使用GuavaCache可以快速建立缓存
1.需要在启动类上注解@EnableCaching
2.配置CacheManager
3.控制器上注解使用@Cacheable
pom.xml
org.springframework.boot spring-boot-starter-parent 1.5.9.RELEASE UTF-8 UTF-8 1.8 org.springframework.boot spring-boot-starter-web org.springframework spring-context-support 4.3.9.RELEASE com.google.guava guava 18.0 org.apache.maven.plugins maven-compiler-plugin 1.8 1.8 UTF-8
CacheConfig.java 配置类
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 控制器测试类
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取得参数，根据参数name作为缓存的key，value是使用的缓存list中的那个，具体看配置类
@Cacheable(value = "GuavaCacheAll",key = "#name")
public String tt(String name){
System.out.println("in tt");
return "name:"+name;
}
}Application.java springboot启动类
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);
}
}看完上述内容，你们掌握怎么在springboot中使用GuavaCache处理缓存的方法了吗？如果还想学到更多技能或想了解更多相关内容，欢迎关注创新互联行业资讯频道，感谢各位的阅读！
