spring mvc 怎么在后台接收到页面上传来的值
3个回答
展开全部
spring mvc属于Java框架技术,
前台数据,以方法参数传入
@RequestMapping(value = "login")
public String login(String username,String password) {
System.out.println(username+"--"+password);
return "login";
}
前台页面input name属性 与方法属性名一致即可

handleRequest(HttpServletRequest arg0,HttpServletResponse arg1)
不是有 HttpServletRequest 吗
直接 arg0.getParameter("daa") 就获得了
然后你的登录页面,点击登录连接是直接打开helloWorld.do所以页面上的表单是没有提交的
XML/HTML code
<a href="helloWorld.do">hello</a>
可以改成,点击登录的时候使表单提交
XML/HTML code
<body>
<h1>欢迎</h1>
<br />
<a href="helloWorld.do">hello</a>
<br/>
<a href="javascript:void(0)" onclick="document.forms[0].submit()">login</a>
<form action="login.do" method="post">
<input type="text" value="ddddd" name="daa"/>
<input type="submit" value="试试"/>
</form>
</body>
