I am trying to get up with the built-in Tomcat using spring-boot. I want to use CXF for a set of web services in an application, but I cannot figure out how to get out of the CXF servlet.
My main class is as follows:
@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;
}
}
And my CfxInitializer is 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/*");
}
}
When I try to build and run a jar using a typical command ./gradlew build && java -jar build/libs/gs-spring-boot-0.1.0.jar
I get an exception for several 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!

Similar to Dave's answer, I was able to fix it by removing ServletContextInitializer and adding a bean to the application class.
@Bean
public ServletRegistrationBean servletRegistrationBean(){
return new ServletRegistrationBean(new CXFServlet(),"/api/*");
}
