Question

当我将Redis与springboot2.x集成时，我遇到了两个相互交织的问题：

使用yml文件时，无法读取redis的密码。
改为使用属性文件读取密码，但会显示异常。

在这里我简要地解释一下，DefaultJedisClientConfiguration是JedisClientConfiguration的实现类，而MutableJedisClientConfiguration也是实现类，作为JedisConnectionFactory中的静态内部类。 / p>

为什么要调用setTimeout()中不赞成使用的方法JedisConnectionFactory？此外，当我使用.yml文件配置redis资源时，没有这样的错误，即不会调用该函数，而当使用.properties文件时，它将被调用

/** @deprecated */
@Deprecated
public void setTimeout(int timeout) {
    this.getMutableConfiguration().setReadTimeout(Duration.ofMillis((long)timeout));
    this.getMutableConfiguration().setConnectTimeout(Duration.ofMillis((long)timeout));
}

//现在，将执行Assert.state（）。

private JedisConnectionFactory.MutableJedisClientConfiguration getMutableConfiguration() {
    Assert.state(this.clientConfiguration instanceof JedisConnectionFactory.MutableJedisClientConfiguration, () -> {
        return String.format("Client configuration must be instance of MutableJedisClientConfiguration but is %s", new Object[]{ClassUtils.getShortName(this.clientConfiguration.getClass())});
    });
    return (JedisConnectionFactory.MutableJedisClientConfiguration)this.clientConfiguration;
}

当我们传递poolConfig时，JedisConnectionFactory将生成MutableJedisClientConfiguration，但是当我们自己构建JedisClientConfiguration时，它就是生成的DefaultJedisClientConfiguration

我的配置Java代码：

@Configuration
@PropertySource("classpath:config/redis.yml") // .yml
@EnableAutoConfiguration
class RedisConfig {

    @Value("${spring.redis.password:123456}") // can not read password, should set default value
    private String password;


    @Bean
    @ConfigurationProperties(prefix="spring.redis.pool")
    public JedisPoolConfig jedisPoolConfig(){
        return new JedisPoolConfig();
    }

    @Bean
    @ConfigurationProperties(prefix="spring.redis")
    public JedisConnectionFactory jedisConnectionFactory(){
        RedisStandaloneConfiguration redisStandaloneConfiguration = new RedisStandaloneConfiguration();
        redisStandaloneConfiguration.setPassword(RedisPassword.of(password));

        JedisConnectionFactory jedisConnectionFactory = null;

        JedisClientConfiguration.JedisClientConfigurationBuilder jedisClientConfiguration = JedisClientConfiguration.builder();

        jedisConnectionFactory =  new JedisConnectionFactory(redisStandaloneConfiguration,
                jedisClientConfiguration.build()); // build() -> DefaultJedisClientConfiguration

        return jedisConnectionFactory;
    }
}

我的属性文件：

spring.redis.host=localhost
spring.redis.port=6379
spring.redis.name=localhost_redis
spring.redis.timeout=5000
spring.redis.password=123456
spring.redis.minIdle=1
spring.redis.maxTotal=5000
spring.redis.numTestsPerEvictionRun=100
spring.redis.timeBetweenEvictionRunsMillis=6000
spring.redis.testWhileIdle=true
spring.redis.testOnBorrow=true
spring.redis.testOnReturn=true
spring.redis.pool.max-idle=10
spring.redis.pool.max-wait=5000

yml文件：

spring:
  redis:
    dbIndex: 0
    hostName: localhost
    password: 123456
    port: 6379
    timeout: 5000
    pool:
      maxIdle: 8
      minIdle: 0
      maxActive: 8
      maxWait: -1

错误：

Description:

Failed to bind properties under 'spring.redis' to org.springframework.data.redis.connection.jedis.JedisConnectionFactory:

    Property: spring.redis.timeout
    Value: 5000
    Origin: "spring.redis.timeout" from property source "class path resource [config/redis.properties]"
    Reason: Client configuration must be instance of MutableJedisClientConfiguration but is DefaultJedisClientConfiguration

Action:

Update your application's configuration

如何处理异常“客户端配置必须是MutableJedisClientConfiguration的实例，但必须是DefaultJedisClientConfiguration”
