怎么在springboot中使用GuavaCache處理緩存?相信很多沒有經(jīng)驗的人對此束手無策,為此本文總結(jié)了問題出現(xiàn)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
pom.xml
<parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.5.9.RELEASE</version> </parent> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>4.3.9.RELEASE</version> </dependency> <dependency> <groupId>com.google.guava</groupId> <artifactId>guava</artifactId> <version>18.0</version> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>1.8</source> <target>1.8</target> <encoding>UTF-8</encoding> </configuration> </plugin> </plugins> </build>
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(shù),根據(jù)參數(shù)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); } }
