ehcache 缓存使用

1配置类

@Configuration

@EnableCachingpublic class EhcacheConfig {    @Bean(name = "appEhCacheCacheManager")    public EhCacheCacheManager ehCacheCacheManager(){        EhCacheManagerFactoryBean bean=ehCacheManagerFactoryBean();        return new EhCacheCacheManager (bean.getObject ());    }    @Bean    public EhCacheManagerFactoryBean ehCacheManagerFactoryBean(){        EhCacheManagerFactoryBean cacheManagerFactoryBean = new EhCacheManagerFactoryBean ();        cacheManagerFactoryBean.setConfigLocation (new ClassPathResource("ehcache.xml"));        cacheManagerFactoryBean.setShared (true);        return cacheManagerFactoryBean;    }}

2调用service层

@Controller@RequestMapping("/home/main")public class HomeController {    @Autowired    HelloService helloService;    @RequestMapping("/show")    @ResponseBody    public String showHello(){        System.out.println(helloService.cacheService("1"));        System.out.println(helloService.cacheService("2"));        System.out.println(helloService.cacheService("1"));        System.out.println(helloService.cacheService("2"));        return rtn;

}}3service层方法加上@cacheable注解

@Servicepublic class HelloService {    @Cacheable(value = "helloworld", key="#id")    public  String cacheService(String id){        System.out.println("excuteing blllaaaaaa");        return id+"_value";    }}4运行结果

excuteing blllaaaaaa
1_value
excuteing blllaaaaaa
2_value
1_value
2_value
