Updating boot cache
In our case the key is created based on the input parameter and the value is the outcome of the method, but it does not have to be that simple.The cache abstraction provided by Spring allows for much more, but this is a topic for a different post.Each of us met the situation when application was working slowly.Even the best code will fall on knees at high load.For more information and complete documentation, see Spring's caching reference.Feel free to leave a comment if you have any questions or run into any problems.Caching Configurer Support; import org.springframework.cache.interceptor. This is a simple example of how to cache application data in your Redis instance.Although this post focuses on caching with Redis, caching with other providers is very straightforward and the caching concepts remain the same.
Like I mentioned at the start of the article, I will be using Ehcache.
The examples in this post use Spring 4.1.3 and Spring Data Redis 1.4.1, the latest versions at the time of this writing. You'll need to install the import org.springframework.cache. See the following example: import org.apache.log4j. Logger; import org.springframework.cache.annotation. The parameters to your method become the key in your cache store.
Cache Manager; import org.springframework.cache.annotation. Caching Configurer Support; import org.springframework.cache.annotation. Enable Caching; import org.springframework.context.annotation. Bean; import org.springframework.context.annotation. For example, in the following method, the value for the parameter // Previous imports omitted import org.springframework.cache.annotation. Method; @Configuration @Enable Caching public class Cache Config extends Caching Configurer Support Now when your method results are cached, they will be cached with your custom key generator implementation.
In this article I will demonstrate how the cache abstraction works using Ehcache as the actual cache implementation.
In this example I will be creating a simple REST service. In this example I’ll create a simple REST API, so let’s add Web and Cache as dependencies.
