Android 使用 JavaMail

今天學習了一下JavaMail,javamail發送郵件確實是一個比較麻煩的問題不用第三方郵件程序。爲了之後使用方便,本身寫了段代碼.html

Javamail-Android配置步驟:java

  1. 下載Android版本JavaMail包,additional.jar、mail.jar和activation.jar,下載地址JavaMail-Androidandroid

  2. 在項目與src同一目錄級別下,新建文件夾lib,將下載的3個jar包放入該文件夾服務器

  3. 右鍵->Properties->Java Build Path->Libraries,選擇Add External JARs,找到項目下lib目錄的3個jar包網絡


個人代碼有三個類:  
第一個類:MailSenderInfo.javasession

package com.util.mail;
/** 
* 發送郵件須要使用的基本信息 
*/ 
import java.util.Properties; 
public class MailSenderInfo { 
	// 發送郵件的服務器的IP和端口 
	private String mailServerHost; 
	private String mailServerPort = "25"; 
	// 郵件發送者的地址 
	private String fromAddress; 
	// 郵件接收者的地址 
	private String toAddress; 
	// 登錄郵件發送服務器的用戶名和密碼 
	private String userName; 
	private String password; 
	// 是否須要身份驗證 
	private boolean validate = false; 
	// 郵件主題 
	private String subject; 
	// 郵件的文本內容 
	private String content; 
	// 郵件附件的文件名 
	private String[] attachFileNames; 	
	/** 
	  * 得到郵件會話屬性 
	  */ 
	public Properties getProperties(){ 
	  Properties p = new Properties(); 
	  p.put("mail.smtp.host", this.mailServerHost); 
	  p.put("mail.smtp.port", this.mailServerPort); 
	  p.put("mail.smtp.auth", validate ? "true" : "false"); 
	  return p; 
	} 
	public String getMailServerHost() { 
	  return mailServerHost; 
	} 
	public void setMailServerHost(String mailServerHost) { 
	  this.mailServerHost = mailServerHost; 
	}
	public String getMailServerPort() { 
	  return mailServerPort; 
	}
	public void setMailServerPort(String mailServerPort) { 
	  this.mailServerPort = mailServerPort; 
	}
	public boolean isValidate() { 
	  return validate; 
	}
	public void setValidate(boolean validate) { 
	  this.validate = validate; 
	}
	public String[] getAttachFileNames() { 
	  return attachFileNames; 
	}
	public void setAttachFileNames(String[] fileNames) { 
	  this.attachFileNames = fileNames; 
	}
	public String getFromAddress() { 
	  return fromAddress; 
	} 
	public void setFromAddress(String fromAddress) { 
	  this.fromAddress = fromAddress; 
	}
	public String getPassword() { 
	  return password; 
	}
	public void setPassword(String password) { 
	  this.password = password; 
	}
	public String getToAddress() { 
	  return toAddress; 
	} 
	public void setToAddress(String toAddress) { 
	  this.toAddress = toAddress; 
	} 
	public String getUserName() { 
	  return userName; 
	}
	public void setUserName(String userName) { 
	  this.userName = userName; 
	}
	public String getSubject() { 
	  return subject; 
	}
	public void setSubject(String subject) { 
	  this.subject = subject; 
	}
	public String getContent() { 
	  return content; 
	}
	public void setContent(String textContent) { 
	  this.content = textContent; 
	} 
}

第二個類:MultiMailsender.java

          // 判斷是否須要身份認證 
          MyAuthenticator authenticator = null; 
          Properties pro = mailInfo.getProperties();
          if (mailInfo.isValidate()) { 
          // 若是須要身份認證,則建立一個密碼驗證器

        return false;
    }
    
    /**

            this.ccs = ccs;

            return receivers;
        }
        public void setReceivers(String[] receivers) {
            this.receivers = receivers;
        }
    }
}

第三個類:MyAuthenticator.java

package com.util.mail;
 
import javax.mail.*;
   
public class MyAuthenticator extends Authenticator{
    String userName=null;
    String password=null;
      
    public MyAuthenticator(){
    }
    public MyAuthenticator(String username, String password) { 
        this.userName = username; 
        this.password = password; 
    } 
    protected PasswordAuthentication getPasswordAuthentication(){
        return new PasswordAuthentication(userName, password);
    }
}

下面給出使用上面三個類的代碼:

public static void main(String[] args){
         //這個類主要是設置郵件
      MultiMailSenderInfo mailInfo = new MultiMailSenderInfo(); 
      mailInfo.setMailServerHost("smtp.163.com"); 
      mailInfo.setMailServerPort("25"); 
      mailInfo.setValidate(true); 
      mailInfo.setUserName("xxx@163.com"); 
      mailInfo.setPassword("**********");//您的郵箱密碼 
      mailInfo.setFromAddress("xxx@163.com"); 
      mailInfo.setToAddress("xxx@163.com"); 
      mailInfo.setSubject("設置郵箱標題"); 
      mailInfo.setContent("設置郵箱內容");
      String[] receivers = new String[]{"***@163.com", "***@tom.com"}; 
      String[] ccs = receivers; mailInfo.setReceivers(receivers); 
      mailInfo.setCcs(ccs); 
      //這個類主要來發送郵件 
      MultiMailsender sms = new MultiMailsender(); 
      sms.sendTextMail(mailInfo);//發送文體格式 
      MultiMailsender.sendHtmlMail(mailInfo);//發送html格式 
      MultiMailsender.sendMailtoMultiCC(mailInfo);//發送抄送

最後,給出朋友們幾個注意的地方:  
一、使用此代碼你能夠完成你的javamail的郵件發送功能、發多個郵箱。三個類缺一不可。  
二、這三個類我打包是用的com.util.mail包,若是不喜歡,你能夠本身改,但三個類文件必須在同一個包中  
三、不要使用你剛剛註冊過的郵箱在程序中發郵件,若是你的163郵箱是剛註冊不久,那你就不要使用「smtp.163.com」。由於你發不出去。剛註冊的郵箱是不會給你這種權限的,也就是你不能經過驗證。要使用你常常用的郵箱,並且時間比較長的。  
四、另外一個問題就是mailInfo.setMailServerHost("smtp.163.com");mailInfo.setFromAddress("xxx@163.com");這兩句話。即若是你使用163smtp服務器,那麼發送郵件地址就必須用163的郵箱,若是不的話,是不會發送成功的。  
五、關於javamail驗證錯誤的問題,網上的解釋有不少,但我看見的只有一個。就是個人第三個類。你只要複製全了代碼,我想是不會有問題的。學習

六、 而後在Android項目中添加網絡訪問權限ui

<uses-permission android:name="android.permission.INTERNET"></uses-permission>this
