@RequestHeader注解介绍

1、请求头包含了若干个属性，服务器可据此获知客户端的信息，通过@RequestHeader即可将请求头中的属性值绑定到处理方法的入参中。

2、控制器TestRequestMappingController.java

package com.springmvc.web.controller;

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

@Controller
@RequestMapping("/springmvc")
public class TestRequestMappingController {

	@RequestMapping("/testRequestHeader")
	public String testRequestHeader(
			@RequestHeader("Accept-Encoding") String encoding,
			@RequestHeader("Accept-Language") String language) {
		System.out.println("testRequestParam, encoding="+encoding+",language="+language);
		return "success";
	}

}
