Solutions and attention:
Pay attention to whether the account of the receiver or sender in the configuration or custom is correct
//Sender private String from="xxxxxxxxqq.com"; //Receiver private String to="xxxxxxxqq.com";
spring:
mail:
host: smtp.qq.com
username: [email protected]
password: ****************
①Is it correct to accept the email account (I made a mistake in the qq account here);
message.setTo(to);
②Is the sender address correct
message.setFrom(from);
