java mail 发送邮件

1. 邮件发送封装类

import java.util.Properties;

/**
 * @ClassName: MailInfo
 * @Description: 发送邮件需要使用的基本信息
 * 
 */
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;
    }
}

 

2. 邮件验证器

import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;

/**
 * @ClassName: MyAuthenticator
 * @Description: 邮箱验证器
 */
public class MyAuthenticator extends Authenticator {
    /**
     * 邮箱服务器用户名
     */
    String userName = null;

    /**
     * 邮箱服务器密码
     */
    String password = null;

    public AppocAuthenticator() {
    }

    public AppocAuthenticator(String username, String password) {
        this.userName = username;
        this.password = password;
    }

    protected PasswordAuthentication getPasswordAuthentication() {
        return new PasswordAuthentication(userName, password);
    }
}
