XML fragments parsed from previous mappers already

1. ssm项目报错：

WARN [main] DefaultListableBeanFactory:1479-- Bean creation exception on FactoryBean type check: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'eat10Ivs03CreditAntifraudVerifyResultMapper' defined in file [\Eat10Ivs03CreditAntifraudVerifyResultMapper.class]: Cannot resolve reference to bean 'sqlSessionFactory' while setting bean property 'sqlSessionFactory'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sqlSessionFactory' defined in file [D:\projects\idea_ngit\datasource-dsthirdpart\target\classes\spring\spring-dao.xml]: Invocation of init method failed; nested exception is org.springframework.core.NestedIOException: Failed to parse mapping resource: 'file [\Eax01JxlIouMapper.xml]'; nested exception is java.lang.RuntimeException: Error parsing Mapper XML. Cause: java.lang.IllegalArgumentException: XML fragments parsed from previous mappers already contains value for ***.Eax01JxlIouMapper.Column_List

XML fragments parsed from previous mappers already contains value for ***.Eax01JxlIouMapper.Column_List

主要原因就在于 namespace， 检查mybatis的配置文件： Eax01JxlIouMapper.xml中跟别的xml中有相同的namespace， 导致此问题。
