Gradle Spring Boot项目无法在Tomcat中作为WAR工作

我有一个使用Gradle依赖关系用Spring Boot编写的简单示例应用程序。它在呼叫localhost：8080 /

greetings时显示helloworld。我将其打包为WAR，并将其作为myWebApp.war部署到Tomcat。

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

  Sep 17, 2014 1:43:09 AM org.apache.catalina.core.StandardEngine startInternal

回答：

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。为此，您可以扩展SpringBootServletInitializer和覆盖此configure方法以为您的应用程序提供配置类。在将jar转换为战争的入门指南中对此进行了描述。

您通常以这样的类结束：

@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);
    }
}
