目前，我發展與Spring MVC和春天啓動的Web應用程序。的Apache Tomcat，javax.servlet.ServletException：我的班級是不是一個Servlet
我試圖打包彈簧啓動應用程序的戰爭。我修改了應用類：
@SpringBootApplication
@ComponentScan
@EnableAutoConfiguration
public class AuditConfigurationApplication extends SpringBootServletInitializer {
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(AuditConfigurationApplication.class);
}
public static void main(String[] args) {
SpringApplication.run(AuditConfigurationApplication.class, args);
}

-My控制器休息：
package com.SSC.Services.REST;
@CrossOrigin
@RestController
@RequestMapping("/Employees")
public class UtilisateursRestController {
@RequestMapping(value="/ALL", method=RequestMethod.GET)
public List<Users> AllUsers(){
return UM.listeT();
}
}
- web.xml中
version="3.1"：
<!-- ====================================================== --> <!-- 2. Define servlet with private context --> <!-- ===================================================== --> <servlet> <servlet-name>audit</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <!-- ===================================================== --> <!-- One servlet, the audit, to rule it all --> <!-- ===================================================== --> <servlet-mapping> <servlet-name>audit</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <servlet> <servlet-name>Users</servlet-name> <servlet-class>com.SSC.Services.REST.UtilisateursRestController</servlet-class> </servlet> <servlet-mapping> <servlet-name>Users</servlet-name> <url-pattern>/Employees/*</url-pattern> //URL of controller REST </servlet-mapping> <error-page> <error-code>404</error-code> <location>/404</location> </error-page>
-audit-servlet.xml中：
<beans>
<!-- register controller in servlet private context -->
<context:component-scan base-package="com.SSC.Services.REST"/>
</beans>
-I導出我的項目 「應用程序」 戰爭文件到 「C：\ Apache的Tomcat的8.5.15 \的webapps \」。 Tomcat的創建文件夾 「應用程序」，它包含了一切：
Apps
--META-INF
-maven
-MANIFEST.MF
-war-tracker
--WEB-INF
-classes
-com
-static
-application.properties
- lib-provided
-lib
- web.xml + audit-servlet.xml
--org
-- My JSP pages ..
當我訪問API REST：http://95.x.x.x/Apps(Name of floder)/Employees/ALL，我有這樣的錯誤消息：
javax.servlet.ServletException：類[com.SSC .Services.REST.UtilisateursRestController]不是Servlet Apache Tomcat/8.5.15
如何解決這個問題？
謝謝
UtilisateursRestController不是一個servlet。你試圖將一個控制器映射到一個servlet，它會拋出異常。 – VNT
感謝您的解釋，但如何解決這個問題@VNT？如何確保訪問我的REST API？ – Michael1
刪除'web.xml'，並請閱讀很好的文檔[關於如何創建可部署戰爭的部分]（https://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#howto -create-a-deployable-war-file）的參考指南（您的依賴關係在這方面有點混亂）。 –
