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


     
              
              
   

 

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:

 


  
         
         
        
  
  
         
         
        

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

4.如果还有什么需求,可以继续修改源码
