mongoDB数据库原生配置

2.封装mongoDBUtil工具类

 1 //不通过认证获取连接数据库对象
 2     public static MongoCollection<Document> getConnect(){
 3         //连接到 mongodb 服务
 4         MongoClient mongoClient = new MongoClient("ip", 27017);
 5 ?
 6         //连接到数据库
 7         MongoDatabase mongoDatabase = mongoClient.getDatabase("数据库名称");
 8 ?
 9         //连接数据库表
10         MongoCollection<Document> personalData = mongoDatabase.getCollection("表名称");
11 ?
12         //返回连接数据库表对象
13         return personalData;
14     }
15 ?
16     //需要密码认证方式连接
17     public static MongoCollection<Document> getConnect2(){
18         List<ServerAddress> adds = new ArrayList<>();
19         //ServerAddress()两个参数分别为 服务器地址 和 端口
20         ServerAddress serverAddress = new ServerAddress("localhost", 27017);
21         adds.add(serverAddress);
22 ?
23         List<MongoCredential> credentials = new ArrayList<>();
24         //MongoCredential.createScramSha1Credential()三个参数分别为 用户名 数据库名称 密码
25         MongoCredential mongoCredential = MongoCredential.createScramSha1Credential("username", "databaseName", "password".toCharArray());
26         credentials.add(mongoCredential);
27 ?
28         //通过连接认证获取MongoDB连接
29         MongoClient mongoClient = new MongoClient(adds, credentials);
30 ?
31         //连接到数据库
32         MongoDatabase mongoDatabase = mongoClient.getDatabase("test");
33 ?
34         //连接数据库表
35         MongoCollection<Document> personalData = mongoDatabase.getCollection("表名");
36 ?
37         //返回连接数据库对象
38         return personalData;
39     }

测试类

 1  @Test
 2     public void deom01(){
 3         MongoCollection<Document> connect = MongoDBUtil.getConnect();
 4 ?
 5         JSONObject json = new JSONObject();
 6         json.put("111","hasidffhasedfhed");
 7         json.put("222","hasidffhasedfhed");
 8         json.put("333","hasidffhasedfhed");
 9         json.put("444","hasidffhasedfhed");
10         json.put("5555","hasidffhasedfhed");
11         Document json1 = new Document(json);
12         connect.insertOne(json1);
13     }
