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"; }
