mybatis java.lang.UnsupportedOperationException

mybatis 的mapper配置的select查询语句,报java.lang.UnsupportedOperationException

内容如下:

org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.exceptions.PersistenceException:
### Error querying database. Cause: java.lang.UnsupportedOperationException
### The error may exist in file [D:java omcatapache-tomcat-7.0.68webappsROOTWEB-INFclassesmapperusinessTProProductMapper.xml]
### The error may involve com.lincomb.manager.business.mapper.TProProductMapper.exprotceneProduct
### The error occurred while handling results
### SQL: SELECT 【 中间省略若干sql 】 DESC
### Cause: java.lang.UnsupportedOperationException

这个是由于mapper.xml 的select配置的

把resultType改为List集合的对象就好了
