问题描述

发送电子邮件时，我使用 commons-email-1.3 收到以下错误.
我已经下载并添加了外部 jar 到项目中.
请帮我解决这个问题！

While sending email I am getting the following errors using commons-email-1.3.
I have downloaded and added external jar's to the project.
Please help me fix this problem!

package mypkg;

import org.apache.commons.mail.DefaultAuthenticator;
import org.apache.commons.mail.Email;
import org.apache.commons.mail.SimpleEmail;

public class sendingmail {
     public static void main(String[] args)  throws Exception {
            Email email = new SimpleEmail();
            email.setSmtpPort(587);
            email.setAuthenticator(new DefaultAuthenticator("myid","mypwd")); //Here is the error
            email.setDebug(false);
            email.setHostName("smtp.gmail.com");
            email.setFrom("me@gmail.com");
            email.setSubject("Hi");
            email.setMsg("This is a test mail ... :-)");
            email.addTo("you@gmail.com");
            email.setTLS(true);
            email.send();
            System.out.println("Mail sent!");

    }
}

给出错误的行是

email.setAuthenticator(new DefaultAuthenticator("myid","mypwd"));

错误信息是

线程main"java.lang.Error 中的异常:未解决的编译问题:

Exception in thread "main" java.lang.Error: Unresolved compilation problems:

无法解析类型 javax.mail.Authenticator.它是从所需的 .class 文件中间接引用的
来自类型 Email 的方法 setAuthenticator(Authenticator) 指的是 mypkg.mailtest.main(mailtest.java:13) 处缺少的类型 Authenticator

The type javax.mail.Authenticator cannot be resolved. It is indirectly referenced from required .class files
The method setAuthenticator(Authenticator) from the type Email refers to the missing type Authenticator at mypkg.mailtest.main(mailtest.java:13)
