首先加代码配置文件来一个
mail.properties
mail.smtp.host=mail.smtp.port=465mail.smtp.SSLport=587mail.smtp.starttlsEnable=truemail.smtp.auth=truemail.smtp.account=11036128@mail.smtp.password=qrqzbcfslyhaaimail.smtp.timeout=50000mail.smtp.connectiontimeout=50000mail.smtp.nickname=ewe
我使用的是腾讯qq邮箱
首先要去腾讯qq的设置===》账户》》开通授权码，第三方登陆需要授权码当成密码使用
然后在springboot引入这个配置文件

测试可用
依赖maven加的是
<!-- email --><dependency><groupId>com.sun.mail</groupId><artifactId>javax.mail</artifactId><version>1.5.4</version></dependency>
里面的一些port 是不加密 SSLport是加密的
