java 邮件发送

 java中，发送邮件可以使用 commons-email.jar

首先我们需要找到对应的jar，可以手动下载，或者直接maven；

maven地址如下：

<!-- https://mvnrepository.com/artifact/org.apache.commons/commons-email -->
 <dependency>
     <groupId>org.apache.commons</groupId>
     <artifactId>commons-email</artifactId>
     <version>1.5</version>
 </dependency>

 

 测试例子：

import org.apache.commons.mail.DefaultAuthenticator;
import org.apache.commons.mail.EmailException;
import org.apache.commons.mail.HtmlEmail;

public class EmailTest {
    public static void main(String[] args) {
        String htmlContent = "你好！<br/>你的验证码为：<span style='font-size: 20px;color: #009688'> 54ZSD25 </span>（10分钟内有效）<br/>";

        EmailP email = new EmailP();
        email.setHostName("smtp.aliyun.com");
        email.setUserName("用户名");
        email.setUserPwd("密码");
        email.setNickName("发送者昵称");
        email.setToEmail("接受者邮箱");
        email.setTitle("邮箱标题");
        email.setHtmlContent(htmlContent);

        System.out.println(sendHtmlEmail(email));
    }

    /**
