解決mybatis-generator生成的Mapper文件中沒有Selective結尾的方法

一開始從網上找的generatorConfig.xml內容如下：

<!-- 配置生成器 -->
<generatorConfiguration>
    <!--執行generator插件生成文件的命令： call mvn mybatis-generator:generate -e -->
    <!-- 引入配置文件 -->
    <properties resource="mybatis-generator/mybatisGeneratorInit.properties"/>

發現運行生成代碼的maven插件后，Mapper.java和Mapper.xml中都沒有Selective結尾的方法(insertSelective、updateByPrimaryKeySelective)。

后來發現是context標簽的targetRuntime屬性的原因，將其設置為MyBatis3即可。
