MyBatis Plus provides a convenient way to perform the `IN` query using XML configuration. Here's an example of how you can write the `IN` query using MyBatis Plus XML:
1. Define your mapper interface:
```java
public interface YourMapper extends BaseMapper<YourEntity> {
List<YourEntity> findBySomeProperty(@Param("list") List<String> values);
}
```
2. Create a mapper XML file (e.g., `YourMapper.xml`) and define the SQL statement:
```xml
<mapper namespace="com.example.YourMapper">
<select id="findBySomeProperty" resultType="com.example.YourEntity">
SELECT * FROM your_table WHERE some_property IN
<foreach collection="list" item="item" open="(" separator="," close=")">
#{item}
</foreach>
</select>
</mapper>
```
In the above example, `findBySomeProperty` method in your mapper interface accepts a list of values that you want to match against the `some_property` column in your table. The SQL statement uses the `<foreach>` tag to iterate over the list and generate the `IN` clause dynamically.
You can then invoke this method from your code to perform the `IN` query using MyBatis Plus. Remember to pass a valid list of values as an argument to the method.
Hope this helps! Let me know if you have any further questions.
