使用tomcat和cxf-servlet进行spring-boot

Question

我试图用弹簧启动来构建一个嵌入式Tomcat.我想在应用程序中使用CXF作为一组Web服务,但我无法弄清楚如何站起来使用CXF servlet.

我的主要课程看起来像这样......

@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并启动jar时 ./gradlew build && java -jar build/libs/gs-spring-boot-0.1.0.jar

我得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的回答类似,我可以通过删除ServletContextInitializer并将bean添加到Application Class来解决它.

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

春季启动嵌入式servlet的功能设计工作,并具Servlet和ServletRegistration @Beans,而不是与ContextLoaderListener(这看起来是试图窃取ServletContext根上下文属性).尝试ServletRegistration为您的servlet 添加一个; 如果它是Spring知道的,假设它有一个允许你更改应用程序上下文或上下文位置的接口,那么你应该能够在注册中配置它.
