Learn about the technical principles and application scenarios of EHCACHE Spring Annitations Core framework

Learn about the technical principles and application scenarios of EHCACHE Spring Annitations Core framework EHCACHE is a popular Java cache framework that can provide high -performance object cache and cache management.The integration of it and the Spring framework makes it easier to use cache in Spring applications.The EHCACHE Spring Annotations Core framework is based on the EHCACHE and Spring framework, providing a set of annotations based on the cache declaration, which reduces the complexity of processing cache logic in the code. The technical principle of the EHCACACHE Spring Annotations Core framework is to manage the cache data by decoupled the cache logic and business logic to manage the cache data.It uses Spring's AOP (facing cut -out programming) and annotation support to simplify the configuration and use of cache. In EHCACHE Spring Annotations Core, there are several core annotations: -@Cacheable: For the resulting cache at the level level, the results of the indicator method can be cached, and the results can be directly obtained from the cache when the same parameter calls next time, instead of performing the actual method logic. -@Cachepput: For the configuration of the cache at the level level, the result of the indicator method should be cached, and the actual method logic is also executed. -@Cacheevict: For the configuration of the cache at the method level, the corresponding data should be removed from the cache after executing. By enabling the cache manager in the configuration file of the Spring application, and adding a corresponding annotation to the way to cache, the cache declare configuration can be achieved. The following is a sample code that shows how to use EHCACHE SPRING AnNotations Core framework: First, you need to configure the cache manager in the Spring configuration file: <bean id="cacheManager" class="org.springframework.cache.ehcache.EhCacheCacheManager"> <property name="cacheManager" ref="ehcache"/> </bean> <bean id="ehcache" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean"> <property name="configLocation" value="classpath:ehcache.xml"/> </bean> Then, add the corresponding annotation to the way to cache, as shown below: @Cacheable(value = "myCache", key = "#id") public MyObject getObjectById(String id) { // The actual method logic } In the above example, the @cacheable annotation is used to configure the cache, and the cache name is "MyCache", and the cache key is the method of parameter ID. When the GetObjectByid method is called, the EHCACHE Spring Annitations Core framework will automatically check whether there is data corresponding to the given ID in the cache.If so, return the data directly from the cache; if not, execute the actual method logic, and then put the result into the cache to prepare the next use. In addition to @cacheable annotations, you can also use @cachePut annotations to configure the cache, and perform the actual method logic at the same time.Use @cacheevict annotations to remove data in the cache. EHCACHE Spring Annotations Core framework is suitable for those application scenarios that need to cache a lot of data or high performance requirements.Configure the cache by declaration can reduce the complexity of the source code and improve development efficiency.In addition, through annotations, cache behaviors can be controlled more flexibly. To sum up, the EHCACHE Spring Annotations Core framework is a convenient and easy -to -use cache framework. By integration with the Spring framework, the annotation -based cache management is realized.Its technical principles are based on AOP and annotation support. It provides a flexible and scalable way to manage the cache data through decoupled cache logic and business logic.In the application scenario of high -performance and large data, the framework can be used to accelerate and optimize data access.
