## 背景了解 ##

参考阅读  
版本redisson-spring-boot-starter-3.13.6  
RedissonAutoConfiguration初始化源码解析  
https://blog.csdn.net/lizz861109/article/details/109289430

redisson-spring-boot-starter-3.13.6版本之前的老版本是只有config方式，此版本开始增加了file配置方式

@ConfigurationProperties(
        prefix = "spring.redis.redisson"
    )
    public class RedissonProperties { 
        private String config;
        private String file;
    
        public RedissonProperties() { 
        }
    
        public String getConfig() { 
            return this.config;
        }
    
        public void setConfig(String config) { 
            this.config = config;
        }
    }

## 多环境配置redission ##

配置方式有多种  
1.直接使用redission的Properties配置yml  
2.使用spring的redis配置  
3.从配置中心读取配置

### 直接使用redission的Properties配置 ###

redisson-dev.yml  
redisson-test.yml  
redisson-uat.yml

import com.alibaba.cloud.nacos.NacosConfigProperties;
    import com.alibaba.nacos.api.NacosFactory;
    import com.alibaba.nacos.api.PropertyKeyConst;
    import com.alibaba.nacos.api.config.ConfigService;
    import com.alibaba.nacos.api.exception.NacosException;
    import org.redisson.Redisson;
    import org.redisson.api.RedissonClient;
    import org.redisson.config.Config;
    import org.redisson.spring.starter.RedissonProperties;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.cloud.context.config.annotation.RefreshScope;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.core.env.Environment;
    import org.springframework.core.io.ClassPathResource;
    
    import javax.annotation.PostConstruct;
    import java.io.IOException;
    import java.util.Properties;
    
    
    @Configuration
    @RefreshScope
    public class RedissonConfig {
    
        @Autowired
        private Environment env;
    
        @Autowired
        private NacosConfigProperties nacosConfigProperties;
    
    
    
    
    
        @Bean(destroyMethod = "shutdown")
        public RedissonClient redissonClient() throws IOException, NacosException {
            String[] profiles = env.getActiveProfiles();
            String profile = "";
            if(profiles.length > 0) {
                profile = "-" + profiles[0];
            }
    
           Config config = Config.fromYAML(new ClassPathResource("redisson" + profile + ".yml").getInputStream());
            RedissonClient redisson = Redisson.create(config);
            return redisson;
        }
    
    
    }

### 从spring redis中配置 ###

spring redis配置

spring:
      redis:
        cluster:
          nodes: 192.16.32.176:6371,192.16.32.176:6372
        database: 0
        password: password
        maxAttempts: 5
        timeout: 3000
        pool:
          maxActive: 300
          maxIdle: 100
          minIdle: 35
          max-wait: 4000
          maxWaitMillis: 3000
          test-on-borrow: true
          test-while-idle: true

自定义配置类

/** *从spring redis中获取 * redisson 配置类 * @author jerry */
    @Configuration
    public class RedissonConfig implements EnvironmentAware { 
    
      private static final String PREFIX = "redis://";
      private static final String HOST_KEY = "spring.redis.host";
      private static final String PORT_KEY = "spring.redis.port";
      private static final String CLUSTER_KEY = "spring.redis.cluster.nodes";
      private static final String PASSWORD_KEY = "spring.redis.password";
    
      private Environment environment;
    
      @Bean
      public RedissonClient getRedisson() { 
    
        String host = environment.getProperty(HOST_KEY);
        String password = environment.getProperty(PASSWORD_KEY);
        Config config = new Config();
    
        if (!StringUtils.isEmpty(host)) { 
          String port = environment.getProperty(PORT_KEY);
          if (StringUtils.isEmpty(port)) { 
            throw new IllegalArgumentException("[getRedisson] port is null.");
          }
          config.useSingleServer().setAddress(PREFIX + host + ":" + port);
          if (!StringUtils.isEmpty(password)) { 
            config.useSingleServer().setPassword(password);
          }
        } else { 
          String cluster = environment.getProperty(CLUSTER_KEY);
          if (StringUtils.isEmpty(cluster)) { 
            throw new IllegalArgumentException("[getRedisson] cluster is null.");
          }
          String[] nodes = cluster.split(",");
          for (int i = 0; i < nodes.length; i++) { 
            nodes[i] = PREFIX + nodes[i];
          }
          config.useClusterServers().setScanInterval(2000).addNodeAddress(nodes);
          if (!StringUtils.isEmpty(password)) { 
            config.useClusterServers().setPassword(password);
          }
        }
    
        return Redisson.create(config);
      }
    
      @Override
      public void setEnvironment(Environment environment) { 
        this.environment = environment;
      }
    }

### nacos中读取配置 ###

@Autowired
        private RedissonProperties redssionProperties;
    
        @Bean(destroyMethod = "shutdown")
        public RedissonClient redissonClient() throws IOException, NacosException {
    
            Properties properties = new Properties();
            // nacos服务器地址，127.0.0.1:8848
            properties.put(PropertyKeyConst.SERVER_ADDR, nacosConfigProperties.getServerAddr());
            // 配置中心的命名空间id
            properties.put(PropertyKeyConst.NAMESPACE, nacosConfigProperties.getNamespace());
            ConfigService configService = NacosFactory.createConfigService(properties);
            // 根据dataId、group定位到具体配置文件，获取其内容. 方法中的三个参数分别是: dataId, group, 超时时间
            String content = configService.getConfig(redssionProperties.getConfig(), nacosConfigProperties.getGroup(), 3000L);
            // 因为我的配置内容是JSON数组字符串，这里将字符串转为JSON数组
            System.out.println(content);
            Config config = Config.fromYAML(content);
            RedissonClient redisson = Redisson.create(config);
            return redisson;
        }

spring:
    	redis:
        	redisson: redisson.yml

在nacos中增加配置redisson.yml
