Question

我使用此代码连接到localhost mongodb数据库。连接后，当我想要检索数据时，我得到了这个例外。

SEVERE: com.mongodb.internal.async.ErrorHandlingResultCallback.errorHandlingCallback(Lcom/mongodb/async/SingleResultCallback;)Lcom/mongodb/async/SingleResultCallback;
java.lang.NoSuchMethodError: com.mongodb.internal.async.ErrorHandlingResultCallback.errorHandlingCallback(Lcom/mongodb/async/SingleResultCallback;)Lcom/mongodb/async/SingleResultCallback;

我的代码：

MongoClient mongoClient = MongoClient.createShared(vertx, config().getJsonObject("mongodb"));
        mongoClient.find("user",new JsonObject(),res->{
            if (res.succeeded()){
                List<JsonObject> jsonObjects=res.result();
                String name="ali";
                LOGGER.warn(jsonObjects.toString());
            }
            else{
                String name="name";
            }

        });

下面的Mongodb配置包含db_name，端口，主机和我需要连接到数据库的更多选项。这些选项适用于mongodb同步客户端（我之前使用过）。

"mongodb": {
    "host" : "127.0.0.1",
    "port" : 27017,
    "db_name":"amibackend",
    "maxPoolSize" : 50,
    "minPoolSize" : 25,
    "maxIdleTimeMS" : 300000,
    "maxLifeTimeMS" : 3600000,
    "waitQueueMultiple"  : 10,
    "waitQueueTimeoutMS" : 10000,
    "maintenanceFrequencyMS" : 2000,
    "maintenanceInitialDelayMS" : 500
  }

我认为你的mongodb驱动程序版本有问题。我建议您升级mongodb驱动程序。

current version of ErrorHandlingResultCallback.java

history version of ErrorHandlingResultCallback.java

异步mongodb客户端vert.x
