可使用：

mvn mybatis-generator:generate
