java - 未能实例化 WebApplicationInitializer - Tomcat 启动

标签 java spring-boot tomcat

我在 TomCat 9 上启动我的 Spring Boot 应用程序时遇到问题。 在 Intellij IDE 中，应用程序启动并按预期工作。

当我尝试通过 TomCat Web 应用程序管理器启动应用程序时，我收到消息:

失败 - 上下文路径 [/bedelServer-0.0.1-SNAPSHOT] 中的应用程序无法启动

是不是和我主类的构造函数有关？

最佳答案 

@Autowired
private ConfigClass config;

删除

public BwsApplication (ConfigClass configClass) {
    config = configClass;
}
