Question

这是我的实际方法。

当我逐秒刷新我的应用程序时，日期参数始终是更新。

控制器

@Controller
public class MainController implements ToCache {

    @RequestMapping(value = {"/", "/index"})
    @Cacheable(value = "main", key = "#root.method.name")
    public String showHome(HttpServletRequest request) {

        request.setAttribute("now", new Date());
        request.setAttribute("tmp", System.getProperty("java.io.tmpdir"));

        return "index";
    }

}

界面

public interface ToCache {

    String showHome(HttpServletRequest request);

}

的Ehcache-servlet.xml中

    <mvc:annotation-driven />

    <context:component-scan base-package="com.pjcom.**" />

    <!-- Manejador de vistas -->
    <bean id="viewResolver"
          class="org.springframework.web.servlet.view.InternalResourceViewResolver"
          p:prefix="/WEB-INF/view/"
          p:suffix=".jsp"
          p:exposeContextBeansAsAttributes="true" />

Ehcache与Spring的集成

applicationContext.xml中

<bean id="cacheManager" class="org.springframework.cache.ehcache.EhCacheCacheManager">
    <property name="cacheManager" ref="ehcache"/>
</bean>

<bean id="ehcache" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean">
    <property name="configLocation" value="classpath:ehcache.xml"/>
    <property name="shared" value="true"/>
</bean>

<bean id ="enhancedDefaultKeyGenerator" class="org.springframework.cache.interceptor.DefaultKeyGenerator"/>

<cache:annotation-driven mode="proxy" 
                         proxy-target-class="true" 
                         cache-manager="cacheManager" 
                         key-generator="enhancedDefaultKeyGenerator"/>

<!-- END EHCACHE -->

Ehcache配置

<?xml version="1.0" encoding="UTF-8"?>
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:noNamespaceSchemaLocation="http://ehcache.org/ehcache.xsd" 
         updateCheck="true" 
         monitoring="autodetect" 
         dynamicConfig="true"
         maxBytesLocalHeap="150M">

    <diskStore path="java.io.tmpdir"/>    

    <cache name="main"
           maxBytesLocalHeap="100M"
           eternal="false"
           t

imeToIdleSeconds="10"
           timeToLiveSeconds="10"
           overflowToDisk="true"
           maxElementsOnDisk="1000"          
           memoryStoreEvictionPolicy="LRU"/>

</ehcache>

运行时日志，部署和刷新。

Ehcache在Spring 3.2中不起作用
