spring.redis.timeout=-1

五、SpringBoot整合Jedis

1、编写application.properties配置文件

#redis连接地址
spring.redis.host=127.0.0.1
#redis连接端口
spring.redis.port=6379
#redis使用第几个数据库
spring.redis.database=3
#redis连接超时时间
spring.redis.timeout=1800000
#redis密码
spring.redis.password=
# 连接池最大连接数（使用负值表示没有限制）
spring.redis.jedis.pool.max-active=20
# 连接池最大阻塞等待时间（使用负值表示没有限制）
spring.redis.jedis.pool.max-wait=-1
# 连接池中的最大空闲连接
spring.redis.jedis.pool.max-idle=5
# 连接池中的最小空闲连接
spring.redis.jedis.pool.min-idle=0

2、编写配置类

@Configuration
public class RedisConfig {

    @Value("${spring.redis.host}")
    private String host;
    @Value("${spring.redis.port}")
    private int port;
    @Value("${spring.redis.timeout}")
    private int timeout;
    @Value("${spring.redis.password}")
    private String password;
    @Value("${spring.redis.database}")
    private int database;
    @Value("${spring.redis.jedis.pool.max-active}")
    private int maxActive;
    @Value("${spring.redis.jedis.pool.max-idle}")
    private int maxIdle;
    @Value("${spring.redis.jedis.pool.min-idle}")
    private int minIdle;
    @Value("${spring.redis.jedis.pool.max-wait}")
    private long maxWaitMillis;

    @Bean
    public JedisPool redisPoolFactory(){
        JedisPoolConfig jedisPoolConfig = new JedisPoolConfig();
        jedisPoolConfig.setMaxIdle(maxIdle);
        jedisPoolConfig.setMaxWaitMillis(maxWaitMillis);
        jedisPoolConfig.setMaxTotal(maxActive);
        jedisPoolConfig.setMinIdle(minIdle);
        if(password==null || "".equals(password.trim())) {
            password=null;
        }
        JedisPool jedisPool = new JedisPool(jedisPoolConfig,host,port,timeout,password,database);
        return jedisPool;
    }
}

3、测试

@SpringBootTest
class RedisDemoApplicationTests {

    @Autowired
    private JedisPool jedisPool;

    @Test
    void jedisTest() {
        Jedis jedis = jedisPool.getResource();
        String pong = jedis.ping();
        System.out.println("连接成功：" + pong);
        jedis.close();
    }

}

4、相关类型常用Api

与Redis命令行操作一样

Key

@Test
public void keyTest(){
    Jedis jedis = jedisPool.getResource();
    jedis.set("k1","v1");
    jedis.set("k2","v2");
    jedis.set("k3","v3");
    Set<String> keys = jedis.keys("*");
    System.out.println(keys.size());
    for (String key : keys) {
        System.out.println(key);
    }
    System.out.println(jedis.exists("k1"));
    System.out.println(jedis.ttl("k1"));
    System.out.println(jedis.get("k1"));
    jedis.close();
}

    jedis.close();

    map.put("age", "12");

    jedis.hmset("user1",map);
    List<String> users = jedis.hmget("user1", "name", "sex", "age");
    for (String user : users) {
        System.out.println(user);
    }
    jedis.close();

    for (String value : mySet) {
        System.out.print(value + " ");
    }
    System.out.println("");
    System.out.println("===========");
    jedis.srem("mySet","v3");
    Set<String> mySet1 = jedis.smembers("mySet");

    Set<Tuple> myZSet = jedis.zrangeWithScores("myZSet", 0, -1);
    for (Tuple tuple : myZSet) {
        System.out.println(tuple.getElement() + "--->" + tuple.getScore());
    }
