java操作mongodb案例分析（含代码）

java操作mongodb案例分析（含代码）：

一、mongodb安装（版本：mongodb-win32-x86_64-2008plus-2.4.14.zip）：

         具体步骤可参考（http://jingyan.baidu.com/article/d5c4b52bef7268da560dc5f8.html）

        1、下载地址：

             https://fastdl.mongodb.org/win32/mongodb-win32-x86_64-2008plus-2.4.14.zip?_ga=1.167203774.1858851621.1438174880

             下载完成后解压到D盘，目录结构为： D:/mongodb/bin

        2、输入如下的命令启动mongodb服务：

           D:/mongodb/bin>mongod --dbpath D:\mongodb\data\db

        3、在浏览器输入：http://localhost:27017/，将会提示下面的信息：

    

You are trying to access MongoDB on the native driver port. For http diagnostic access, add 1000 to the port number”

        

       4、我们把端口号加上1000后，再访问下，会打开下面的页面：

5、测试连接

另开一个cmd窗口，原来的那个窗口不要关闭，如果窗口关闭则服务也关闭

首先通过cd命令切换到Mongodb\bin目录下，然后通过mongo ip:port 命令来连接数据库

ip代表我们需要访问的数据库服务的ip，port代表数据库服务的端口

Dos代码  

1. C:\Documents and Settings\chenzhou>D:   
2. D:\>cd Mongodb\bin   
3. D:\Mongodb\bin>mongo 127.0.0.1:27017  
4. MongoDB shell version: 2.0.2-rc2   
5. connecting to: 127.0.0.1:27017/test   
6. >  

C:\Documents and Settings\chenzhou>D:
D:\>cd Mongodb\bin
D:\Mongodb\bin>mongo 127.0.0.1:27017
MongoDB shell version: 2.0.2-rc2
connecting to: 127.0.0.1:27017/test
>

代表访问成功，连接到test库

如上例子中127.0.0.1代表本机，27017是Mongodb服务端默认端口

如果我们在配置mongodb服务时使用的是默认的端口，那么我们在通过客户端访问时可以不用指定访问的ip和port

Dos代码  

1. C:\Documents and Settings\chenzhou>D:   
2. D:\>cd Mongodb\bin   
3. D:\Mongodb\bin>mongo   
4. MongoDB shell version: 2.0.2-rc2   
5. connecting to: test   
6. >  

C:\Documents and Settings\chenzhou>D:
D:\>cd Mongodb\bin
D:\Mongodb\bin>mongo
MongoDB shell version: 2.0.2-rc2
connecting to: test
>

  同样地，访问成功，连接到test库
