我是Spring Boot的新手，尝试使用spring初始值设定项在intellij中构建我的第一个Spring Boot项目（Maven）时，在创建项目后运行项目时出现此错误：

无法访问org.springframework.context.ConfigurableApplicationContext的org.springframework.context.ConfigurableApplicationContext类文件

我遵循了许多教程，但是每次遇到此错误时，如何解决此问题？

我的pom.xml文件：

我想在 Spring Boot 中使用JavaMailSender. 每当我运行我的项目时，我都会收到此错误：

org.springframework.mail.MailSendException：失败的消息：com.sun.mail.smtp.SMTPSendFailedException：530-5.5.1 需要身份验证。在 530 5.5.1 https://support.google.com/mail/answer/14257 ps2sm10628859pab.10 - gsmtp了解更多 信息

我没有为我的帐户使用两步验证，密码也正确，我检查过。

这是我的 application.properties 文件：

spring.mail.host = smtp.gmail.com
sprint.mail.username = apptestacc1234@gmail.com
sprint.mail.password = *******
send.from.email= apptestacc1234@gmail.com
spring.mail.properties.mail.smtp.auth = true;
spring.mail.properties.mail.smtp.starttls.enable = true
spring.mail.properties.mail.smtp.ssl.enable = true
spring.mail.properties.mail.socketFactory.port=587
spring.mail.properties.mail.socketFactory.class=javax.net.ssl.SSLSocketFactory
spring.mail.properties.mail.socketFactory.fallback=false
spring.mail.smtp.port= 587

我的邮件服务类：

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.mail.MailException;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.stereotype.Component;

@Component

//public MailService(JavaMailSender javaMailSender){
