JAVA发送邮件和获取客户端真实ip地址

发送邮件需要使用的基本信息类MailSenderInfo 

package com.util.mail;  /**  * 发送邮件需要使用的基本信息  */   import java.util.Properties;   public class MailSenderInfo {       // 发送邮件的服务器的IP和端口       private String mailServerHost;      private String mailServerPort = "25";       // 邮件发送者的地址       private String fromAddress;       // 邮件接收者的地址       private String toAddress;       // 登陆邮件发送服务器的用户名和密码       private String userName;       private String password;       // 是否需要身份验证       private boolean validate = false;      // 邮件主题       private String subject;       // 邮件的文本内容       private String content;       // 邮件附件的文件名      private String[] attachFileNames;         /**        * 获得邮件会话属性        */       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;      }   } 

设置邮件信息MyAuthenticator

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);      }  }
