spring mvc发送电子邮件错误（查看图片）

Question

这是我在控制器包下的家庭控制器

EmailController.java

package org.convey.example.controller;
import org.convey.example.email.EmailSender;
import org.convey.example.model.EmailMessage;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bi[enter image description here][1]nd.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;
import java.util.Map;


/**
 * $LastChangedDate:  $
 * $LastChangedBy:  $
 * $LastChangedRevision:  $
 */
@Controller

public class EmailController {

     ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("emailConfiguration.xml");
        EmailSender emailSender=(EmailSender)context.getBean("emailSenderBean");


        final static Logger logger = LoggerFactory.getLogger(EmailController.class);


        @RequestMapping(value="/emailForm",method= RequestMethod.GET)
        public ModelAndView displayEmailForm(Map<String, Object> map)
        {

            logger.debug(" setting up the Email form ");

            ModelAndView view=new ModelAndView("EmailFormView");

            //setting up the  required parameter value in the request scope for CommandName parameter
            map.put("email", new EmailMessage());

            return view;

        }



        @RequestMapping(value="/sendEmail",method= RequestMethod.POST)
        public ModelAndView sendEmailUsingGmail(@ModelAttribute("email")EmailMessage email){


            logger.debug(" ********************* ready to send the email **********************");
            logger.debug(" receiver email address [{}]", email.getReceiverEmailAddress());
            logger.debug(" email subject [{}]", email.getSubject());
            logger.debug(" email body [{}]", email.getMessageBody());

            ModelAndView view=new ModelAndView("EmailView");

            view.addObject("emailAddress",email.getReceiverEmailAddress());
            emailSender.sendEmail(email);
            logger.debug(" ********************* email was sent **********************");

            return view;

    }
}

这是我在电子邮件包

下的第二堂课

EmailSender.java

package org.convey.example.email;

import org.convey.example.model.EmailMessage;
import org.springframework.mail.MailSender;
import org.springframework.mail.SimpleMailMessage;

/**
 * $LastChangedDate:  $
 * $LastChangedBy:  $
 * $LastChangedRevision:  $
 */

public class EmailSender {

     private MailSender mailSender;

        public void setMailSender(MailSender mailSender) {
            this.mailSender = mailSender;
        }


        public void sendEmail(EmailMessage emailMessage){

            SimpleMailMessage message = new SimpleMailMessage();

            message.setTo(emailMessage.getReceiverEmailAddress());
            message.setSubject(emailMessage.getSubject());
            message.setText(emailMessage.getMessageBody());
            //sending the message
            mailSender.send(message);

    }

}

这是我在模型包

下的第三个类

EmailMessage.java

package org.convey.example.model;

import org.springframework.stereotype.Component;

/**
 * $LastChangedDate:  $
 * $LastChangedBy:  $
 * $LastChangedRevision:  $
 */
@Component
public class EmailMessage {


     private String receiverEmailAddress;
        private String subject;
        private String messageBody;


        public void setMessageBody(String messageBody){

            this.messageBody=messageBody;
        }

        public String getMessageBody(){

            return this.messageBody;
        }

        public void setReceiverEmailAddress(String receiverEmailAddress){

            this.receiverEmailAddress=receiverEmailAddress;
        }

        public String getReceiverEmailAddress(){

            return this.receiverEmailAddress;
        }


        public void setSubject(String subject) {

            this.subject=subject;
        }

        public String getSubject(){

            return this.subject;
    }
}

这是我的EmailFormView.jsp页面，在该页面下创建了电子邮件表单

EmailFormView.jsp

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ page session="false" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>

<head>
    <title>Email Form</title>
</head>
<body>
<form:form commandName="email" method="POST" action="sendEmail">

    <p>Email Form </p>
    <br/><br/>

    Receiver Email
    <form:input path="receiverEmailAddress"/>
    <br/><br/>

    Subject
    <form:input path="subject"/>
    <br/><br/>

    Message Body

    <br/><br/>

    </br>
    <input type="submit" value="Send Email" />

</form:form>
</body>
</html>

这是我的EmailView.jsp页面，显示电子邮件已成功发送给发件人的邮件

我的问题是，我想在我的邮件正文中设置样式，如字体，粗体，文字大小我如何更改程序???

Answer 1

请勿插入图像以显示错误。检查IDE控制台中的堆栈跟踪并将其复制粘贴到此处。

除此之外，您有404错误，这意味着请求的资源不可用，因为您发送了错误的网址。您发送此email/emailForm并且控制器中有任何处理程序来处理您的请求。在您的情况下，您应该发送/emailForm。

编辑

我错过了您所犯的错误，这是初学者经常犯的错误。 我再次查看了您的图片，并在地址栏中显示：localhost:8080/email/emailForm。如果您在访问stackoverflow网站时查看浏览器地址栏，请执行以下操作：stackoverflow.com/...此处stackoverflow.com是域名，换句话说就是应用程序的根目录。

在您的情况下，域名丢失，您应该有localhost:8080/yourDomain/email/emailForm之类的内容。

您可以通过多种方式在网址中添加它：

a）手动添加

b）使用像<a href="<c:url value="/email/emailForm"/>">....</a>这样的JSTL标记，这是我最喜欢的解决方案，因为<c:url >标记会自动添加应用程序的根目录。

c）获取请求上下文路径：<a href="${request.contextPath}/email/emailForm">....</a>

d）写下<a href="email/emailForm">.....</a>而不是<a href="/email/emailForm">...</a>。事实上，斜杠改变了事物，/email/emailForm与email/emailForm不同。我让你做考试，你会感到惊讶。

这些应该对你有帮助。

除此之外，请修改应用程序的配置，在SpringMVC应用程序中，您有两个主要的上下文：根上下文和servlet上下文。
在你的配置中，你只有一个，我非常喜欢Spring，让你这么做。如果要在应用程序中添加管理安全性等其他功能，则可能会出现问题。
