我有一个使用 Gradle 依赖项用 Spring Boot 编写的简单示例应用程序。它在调用 localhost:8080/greetings 时显示 helloworld。我将它打包为 WAR 并将其作为 myWebApp.war 部署到 Tomcat。

当我调用 localhost:8080/myWebApp/greetings 时，我得到 404。我应该从下面的 catalina.log 中推断出什么

要在独立的 servlet 容器中运行 Spring Boot 应用程序，您需要告诉容器如何启动应用程序。您可以通过扩展SpringBootServletInitializer和覆盖该configure方法来为您的应用程序提供配置类来做到这一点。这在将 jar 转换为 war 的入门指南中进行了描述。

你通常会得到这样的类：

@Configuration
@EnableAutoConfiguration
public class Application extends SpringBootServletInitializer {

    // Used when launching as an executable jar or war
    public static void main(String[] args) throws Exception {
        SpringApplication.run(Application.class, args);
    }

    // Used when deploying to a standalone servlet container
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Application.class);
    }
}
