java post和get请求问题 用的是ssm get可以获取到值 post 获取的值为null
</div>
<form action="<%=basePath%>user/checkUser.do" method="post" id='login-form' class="mui-input-group" style="background-color: rgba(0, 0, 0, 0);" enctype="application/x-www-form-urlencoded">
<div class="mui-input-row">
<label><a><span class="mui-icon-extra mui-icon-extra-phone"></span></a></label>
<input id='account' type="text" class="mui-input-clear mui-input" placeholder="请输入您的手机号码" name="pic_name">
<input type="hidden" value="12321456" name="hidden">
</div>
<div class="mui-input-row">
<label><a><span class="mui-icon mui-icon-locked"></span></a></label>
<input id='password' type="password" class="mui-input-clear mui-input" placeholder="请输入密码" name="pic_password">
</div>
</form>
后台
@RequestMapping(value="checkUser.do")
public String checkUser(HttpServletRequest request, HttpServletResponse response, User user)
throws Exception {
System.out.println(user.getPic_name()+"welcome to~");
String isTrue = userService.checkUser(user);
if (isTrue != null && isTrue.equals("0")) {
request.getSession().setAttribute("user", user);
System.out.println("正在进入验证用户页面");
response.sendRedirect(request.getContextPath() + "/");
}
else if (isTrue != null && isTrue.equals("1")) {
System.out.println("admin进入");
request.getSession().setAttribute("admin", user.getPic_name());
request.getRequestDispatcher("/user/admin.do").forward(request, response);
}
else {
request.setAttribute("error", "您输入的密码或用户名错误");
request.getRequestDispatcher("/user/login.do").forward(request, response);
}
return null;
}
