遇到的问题：

maven INSTINCT 提示乱码，GBK之类的；

pom文件新增代码解决：

    <properties>  
 <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>  
</properties>  

2、mybatis中提示 Mapped Statements collection already contains value

[D:\apache-tomcat-msg\webapps\dataService\WEB-INF\classes\cn\creditharmoney\td\dao\impl\DetailsListDaoMapper.xml]'; nested exception is org.apache.ibatis.builder.BuilderException: Error parsing Mapper XML. Cause: java.lang.IllegalArgumentException: Mapped Statements collection already contains value for cn.creditharmoney.td.dao.DetailsListDao.insertAssociationPartner

是因为map的xml中存在两个一样的id造成的，删除一个即可。
