Spring Boot Native + Redis启动报错：无法创建RedisConnection Bean

正在构建名为systemparam的Spring Boot 3.1 Native应用，采用Gradle构建、Lettuce作为Redis连接工厂、GraalVM CE Java17-22.3.2作为编译环境。应用通过标准编译可正常运行，但经Native编译后，启动时抛出UnsatisfiedDependencyException，提示无法创建cacheManager及redisConnection Bean，根源为Netty DNS解析相关的NullPointerException。已尝试添加io.lettuce:lettuce-core:6.2.4.RELEASE依赖，但问题未解决。

解决方案 #

• 自定义Lettuce客户端资源，规避DNS JNDI解析
  创建Redis配置类，显式指定DNS解析方式，避免Netty自动加载系统DNS配置时触发NPE：

  @Configuration
  public class RedisConfig {
      @Bean
      public LettuceClientResources lettuceClientResources() {
          return DefaultClientResources.builder()
                  .dnsAddressResolverGroup(DnsAddressResolverGroup.newBuilder()
                          .nameResolver(DnsNameResolverBuilder.newInstance()
                                  .serverAddresses(DefaultDnsServerAddressStreamProvider.INSTANCE)
                                  .build())
                          .build())
                  .build();
      }
  
      @Bean
      public LettuceConnectionFactory lettuceConnectionFactory(LettuceClientResources clientResources) {
          LettuceConnectionFactory factory = new LettuceConnectionFactory();
          factory.setClientResources(clientResources);
          return factory;
      }
  }
  

• 添加GraalVM编译参数，启用安全服务
  在build.gradle中配置Native镜像构建参数，确保必要的系统服务可用：

  graalvmNative {
      binaries {
          main {
              buildArgs.add("--enable-all-security-services")
          }
      }
  }
  

• 升级依赖版本
  升级Spring Boot到3.1.5及以上，或Lettuce到6.2.6及以上，这些版本修复了Native环境下的DNS解析兼容性问题。

• 直接使用Redis IP地址
  将Redis配置中的域名替换为IP地址，彻底绕过DNS解析流程，消除NPE触发点。
