java-email

java实现发邮件，

 

导入mail.jar 和activation.jar，common-email.jar

 

1，发送普通文本EMAIL

代码：

public void sendEmail(String userEmail,String emailTheme,String emailConnection) {
		Properties p = new Properties();
		try {
			p.load(OpinionfeedbackAction.class.getClassLoader().getResourceAsStream("email.properties"));
			String emailName = p.getProperty("email.name");
			String emailPwd = p.getProperty("email.password"); 
			String hostName = p.getProperty("email.hostname");
			String emailFullName = p.getProperty("email.fullName");
			//System.out.println("emialFullName:"+ emailFullName);
			Email email = new SimpleEmail();
			email.setHostName(hostName);
			email.setAuthentication(emailFullName,emailPwd);//这里写emailName也可以
			email.setCharset("UTF-8");
			email.setTLS(true);
			//email.setFrom(new InternetAddress(emailFullName,"国家林业科学数据平台").toString());//这里改昵称,也许会报错
			email.setFrom(emailFullName,"普通邮件测试");//这里改昵称
			email.setSubject(emailTheme);
			email.setMsg(emailConnection);
			
			email.addTo(userEmail);
			email.send();
		} catch (Exception e1) {
			e1.printStackTrace();
		}
		
		
	}

 

email.properties配置文件：

 

email.name=emailUsername
email.password=pwd
email.hostname=smtp.forestdata.cn
email.fullName=[e-mail]

 

 

可能遇到问题：

 

错误一： 
Exception in thread "main" java.lang.NoClassDefFoundError: com/sun/mail/util/LineInputStream 
解决方法：到D:\MyEclipse 6.5 

\myeclipse\eclipse\plugins\com.genuitec.eclipse.j2eedt.core_6.5.0.zmyeclipse650200806 

\data\libraryset\EE_5目录下找到javaee.jar删除其中到mail文件夹。 

错误二： 
Exception in thread "main" java.lang.NoClassDefFoundError: com/sun/mail/util/BEncoderStream 
解决方法： 
下载mail.jar和activation.jar文件加入到工程中。

 

 

 

2，发送HTML邮件。

其实也就是把Email e = new SimpleEmail()改为HtmlEmail e = new HtmlEmail();

然后再把发送内容的方法改为：e.setHtmlMsg(Content);即可

具体代码如下：

 

package com.peng;
import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.FileReader;
import java.io.FileWriter;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.io.OutputStreamWriter;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.ArrayList;
import java.util.Enumeration;
import java.util.List;
import java.util.zip.ZipInputStream;
import java.util.zip.ZipOutputStream;

import org.apache.commons.mail.Email;
import org.apache.commons.mail.HtmlEmail;
import org.apache.commons.mail.SimpleEmail;
import org.apache.struts2.ServletActionContext;
import org.apache.tools.zip.ZipEntry;
import org.apache.tools.zip.ZipFile;

public class EmailTest {

	public static void main(String[] args) throws Exception {
	
		//String inputpath = "D:\\zipTest";
		//String zipOutpath = "D:\\ziptest.zip";
		//zipTest(inputpath,zipOutpath);
		// unZip ( "D:\\ziptest.zip" , "D://opt" );
		StringBuilder c = new StringBuilder();
		c.append("<a href=\"http://www.baidu.com\">链接到百度<a>");
		c.append("<div style=\" color:red;\">红色DIV</div>");
		
		SendEmail("[e-mail]", c.toString(),"邮件测试");
	}

	
	

	
	
	public static void SendEmail(String email,String content,String theme) throws Exception{
		
		//Email e = new SimpleEmail();
		HtmlEmail e = new HtmlEmail();
		e.setHostName("smtp.163.com");
		e.setAuthentication("pengenjing","pwd");
		e.setCharset("Utf-8");
		e.setTLS(true);
		e.setFrom("[e-mail]","HTML测试");
		
		e.setSubject(theme);
		//e.setMsg(content);
		e.setHtmlMsg(content);
		e.addTo(email);
		e.send();
	}
	
	
	
	
	
	}

 

 3，发送附件

 

public String sendEnclosure() throws EmailException{  
        String result = null;  
        EmailAttachment emailattachment = new EmailAttachment();  
           //设置附件路径  
           emailattachment.setPath(file);  
           //System.out.println(path);  
           emailattachment.setDisposition(EmailAttachment.ATTACHMENT);  
           //附件描述  
           emailattachment.setDescription("This is Smile picture");  
           /*  
            * 设置附件的中文乱码问题，解决附件的中文名称 乱码问题  
            */    
           BASE64Encoder enc = new BASE64Encoder();    
           //this.getName().getBytes()使用的是系统缺省的编码处理,这里是GBK    
           emailattachment.setName("=?GBK?B?"+enc.encode(file.getBytes())+"?=");    
               
           //attachment.setName(this.getName()); //不处理字符集的话,发送的附件中文名称是乱码   
             
             
           //创建一个email  
           MultiPartEmail multipartemail = new MultiPartEmail();  
           //设置主机名称  
           multipartemail.setHostName(UserInfo.sendHost);  
           //设置字符编码  
           multipartemail.setCharset("GB2312");  
           //设置发送邮件目的地址  
           multipartemail.addTo(to);  
           //设置发送又见源地址  
           multipartemail.setFrom(from);  
           //设置用户名和密码  
           multipartemail.setAuthentication(UserInfo.username, UserInfo.password);  
           //设置主题  
           multipartemail.setSubject(subject);  
           //设置邮件内容  
           multipartemail.setMsg(msg);  
           //添加附件  
           multipartemail.attach(emailattachment);  
           //发送邮件  
           multipartemail.send();  
  
           result = "The attachmentEmail send sucessful!!!";  
  
           return result;  
    }
