通過common-emai類庫發送普通郵件和帶有附件的郵件的完整示例
1.此示例是通過maven構建,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> </pre>
2.工具類如下：import java.net.URL;import org.apache.commons.mail.DefaultAuthenticator;
import org.apache.commons.mail.EmailAttachment;
import org.apache.commons.mail.EmailException;
import org.apache.commons.mail.MultiPartEmail;
import org.apache.commons.mail.SimpleEmail;/**

3.測試類如下：import com.ilucky.util.email.EmailUtil;
/**
- @author IluckySi
- @since 20150108
注意:以后可以擴展回復郵件,定時發送等. */
public class MainTest {public static void main(String[] args) {
//發送普通郵件. //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("sidongxue@sohu.com"); eu.setTo("sidongxue@sohu.com"); eu.setSubject("測試郵件"); eu.setMsg("親,這是一封測試郵件!"); System.out.println("發送郵件結果: " + 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("sidongxue@sohu.com"); String[] tos = new String[]{"1151262684@qq.com", "570258762@qq.com"}; eu.setTos(tos); String[] ccs = new String[]{"1016336364@qq.com", "pengzhongchen@gmail.com"}; eu.setCcs(ccs); String[] bccs = new String[]{"1198377646@qq.com", "sidongxue@sohu.com"}; eu.setBccs(bccs); eu.setSubject("測試郵件"); eu.setMsg("親,這是一封測試郵件,如果收到郵件,請及時回復,十分感謝,如果回復晚了,后果自負!"); System.out.println("發送郵件結果: " + 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("sidongxue@sohu.com"); eu.setTo("sidongxue@sohu.com"); eu.setSubject("測試郵件"); eu.setMsg("親,這是一封測試郵件!"); eu.setAttachmentName("哈哈"); eu.setAttachDescription("這是一個文件,點我!"); eu.setLocalAttachmentPath("D:\\ilucky\\新建文本文檔22.txt"); System.out.println("發送郵件結果: " + eu.sendWithMsgAndAttachment());}
} </pre>
注意：eu.setDefaultAuthenticatorUsername("sidongxue"); eu.setDefaultAuthenticatorPassword("123456");此處用自己的郵箱用戶名和密碼.
