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
