基于Redis的Method缓存公用jar

使用

添加Jar依赖

<dependency>
     <groupId>com.whosenet</groupId>
     <artifactId>redis-cache</artifactId>
      <version>1.0</version>
</dependency>

Spring配置

<bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
    <property name="maxTotal" value="50" ></property>
    <property name="maxIdle" value="10" ></property>
    <property name="maxWaitMillis" value="1000" ></property>
    <property name="testOnBorrow" value="true" ></property>
</bean>
<bean id="jedisPool" class="redis.clients.jedis.JedisPool">
    <constructor-arg index="0" ref="jedisPoolConfig" ></constructor-arg>
    <constructor-arg index="1" value="127.0.0.1" ></constructor-arg>
    <constructor-arg index="2" value="6379" ></constructor-arg>
</bean>

使用方式

• 添加缓存
  • key:缓存集合名
  • fieldKey:缓存key,支持SPEL表达式

   @Transactional
   @Cacheable(key="getAdminByName",fieldKey="#name")
   public Admin getByName(String name) {
       return adminDao.getByUsername(name);
   }

• 清理缓存
  • key:缓存集合名
  • fieldKey:缓存key,支持SPEL表达式
  • allEntries:是否清除该集合下所有key的缓存(默认false)

   @Transactional
   @CacheEvict(key="getAdminByName",fieldKey="#admin.username")
   public void update(Admin admin){
       adminDao.update(admin);
   }
