第三个类:MailAuthenticator .java
package com.mail.util;
import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;
public class MailAuthenticator extends Authenticator {
/**
* 用户名(登录邮箱)
*/
private String username;

public MailAuthenticator(String username, String password) {
this.username = username;
this.password = password;
}
String getPassword() {
return password;
}
@Override
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(username, password);
}
String getUsername() {
return username;
}
public void setPassword(String password) {
this.password = password;
}
public void setUsername(String username) {
this.username = username;
}
}
测试类
package com.mail.util;
public class MailTest {
public static void main(String[] args){
//这个类主要是设置邮件
MailSenderInfo mailInfo = new MailSenderInfo();
/*mailInfo.setMailServerHost("smtp.qiye.163.com");
mailInfo.setMailServerPort("25");
mailInfo.setValidate(true);
mailInfo.setUserName("[email protected]");
mailInfo.setPassword("mima");//您的邮箱密码
mailInfo.setFromAddress("[email protected]"); */
mailInfo.setToAddress("[email protected]");
mailInfo.setSubject("设置邮箱标题");
mailInfo.setContent("<a href='http://www.baidu.com'>设置邮箱内容</a>");
//这个类主要来发送邮件
SimpleMailSender sms = new SimpleMailSender();
// sms.sendTextMail(mailInfo);//发送文体格式
sms.sendHtmlMail(mailInfo);//发送html格式
System.out.println("发送成功");
}
}
注意问题
1.java发送邮件的完整代码,同一个包下的类,缺一不可
2.使用javamail需要导入mail.jar包
3.另一个问题就是mailInfo.setMailServerHost("smtp.163.com");与mailInfo.setFromAddress("[email protected]");这两句话。即如果你使用163smtp服务器,那么发送邮件地址就必须用163的邮箱,如果不的话,是不会发送成功的。
4.发送邮件的服务器设置,163普通用户的为mailInfo.setMailServerHost("smtp.163.com");163企业用户的为mailInfo.setMailServerHost("smtp.qiye.163.com")-----------qq的需要在设置里面的用户中设置服务器的类型 mailInfo.setMailServerHost("smtp.qq.com")才能生效
