Question

我正在尝试进行无序批量插入，但是我收到了写入错误，并且在同一个插件上工作。

    final DBCollection col = db.getCollection(STUDENT);
    BulkWriteOperation bulkop = col.initializeUnorderedBulkOperation();

    for(){
    //putting values in doc
    DBObject doc = new BasicDBObject();
    //
    bulkop.insert(doc);
    }
        bulkop.execute(WriteConcern.FSYNCED);

这是log：

Bulk write operation error on server IP:27017. Write errors: [com.mongodb.BulkWriteError@24cd7085]. 
com.mongodb.BulkWriteException: Bulk write operation error on server 192.168.50.166:27017. Write errors: [com.mongodb.BulkWriteError@24cd7085].

我使用的是Mongo 3.0.4 Java Driver。

对于Mongodb-Java 3.0.1及更高版本，您可以使用此逻辑

        MongoClient mongoClient = new MongoClient("localhost",27017);
        MongoDatabase database = mongoClient.getDatabase("testDB");

        MongoCollection<Document> collection = database.getCollection("testColl").withWriteConcern(WriteConcern.FSYNCED);
        BulkWriteOptions options = new BulkWriteOptions();
        options.ordered(false);

        ArrayList<InsertOneModel<Document>> insertList =  new ArrayList<InsertOneModel<Document>>();
        for(int i =0; i<1000;i++){
            Document document= new Document().append("_id",i).append("testdat", "testvalue");;

            insertList.add(new InsertOneModel<Document>(document));
        }

        collection.bulkWrite(insertList, options);

服务器IP上的批量写入操作错误：27017。写错误：[com.mongodb.BulkWriteError@24cd7085]
