问题：

Bean名称'setupuser'的BindingResult和普通目标对象都不可用作请求属性

於功
2023-03-14

我试图在Tomcat 8.0服务器上使用Spring框架开发一个网络应用程序，但是，我被这个错误卡住了。其他两个表单页能够通过使用ModelAtinn绑定表单中的数据，然而，第三个userprofile.jsp是抛出错误“BindingResult或bean名称'setupuser'的普通目标对象都不可用作请求属性”。请帮我改掉这个错误。谢啦

错误-

您可以尝试在函数级别而不是类级别上注释请求映射：

但首先要加上

<mvc:annotation-driven />

到你的onlineEnrollment-servlet.xml

还有xmlns:mvc=”http://www.springframework.org/schema/mvc“在顶部

现在尝试更改控制器方法（只需完全复制到您的代码）到：

  package com.banking.onlineenrollment.controller;
    import javax.validation.Valid;

    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Controller;
    import org.springframework.validation.BindingResult;
    import org.springframework.web.bind.annotation.ModelAttribute;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RequestMethod;
    import org.springframework.web.servlet.ModelAndView;
    import com.banking.onlineenrollment.service.UserService;
    import com.banking.onlineenrollment.user.UserProfileForm;

    /**
     * @author Harsh
     *
     */
    @Controller
//    @RequestMapping(value = "/userprofile.do")
    public class UserProfileController {
        private UserService userService;

        @Autowired
        public UserProfileController(UserService userService) {
            // TODO Auto-generated constructor stub
            this.userService = userService;
        }

        @RequestMapping(value="/askform.do",method = RequestMethod.GET)
        public ModelAndView displayUserProfile() {
            ModelAndView mv = new ModelAndView("userprofile");
            UserProfileForm userProfileForm = new UserProfileForm();
            mv.addObject("setupuser", userProfileForm);
            return mv;
        }

        @RequestMapping(value="/populateformfield.do",method = RequestMethod.POST)
        public ModelAndView processUserProfile(@Valid @ModelAttribute("setupuser") UserProfileForm userProfileForm, BindingResult result) { 
            System.out.println("Inside POST method beginning of userprofile");
            ModelAndView mv = new ModelAndView();
            if(result.hasErrors()) {
                mv.setViewName("userprofile");
                mv.addObject("message", "Don't leave the form blank");
            }
            else {
                userService.saveUserProfile(userProfileForm.getEmail(),userProfileForm.getConfirmEmail(),userProfileForm.getUsername(),userProfileForm.getPassword(), userProfileForm.getConfirmPassword());
                mv.setViewName("securityprofile");
            }
            return mv;
        }
    }

现在将userProfile.jsp更改为：

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
         pageEncoding="ISO-8859-1"%>
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
        <title>Setup User Profile</title>
    </head>
    <body>
        <h3>4.Setup User Profile</h3>
        The following is required to complete your user profile.<br /><c:out value="${message}"></c:out><br /><br />
    <b>Setup your contact information:</b> <br />

    <form:form method="POST" modelAttribute="setupuser" action="populateformfield.do">
        EMAIL ADDRESS:  <form:input path="email" /> <br />
        <form:errors path="email" cssStyle="" cssClass="color:red;" /><br />
        CONFIRM EMAIL ADDRESS: <form:input path="confirmEmail" /> <br />
        <form:errors path="confirmEmail" cssClass="color:red;" /><br /><br />
        <b>Setup your username and password:</b><br />
        USERNAME:  <form:input path="username" /> <br />
        <form:errors path="username" cssClass="color:red;" /><br />
        PASSWORD:  <form:password path="password" /> <br />
        <form:errors path="password" cssClass="color:red;" /><br />
        CONFIRM PASSWORD:  <form:password path="confirmPassword" /> <br />
        <form:errors path="confirmPassword" cssClass="color:red;" /><br />
        <input type="submit" value="Continue"> <br /><br />

        Password Complexity Requirements
        Your password cannot contain your username.
        Your password must be a minimum of 8 characters and must
        meet at least 3 of the following 4 categories:
        English uppercase characters (A - Z)
        English lowercase characters (a - z)
        Numeric digits (0 - 9)
        Non-alphanumeric (For example: !, $, #, or %)
        Passwords are case sensitive. For added security we
        recommend that you change your password every 90 days.
    </form:form>
</body>
</html>

现在请求带有askform.do的表单
