我正在尝试从我的使用jhipster 1.1.0生成的spring应用程序中发送邮件,我的spring-boot版本是1.5.2。
我有以下代码:
Application-dev.yml:
最终我使用这个控制器来发送邮件。
@RequestMapping("/api")表示这个类是一个REST API的控制器,它会处理来自"/api"路径的HTTP请求。这个类名为MyClassResource。
最后我得到了这个错误:
我一直在阅读关于这个错误的内容,并像application-dev.yml中一样添加了一些配置,但这个方法不起作用。我试着从Gmail获取一个应用程序密码,因为我读到说这是必要的,但由于我没有进行双步验证,所以我无法获取该密码。最后,我改变了接受来自较不安全应用程序的连接,但仍然不起作用。我不知道为什么它不起作用。
我有以下代码:
Application-dev.yml:
spring:
mail:
host: smtp.gmail.com
port: 587
username: myuser@gmail.com
password: mypass
protocol: smtp
tls: true
properties.mail.smtp:
auth: true
starttls.enable: true
#ssl.trust: smtp.gmail.com
starttls.required: true
jhipster:
mail: # specific JHipster mail property, for standard properties see MailProperties
from: myuser@gmail.com
base-url: http://127.0.0.1:8080

LoggerFactory.getLogger(MyClassResource.class);
@Autowired
EntityManager entityManager;
@Autowired
MailService mailService;
@PostMapping ("/myurl")
@Timed
public ResponseEntity<Boolean> mymethod(@RequestBody myObject data) {
mailService.sendEmail(
"emailTo@gmail.com",
"message from spring",
"hi world. this message is from spring",
true,
true
);
}
最后我得到了这个错误:

文件中有很多内容,但如果你查看文档,键应该是spring.mail.*

没有正确缩进,必须嵌套在邮件下面,就像官方文档中所示:https://www.jhipster.tech/tips/011_tip_configuring_email_in_jhipster.html。而且 JHipster 版本很不可能是 1.1.0,因为那已经是 5 年前的版本,也不使用 Spring Boot 1.5。 - Gaël MarziouEnableSSL.enable: true
