java - 无法启动 Spring Boot 应用程序

Question

无法启动应用程序。每次我在控制台上看到这个。

2019-10-16 16:00:32.557 INFO 3496 --- [ restartedMain] com.zaxxer.hikari.HikariDataSource : HikariPool-1 - Shutdown completed.

2019-10-16 16:00:32.566 INFO 3496 --- [ restartedMain] o.apache.catalina.core.StandardService : Stopping service [Tomcat]

到目前为止，我没有收到任何错误，我在控制台上看到的是 Stopping service [Tomcat] 。我尝试了很多次，甚至改变了我的工作目录。但没有运气。即使我更改了端口号，但我没有看到任何进展。您能帮我解决一下吗？

我的 pom.xml 文件如下:

Answer 1

基于这行日志:

创建名称为“securityConfiguration”的 bean 时出错:通过字段“userService”表达的依赖关系不满足；嵌套异常是 org.springframework.beans.factory.NoSuchBeanDefinitionException:没有“com.app.dash.service.UsersService”类型的合格 bean 可用:预计至少有 1 个有资格作为 Autowiring 候选者的 bean。依赖注释:{@org.springframework.beans.factory.annotation.Autowired(required=true)}

缺少 UserServive 接口(interface)的实现。
