SpringBoot2以後，默認採用Lettuce做爲redis的鏈接客戶端，固然咱們仍是能夠強制撿回來，使用咱們熟悉的Jedis的，本篇簡單介紹下使用Jedis的相關配置git

I. 基本配置

1. 依賴

使用Jedis與Lettuce不一樣的是，須要額外的引入Jedis包的依賴redis

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-redis</artifactId>
    </dependency>

    <dependency>
        <groupId>org.apache.commons</groupId>
        <artifactId>commons-pool2</artifactId>
    </dependency>

    <dependency>
        <groupId>redis.clients</groupId>
        <artifactId>jedis</artifactId>
    </dependency>
</dependencies>

2. 配置

redis的相關配置，和前面的差很少，只是線程池的參數稍稍有點區別spring

spring:
 redis:
 host: 127.0.0.1
 port: 6379
 password:
 database: 0
 jedis:
 pool:
 max-idle: 6
 max-active: 32
 max-wait: 100
 min-idle: 4

3. AutoConfig

與前面不一樣的是，咱們須要定義一個RedisConnectionFactory的bean做爲默認的鏈接工廠，以此來肯定底層的鏈接採用的是Jedis客戶端apache

@Configuration
public class RedisAutoConfig {

    @Bean
    public RedisConnectionFactory redisConnectionFactory(JedisPoolConfig jedisPool, RedisStandaloneConfiguration jedisConfig) {
        JedisConnectionFactory connectionFactory = new JedisConnectionFactory(jedisConfig);
        connectionFactory.setPoolConfig(jedisPool);
        return connectionFactory;
    }

    @Configuration
    public static class JedisConf {
        @Value("${spring.redis.host:127.0.0.1}")
        private String host;
        @Value("${spring.redis.port:6379}")
        private Integer port;
        @Value("${spring.redis.password:}")
        private String password;
        @Value("${spring.redis.database:0}")
        private Integer database;

        @Value("${spring.redis.jedis.pool.max-active:8}")
        private Integer maxActive;
        @Value("${spring.redis.jedis.pool.max-idle:8}")
        private Integer maxIdle;
        @Value("${spring.redis.jedis.pool.max-wait:-1}")
        private Long maxWait;
        @Value("${spring.redis.jedis.pool.min-idle:0}")
        private Integer minIdle;

        @Bean
        public JedisPoolConfig jedisPool() {
            JedisPoolConfig jedisPoolConfig = new JedisPoolConfig();
            jedisPoolConfig.setMaxIdle(maxIdle);
            jedisPoolConfig.setMaxWaitMillis(maxWait);
            jedisPoolConfig.setMaxTotal(maxActive);
            jedisPoolConfig.setMinIdle(minIdle);
            return jedisPoolConfig;
        }

        @Bean
        public RedisStandaloneConfiguration jedisConfig() {
            RedisStandaloneConfiguration config = new RedisStandaloneConfiguration();
            config.setHostName(host);
            config.setPort(port);
            config.setDatabase(database);
            config.setPassword(RedisPassword.of(password));
            return config;
        }
    }
}
