Spring MVC @RequestHeader注解用于将请求的头信息数据映射到功能处理方法的参数上。
创建HelloWorldController
package com.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestHeader;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class HelloWorldController {
@RequestMapping("/requestHeaderTest")
public void requestHeaderTest(@RequestHeader("User-Agent")String userAgent,
@RequestHeader(value="Accept")String []accepts) {
System.out.println("通过@RequestHeader获得userAgent");
System.out.println(userAgent);
System.out.println("通过@RequestHeader获得accept");
for(String accept:accepts) {
System.out.println(accept);
}
}
}
创建index.jsp
<%@ page language="java" contentType="text/html; charset=utf-8"
pageEncoding="utf-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>index</title>
</head>
<body>
<a href="requestHeaderTest">requestHeaderTest</a>
