Spring3 MVC Annotaction REST 入门(登录示例)

一 开发工具环境:Myeclipse6.6+Tomcat7+JDK1.6
所用jar文件:

二 示例代码如下:
WEB控制层

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import com.spring.rest.entitys.User;

@Controller  //声明控制器  
@RequestMapping("/user")//url
public class UserController {

	@RequestMapping(value = "/login")
	public String test(HttpServletRequest request,
			HttpServletResponse response, User userinfo) {
		if (userinfo.getUsername().equals("jack")
				&& userinfo.getPassword().equals("111111")) {
			request.setAttribute("user", userinfo);
			return "users/list";
		} else {
			return "users/loginerr";
		}
	}
	
	@RequestMapping(value = "/login2")
	public String test2(HttpServletRequest request,
			HttpServletResponse response, User userinfo) {
		if (userinfo.getUsername().equals("david")
				&& userinfo.getPassword().equals("david")) {
			request.setAttribute("user", userinfo);
			return "users/list";
		} else {
			return "users/loginerr";
		}
	}

}

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

@Controller
@RequestMapping("/topic")

	@RequestMapping(value = "/{id}",method=RequestMethod.GET)
	public String helloWorld(
			@PathVariable Long id, 
			HttpServletRequest request,

		return  "topic" ;
	}
	
	
	@RequestMapping(value="/add")
	public String test(HttpServletRequest request,   
            HttpServletResponse response){
		System.out.println("Hello www.JavaBloger.com ");
		request.setAttribute("message", "Hello JavaBloger ! ,@RequestMapping(value='/add')");

	}
	
	@RequestMapping(value="/update")

		request.setAttribute("message", "Hello JavaBloger ! ,@RequestMapping(value='/update')");

	}
}

import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;


@Controller
public class URITemplatesController {
	
	@RequestMapping(value="/owners/{ownerId}", method=RequestMethod.POST)
	//org.springframework.ui.Model与org.springframework.ui.ModelMap功能相似
	public String findOwner(@PathVariable String ownerId,@RequestParam String username,@RequestParam String password, ModelMap model) {
	  System.out.println("ownerId: "+ownerId+",username:" + username+",password: " + password);
	  model.addAttribute("url", "http://liuzidong.iteye.com");
	  model.addAttribute("username",username);
	  model.addAttribute("password",password);
	  return "urlTemplate"; 
	}	
}
