使用StringRedisTemplate進行redis連接操作

1，引入jar，需要jar有三個，如下

    <dependency>
        <groupId>org.springframework.data</groupId>
        <artifactId>spring-data-redis</artifactId>
        <version>2.1.4.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.apache.commons</groupId>
        <artifactId>commons-pool2</artifactId>
        <version>2.4.2</version>
    </dependency>
    <!-- https://mvnrepository.com/artifact/redis.clients/jedis -->
    <dependency>
        <groupId>redis.clients</groupId>
        <artifactId>jedis</artifactId>
        <version>2.9.0</version>
    </dependency>

注意spring-data-redis和jedis版本問題，如下圖mavan資源倉庫都會有對應的spring-data-redis支持的jedis版本
2，配置StringRedisTemplate，在redisConfiguration類中，配置redis連接池，下面給出了最簡單的redis測試示例。

 @Bean
    public RedisConnectionFactory redisConnectionFactory() {
        JedisConnectionFactory jedisConnectionFactory = new JedisConnectionFactory();
        jedisConnectionFactory.setHostName("127.0.0.1");
        jedisConnectionFactory.setPort(6379);
        jedisConnectionFactory.setPassword("1234");
       return jedisConnectionFactory;
    }


    @Bean
    public StringRedisTemplate stringRedisTemplate(RedisConnectionFactory redisConnectionFactory) {
        StringRedisTemplate stringRedisTemplate = new StringRedisTemplate();
        stringRedisTemplate.setConnectionFactory(redisConnectionFactory);
        return stringRedisTemplate;
    }

3，具體操作，可以設置如下api

    /**
     * 對hash類型的數據操作
     *
     * @param redisTemplate
     * @return
     */
    @Bean
    public HashOperations<String, String, Object> hashOperations(RedisTemplate<String, Object> redisTemplate) {
        return redisTemplate.opsForHash();
    }

    /**
     * 對redis字符串類型數據操作
     *
     * @param redisTemplate
     * @return
     */
    @Bean
    public ValueOperations<String, Object> valueOperations(RedisTemplate<String, Object> redisTemplate) {
        return redisTemplate.opsForValue();
    }

    /**
     * 對鏈表類型的數據操作
     *
     * @param redisTemplate
     * @return
     */
    @Bean
    public ListOperations<String, Object> listOperations(RedisTemplate<String, Object> redisTemplate) {
        return redisTemplate.opsForList();
    }

    /**
     * 對無序集合類型的數據操作
     *
     * @param redisTemplate
     * @return
     */
    @Bean
    public SetOperations<String, Object> setOperations(RedisTemplate<String, Object> redisTemplate) {
        return redisTemplate.opsForSet();
    }

    /**
     * 對有序集合類型的數據操作
     *
     * @param redisTemplate
     * @return
     */
    @Bean
    public ZSetOperations<String, Object> zSetOperations(RedisTemplate<String, Object> redisTemplate) {
        return redisTemplate.opsForZSet();
    }

測試代碼如下，需要將StringRedisTemplate註冊給我們的業務類：

@Autowired
private StringRedisTemplate redisTemplate;


@PostConstruct
public void init(){
    //操作string
    redisTemplate.opsForValue().set("baomw","XXXsada");

    System.out.println(redisTemplate.opsForValue().get("baomw"));

}

如上圖，就完成了一個簡單的redis操作調用了。
