最近在做基于mongodb的spring项目架构，有个问题跟大家分享一下，也方便自己以后能够用到
先看一个简单的项目架构：
在架构方面唯一需要说的是采用的是spring的注解：
下面是部分代码，部分。
/**
* @author jessonlv
* 用户注册接口
*/
<strong>@Controller
@RequestMapping("/user")</strong>
public class UserInfoController {
@Autowired
private UserInfoManager userManager;
//接口文档
<strong>@RequestMapping(method=RequestMethod.GET)</strong>
public String list(HttpServletRequest request,HttpServletResponse response){
response.setContentType("text/html;charset=utf-8");
return "user";
}
//检测用户信息-根据帐户
<strong>@RequestMapping(value="/check",method=RequestMethod.GET)
</strong> public String getUser(HttpServletRequest request,HttpServletResponse response) throws Exception{
//设置HTTP头
response.setContentType("text/html;charset=utf-8");
//参数获取
String account=StringUtil.formatStringParameter(request.getParameter("account"), null);
String key=StringUtil.formatStringParameter(request.getParameter("key"), null);//验证调用方
//参数有效性验证
if(account==null){
throw new ParameterException();
}
//TODO:key验证
//查询对象
BasicDBObject o=new BasicDBObject("account",account);
try {
//取数据库
DBObject doc=userManager.getUserInfo(o);
//输出结果
PrintWriter writer=response.getWriter();
writer.write(doc.toString());
} catch (Exception e) {
e.printStackTrace();
//输出结果
PrintWriter writer=response.getWriter();
writer.write(new BasicDBObject().toString());
}
//db.find(query).skip(pos).limit(pagesize)分页
return null;
}采用mongodb的最大好处中的其中一个就是不用写bean，只需做一些简单的配置
我们看spring-servlet.xml 的配置内容

道理其实还是和bean是一样的，这在项目启动的前期都已经映射了。每写一个dao就配置一个
接口的输出结果也很简单：DBObject myDocDbObject = userManager.getUserInfo(repeatAccount);
String str = myDocDbObject.toString(); 是一个json格式的字符。
呵呵，做个小总结，方便忘记了。
