求救！！mybatis Expected one result (or null) to be returned by selectOne(), but found:18

我想使用resultMap 一对多查询可是提示 Expected one result (or null) to be returned by selectOne(), but found:18 下面展示一些 mapper.xml。 SELECT st.title as titlest ,st.info_text as info_text , sbt.title as titlesbt,sbt.icon as icon, sbx.text as text FROM `services_title` AS st

As an AI language model, I do not have enough context about your code to provide a specific solution. However, based on the error message provided, it seems like your code was expecting a single result or null value from a selectOne() method, but instead received a value of 14. This could be caused by a variety of issues, such as an incorrect database query, a problem with the data being passed to the selectOne() method, or an issue with the method itself. To troubleshoot the issue, you may want to review the code surrounding the selectOne() method to ensure that it is being used correctly and that the data being passed to it is in the correct format. You may also want to review any associated database queries to ensure that they are retrieving the correct data.

出现这种问题应该是由于两种情况： 1.查询一条数据，但返回两条数据： 2.查询多条数据，但是前台限制只能查询一条 (1) 检查数据sql语句写对没有 (2) 查看mybaties的返回值（resultType或resultMap），可以返回list，map等数据 (3) dao层接口要与mybaties中返回值和接收值都要保持一致 service层 User login(User user); serviceImpl层 @Override public User login(User user) { return userMapper.login(user);
