MongoDB Java插入抛出找不到org.variabel.bsonDocument类的编解码器

Question

import java.util.Map;
import org.bson.Document;
public class BsonDocument extends Document{
    public BsonDocument() {
        super();
    }

    public BsonDocument(Map<String, Object> map) {
        super(map);
    }

    public BsonDocument(String key, Object value){
        super(key, value);
    }
}

MongoClient mongoClient = new MongoClient( "localhost" , 27017 );
// Now connect to your databases
MongoDatabase db = mongoClient.getDatabase("tes123");

BsonDocument document = new BsonDocument();

document.put("name", "Sony");
document.put("age", 30);
document.put("createdDate", new Date());
db.getCollection("tes123").insertOne(document);

我试过你的代码，只修改了一行，结果是正确的。这是我的版本

import com.mongodb.MongoClient;
import com.mongodb.client.MongoDatabase;

import java.util.Date;

/**
 * @author Hanz
 * @date 2019/8/22
 */
public class testDocument {
    public static void main(String[] args){
        MongoClient mongoClient = new MongoClient("127.0.0.1",27017);   // i changed this 'localhost' to '127.0.0.1'
        MongoDatabase db = mongoClient.getDatabase("test");

        BsonDocument document = new BsonDocument();
        document.put("name", "Sony");
        document.put("age", 30);
        document.put("createdDate", new Date());
        db.getCollection("tes123").insertOne(document);
    }

}

另一个文件和你的一样，但以防万一，这是我的代码

import org.bson.Document;
import java.util.Map;
/**
 * @author Hanz
 * @date 2019/8/22
 */
public class BsonDocument extends Document {

    public BsonDocument() {
        super();
    }

    public BsonDocument(Map<String, Object> map) {
        super(map);
    }

    public BsonDocument(String key, Object value){
        super(key, value);
    }
}

您是否检查了您的mongo数据库，看看它是否有数据库“test123”？希望您解决了这个问题或者这个答案可以帮助您：）
