SpringMVC后台接受前台传值的方法

1.HttpRequestServlet 接收前台传值

@RequestMapping("/go5")

    public String hello5(HttpServletRequest request){

        String name=request.getParameter("uname");

        String id=request.getParameter("uid");

        System.out.println(id+"----"+name);

        return "/WEB-INF/jsp/index.jsp";

    }

2.直接接收前台传值

 //接收单个参数

     @RequestMapping("/hello")

     public String hello(String name){

         System.out.println(name);

         return "/WEB-INF/jsp/index.jsp";

     }

//接收多个参数

     @RequestMapping("/go2")

    public String hello3(String name,int id){

         System.out.println(name);

         System.out.println(id);

         return "/WEB-INF/jsp/index.jsp";

     }

3.以对象形式接收前台传递的数据

//以对象形式接受参数

     @RequestMapping("/go4")

     public String hello5( Student stu){

         System.out.println(stu.getName());

         System.out.println(stu.getId());

         return "/WEB-INF/jsp/index.jsp";

     }

public class Student {//类中必须要有无参数构造函数不然会有java.lang.NoSuchMethodException: org.entity.Student.<init>()错误

     private int id;

     private String name;

    public Student(int id, String name) {

        super();

        this.id = id;

        this.name = name;

    }

    public Student() {

        super();

    }

}

4.restful风格

//restful风格

     @RequestMapping("/detete/{uid}/{uname}")

     public String hello2(@PathVariable("uid")int id,@PathVariable("uname")String name){

         System.out.println(id+"  ---->"+name);

         return "/WEB-INF/jsp/index.jsp";

     }
