java發送郵件帶url、html

創建一個密碼驗證器類

package com.mail.test;
 
import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;
 
public class MailAuthenticator extends Authenticator {
	
	public MailAuthenticator(String userName,String userPwd){
		this.userAccout = userName;
		this.userPassword = userPwd;
	}
	
	private String userAccout;
	private String userPassword;
	public String getUserAccout() {
		return userAccout;
	}
	public void setUserAccout(String userAccout) {
		this.userAccout = userAccout;
	}
	public String getUserPassword() {
		return userPassword;
	}
	public void setUserPassword(String userPassword) {
		this.userPassword = userPassword;
	}
	
	
	@Override
	protected PasswordAuthentication getPasswordAuthentication() {
		// TODO Auto-generated method stub
		return new PasswordAuthentication(userAccout, userPassword);
	}
}

組織發送內容，包含url、html，測試發送： 
package com.mail.test;
 
import java.io.UnsupportedEncodingException;
import java.net.URLEncoder;
 
public class MailTest {
 
	public static void main(String[] args) {
		try {
			MailSender sender  = new MailSender();
			MainInfo mainInfo = new MainInfo();
			mainInfo.setMailServerHost("smtp.163.com");  //imap.exmail.qq.com
			mainInfo.setMailServerPort("25");
			mainInfo.setUserName("煩煩煩");
			mainInfo.setFromAddress("*******");
			mainInfo.setPassword("*******");
			mainInfo.setToAddress("*******");
			mainInfo.setSubject("測試內容標題");
			StringBuffer url = new StringBuffer();
			url.append("http://locahost:8080");
			url.append("noa");
			url.append("/reportFindPassword/updatePassword.action?");
			url.append("employeeCode=123456");
			url.append("&employeeName="+URLEncoder.encode("發送郵件測試", "UTF-8"));
			url.append("&pemployeeCode=123456");
			url.append("&pemployeeName="+URLEncoder.encode("哈哈", "UTF-8"));
			url.append("&email=*******@***.com");
			url.append("&dateTime=20160418162538");
			StringBuffer content = new StringBuffer();

			content.append("<p style='color:red;'>");
			content.append("啊啊啊(123456)您好：</p>");
			content.append("<p style='text-indent: 2em;'>您正在使用密碼找回功能，請點擊下面的鏈接完成密碼找回。</p>");

			content.append("<ul style='color: rgb(169, 169, 189);font-size: 18px;'>");
			content.append("<li>爲了保障您帳號的安全，該鏈接有效期爲12小時。</li>");
			content.append("<li>該鏈接只能使用一次，請周知。</li>");

其中鏈接中包含的中文做URL轉碼，
最後的郵件爲：



此類郵件URL需要做校驗，如果鏈接中只包含一個標示，則只對當前標示加密，如果所有參數都暴露在地址欄中可以將所有參數拼起來用MD5或者其他方式加密後存放在該URL中，例如爲validateCode，此次也要對validateCode的值做encode轉換，不然特殊符號在URL中會自動轉換，之後只對validateCode校驗即可知道該鏈接是否正確。
