mybatis generator自定义文件后缀名

现状及需求

使用mybatis generator自动生成文件，默认名都是XXXExample.java，XXXMapper.java，XXXMapper.xml，待过几个公司或者项目组的小伙伴就有感受，有的组要求是XXXDao.java，XXXCondition.java，XXXDao.xml，后来就自己调研能不能自定义文件后缀名，总不能每次自动生成好，再手动修改吧

解决办法

mybatis-generator-core-1.3.5.jar自带可以修改Example的文件名，generatorConfig.xml中添加如下配置项就ok了

<!--修改Example文件名-->
  <plugin type="org.mybatis.generator.plugins.RenameExampleClassPlugin">   
            <property name="searchString" value="Example$"/>  
            <property name="replaceString" value="Condition"/>  
   </plugin>

但是修改Mapper的后缀名却没有提供，这样的话就只能修改mybatis generator的源码，参照RenameExampleClassPlugin类，添加个RenameJavaMapperPlugin，RenameXmlMapperPlugin，然后自己生成个jar吧，姑且叫mybatis-generator-core-1.3.7.jar，

配置文件中继续添加如下配置：

<!--修改Mapper文件名-->
  <plugin type="org.mybatis.generator.plugins.RenameJavaMapperPlugin">
         <property name="searchString" value="Mapper$" />
         <property name="replaceString" value="Dao" />
        </plugin>
  <!--修改xml文件名-->
  <plugin type="org.mybatis.generator.plugins.RenameSqlMapperPlugin">
         <property name="searchString" value="Mapper" />
         <property name="replaceString" value="Dao" />
        </plugin>

 运行命令为：java -jar mybatis-generator-core-1.3.7.jar -configfile generatorConfig.xml -overwrite
