缓存，spring

applicationcontext.xml

xmlns:cache="http://www.springframework.org/schema/cache"

xsi:schemaLocation=http://www.springframework.org/schema/cache http://www.springframework.org/schema/cache/spring-cache-3.1.xsd

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

<bean id="cache" class="org.springframework.cache.support.SimpleCacheManager">
        <property name="caches">
            <list>
                <bean class="org.springframework.cache.concurrent.ConcurrentMapCacheFactoryBean"  p:name="qus"></bean>
                <bean class="org.springframework.cache.concurrent.ConcurrentMapCacheFactoryBean"  p:name="clo"></bean>
            </list>
        </property>
    </bean>

业务层

方法上面实现@Cacheable("clo")

例如：

@Cacheable("clo")
    public List<Clothingcategory> cFindAll() {
        return clothingcategoryDAO.findAll();
    }

切记：clo是在bean在配置的，请看上面
