[redisson]redisson-spring-boot-starter 对spring cloud config 支持不友好

自己定义就行啊，比如yaml的时候， redisson.config: | redisson config xxxxxx


    @Value("${redission.config:#{null}}")
    private String redissonConfig;

    @Bean(destroyMethod = "shutdown")
    public RedissonClient redisson() throws IOException {
        Assert.notNull(redissonConfig, "redisson配置无效");
        return Redisson.create(Config.fromYAML(redissonConfig));
    }

我的意思是redisson.yml需要存储在本地。还需要分环境存xx-dev,xx-test.这个对于配置中心这种不太友好。我必须把我的账号密码存储在项目中

哦，明白你的意思了，确实，用redisson-spring-boot-starter还真不如，在SC config 或者SCA nacos里，自己定义一个redisson的配置文件，然后用我的方式


    @Value("${redission.config:#{null}}")
    private String redissonConfig;

    @Bean(destroyMethod = "shutdown")
    public RedissonClient redisson() throws IOException {
        Assert.notNull(redissonConfig, "redisson配置无效");
        return Redisson.create(Config.fromYAML(redissonConfig));
    }

嗯嗯，所以我觉得既然是redisson-spring-boot-starter，那为什么不更靠近spring的标准呢

我目前还是Spring boot-data-starter-data-redis的链接方式，就是配置spring.redis.cluster.nodes这种。也想转到redisson上，但是也有需要根据不同环境配置不同yaml文件的疑问

redisson-spring-boot-starter的意义是支持SpringBoot，Spring Cloud Config Server的配置方式目前还没有正式支持。

Redisson提供的是一套工具，它可以在不依赖其他框架的情况下独立使用。同时在这套工具的基础上，根据不同的框架提供相关的支持，但不会受限于其中。采用外部配置文件的方式允许在不修改代码的情况下，在测试，整合和生产等持续交付的环节中适应不同的Redis环境。这样的设计，允许各个开发人员有不同配置的Redis测试环境，同时还能有效地与生产环境隔离开。通常情况下开发人员的配置文件无需提交代码仓库里，避免了泄漏密码等安全问题。

在配置文件中新增加的变量解析功能或许对这个问题有帮助。 https://github.com/redisson/redisson/issues/2086#issuecomment-488672200

关于题主的问题，我这有一个解决方案：

以singleServerConfig为例，按如下流程：

把yaml里的配置，挪到远程的yml配置中：

//注意这里，把配置放到redisson下
redisson:
singleServerConfig:
idleConnectionTimeout: 10000
pingTimeout: 1000
connectTimeout: 10000
timeout: 3000
retryAttempts: 3
retryInterval: 1500
reconnectionTimeout: 3000
failedAttempts: 3
password: xxxx
subscriptionsPerConnection: 5
clientName: null
address: "redis://192.168.1.2:6379"
subscriptionConnectionMinimumIdleSize: 1
subscriptionConnectionPoolSize: 50
connectionMinimumIdleSize: 32
connectionPoolSize: 64
database: 0
dnsMonitoring: false
dnsMonitoringInterval: 5000
threads: 0
nettyThreads: 0
//注意这里和原配置略有不同
codec:
_class: org.redisson.codec.JsonJacksonCodec     
transportMode: NIO

新建如下类结构：

Properties.class

@Component
@ConfigurationProperties(prefix = "redisson")
@Data
public class Properties {
    @JsonProperty
    SingleServerConfig singleServerConfig;
    int threads;
    int nettyThreads;
    String transportMode;
    Codec codec;
}

Codec.class

@Data
public class Codec{
    @JsonProperty(value = "class")
    String _class;
}

BaseConfig.class

@Data
public class BaseConfig<T extends org.redisson.config.BaseConfig<T>> {

    private static final Logger log = LoggerFactory.getLogger("config");

    /**
     * If pooled connection not used for a <code>timeout</code> time
     * and current connections amount bigger than minimum idle connections pool size,
     * then it will closed and removed from pool.
     * Value in milliseconds.
     */
    private int idleConnectionTimeout = 10000;

    /**
     * Timeout during connecting to any Redis server.
     * Value in milliseconds.
     */
    private int connectTimeout = 10000;

    /**
     * Redis server response timeout. Starts to countdown when Redis command was succesfully sent.
     * Value in milliseconds.
     */
    private int timeout = 3000;

    private int retryAttempts = 3;

    private int retryInterval = 1500;

    /**
     * Password for Redis authentication. Should be null if not needed
     */
    private String password;

    private String username;

    /**
     * Subscriptions per Redis connection limit
     */
    private int subscriptionsPerConnection = 5;

    /**
     * Name of client connection
     */
    private String clientName;

    private boolean sslEnableEndpointIdentification = true;

    private SslProvider sslProvider = SslProvider.JDK;

    private URL sslTruststore;

    private String sslTruststorePassword;

    private URL sslKeystore;

    private String sslKeystorePassword;

    private int pingConnectionInterval;

    private boolean keepAlive;

    private boolean tcpNoDelay;
}

SingleServerConfig.class

@Data
public class SingleServerConfig extends BaseConfig{
    /**
     * Redis server address
     *
     */
    private String address;

    /**
     * Minimum idle subscription connection amount
     */
    private int subscriptionConnectionMinimumIdleSize = 1;

    /**
     * Redis subscription connection maximum pool size
     *
     */
    private int subscriptionConnectionPoolSize = 50;

    /**
     * Minimum idle Redis connection amount
     */
    private int connectionMinimumIdleSize = 24;

    /**
     * Redis connection maximum pool size
     */
    private int connectionPoolSize = 64;

    /**
     * Database index used for Redis connection
     */
    private int database = 0;

    /**
     * Interval in milliseconds to check DNS
     */
    private long dnsMonitoringInterval = 5000;
}

RedissonConfiguration.class

@Configuration
@ComponentScan
@EnableCaching
public  class RedissonConfiguration {
    @Bean(destroyMethod="shutdown")
    RedissonClient redisson(Properties properties) throws IOException {
        ObjectMapper mapper=new ObjectMapper();
        String jsonString = mapper.writeValueAsString(properties);
        Config config = Config.fromJSON(jsonString);
        RedissonClient redisson = Redisson.create(config);
        return redisson;
    }
}

PS : BaseConfig.class、SingleServerConfig.class以及其他子类的属性，可以直接从源码中同名类复制，比较省事，另：如果你有多套配置的需求，你可以找到相应的配置类，如同建立SingleServerConfig一样建立其他的配置类，多个ServerConfig配置类可以同时存在，不会冲突的

这样，就把配置改为了从yml中读取，可以从配置中心拉取，避开了必须配置文件路径的问题，从而实现兼容远程配置的问题。

add config in your yml file on nacos or consul

redisson:
