程序运行卡住排查

背景

在写spring ai的时候添加了一些依赖后程序在这卡住了，没有任何报错

bash 复制代码

排查

第一步：是问AI得到 jcmd 73805 Thread.print 看了线程栈，main 线程停在
io.qdrant.client.grpc.QdrantGrpcClient$Builder.checkVersionsCompatibility()

第二步：从运行改为debug，搜索代码找到QdrantGrpcClient，发现这里报错了，是qdrant版本不对

java 复制代码

private void checkVersionsCompatibility(String clientVersion) {
   try {
     String serverVersion =
         QdrantGrpc.newBlockingStub(this.channel)
             .healthCheck(QdrantOuterClass.HealthCheckRequest.getDefaultInstance())
             .getVersion();
     if (!VersionsCompatibilityChecker.isCompatible(clientVersion, serverVersion)) {
       String logMessage =
           "Qdrant client version "
               + clientVersion
               + " is incompatible with server version "
               + serverVersion
               + ". Major versions should match and minor version difference must not exceed 1. "
               + "Set checkCompatibility=false to skip version check.";
       logger.warn(logMessage);
     }
   } catch (Exception e) {
     logger.warn(
         "Failed to obtain server version. Unable to check client-server compatibility. Set checkCompatibility=false to skip version check.");
   }
 }

第三步：修改版本成功运行

复盘

1.程序卡住用debug模式能看到WARN，在运行模式下可能看不到报错日志

2.利用jcmd命令找到线程栈，明确卡在哪里，一开始问AI一直以为是TransformersEmbeddingModel的问题，看了才发现是VectorStore的问题
