3 . 邮件详情实体类 EmailMailInfo.java

/** * ClassName: EmailMailInfo.java <br> * Description: <br> * Create by: name：yuxin <br>email: yuruixin_china@163.com <br> * Create Time: 2017年6月15日<br> */ public class EmailMailInfo { //邮箱服务器如smtp.163.com private String host ; //用户邮箱如**@163 private String formName ; //用户授权码不是用户名密码可以自行查看相关邮件服务器怎么查看 private String formPassword ; //消息回复邮箱 private String replayAddress ; //发送地址 private String toAddress ; //发送主题 private String subject ; //发送内容 private String content ; public String getHost() { return host; } public void setHost(String host) { this.host = host; } public String getFormName() { return formName; } public void setFormName(String formName) { this.formName = formName; } public String getFormPassword() { return formPassword; } public void setFormPassword(String formPassword) { this.formPassword = formPassword; } public String getReplayAddress() { return replayAddress; } public void setReplayAddress(String replayAddress) { this.replayAddress = replayAddress; } public String getToAddress() { return toAddress; } public void setToAddress(String toAddress) { this.toAddress = toAddress; } 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; } }
