我试图从servlet类通过javamail发送一个Html页面

Servlet

package com.kunal.servlet;

import java.io.IOException;
import java.util.*;
import javax.mail.*;
import javax.mail.internet.*;
import javax.activation.*;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;

import javax.servlet.http.HttpServletResponse;

/**

 */
@WebServlet("/CartCheckout")
public class CartCheckout extends HttpServlet {
    private static final long serialVersionUID = 1L;

    /**

    public CartCheckout() {
        super();
        // TODO Auto-generated constructor stub
    }

    /**

    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        // TODO Auto-generated method stub

    }

    /**

    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        // TODO Auto-generated method stub
        try
        {
            Properties props = new Properties();
            props.put("mail.smtp.host", "smtp.gmail.com");
            props.put("mail.smtp.socketFactory.port", "465");

            props.put("mail.smtp.auth", "true");
            props.put("mail.smtp.port", "465");

            Session session = Session.getDefaultInstance(props,  
                    new javax.mail.Authenticator() {  
                     protected PasswordAuthentication getPasswordAuthentication() {  
                      return new PasswordAuthentication("user","password");  
                     }  
                      });  

            Message message=new MimeMessage(session);
            message.setFrom(new InternetAddress("user"));
            message.setRecipients(Message.RecipientType.TO,InternetAddress.parse("Receiver"));
            message.setSubject("Agro Test");
            message.setContent(message.setContent("<html>\n" +
                    "<body>\n" +
                    "\n" +
                    "<a href=\"http://kunal.blogspot.com\">\n" +
                    "This is a link</a>\n" +
                    "\n" +
                    "</body>\n" +
                    "</html>", "text/html"), "text/html");
            Transport.send(message);  
            System.out.println("message sent...."); 
        }
        catch(MessagingException ex)
        {
            ex.printStackTrace();
        }
        catch(Exception ex)
        {
            ex.printStackTrace();
        }
    }

}

它在

message.setContent（）

处给出了一个错误。

身份验证过程已成功完成，但在创建消息时会产生错误。

这是一个编译器错误。请仔细查看您的代码，您有这个错误

message.setContent(message.setContent("<html>\n" +
                    "<body>\n" +
                    "\n" +
                    "<a href=\"http://kunal.blogspot.com\">\n" +
                    "This is a link</a>\n" +
                    "\n" +
                    "</body>\n" +
                    "</html>", "text/html"), "text/html");

message.setContent（message.setContent（“\n”+
“\n”+
“\n”+
“\n”+
“\n”+
“\n”+
“，”text/html“，”text/html“；

应该是

message.setContent("<html>\n" +
                        "<body>\n" +
                        "\n" +
                        "<a href=\"http://kunal.blogspot.com\">\n" +
                        "This is a link</a>\n" +
                        "\n" +
                        "</body>\n" +
                        "</html>", "text/html");

message.setContent（“\n”+
“\n”+
“\n”+
“\n”+
“\n”+
“\n”+
“”和“text/html”）；

message.setContent（message.setContent

Ops！！我的错！！！谢谢

message.setContent("<html>\n" +
                        "<body>\n" +
                        "\n" +
                        "<a href=\"http://kunal.blogspot.com\">\n" +
                        "This is a link</a>\n" +
                        "\n" +
                        "</body>\n" +
                        "</html>", "text/html");
