Spring Boot 不尊重 @WebServlet [英] Spring Boot does not honor @WebServlet

问题描述

我创建了一个 Servlet(从 HttpServlet 扩展)并按照 3.0 规范进行了注释

I created a Servlet (extending from HttpServlet) and annotated as per 3.0 specs with

@WebServlet(name="DelegateServiceExporter", urlPatterns={"/remoting/DelegateService"})

我在 Spring Boot 中的 @Configuration 类会扫描这个 servlet 的包.但是，当我的 Spring Boot 应用程序启动时，它没有记录它已经在嵌入式 Tomcat 8.0.15 容器中部署了这个 servlet.

My @Configuration class in Spring Boot scans this servlet's package. However, it does not log that it has deployed this servlet in the embedded Tomcat 8.0.15 container when my Spring Boot application starts up.

因此，我也将 @Component 添加到了我的 servlet.现在，Spring Boot 注册 servlet(向我证明扫描包已正确设置)，但随后它使用基于类名的 URL 模式使用驼峰式大小写注册它.所以，这更好 - 例如，我注册了一个 servlet，但 URL 映射错误！

So, I added @Component to my servlet as well. Now, Spring Boot registers the servlet (proving to me that the scan package was correctly set up), but then it registers it with a URL pattern based on a class name using camel case. So, that was better - e.g., I got a servlet registered, but with the wrong URL mappings!

2015-01-05 11:29:08,516 INFO  (localhost-startStop-1) [org.springframework.boot.context.embedded.ServletRegistrationBean] Mapping servlet: 'delegateServiceExporterServlet' to [/delegateServiceExporterServlet/]

如何让 Spring Boot 自动加载所有带有 @WebServlet 注释的 servlet 并遵守它们的 url 映射?

How do I get Spring Boot to auto-load all @WebServlet annotated servlets and honor their url mappings?

推荐答案

在引导类中添加 @ServletComponentScan.

比如

@SpringBootApplication
@ServletComponentScan 
public class Application {
   public static void main(String[] args) {
       SpringApplication.run(Application.class, args);
   }
}

这将使 Spring Boot 能够扫描 @WebServlet 以及 @WebListener.

This will enable spring boot to scan @WebServlet as well as @WebListener.
