[Java教程]java利用commons


本例中利用commons-email发送邮件并进行封装,支持html内容和附件;Commons Email是Apache的Commons子项目下的一个邮件客户端组件,它是基于JavaMail的,大大简化了邮件的收发操作。

所需jar包:commons-email-1.4.jar和mail.jar ,jar包下载地址 http://files.cnblogs.com/files/haha12/%E5%8F%91%E9%80%81%E9%82%AE%E4%BB%B6%E6%89%80%E9%9C%80jar%E5%8C%85.rar
代码如下:

MailInfo.java:邮件实体类

package com.test.mail;import java.util.List;import org.apache.commons.mail.EmailAttachment;/** * 邮件相关信息 * */public class MailInfo {    // 收件人  private List<String> toAddress = null;  // 抄送人地址  private List<String> ccAddress = null;  // 密送人  private List<String> bccAddress = null;  // 附件信息  private List<EmailAttachment> attachments = null;  // 邮件主题  private String subject;  // 邮件的文本内容  private String content;  public List<String> getToAddress() {    return toAddress;  }  public void addToAddress(String toAddress) {    this.toAddress.add(toAddress);  }  public void addToAddress(List<String> toAddress) {    this.toAddress.addAll(toAddress);  }  public void addCcAddress(List<String> ccAddress) {    if (null != ccAddress && ccAddress.size() > 0)      this.ccAddress.addAll(ccAddress);  }  public List<EmailAttachment> getAttachments() {    return attachments;  }  public void setAttachments(List<EmailAttachment> attachments) {    this.attachments = attachments;  }  public List<String> getBccAddress() {    return bccAddress;  }  public void setBccAddress(List<String> bccAddress) {    this.bccAddress = bccAddress;  }  public String getSubject() {    return subject;  }  public void setSubject(String subject) {    this.subject = subject;  }  public String getContent() {    return content;  }  public void setContent(String content) {    this.content = content;  }  public void setToAddress(List<String> toAddress) {    this.toAddress = toAddress;  }  public List<String> getCcAddress() {    return ccAddress;  }  public void setCcAddress(List<String> ccAddress) {    this.ccAddress = ccAddress;  }}

MailUtil.java:发送邮件工具类

package com.test.mail;import java.util.List;import org.apache.commons.mail.EmailAttachment;import org.apache.commons.mail.EmailException;import org.apache.commons.mail.HtmlEmail;/** * 发送邮件Util */public class MailUtil {    //邮箱  private static String mailServerHost = "smtp.163.com";  private static String mailSenderAddress = "test@163.com";  private static String mailSenderNick = "test";  private static String mailSenderUsername = "test@163.com";  private static String mailSenderPassword = "xxx";    /**   * 发送 邮件方法 (Html格式,支持附件)   *   * @return void   */  public static void sendEmail(MailInfo mailInfo) {         try {      HtmlEmail email = new HtmlEmail();      // 配置信息      email.setHostName(mailServerHost);      email.setFrom(mailSenderAddress,mailSenderNick);      email.setAuthentication(mailSenderUsername,mailSenderPassword);      email.setCharset("UTF-8");      email.setSubject(mailInfo.getSubject());      email.setHtmlMsg(mailInfo.getContent());      // 添加附件      List<EmailAttachment> attachments = mailInfo.getAttachments();      if (null != attachments && attachments.size() > 0) {        for (int i = 0; i < attachments.size(); i++) {          email.attach(attachments.get(i));        }      }            // 收件人      List<String> toAddress = mailInfo.getToAddress();      if (null != toAddress && toAddress.size() > 0) {        for (int i = 0; i < toAddress.size(); i++) {            email.addTo(toAddress.get(i));        }      }      // 抄送人      List<String> ccAddress = mailInfo.getCcAddress();      if (null != ccAddress && ccAddress.size() > 0) {        for (int i = 0; i < ccAddress.size(); i++) {            email.addCc(ccAddress.get(i));        }      }      //邮件模板 密送人      List<String> bccAddress = mailInfo.getBccAddress();      if (null != bccAddress && bccAddress.size() > 0) {        for (int i = 0; i < bccAddress.size(); i++) {          email.addBcc(ccAddress.get(i));        }      }      email.send();      System.out.println("邮件发送成功!");    } catch (EmailException e) {      e.printStackTrace();    }   }}

TestMail.java:发送邮件测试类

package com.test.mail;import java.util.ArrayList;import java.util.List;import org.apache.commons.mail.EmailAttachment;public class TestMail {  /**   * @return void   */  public static void main(String[] args) {    MailInfo mailInfo = new MailInfo();    List<String> toList = new ArrayList<String>();    toList.add("my@163.com");        List<String> ccList = new ArrayList<String>();    ccList.add("my@163.com");        List<String> bccList = new ArrayList<String>();    bccList.add("my@163.com");        //添加附件    EmailAttachment att = new EmailAttachment();    att.setPath("g:\\测试.txt");    att.setName("测试.txt");    List<EmailAttachment> atts = new ArrayList<EmailAttachment>();    atts.add(att);    mailInfo.setAttachments(atts);        mailInfo.setToAddress(toList);//收件人    mailInfo.setCcAddress(ccList);//抄送人    mailInfo.setBccAddress(bccList);//密送人        mailInfo.setSubject("测试主题");    mailInfo.setContent("内容:<h1>test,测试</h1>");         MailUtil.sendEmail(mailInfo);  }}
