redis

redis jedis

首先安装redis 不细描述了，我的是安装在ubuntu16.0.4上

然后启动redis cd到redis的安装目录下然后redis.server redis.conf 启动，

之前我在只执行redis.server 的时候好像不行，

记得在redis.conf 配置开启远程访问

启动起来了

测试成功

下面开始我们的redis 跟spring的结合

maven 配置引入

        <dependency>
            <groupId>org.springframework.data</groupId>
            <artifactId>spring-data-redis</artifactId>
            <version>1.7.0.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>redis.clients</groupId>
            <artifactId>jedis</artifactId>
            <version>2.8.0</version>
        </dependency>
        <dependency>
            <groupId>org.apache.commons</groupId>
            <artifactId>commons-pool2</artifactId>

            <scope>provided</scope>
        </dependency>
        <dependency>
            <groupId>org.codehaus.jackson</groupId>

        </dependency>

        <dependency>
            <groupId>org.springframework</groupId>

        </dependency>

        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-log4j12</artifactId>
            <version>1.7.10</version>
        </dependency>

jar包

spring-redis 文件配置

    <!--         <bean id="cacheManager" class="org.springframework.data.redis.cache.RedisCacheManager" c:template-ref="redisTemplate"/> -->

</beans>

然后就是service中的应用

  @Resource(name="redisTemplate")
     RedisTemplate redisTemplate;

@Override
    public User getUser(final String id) {
        ValueOperations<String, User> valueops = redisTemplate
                     .opsForValue();
              User user = valueops.get(id);
              return user;
    }


 @Override
    public void saveUser( User user) {
      // redisTemplate.opsForValue().set("guo", "ok");
//        redisTemplate.execute(new RedisCallback<Object>() {
//
//            @Override
//            public Object doInRedis(RedisConnection connection) throws DataAccessException {
//                connection.set(redisTemplate.getStringSerializer().serialize("user.uid." + user.getUserid()),
//                        redisTemplate.getStringSerializer().serialize(user.getProfilephoto()));
//                return null;
//            }
//        });
//        ValueOperations<String, User> valueops = redisTemplate.opsForValue();
        ValueOperations<String, User> valueops = redisTemplate.opsForValue();
        valueops.set(user.getUserid(), user);

    }

对list的存储

    @Override
    public void saveUserList() {
        // redisTemplate.opsForValue().set("guo", "ok");
//        redisTemplate.execute(new RedisCallback<Object>() {
//
//            @Override
//            public Object doInRedis(RedisConnection connection) throws DataAccessException {
//                connection.set(redisTemplate.getStringSerializer().serialize("user.uid." + user.getUserid()),
//                        redisTemplate.getStringSerializer().serialize(user.getProfilephoto()));
//                return null;
//            }
//        });
//        ValueOperations<String, User> valueops = redisTemplate.opsForValue();
        List<User> list=new ArrayList<User>();
        for(int i=0;i<=5;i++){
            User user=new User();
            user.setUserid(""+i);
            list.add(user);
        }
        ListOperations<String, List> valueops = redisTemplate.opsForList();
        valueops.leftPush("list",list);

    }




  @Override
    public List<User> getUserList() {
        // redisTemplate.opsForValue().set("guo", "ok");
//        redisTemplate.execute(new RedisCallback<Object>() {
//
//            @Override
//            public Object doInRedis(RedisConnection connection) throws DataAccessException {
//                connection.set(redisTemplate.getStringSerializer().serialize("user.uid." + user.getUserid()),
//                        redisTemplate.getStringSerializer().serialize(user.getProfilephoto()));
//                return null;
//            }
//        });
//        ValueOperations<String, User> valueops = redisTemplate.opsForValue();


        ListOperations<String, List> valueops = redisTemplate.opsForList();
         List<User> list= valueops.leftPop("list");
         return list;

    }

redis.opsForValue() 封装操作strings

redis.opsForList() 封装操作list

redis.opsForSet() 封装操作sets

redis.opsForZSet() 封装操作sorted sets

redis.opsForHash() 封装操作hashs

其他的在实际运用中再补充
