Caffeine Cache接入

Caffeine Cache接入

• Caffeine Cache，目前最快的Java内存框架，堆内存。

  • 接入方式：

    • 1.引入pom文件

      <dependency>
      <groupId>com.github.ben-manes.caffeine</groupId>
      <artifactId>caffeine</artifactId>
      <version>2.7.0</version>
      </dependency>
      <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-cache</artifactId>
      </dependency>
      

    • 2.编写CaffeineConfig并注入CacheManager

      import org.springframework.cache.CacheManager;
      import org.springframework.cache.annotation.CachingConfigurerSupport;
      import org.springframework.cache.annotation.EnableCaching;
      import org.springframework.cache.caffeine.*;
      import org.springframework.context.annotation.Bean;
      import org.springframework.context.annotation.Configuration;
      import com.github.benmanes.caffeine.cache.Caffeine;
                  
      import java.util.concurrent.TimeUnit;
                  
      @Configuration
      @EnableCaching
      public class CaffeineConfig extends CachingConfigurerSupport {
                  
          @Bean
          public CacheManager caffeineCacheManager() {
              CaffeineCacheManager cacheManager = new CaffeineCacheManager();
              //定制化缓存Cache
              cacheManager.setCaffeine(Caffeine.newBuilder()
                      .expireAfterWrite(3, TimeUnit.MINUTES)
                      .initialCapacity(100)
                      .maximumSize(10000))
              ;
              return cacheManager;
          }
      }
      

    • 3.通过注解使用

      @Cacheable(cacheNames = "cache name", key = "#patam1+'-'+#param2")
      public void test(String param1,String param2){
      }
