Java spring mvc发送电子邮件时出错（检查图像）

java spring spring-mvc

Java spring mvc发送电子邮件时出错（检查图像）,java,spring,spring-mvc,Java,Spring,Spring Mvc,这是控制器包下的我家控制器 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.c

这是我在模型包下的第三节课

EmailMessage.java

package org.convey.example.model;

@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;
    }
}

电子邮件

我的问题是，我想为我的邮件正文设置字体、粗体、文本大小等样式。我该如何更改我的程序？

请不要插入显示错误的图像。检查IDE控制台中的stacktrace并将其复制粘贴到此处

除此之外，还有一个404错误，这意味着请求的ressource不可用，因为您发送了一个错误的URL。您发送此

电子邮件/emailForm

，控制器中有任何处理程序来处理您的请求。在您的情况下，您应该只发送

/emailForm

编辑

我错过了你犯的错误，这是初学者经常犯的错误。我再次查看了您的图像，您的地址栏中有：

localhost:8080/email/emailForm

。如果您在访问stackoverflow网站时查看浏览器地址栏，您会发现：

stackoverflow.com/…

这里

stackoverflow.com

是域，换句话说，是应用程序的根

在您的情况下，域丢失了，您应该有类似于

localhost:8080/yourDomain/email/emailForm

的内容

有几种方法可以将其添加到URL中：

a）手动添加

b）像这样使用JSTL标记

这是我最喜欢的解决方案，因为
