Spring2..5整合Ehacahe

 在整合的過程當中真是報各類各樣的錯誤，其中最主要的就是jar包衝突以及不全，因此此文檔中把所須要的必須jar都列了出來

1，必須的jar

spring.jar spring-modules-cache.jar ehcache-core-2.4.6.jar

slf4j-api-1.5.6.jar slf4j-jdk-1.5.2.jar slf4-log4j-1.5.6.jar

oro-2.0.8.jar log4j-1.2.9.jar commons-logging-1.0.4.jar cglib-nodep-2.1_3.jar

asm-util-2.2.3.jar asm-commons-2.2.3.jar asm-2.2.3.jar

 

2，applicationContext.xml中的配置

 

<?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
        ">

        <!-- 使用EhcacheManager -->
        <bean id="cacheManager"
            class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean">
        <property name="configLocation" value="classpath:apEhcache.xml"/>
        </bean>

        <bean id="cacheProviderFacade" class="org.springmodules.cache.provider.ehcache.EhCacheFacade">
            <property name="cacheManager" ref="cacheManager"/>
        </bean>

        <!-- 配置方法攔截器 -->
        <!-- 緩存攔截器 -->
        <bean id="cachingInterceptor"  class="org.springmodules.cache.interceptor.caching.MethodMapCachingInterceptor">

        <property name="cacheProviderFacade" ref="cacheProviderFacade"/>
        <property name="cachingModels">
            <props>
                <!-- 全部StudentService對象中，以get開頭的方法都將進行緩存 -->
                <prop key="com.service.StudentService.get*">
                    cacheName=testCache
                </prop>
            </props>
        </property>
        </bean>
        <!-- 緩存刷新攔截器 -->
        <bean id="fulshingInterceptor" class="org.springmodules.cache.interceptor.flush.MethodMapFlushingInterceptor">
              <property name="cacheProviderFacade" ref="cacheProviderFacade"/>
              <property name="flushingModels">
                    <!-- 進行cache刷新（清除） -->
                    <props>
                        <prop key="com.service.StudentService.set*">
                            cacheNames=testCache
                        </prop>
                    </props>
              </property>
        </bean>

        <!-- 配置 基於BeanName規則的動態代理封裝 -->
        <bean class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">
            <property name="beanNames">
                <list>
                    <value>studentService</value>
                </list>
            </property>
            <property name="interceptorNames">
                <list>
                    <value>cachingInterceptor</value>
                    <value>fulshingInterceptor</value>
                </list>
            </property>
        </bean>

        <bean id="studentService" class="com.service.StudentService"></bean>
    </beans>

3，對緩存的配置（apEhcache.xml）

 

<?xml version="1.0" encoding="UTF-8"?>
    <ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:noNamespaceSchemaLocation="../config/ehcache.xsd">

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

        <defaultCache maxElementsInMemory="10000" eternal="false"
            timeToIdleSeconds="120" timeToLiveSeconds="120" overflowToDisk="true"
            maxElementsOnDisk="10000000" diskPersistent="false"
            diskExpiryThreadIntervalSeconds="120" memoryStoreEvictionPolicy="LRU" />
        <cache name="testCache"
            maxElementsInMemory="20000" maxElementsOnDisk="1000" eternal="true"
            overflowToDisk="true" memoryStoreEvictionPolicy="LFU" />
    </ehcache>

四、測試Service

 

package com.service;

        public class StudentService {

        private String name = "matthew";

            public String getName() {
                return name;
            }

            public String getName(String salution) {
                return salution + " " + name;
            }

            public void setName(String name) {
                this.name = name;
            }

            public void changeNameAndNotTellCache(String name) {
                this.name = name;
            }

        }

五、使用方法Clent

 

package com.service;

    import org.springframework.context.support.AbstractApplicationContext;
    import org.springframework.context.support.ClassPathXmlApplicationContext;

    public class TestCache {
        public static void main(String[] args) {
                  AbstractApplicationContext context;
                  context = new ClassPathXmlApplicationContext("classpath*:applicationContext.xml");
                  context.start();

                StudentService ss = (StudentService) context.getBean("studentService");
              n(name);
                 //update cache
                 System.out.println("清除緩存後，再次訪問 ");
                 ss.setName("Michael");
                 name = ss.getName();
                 System.out.println(name);

                name = ss.getName("Mr");
                 System.out.println(name);

                 context.close();
                 }
    }
