官方文檔參考:
http://www.mkyong.com/mongodb/ 用MyEclipse添加maven-Project工程，在這之前你可能需要配置你的m2eclipse
1.將maven配置成你自己安裝的版本。
2.設(shè)置User Settings
當然也可以修改倉庫默認目錄，打maven安裝目錄conf/setting.xml
在<settings>節(jié)點里
添加：<localRepository>d:/myrepository</localRepository>即可
pom.xml

寫完pom.xml后，執(zhí)行 項目-右鍵-run-maven install
下載完jar包，Test 成功后，就可以寫代碼了。

package com.config;
import org.springframework.context.annotation.Bean;

實體類:
package entity;

public class User
{
private String id;
private String username;
private String password;
//文檔中的集合
private List<String> position;
// 要有聲明默認的構(gòu)造方法，不然查詢的時候會報錯(無法實例化)
public User()

public String getId()
{
