如何使用Java将数组添加到MongoDB文档?

本文介绍了如何使用Java将数组添加到MongoDB文档?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我想使用Java驱动程序在mongoDB中创建以下文档架构

I want to create the following document schema in mongoDB using the java driver

{ "_id": { "$oid": "513e9820c5d0d8b93228d7e8" }, "suitename": "testsuite_name", "testname": "testcase_name", "milestones": [ { "milestone_id": "359", "testplans": [ { "pland_id": "965", "runs": [ 6985, 5896 ] }, { "plan_id": "984", "runs": [ 9856, 3684 ] } ] } ] }

我有以下代码

BasicDBObject testObject = new BasicDBObject(); BasicDBObject milestoneObject = new BasicDBObject(); testObject.put("suitename", testsuite); testObject.put("testname", testcase); testObject.put("milestones", new BasicDBObject("milestone_id", "2333")); locations.insert(testObject);

但是，这并没有生成里程碑作为数组.如何将里程碑添加为数组?我目前使用我的代码

But this is not generating milestone as an array. How can I add milestone as an array? I currently get this using my code

{ "_id": { "$oid": "513f93dac5d0e2439d34308e" }, "suitename": "test_deployment_disable_client.TestDeploymentDisableClient", "testname": "test_deployment_disable_client", "milestones": { "milestone_id": "2333" } }

推荐答案

更改为以下内容:

testObject.put("suitename", testsuite); testObject.put("testname", testcase); List<BasicDBObject> milestones = new ArrayList<>(); milestones.add(new BasicDBObject("milestone_id", "2333")); testObject.put("milestones", milestones); locations.insert(testObject);
