Android 使用 JavaMail

今天学习了一下JavaMail，javamail发送邮件确实是一个比较麻烦的问题不用第三方邮件程序。为了以后使用方便，自己写了段代码.

Javamail-Android配置步骤：

下载Android版本JavaMail包，additional.jar、mail.jar和activation.jar，下载地址JavaMail-Android

在项目与src同一目录级别下，新建文件夹lib，将下载的3个jar包放入该文件夹

右键->Properties->Java Build Path->Libraries，选择Add External JARs，找到项目下lib目录的3个jar包

我的代码有三个类：
第一个类：MailSenderInfo.java

01
package com.util.mail;
02
/**
03
* 发送邮件需要使用的基本信息
04
*/
05
import java.util.Properties;
06
public class MailSenderInfo {
07
    // 发送邮件的服务器的IP和端口
08
    private String mailServerHost;
09
    private String mailServerPort = "25";
10
    // 邮件发送者的地址
11
    private String fromAddress;
12
    // 邮件接收者的地址
13
    private String toAddress;
14
    // 登陆邮件发送服务器的用户名和密码
15
    private String userName;
16
    private String password;
17
    // 是否需要身份验证
18
    private boolean validate = false;
19
    // 邮件主题
20
    private String subject;
21
    // 邮件的文本内容
22
    private String content;
23
    // 邮件附件的文件名
24
    private String[] attachFileNames;
25
    /**
26
      * 获得邮件会话属性
27
      */
28
    public Properties getProperties(){
29
      Properties p = new Properties();
30
      p.put("mail.smtp.host", this.mailServerHost);
31
      p.put("mail.smtp.port", this.mailServerPort);
32
      p.put("mail.smtp.auth", validate ? "true" : "false");
33
      return p;
34
    }
35
    public String getMailServerHost() {
36
      return mailServerHost;
37
    }
38
    public void setMailServerHost(String mailServerHost) {
39
      this.mailServerHost = mailServerHost;
40
    }
41
    public String getMailServerPort() {
42
      return mailServerPort;
43
    }
44
    public void setMailServerPort(String mailServerPort) {
45
      this.mailServerPort = mailServerPort;
46
    }
47
    public boolean isValidate() {
48
      return validate;
49
    }
50
    public void setValidate(boolean validate) {
51
      this.validate = validate;
52
    }
53
    public String[] getAttachFileNames() {
54
      return attachFileNames;
55
    }
56
    public void setAttachFileNames(String[] fileNames) {
57
      this.attachFileNames = fileNames;
58
    }
59
    public String getFromAddress() {
60
      return fromAddress;
61
    }
62
    public void setFromAddress(String fromAddress) {
63
      this.fromAddress = fromAddress;
64
    }
65
    public String getPassword() {
66
      return password;
67
    }
68
    public void setPassword(String password) {
69
      this.password = password;
70
    }
71
    public String getToAddress() {
72
      return toAddress;
73
    }
74
    public void setToAddress(String toAddress) {
75
      this.toAddress = toAddress;
76
    }
77
    public String getUserName() {
78
      return userName;
79
    }
80
    public void setUserName(String userName) {
81
      this.userName = userName;
82
    }
83
    public String getSubject() {
84
      return subject;
85
    }
86
    public void setSubject(String subject) {
87
      this.subject = subject;
88
    }
89
    public String getContent() {
90
      return content;
91
    }
92
    public void setContent(String textContent) {
93
      this.content = textContent;
94
    }
95
}
第二个类：MultiMailsender.java
001
package com.util.mail;
002

003
import java.util.Date;
004
import java.util.Properties;
005

006
import javax.mail.Address;
007
import javax.mail.BodyPart;
008
import javax.mail.Message;
009
import javax.mail.MessagingException;
010
import javax.mail.Multipart;
011
import javax.mail.Session;
012
import javax.mail.Transport;
013
import javax.mail.internet.InternetAddress;
014
import javax.mail.internet.MimeBodyPart;
015
import javax.mail.internet.MimeMessage;
016
import javax.mail.internet.MimeMultipart;
017

018
/**
019
* 发送邮件给多个接收者、抄送邮件
020
*/
021
public class MultiMailsender {
022

023

024
    /**
025
      * 以文本格式发送邮件
026
      * @param mailInfo 待发送的邮件的信息
027
      */
028
        public boolean sendTextMail(MultiMailSenderInfo mailInfo) {
029
          // 判断是否需要身份认证
030
          MyAuthenticator authenticator = null;
031
          Properties pro = mailInfo.getProperties();
032
          if (mailInfo.isValidate()) {
033
