mybatis返回map<list>

MyBatis can return a Map<List> by configuring the result map appropriately. Here are the steps to achieve this:

Define a ResultMap in your MyBatis configuration XML file:

Use the defined ResultMap in your SQL query:
<select id="yourQuery" resultMap="myResultMap">
<!-- your SQL query -->
</select>

In your Java code, retrieve the result as a Map<List>:
Map<String, List<YourClass>> resultMap = sqlSession.selectOne("yourQuery");
List<YourClass> myList = resultMap.get("myList");

Make sure to replace your.package.YourClass with the appropriate class that represents the elements of the list you want to retrieve.
