Yes, it is possible to generate a list of maps from MyBatis. MyBatis is a popular Java-based persistence framework that provides a flexible way to map Java objects to SQL statements. It allows you to retrieve data from a database and map it to various data structures, including a list of maps.
To generate a list of maps from MyBatis, you can use the resultMap feature. A resultMap is a mapping configuration that defines how the result of a SQL query should be mapped to Java objects or data structures. In this case, we can define a resultMap that maps the result to a list of maps.
Here is an example of how you can achieve this:
<resultMap id="mapResult" type="java.util.HashMap">
<result property="key1" column="column1"/>
<result property="key2" column="column2"/>
<!-- Add more result mappings for other columns -->
</resultMap>
<select id="getMapList" resultMap="mapResult">
SELECT column1, column2
FROM your_table
</select>
List<Map<String, Object>> mapList = yourMapper.getMapList();
In the above example, the resultMap with id "mapResult" is defined to map the columns "column1" and "column2" to the keys "key1" and "key2" in the resulting map. You can add more result mappings for other columns as needed.
This approach allows you to retrieve data from the database and store it in a list of maps, where each map represents a row of data with column names as keys and corresponding values. This can be useful when you need a more dynamic or flexible data structure to work with.
