Controller

package com.zz.controller;

import java.util.HashMap;
import java.util.Map;

import org.springframework.web.bind.annotation.CookieValue;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestHeader;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

import com.zz.entity.User;

@RestController
@RequestMapping("test")
public class TestController {
	
	//路径传值
	@RequestMapping("t1/{p1}")
	public Map T1(@PathVariable("p1") String parameter1){
		Map map=new HashMap();
		map.put("rs", parameter1);
		return map;
	}
	//？传值
	@RequestMapping("t2")
	public Map T2(@RequestParam("p2") String parameter2){
		Map map=new HashMap();
		map.put("rs", parameter2);
		return map;
	}
	
	//Body参数
	//application/jason
	@RequestMapping("t3")
	public Map T3(@RequestBody User person){
		Map map=new HashMap();
		map.put("rs", person.getName());
		return map;
	}
	
	//无注解（form提交）
	//form-data
	@RequestMapping("t4")
	public Map T4(User person){
		Map map=new HashMap();
		map.put("rs", person.getName());
		map.put("rs2", person.getPwd());
		return map;
	}
	
	//请求头参数以及Cookie
	@RequestMapping("t5")
	public Map t5(@RequestHeader(name="myHeader") String myHeader,
					@CookieValue(name="myCookie") String myCookie){
		
		System.out.println("myHeader"+myHeader);
		System.out.println("myCookie"+myCookie);
		Map map=new HashMap();
		map.put("rs", myHeader);
		map.put("rs2",myCookie);
		return map;
	}
	 
//	表单的参数写在Controller相应的方法的形参中
//	适用于get方式提交，不适用于post方式提交。
	@RequestMapping("t6")
	public Map t6(String name,String pwd){
		Map map=new HashMap();
		map.put("rs", name);
		map.put("rs2",pwd);
		return map;
	}
}
