JAVA傳送郵件最全示例
阿新 • • 發佈:2019-01-10
傳送郵件是我們在程式開發中很常見的功能,比如註冊通知、找回密碼等,在網上也有很多關於JAVA傳送郵件的示例,但多數都是隻介紹了其中的一部分,今天為大家提供一些JAVA傳送各種形式郵件的示例,供大家學習參考。
JAVA Mail
JAVA Mail是很常用的用於傳送郵件的包,我們可以從這裡獲取,或者在maven中新增如下配置:
<dependency>
<groupId>com.sun.mail</groupId>
<artifactId>javax.mail</artifactId>
<version >1.5.5</version>
</dependency>
如果使用junit測試還需要新增:
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.8.2</version>
</dependency>
示例程式碼如下:
package com.gujin.mail;
import java.io.File;

import javax.activation.DataSource;
import javax.activation.FileDataSource;

import javax.mail.internet.MimeBodyPart;
import javax.mail.internet.MimeMessage;

import javax.mail.internet.MimeUtility;

}
});
// 根據session建立一個郵件訊息

// 設定郵件訊息的傳送者

commons-email
使用JAVA Mail我們可以完成郵件的傳送,但是我們可以發現實現過程略顯複雜,比較繁瑣,所以我們可以藉助commons-email簡化傳送郵件的過程,commons-email可以從這裡下載,或在maven中新增如下配置:
<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-email</artifactId>
<version>1.4</version>
</dependency>
示例程式碼:

import org.apache.commons.mail.SimpleEmail;
public class CommonsEmailTest
{
private String host = "smtp.126.com";

private String to = "";
