由于原项目中系统登录用户表中新添加了字段来关联其他表,但原来的mapper和bean就得重新再逆向出来,逆向后,就参照着原来你mapper来添加一些自定义在mapper的方法,那么接下来就爆出异常了
这个异常是由于同一id的方法在mapper中已经定义了,导致在mapper中重复定义
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'outMoneyServiceImpl': Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'permissionsSystemUserDao' defined in URL [jar:file:/E:/workspace/weidongdaojia-wddj-web/wddj-web-dev/wddj-web/target/wddj-web/WEB-INF/lib/wddj-manager-mapper-0.0.1-SNAPSHOT.jar!/com/wddj/manager/dao/PermissionsSystemUserDao.class]: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: org.apache.ibatis.builder.BuilderException: Error parsing Mapper XML.

二丶逆向工程时的问题
java.lang.IllegalArgumentException: Result Maps collection does not contain value for com.zm.model.User
at org.apache.ibatis.session.Configuration$StrictMap.get(Configuration.java:860)
at org.apache.ibatis.session.Configuration.getResultMap(Configuration.java:612)
at org.apache.ibatis.builder.MapperBuilderAssistant.getStatementResultMaps(MapperBuilderAssistant.java:344)
Mybatis “java.lang.IllegalArgumentException:
Result Maps collection already contains value for com.....Class...BaseResultMap
相同的两个返回基本信息。。。解决方法。。在所有的项目查找 看ID 为BaseResultMap 和Type的Class对应的类，有相同的。就会出现这种现象 ；
删除其中其中一个XML文件，或更新类。。
原理：应该是Mybatis与Spring集成后，解析XML时。可共用一个IOC容器。。
