MyBatis supports JSON queries through its dynamic SQL feature. To perform a JSON query with MyBatis, you can use the `<![CDATA[ ]]>` section to include the JSON query inside your SQL statement. Here's an example:
```xml
<select id="getUsersByJsonQuery" resultType="User">
SELECT * FROM users
WHERE JSON_CONTAINS(details, <![CDATA[#{jsonQuery}]]>)
</select>
```
In this example, we have a table called "users" with a column named "details" that stores JSON data. The `JSON_CONTAINS` function is used to check if any JSON object in the "details" column matches the provided JSON query.
To use this query in your Java code, you need to define a corresponding method in your MyBatis mapper interface:
```java
@Select("getUsersByJsonQuery")
List<User> getUsersByJsonQuery(String jsonQuery);
```
You can then call this method and pass your JSON query as a parameter to retrieve the desired results.
Note that the exact syntax and functions may vary depending on the database you are using with MyBatis. Make sure to refer to your database's documentation for specific JSON querying capabilities.
