我要评论序
本文展示一下如何使用spring mail来发送html邮件。
maven
<!-- email -->
<dependency>
<groupid>org.springframework.boot</groupid>
<artifactid>spring-boot-starter-mail</artifactid>
</dependency>
发送图片
public void send(string from, string[] tomails, string subject, string text,
map<string,object> inlines) throws exception{
mimemessage mimemessage = mailsender.createmimemessage();
mimemessagehelper helper = new mimemessagehelper(mimemessage, true);
helper.setfrom(from);
helper.setto(tomails);
helper.setsubject(subject);
helper.settext(text, true); //支持html
// 增加inline
if(inlines != null){
for(map.entry<string,object> entry: inlines.entryset()){
if(entry.getvalue() instanceof classpathresource){
helper.addinline(entry.getkey(), (resource) entry.getvalue());
}
}
}
mailsender.send(mimemessage);
}
测试
发送实例
classpathresource classpathresource = new classpathresource("image_2.png");
map<string,object> att = new hashmap<>();
att.put("image",classpathresource);
string content = "<html>
<body>
<h4>spring mail发送实例</h4>
<img src='cid:image'/><br>
</body>
</html>";
try{
mailservice.send(new string[]{"xxxxx@163.com"},"spring mail发送实例",content,att);
}catch (exception e){
e.printstacktrace();
}
异常

错误码554
554 dt:spm 发送的邮件内容包含了未被许可的信息，或被系统识别为垃圾邮件。请检查是否有用户发送病毒或者垃圾邮件；
被网易邮箱识别为垃圾邮件了，有个歪招，就是把发送邮箱添加到cc里头
helper.setcc(from);
