redis Demo 完美代码

redis配置

#redis配置
#redis.host=47.98.210.68
redis.host=localhost
redis.port=6379
redis.timeout=10
redis.password=123456
redis.poolMaxTotal=1000
redis.poolMaxIdle=500
redis.poolMaxWait=500

config配置

@Component
@ConfigurationProperties(prefix = "redis")  // 读取配置文件 前缀是redis
public class RedisConfig {
    private String host;
    private int port;
    private int timeout;    // 秒
    private String password;
    private int poolMaxTotal;
    private int poolMaxIdle;
    private int poolMaxWait; // 秒

    public String getHost() {
        return host;
    }

    public void setHost(String host) {
        this.host = host;
    }

    public int getPort() {
        return port;
    }

    public void setPort(int port) {
        this.port = port;
    }

    public int getTimeout() {
        return timeout;
    }

    public void setTimeout(int timeout) {
        this.timeout = timeout;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public int getPoolMaxTotal() {
        return poolMaxTotal;
    }

    public void setPoolMaxTotal(int poolMaxTotal) {
        this.poolMaxTotal = poolMaxTotal;
    }

    public int getPoolMaxIdle() {
        return poolMaxIdle;
    }

    public void setPoolMaxIdle(int poolMaxIdle) {
        this.poolMaxIdle = poolMaxIdle;
    }

    public int getPoolMaxWait() {
        return poolMaxWait;
    }

    public void setPoolMaxWait(int poolMaxWait) {
        this.poolMaxWait = poolMaxWait;
    }
}

获取JedisPool（ redis.clients.jedis;）

@Service
public class RedisPoolFactory {

    @Autowired
    RedisConfig redisConfig;

    @Bean   // 将这个bean注入到/加载到 Spring容器里
    public JedisPool jedisPoolFactory() {
        JedisPoolConfig poolConfig = new JedisPoolConfig();
        poolConfig.setMaxIdle(redisConfig.getPoolMaxIdle());
        poolConfig.setMaxTotal(redisConfig.getPoolMaxTotal());
        poolConfig.setMaxWaitMillis(redisConfig.getPoolMaxWait() * 1000);

        JedisPool jedisPool = new JedisPool(poolConfig,redisConfig.getHost(),
                redisConfig.getPort(),redisConfig.getTimeout()*1000,
                redisConfig.getPassword(),0);
        return jedisPool;
    }
}

    @Autowired
    JedisPool jedisPool;

	 Jedis jedis = jedisPool.getResource();
	 Jedis类就是对redis缓存操作的工具类了，剩下的就是封装调用，比较简单；
