请求SpringMVC的Controller，出现404的错误

[u013904882]

Controller文件代码：
@Controller
@RequestMapping("/login")
public class LoginController {
@Resource
private UserServiceDaoImplement userServiceDaoImpl;
@RequestMapping(value="/userLogin", method = RequestMethod.POST)
@ResponseBody
public Map userLogin(HttpServletRequest request,
@RequestParam(value="username") String username,
@RequestParam(value = "password") String password,Map maps) throws Exception{

前端login.HTML的js代码：
$.ajax({
type: "POST",
dataType: "json",
url: "login/userLogin",
data: {"password":password,"username":username},
success: function (data, textStatus) {
alert(data+"==="+textStatus);
window.location.href = 'index.html';
},
error: function(XMLHttpRequest, textStatus, errorThrown) {
alert("登录失败:用户名或密码错误");
}
});


请问大神，可能那里出问题了？

url 可以这样写吗,我一般是'<%=reuqest.getContextPath()%>/xxxx/xxxx.do'

[q_srbzy]

仔细看了下 是UserLogin.jsp 这个页面 找不到,你看下你java放跳转的页面

[ASCII_marvel]

看请求路径貌似是对的，在前端页面写个demo测试一下ajax到底有没有传值给后台，页面和后台分别debug一下

你是不是没配置component-scan

[黑色龙猫]

配置问题嘛，404错误，你的项目根本没有编译成功啊
