我试图用spring-boot支撑嵌入式Tomcat。我想在应用程序中将CXF用于一组Web服务，但是我不知道如何站立CXF Servlet。

我的主班看起来像这样…

@Configuration
@EnableAutoConfiguration
@ComponentScan(basePackages={"com.connecture.services.documentservice.webservice"})
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(new Class[] { Application.class, CfxInitializer.class }, args);
    }

    @Bean
  public EmbeddedServletContainerFactory embeddedServletContainerFactory() {
      TomcatEmbeddedServletContainerFactory factory = new TomcatEmbeddedServletContainerFactory("", 8080);
      return factory;
  }

}

我的CfxInitializer就像这样…

public class CfxInitializer implements ServletContextInitializer
{

  @Override
  public void onStartup(ServletContext servletContext) throws ServletException
  {
    XmlWebApplicationContext rootContext = new XmlWebApplicationContext();  
    rootContext.setConfigLocations(new String[] { "classpath*:applicationContext.xml" });  
    servletContext.addListener(new ContextLoaderListener(rootContext));

    ServletRegistration.Dynamic dispatcher = servletContext.addServlet("CXFServlet", CXFServlet.class);  
    dispatcher.addMapping("/api/*");  
  }

}

当我尝试使用典型命令构建和启动jar时 ./gradlew build && java -jar build/libs/gs-spring- boot-0.1.0.jar

我收到多个上下文的异常。

Java.lang.IllegalStateException: Cannot initialize context because there is already a root application context present - check whether you have multiple ContextLoader* definitions in your web.xml!

与Dave的答案类似，我可以通过删除ServletContextInitializer并将一个bean添加到Application Class来修复它。

@Bean
  public ServletRegistrationBean servletRegistrationBean(){
      return new ServletRegistrationBean(new CXFServlet(),"/api/*");
  }
