Spring MVC 4.+ 使用 Ehcache 超简单配置！！！

First

pom.xml

<dependency>
    <groupId>net.sf.ehcache</groupId>
    <artifactId>ehcache-core</artifactId>
    <version>2.6.11</version>
</dependency>


<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context-support</artifactId>
    <version>4.2.3.RELEASE</version>
</dependency>

Second

create new file cache-config.xml

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

    <cache:annotation-driven cache-manager="cacheManager"/>

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

    <bean id="cacheManager" class="org.springframework.cache.ehcache.EhCacheCacheManager">
        <property name="cacheManager" ref="ehcacheManager"/>
        <property name="transactionAware" value="true"/>
    </bean>
</beans>

Third

create new file ehcache.xml

<?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="false">

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

    <defaultCache eternal="false" maxEntriesLocalHeap="1000" overflowToDisk="false" diskPersistent="false" timeToIdleSeconds="3600" timeToLiveSeconds="3600"/>

    <cache name="baseCache" eternal="false" maxEntriesLocalHeap="200" overflowToDisk="false" diskPersistent="false" timeToIdleSeconds="600" statistics="true" timeToLiveSeconds="600"/>

    <!-- eternal="false" // 元素是否永恒,如果是就永不过期(必须设置) maxElementsInMemory="1000" // 缓存容量的内存最大值(必须设置) overflowToDisk="false" // 当缓存达到maxElementsInMemory值是,是否允许溢出到磁盘(必须设置) diskPersistent="false" // 磁盘缓存在VM重新启动时是否保持(默认为false) timeToIdleSeconds="0" // 导致元素过期的访问间隔(秒为单位). 0表示可以永远空闲,默认为0 timeToLiveSeconds="600" // 元素在缓存里存在的时间(秒为单位). 0 表示永远存在不过期 memoryStoreEvictionPolicy="LFU" // 当达到maxElementsInMemory时,如何强制进行驱逐默认使用"最近使用(LRU)"策略,其它还有先入先出FIFO,最少使用LFU,较少使用LRU -->
</ehcache>

Forth

add cache-config.xml to main spring.xml

<import resource="cache-config.xml"/>

or
web.xml

<context-param>
 <param-name>contextConfigLocation</param-name>
  <param-value>classpath*:applicationContext.xml,classpath:cache-config.xml</param-value>
</context-param>

Finally

import org.springframework.cache.annotation.Cacheable;

import java.util.List;

public class UserDao extends BaseDao {

    //这里
    @Cacheable(value = "baseCache")
    public UserTable getUserByDeviceId(String deviceId) {
        if (deviceId != null) {
            List<UserTable> list = (List<UserTable>) getHibernateTemplate()
                    .find("From UserTable u where u.deviceId='" + deviceId
                            + "'");
            if (list != null && list.size() > 0) {
                return list.get(0);
            }
        }
        return null;
    }

}
