In Java, there are various caching libraries or frameworks that can be used to store data in a cache. Two popular options are:<\/p>\n

Use Ehcache:<\/p>\n

Ehcache is a powerful open source Java caching library. Firstly, you must add the Ehcache dependency to your project. Next, create a cache configuration file (ehcache.xml) that defines the properties and rules of the cache. Then, use the Ehcache API to create a cache instance in your code and store data in the cache. Here is an example code:<\/p>\n

import net.sf.ehcache.Cache;
<\/p>
import net.sf.ehcache.CacheManager;<\/p>
import net.sf.ehcache.Element;<\/p>
\/\/ \u521b\u5efa\u7f13\u5b58\u7ba1\u7406\u5668<\/p>
CacheManager cacheManager = CacheManager.create();<\/p>
\/\/ \u83b7\u53d6\u6216\u521b\u5efa\u7f13\u5b58\u5b9e\u4f8b<\/p>
Cache cache = cacheManager.getCache(\"myCache\");<\/p>
\/\/ \u5c06\u6570\u636e\u5b58\u50a8\u5230\u7f13\u5b58\u4e2d<\/p>
Element element = new Element(\"key\", \"value\");<\/p>
cache.put(element);<\/p>
\/\/ \u4ece\u7f13\u5b58\u4e2d\u83b7\u53d6\u6570\u636e<\/p>
Element result = cache.get(\"key\");<\/p>
Object value = result.getObjectValue();<\/p>
\/\/ \u5173\u95ed\u7f13\u5b58\u7ba1\u7406\u5668<\/p>
cacheManager.shutdown();<\/p><\/pre>\n
Using Caffeine:<\/p>\n
Caffeine is another popular Java caching library known for its high performance and low latency. To start, you’ll need to add Caffeine as a dependency in your project. Then, in your code, use the Caffeine API to create a cache instance and store data in the cache. Here is an example code snippet:<\/p>\n
import com.github.benmanes.caffeine.cache.Cache;
<\/p>
import com.github.benmanes.caffeine.cache.Caffeine;<\/p>
\/\/ \u521b\u5efa\u7f13\u5b58\u5b9e\u4f8b<\/p>
Cache<String, Object> cache = Caffeine.newBuilder()<\/p>
        .maximumSize(100)<\/p>
        .build();<\/p>
\/\/ \u5c06\u6570\u636e\u5b58\u50a8\u5230\u7f13\u5b58\u4e2d<\/p>
cache.put(\"key\", \"value\");<\/p>
\/\/ \u4ece\u7f13\u5b58\u4e2d\u83b7\u53d6\u6570\u636e<\/p>
Object value = cache.getIfPresent(\"key\");<\/p>
\/\/ \u6e05\u7a7a\u7f13\u5b58<\/p>
cache.invalidateAll();<\/p><\/pre>\n
These are examples of two commonly used Java cache libraries. You can choose the cache solution that suits your project’s needs and store data according to the corresponding API.<\/p>\n","protected":false},"excerpt":{"rendered":"
