[转载]JavaMail 发送邮件

做了一个小小的程序, 来进行通过 163.com 发送邮件的工作:

Java代码

1. import java.util.*;

14. private String from;
15. /** 收信人 */
16. private String to;
17. /** 主题 */
18. private String subject;
19. /** 正文 */
20. private String body;
22. private static Properties props = new Properties();
23. static {
24. try {
25. InputStream in = MailSender.class
26. .getResourceAsStream("MailSender.ini");
27. props.load(in);
28. in.close();
29. } catch (Exception ex) {
30. System.err.println("无法加载配置文件 MailSender.ini:" + ex.getMessage());

42. public boolean sendMail() {
43. if (getBody() == null || getTo() == null || getFrom() == null
44. || getSubject() == null) { return false; }
45. //--[ Obtain a session

54. Session mailSession = Session.getDefaultInstance(props);
55. Message msg = new MimeMessage(mailSession);
57. //--[ Set the FROM, TO, DATE and SUBJECT fields
58. msg.setFrom(new InternetAddress(getFrom()));
59. msg.addRecipients(Message.RecipientType.TO, InternetAddress
60. .parse(getTo()));
61. msg.setSentDate(new Date());
62. msg.setSubject(getSubject());
64. //--[ Create the body of the mail

66. msg.saveChanges();
67. // Using the mail authentication, transport.connect(host, user, password)
68. Transport transport = mailSession.getTransport("smtp");
69. transport.connect(props.getProperty("mail.smtp.host"), props
70. .getProperty("username"), props.getProperty("password"));
72. transport.sendMessage(msg, msg.getAllRecipients());
73. transport.close();
75. // System.out.println("The email below was sent successfully");
76. } catch (Exception e) {
77. System.out.println(e);
78. // e.printStackTrace();
79. return false;
80. }
81. return true;
82. }
84. /**
85. * @return Returns the body.
86. */
87. public String getBody() {
88. return body;
89. }
91. /**
92. * @param body
93. * The body to set.
94. */

102. public String getFrom() {
103. return from;
104. }
106. /**

108. * The from to set.
109. */
110. public void setFrom(String from) {
111. this.from = from;
112. }
114. /**

116. */
117. public String getSubject() {
118. return subject;
119. }
121. /**
122. * @param subject
123. * The subject to set.
124. */
125. public void setSubject(String subject) {
126. this.subject = subject;
127. }
129. /**
130. * @return Returns the to.
131. */
132. public String getTo() {
133. return to;
134. }
136. /**
137. * @param to
138. * The to to set.
139. */
140. public void setTo(String to) {
141. this.to = to;
142. }
144. public static void main(String[] args) {
145. MailSender sender = new MailSender();
147. sender.setFrom("admin@mxl.name");
148. sender.setTo("130105521@qq.com");
149. sender.setSubject("测试邮件-temp");
150. sender.setBody("测试邮件发送成功!");
151. System.out.println(sender.sendMail());
152. }
153. }

配置文件名称为 MailSender.ini, 和类文件放在同一目录下(同一包里), 内容如下:

Java代码

1. # SMTP 主机地址
2. mail.smtp.host = smtp.163.com
3. # SMTP 帐号用户名
4. username = mailuser
5. # SMTP 帐号密码
6. password = mailpassword
8. mail.transport.protocol = smtp
9. mail.smtp.port = 25
10. mail.smtp.auth = true

最后一行指定 SMTP 需要验证.

修改这个配置文件为实际的帐号, 然后运行 java MailSender, 即可发送邮件.

注：需要mail.jar 和 activation.jar 支持！

本程序已经过QQ、163、新浪、googleMail测试成功！
