晚上在网上搞了个例子，
spring-ehcache.xml:
<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"
xmlns:p="http://www.springframework.org/schema/p"
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">
<!-- 缓存 属性-->
<bean id="cacheManagerFactory" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean">
<property name="configLocation" value="classpath:ehcache.xml"/>
</bean>
<!-- 支持缓存注解 -->
<cache:annotation-driven cache-manager="cacheManager" proxy-target-class="true"/>
<!-- 默认是cacheManager -->
<bean id="cacheManager" class="org.springframework.cache.ehcache.EhCacheCacheManager">
<property name="cacheManager" ref="cacheManagerFactory"/>
</bean>
</beans>
ehcache.xml
<?xml version="1.0" encoding="UTF-8"?>
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="ehcache.xsd" updateCheck="true">
<!-- <diskStore path="java.io.tmpdir" /> -->
<diskStore path="D:/cachetmpdir" />
<cache name="message"
maxElementsInMemory="100"
eternal="false"
timeToIdleSeconds="120"
timeToLiveSeconds="120"
overflowToDisk="true"
maxElementsOnDisk="10000000"
diskPersistent="false"
diskExpiryThreadIntervalSeconds="120"
memoryStoreEvictionPolicy="LRU"/>
</ehcache>
service.java
@CachePut(value = "user")
public User save(User user) {
userDao.save(user);
return user;
}
@Cacheable(value = "user", key = "#id")
public String findById(String id) {
return userDao.findById(id);
}
其他的都不是重要的。之前保存什么都可以了的，现在只是想使用一下spring cache
错误信息：
java.lang.IllegalArgumentException: Cannot find cache named 'user' for CacheableOperation[public java.lang.String com.bob.module.contract.service.impl.UserServiceImpl.findById(java.lang.String)] caches=[userServiceImpl] | key='#id' | condition='' | unless=''

请教大神了～～～～到底怎么解决这个问题
------解决思路----------------------
<cache name="message"这里定义的什么名字，使用的时候还用什么名字。
------解决思路----------------------
因为你在 spring-ehcache.xml: 设置 了这个 name="message" 所以名称应该是 message
------解决思路----------------------
上楼说错了。 你是在 ehcache.xml 设置 了这个 name="message" 所以名称应该是 message
