通过common-emai类库发送普通邮件和带有附件的邮件的完整示例

1.此示例是通过maven构建,pom.xml文件如下：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">  <modelVersion>4.0.0</modelVersion>  <groupId>com.ilucky.util.email</groupId>  <artifactId>email-util</artifactId>  <version>1.0-SNAPSHOT</version>  <packaging>war</packaging>  <name>email-util</name>  <url>http://maven.apache.org</url>  <properties>    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>  </properties>  <dependencies><dependency><groupId>org.apache.commons</groupId><artifactId>commons-email</artifactId><version>1.3.3</version></dependency>  </dependencies></project>

2.工具类如下：

{email.setHostName(hostName);email.setAuthenticator(new DefaultAuthenticator(defaultAuthenticatorUsername,

(EmailException e) {System.out.println("发送邮件失败: " + e);} catch (Exception e) {System.out.println("发送邮件失败: " + e);}return result;}}

3.测试类如下：

package com.ilucky.util;import com.ilucky.util.email.EmailUtil;/** * @author IluckySi * @since 20150108 *  * 注意:以后可以扩展回复邮件,定时发送等. */public class MainTest {public static void main(String[] args) {//发送普通邮件.//post1();//post2();post3();}public static void post1() {EmailUtil eu = new EmailUtil();eu.setHostName("smtp.sohu.com");eu.setPort(25);eu.setDefaultAuthenticatorUsername("sidongxue");eu.setDefaultAuthenticatorPassword("123456");eu.setCharset("GB2312");eu.setTimeout(16000);eu.setFrom("[e-mail]");eu.setTo("[e-mail]");eu.setSubject("测试邮件");eu.setMsg("亲,这是一封测试邮件!");System.out.println("发送邮件结果: " + eu.sendWithMsg());}public static void post2() {EmailUtil eu = new EmailUtil();eu.setHostName("smtp.sohu.com");eu.setPort(25);eu.setDefaultAuthenticatorUsername("sidongxue");eu.setDefaultAuthenticatorPassword("123456");eu.setCharset("GB2312");eu.setTimeout(30000);eu.setFrom("[e-mail]");String[] tos = new String[]{"[e-mail]", "[e-mail]"};eu.setTos(tos);String[] ccs = new String[]{"[e-mail]", "[e-mail]"};eu.setCcs(ccs);String[] bccs = new String[]{"[e-mail]", "[e-mail]"};eu.setBccs(bccs);eu.setSubject("测试邮件");eu.setMsg("亲,这是一封测试邮件,如果收到邮件,请及时回复,十分感谢,如果回复晚了,后果自负!");System.out.println("发送邮件结果: " + eu.sendWithMsg());}public static void post3() {EmailUtil eu = new EmailUtil();eu.setHostName("smtp.sohu.com");eu.setPort(25);eu.setDefaultAuthenticatorUsername("sidongxue");eu.setDefaultAuthenticatorPassword("123456");eu.setCharset("GB2312");eu.setTimeout(16000);eu.setFrom("[e-mail]");eu.setTo("[e-mail]");eu.setSubject("测试邮件"); eu.setMsg("亲,这是一封测试邮件!");eu.setAttachmentName("哈哈");eu.setAttachDescription("这是一个文件,点我!");eu.setLocalAttachmentPath("D:\\ilucky\\新建文本文档22.txt");System.out.println("发送邮件结果: " + eu.sendWithMsgAndAttachment());}}

注意：

eu.setDefaultAuthenticatorUsername("sidongxue");eu.setDefaultAuthenticatorPassword("123456");此处用自己的邮箱用户名和密码.
