怎么在springboot中使用GuavaCache處理緩存

怎么在springboot中使用GuavaCache處理緩存？相信很多沒有經驗的人對此束手無策，為此本文總結了問題出現的原因和解決方法，通過這篇文章希望你能解決這個問題。

使用GuavaCache可以快速建立緩存

1.需要在啟動類上注解@EnableCaching
2.配置CacheManager
3.控制器上注解使用@Cacheable

CacheConfig.java 配置類

package application.config;

import com.google.common.cache.CacheBuilder;
import org.springframework.cache.CacheManager;
import org.springframework.cache.guava.GuavaCache;
import org.springframework.cache.support.SimpleCacheManager;
import org.springframework.context.annotation.Configuration;

import java.util.ArrayList;
import java.util.List;
import java.util.concurrent.TimeUnit;

@Configuration
public class CacheConfig {

  public CacheManager cacheManager(){
    GuavaCache guavaCache = new GuavaCache("GuavaCacheAll", CacheBuilder.newBuilder()
    .recordStats()
    .expireAfterWrite(10000, TimeUnit.SECONDS)
    .build());

    List list = new ArrayList();
    list.add(guavaCache);
    SimpleCacheManager simpleCacheManager = new SimpleCacheManager();
    simpleCacheManager.setCaches(list);
    return simpleCacheManager;
  }
}

TestController.java 控制器測試類

package application.controller;

import org.springframework.cache.annotation.Cacheable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;


@RestController
public class TestController {

  @RequestMapping("/test")
  //key是使用spEl取得參數，根據參數name作為緩存的key，value是使用的緩存list中的那個，具體看配置類
  @Cacheable(value = "GuavaCacheAll",key = "#name")
  public String tt(String name){
    System.out.println("in tt");
    return "name:"+name;
  }
}

Application.java springboot啟動類

package application;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cache.annotation.EnableCaching;

@SpringBootApplication
@EnableCaching
public class Application {
  public static void main(String[] args) {
    SpringApplication.run(Application.class,args);
  }
}
