异步 mongodb 客户端 vert.x 出错

Question

我使用此代码连接到本地主机 mongodb 数据库。连接后，当我想检索数据时出现此异常。

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";
            }

        });

Mongodb 下面的配置包含 db_name 、端口、主机和我需要连接到数据库的更多选项。这些选项对 mongodb 同步客户端（我使用之前）。

"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
  }

我认为您的 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 出错

error on async mongodb client vert.x
