Reveal the "Circumflex Cache" framework in the Java class library: technical detailed explanation and usage guide Introduction: "Circumflex Cache" is a high -performance Java cache framework to accelerate data access and improve the response speed of the system.It provides a simple and easy -to -use API that can easily achieve cache function in Java applications.This article will introduce the technical details of the "Circumflex Cache" framework in detail, and at the same time provide guidelines for usage to help developers better understand and use the framework. 1. Technical explanation: 1. Principles of cache: "Circumflex Cache" framework is based on the cache principle of memory.When the application needs to access a certain data, it first query whether the data exists in the cache.If you exist, obtain it directly from the cache; if it does not exist, obtain data from the database or other data sources and store it in the cache for the next use. 2. Caches: "Circumflex Cache" framework provides a variety of cache strategies, and developers can configure according to actual needs.Common cache strategies include: -LRU (Least Recently Used): It is eliminated according to the recent time of the data. The recent data used in the cache is retained in the cache. -LFU (Least Frequently Used): It is eliminated according to the frequency of access to the data, the frequent data used in the cache is retained in the cache, and the rarely used data is replaced. -FIFO (First In, First Out): In the order of the earliest cache of the data, the data that enters the cache will be replaced first. 3. Monitoring and expiration: "Circumflex Cache" framework supports the use of monitoring cache and provides an expiration mechanism.Developers can set the expiration time of the cache data, and automatically remove the data from the cache after the setting time is achieved, thereby ensuring the freshness of the cache and the consistency of the data. 2. Use Guide: 1. Installation and configuration: Introduce the relevant jar package of the "Circumflex Cache" framework into the project, and perform related configuration in the configuration file of the project, including cache strategies, cache capacity, expiration time, etc. 2. Create a cache instance: Create a cache instance in the application, you can use the following code to implement: Cache<String, Object> cache = new Cache<>(); 3. Storage data: Use the `put` method to store the data into the cache, and you can set the expiration time of the data as needed. cache.put("key", value, expirationTime); 4. Get data: Use the `Get` method to get the data from the cache. Object value = cache.get("key"); 5. Delete data: Use the `Remove` method to delete the data from the cache. cache.remove("key"); 6. Clear cache: Use the `clear` method to clear all the data in the cache. cache.clear(); 7. Use the callback loading data: You can use the `ComputeiFabSEnt` method to load the data through the callback method when the data does not exist in the cache. Object value = cache.computeIfAbsent("key", () -> loadDataFromDataSource()); 3. Summary: The "Circumflex Cache" framework is a powerful and easy -to -use Java cache framework. It can significantly improve the performance and response speed of the application by using it.This article introduces the technical details of the framework and provides usian guidelines, hoping to help developers better understand and use the "Circumflex Cache" framework.Whether a complete programming code and related configuration need to be provided depends on the needs and actual situation of the reader.
