Spring @Cacheable guava cache

一、XML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"
       xmlns:context="http://www.springframework.org/schema/context"
       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/context
    http://www.springframework.org/schema/context/spring-context.xsd
    http://www.springframework.org/schema/cache
    http://www.springframework.org/schema/cache/spring-cache-3.2.xsd">

    <context:annotation-config/>

    <!--缓存 20秒过期 初始化容量100-->
    <cache:annotation-driven/>
    <bean id="cacheManager" class="org.springframework.cache.guava.GuavaCacheManager">
        <property name="cacheSpecification" value="expireAfterWrite=20s,initialCapacity=100"/>
    </bean>
</beans> 

二、使用

说明：p0代表第一个参数，后面的为参数属性。如果第二次请求的参数中的三个属性与上一次相同，那么就会被缓存(在有效期内)

    @RequestMapping(value = "/query/hisen", method = RequestMethod.GET)
    @ResponseBody
    @Cacheable(value = "hisen", key = "#p0.name + #p0.age + #p0.gender")
    public ResultBean<List<QueryRes>> queryHisen(@ModelAttribute QueryReq req) {
        //someThing
    }

三、key的用法
