Enable MyBatis Second-Level Cache: Step-by-Step Guide
To enable the second-level cache in MyBatis, you need to make the appropriate configuration in the MyBatis configuration file (such as mybatis-config.xml). Below are the steps to enable the second-level cache in MyBatis:
- Enable the switch for secondary cache for elements. Example is as follows:
<setting name="cacheEnabled" value="true"/>
- Add the following annotation to the mapper interface where secondary caching is needed:
@CacheNamespace
In this way, you can enable the MyBatis second-level cache. It is important to note that the second-level cache is enabled by default, but in a distributed environment, there may be some issues with the second-level cache. Therefore, when using the second-level cache, pay attention to properly configure the cache expiration and refresh strategy to avoid inconsistencies in data.
