springBoot项目中如何整合javamail 群发邮件操作
第一步，在resources下建立一个mail.properties文件
mail.smtp.service=smtp.qq.com #465/587 mail.smtp.port=587 mail.from.address=你服务邮箱 mail.from.smtp.pwd=自己开启qq邮箱设置的独立密码（在邮箱-设置 下面） mail.from.nickname=随便自己怎么搞
第二步
准备几个工具类
第一个
package com.xuemeng.mail;
import java.util.Locale;
import java.util.ResourceBundle;
/**
* @author xuemeng
* @date 2018/12/13 11:29
*/
public class PropertiesUtil {
private final ResourceBundle resource;
private final String fileName;
public PropertiesUtil (String fileName) {
this.fileName = fileName;
Locale locale=new Locale("zh","CN");
this.resource=ResourceBundle.getBundle(this.fileName,locale);
}
public String getValue(String key){
String message=this.resource.getString(key);
return message;
}
}
第二个
package com.xuemeng.mail;
/**
* @author xuemeng
* @date 2018/12/13 11:38
*/
public enum MailContentTypeEnum {
HTML("text/html;charset=UTF-8"),//html格式
TEXT("text");
private String value;
MailContentTypeEnum(String value){
this.value=value;
}
public String getValue(){
return value;
}
}
第三个
package com.xuemeng.mail;
import java.io.Serializable;
import java.util.ArrayList;
import java.util.List;
/**
* @author xuemeng
* @date 2018/12/13 10:59
*/
public class MailEntity implements Serializable {
//此处填写smtp服务器
private String smtpService;
//设置端口号
private String smtpPort;
//设置发送youxiang
private String formMailAddress;
//设置发送口令
private String formMailStmpPwd;
//设置标题
private String title;
// 内容
private String content;
//格式html
private String contentType;
//收件（接受）邮箱集合
private List list=new ArrayList<>();
//省略getset方法
}
第四个
package com.xuemeng.mail;
import javax.mail.*;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeUtility;
import java.util.List;
import java.util.Properties;
/**
* @author xuemeng
* @date 2018/12/13 11:14
* pwd:qgyantrvozembeji
* //第三方登陆qq密码：qgyantrvozembeji
*/
public class MailSender {
//实例化一个mail对象
private static MailEntity mail=new MailEntity();
/**
* 设置标题
* @param title
* @return
*/
public MailSender title(String title){
mail.setTitle(title);
return this;
}
/**
* 设置邮件内容
* @param content
* @return
*/
public MailSender content(String content){
mail.setContent(content);
return this;
}
/**
* 邮件内容格式
* @param typeEnum
* @return
*/
public MailSender contentType(MailContentTypeEnum typeEnum){
mail.setContentType(typeEnum.getValue());
return this;
}
/**
* 目标邮箱
* @param targets
* @return
*/
public MailSender target(List targets){
mail.setList(targets);
return this;
}
public void send() throws Exception{
if(mail.getContentType()==null){
mail.setContentType(MailContentTypeEnum.HTML.getValue());
}
if(mail.getContent()==null||mail.getContent().trim().length()==0){
throw new Exception("请填写邮件内容");
}
if(mail.getTitle()==null||mail.getTitle().trim().length()==0){
throw new Exception("请填写邮件标题");
}
if(mail.getList().size()==0){
throw new Exception("请填写要发送的人员");
}
final PropertiesUtil putil=new PropertiesUtil("mail");
final Properties prop=new Properties();
prop.put("mail.smtp.auth",true);
/* prop.put("mail.smtp.starttls.enable", "true");
//不做服务器证书校验
prop.put("mail.smtp.ssl.checkserveridentity", "false");
//添加信任的服务器地址，多个地址之间用空格分开
prop.put("mail.smtp.ssl.trust", putil.getValue("mail.smtp.service"));*/
prop.put("mail.smtp.host",putil.getValue("mail.smtp.service"));
prop.put("mail.smtp.port",putil.getValue("mail.smtp.port"));
prop.put("mail.user",putil.getValue("mail.from.address"));
prop.put("mail.password",putil.getValue("mail.from.smtp.pwd"));
String username=prop.getProperty("mail.user");
String password=prop.getProperty("mail.password");
/* Authenticator acthenticator=new Authenticator() {
@Override
protected PasswordAuthentication getPasswordAuthentication() {
String username=prop.getProperty("mail.user");
String pawwword=prop.getProperty("mail.password");
return new PasswordAuthentication(username,pawwword);
}
};
*/
Session mailsession=Session.getInstance(prop, new Authenticator() {
@Override
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(username,password);
}
});
MimeMessage message=new MimeMessage(mailsession);
String nickname= MimeUtility.encodeText(putil.getValue("mail.from.nickname"));
InternetAddress address=new InternetAddress(nickname+"<"+prop.getProperty("mail.user")+">");
message.setFrom(address);
message.setSubject(mail.getTitle());
if(mail.getContentType().equals(MailContentTypeEnum.HTML.getValue())){
message.setContent(mail.getContent(),mail.getContentType());
}
else if(mail.getContentType().equals(MailContentTypeEnum.TEXT.getValue())){
message.setText(mail.getContent());
}
List targets=mail.getList();
for(int i=0;i
最后测试
package com.xuemeng;
import com.xuemeng.mail.MailContentTypeEnum;
import com.xuemeng.mail.MailSender;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;
import javax.xml.soap.Text;
import java.util.ArrayList;
import java.util.List;
@RunWith(SpringRunner.class)
@SpringBootTest
public class ManagerApplicationTests {
@Test
public void contextLoads() {
/**
* 测试发送email
*/
MailSender sender=new MailSender();
sender.title("测试邮件发送");
sender.content("简单文本发送");
sender.contentType(MailContentTypeEnum.TEXT);
List list=new ArrayList<>();
list.add("[email protected]");
list.add("[email protected]");
list.add("[email protected]");
sender.target(list);
try{
sender.send();
}catch (Exception e){
e.printStackTrace();
}
}
}
常见的问题
javax.mail.AuthenticationFailedException: 454 Authentication failed, please open smtp flag first!我用的是QQ邮箱，需要开启POP3/SMTP服务。
com.sun.mail.smtp.SMTPSendFailedException: 503 Error: need EHLO and AUTH first !需要验证，设置mail.smtp.auth为true。javax.mail.AuthenticationFailedException: 535 Authentication failed是QQ邮箱开头pop/smtp服务需要独立密码，就是你开启服务系统给的密码
com.sun.mail.smtp.SMTPSenderFailedException: 553 Envolope sender mismatch with login user验证的用户和发送者要一致
