在Springboot应用中整合mybatis时遇到错误：org.springframework.beans.factory.UnsatisfiedDependencyException，主要原因是Mapped Statements collection已经包含某个值。错误详细堆栈信息显示为：Mapped Statements collection already contains value for com.nice.mapper.QuestionMapper.list。解决办法是检查并修改com/nice/mapper/QuestionMapper.java中的重复映射方法，避免方法名冲突。

解决方案:mapper的方法重复,替换一个方法名即可。
