Issue
I am running a spring boot application with the following application class:
@EnableAutoConfiguration
@Configuration
public class FakeAppBooter extends SpringBootServletInitializer{
public static void main(String args[]) {
SpringApplication.run(FakeAppBooter.class, args);
System.out.println("Test");
}
@Bean
public EmbeddedServletContainerFactory servletContainer() {
TomcatEmbeddedServletContainerFactory factory = new TomcatEmbeddedServletContainerFactory();
factory.setTomcatContextCustomizers(Arrays.asList(new CustomCustomizer()));
factory.addErrorPages(
new ErrorPage(HttpStatus.UNAUTHORIZED,"/WEB-INF/views/unprot/common/errors/containerError.jsp"),
new ErrorPage(HttpStatus.NOT_FOUND,"/WEB-INF/views/unprot/common/errors/containerError.jsp"),
new ErrorPage(HttpStatus.INTERNAL_SERVER_ERROR,"/WEB-INF/views/unprot/common/errors/containerError.jsp"));
MimeMappings mappings = new MimeMappings(MimeMappings.DEFAULT);
mappings.add("xsd", "text/xml");
mappings.add("wsdl", "text/xml");
factory.setMimeMappings(mappings);
return factory;
}
static class CustomCustomizer implements TomcatContextCustomizer {
@Override
public void customize(Context context) {
context.setUseHttpOnly(true);
context.addWelcomeFile("home.html");
}
}
@Bean
public ServletContextInitializer initializer() {
return new ServletContextInitializer() {
@Override
public void onStartup(ServletContext servletContext) throws ServletException {
servletContext.setInitParameter("parentContextKey", "globalContext");
servletContext.setInitParameter("contextConfigLocation", "classpath*:com/my/**/fakeContext.xml");
}
};
}
@Bean
public ServletRegistrationBean mainServlet(){
ServletRegistrationBean servlet = new ServletRegistrationBean();
servlet.setName("main");
servlet.setServlet(new DispatcherServlet());
servlet.addUrlMappings("*.html","*.htmlf","*.json",
"/my/issue","/my/query","/my/adjust","/my/echo");
return servlet;
}
@Bean
public ServletRegistrationBean cxfServlet(){
ServletRegistrationBean servlet = new ServletRegistrationBean();
servlet.setName("CXFServlet");
servlet.setServlet(new CXFServlet());
servlet.setLoadOnStartup(1);
servlet.addUrlMappings("/services/*");
return servlet;
}
@Bean
public ServletRegistrationBean axisServlet(){
ServletRegistrationBean servlet = new ServletRegistrationBean();
servlet.setName("AxisServlet");
servlet.setServlet(new AxisServlet());
servlet.addInitParameter("axis.servicesPath", "/axis/");
servlet.addUrlMappings("/axis/*","*.jws");
return servlet;
}
@Bean
public FilterRegistrationBean httpMethodFilter(){
FilterRegistrationBean filter = new FilterRegistrationBean();
filter.setName("httpMethod");
filter.setFilter(new HiddenHttpMethodFilter());
filter.addUrlPatterns("*.html","*.htmlf","*.json");
return filter;
}
@Bean
public FilterRegistrationBean sitemeshFilter(){
FilterRegistrationBean filter = new FilterRegistrationBean();
filter.setName("sitemesh");
filter.setFilter(new SiteMeshFilter());
filter.addUrlPatterns("*.html");
return filter;
}
}
My layout is as follows
- src/main/java
- boot/FakeAppBooter.java
- src/main/webapp
- WEB-INF
- main-servlet.xml
- WEB-INF
- src/main/resources
I have tried using above layout, as well as moving the WEB-INF folder to the resources folder
If I package the project as war file with WEB-INF under weabpp, I get the WEB-INF folder in the root of the war file, however on startup I get:

If I move the WEB-INF folder to the resources folder and package as a jar file, I get no error on startup, however I still get the FileNotFoundException when I try to load a webpage, as follows:

Solution
Unless you are running your application as WAR, the src/main/webapp folder won't be included in the output as stated in the documentation:
Do not use the
src/main/webappfolder if your application will be packaged as a jar. Although this folder is a common standard, it will only work with war packaging and it will be silently ignored by most build tools if you generate a jar.
So that may be your problem.
To fix it try to set config location explicitly for the main servlet:
servlet.addInitParameter("contextConfigLocation", "classpath:main-servlet.xml");
and place the main-servlet.xml file in src/main/resources.
Hope this helps.
