springboot项目中 jedis对redis缓存的操作

1:导入依赖

<!--jedis-->
<dependency>
    <groupId>redis.clients</groupId>
    <artifactId>jedis</artifactId>
    <version>2.5.2</version>
</dependency>

2：配置文件

# Jedis
jedis.max.total = 100
jedis.max.idle = 10
jedis.max.waitmillis = 10000
jedis.testOnBorrow = true
jedis.max.timeout = 10000
jedis.host = localhost

3：实例bean

@Configuration
public class JedisConfig {

    Logger logger = LoggerFactory.getLogger( JedisConfig.class );

     */
    @Value( "${jedis.port}" )
    private Integer port;


    /**
     * local
     */
    @Value( "${jedis.host}" )
    private String host;


    /**

     */
    @Value( "${jedis.max.timeout}" )
    private Integer timeout;






    @Bean
    public JedisPoolConfig getRedisConfig() {
        JedisPoolConfig poolConfig = new JedisPoolConfig();
        return poolConfig;
    }




    @Bean
    public JedisPool getJedisPool() {
        JedisPoolConfig config = getRedisConfig();
        JedisPool pool = new JedisPool(config,host,port,timeout);
        logger.info("init JredisPool ...");
        return pool;
    }



    @Bean
    public Jedis getJedis() {
        return getJedisPool().getResource();
    }
