使用tomcat和cxf-servlet进行春季引导 [英] spring-boot with tomcat and cxf-servlet
问题描述
我正在尝试使用spring-boot来支撑嵌入式Tomcat。我想在应用程序中为一组Web服务使用CXF,但是我不知道如何站起CXF Servlet。
I'm trying to stand up an embedded Tomcat with spring-boot. I want to use CXF for a set of web services in the app but I can not figure out how to stand up the CXF servlet.
我的Main类如下所示……
My Main class looks like this...
@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就是这样...
And my CfxInitializer like this...
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 ./ gradlew build&& java -jar build / libs / gs-spring-boot-0.1.0.jar
When I try to build and start the jar with the typical command ./gradlew build && java -jar build/libs/gs-spring-boot-0.1.0.jar
我收到多个上下文的异常。
I get an Exception for multiple Contexts.
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并将其添加到Application Class中来修复它。
Similarly to Dave's answer I was able to fix it by removing the ServletContextInitializer and adding a bean to the Application Class.
@Bean
public ServletRegistrationBean servletRegistrationBean(){
return new ServletRegistrationBean(new CXFServlet(),"/api/*");
}
推荐答案
Spring Boot嵌入式servlet功能旨在与 Servlet
和 ServletRegistration
@Beans
一起使用,而不是使用 ContextLoaderListener
(这似乎是试图窃取 ServletContext
属性作为根上下文)。尝试为您的servlet添加 ServletRegistration
;如果它是Spring已知的,并且假设它具有允许您更改应用程序上下文或上下文位置的接口,那么您应该能够在注册中对其进行配置。
The Spring Boot embedded servlet features are designed to work with Servlet
and ServletRegistration
@Beans
, and not with the ContextLoaderListener
(which looks like it is trying to steal the ServletContext
attribute for the root context). Try adding a ServletRegistration
for your servlet instead; if it is Spring aware, assuming it has an interface that lets you change the application context or the context location, then you should be able to configure it in the registration.
