java中mongoTemplate批量更新

方法：mongoTemplate.getDb().getCollection(tableName).bulkWrite(requests);

 

public BulkWriteResult bulkWrite(List> requests,String tableName) {
            BulkWriteResult write = mongoTemplate.getDb().getCollection(tableName).bulkWrite(requests);
return write;
}

 

BulkWriteResult write = mongoTemplate.getDb().getCollection(tableName).bulkWrite(requests);

 

难点在与如何拼接参数List> requests

 

例子：

DBObject queryObject = new BasicDBObject();
queryObject.put("doctorId",doctorId);
DBObject fields = new BasicDBObject();
fields.put("_id",1);
String tableName = Constant.hospitalInfo.getPrefixNo().toLowerCase()+"-record";
List
