springmvc乱码疑惑

有如下代码:在点击URL方式的时候name参数的中文在后台可以正确显示，但是在浏览器直接输入中文的时候为什么后台就是乱码了[code="java"]<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

index

<a href="${pageContext.request.contextPath}/user/welcome?name=哈哈">URL方式</a>

<form action="${pageContext.request.contextPath}/user/login" method="post">
    <span>用户名</span><input type="text" name="username" /><br/>
    <span>密&nbsp;&nbsp;&nbsp;&nbsp;码</span><input type="password" name="password" /><br/>
    <input type="submit" value="登录" />
</form>

[/code]
Controller：[code="java"] @RequestMapping(value = "/welcome",method = RequestMethod.GET)
public String welcome(ModelMap model,HttpServletRequest request){

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

    System.out.println("*********"+name+"*************");

    model.put("name", name);

    System.out.println("*********welcome*************");

    return "welcome";
