Spring java configuration problem: bean name 'requestMappingHandlerMapping' rejected: URL paths not defined

Question

I am using spring java configs to build a web application.

When I start tomcat, it says that the resource / myapp / myapp was not found

At the console output, I noticed the following. I am not sure if this is causing any problem.

I only show log lines that look weird. because the magazine is so big

INFO: validateJarFile(C:\libraries\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\myapp\WEB-INF\lib\javax.servlet-api-3.0.1.jar) - jar not loaded. See Servlet Spec 2.3, section 9.7.2.

Here is WebAppContextConfig.java

 package com.example; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.ComponentScan; import org.springframework.context.annotation.Configuration; import org.springframework.web.servlet.config.annotation.EnableWebMvc; import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry; import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter; import org.springframework.web.servlet.view.InternalResourceViewResolver; @Configuration @EnableWebMvc @ComponentScan(basePackages = "com.example") public class WebAppContextConfig extends WebMvcConfigurerAdapter{ //Resolve logical view names to .jsp resources in /WEB-INF/views directory @Bean public InternalResourceViewResolver configureInternalResourceViewResolver() { InternalResourceViewResolver resolver = new InternalResourceViewResolver(); resolver.setPrefix("WEB-INF/jsp/"); resolver.setSuffix(".jsp"); return resolver; } @Override public void addResourceHandlers(ResourceHandlerRegistry registry) { registry.addResourceHandler("/scripts/**").addResourceLocations("/scripts/"); registry.addResourceHandler("/css/**").addResourceLocations("/css/"); registry.addResourceHandler("/images/**").addResourceLocations("/images/"); } } 

Here is WebAppInitializer.java

  package com.example; import javax.servlet.ServletContext; import javax.servlet.ServletException; import javax.servlet.ServletRegistration; import org.springframework.context.annotation.ComponentScan; import org.springframework.web.WebApplicationInitializer; import org.springframework.web.context.ContextLoaderListener; import org.springframework.web.context.support.AnnotationConfigWebApplicationContext; import org.springframework.web.servlet.DispatcherServlet; import org.springframework.web.servlet.config.annotation.DefaultServletHandlerConfigurer; public class WebAppInitializer implements WebApplicationInitializer { /* (non-Javadoc) * @see org.springframework.web.WebApplicationInitializer#onStartup(javax.servlet.ServletContext) */ @Override public void onStartup(ServletContext servletContext) throws ServletException { AnnotationConfigWebApplicationContext rootContext = new AnnotationConfigWebApplicationContext(); rootContext.register(WebAppContextConfig.class); servletContext.addListener(new ContextLoaderListener(rootContext)); AnnotationConfigWebApplicationContext dispatcherContext = new AnnotationConfigWebApplicationContext(); dispatcherContext.register(WebAppContextConfig.class); ServletRegistration.Dynamic dispatcher = servletContext.addServlet("dispatcher", new DispatcherServlet(rootContext)); dispatcher.setLoadOnStartup(1); dispatcher.addMapping("/"); DefaultServletHandlerConfigurer defaultConfig = new DefaultServletHandlerConfigurer(servletContext); defaultConfig.enable(); } } 

Also, is there a good place to look for spring mvc java configuration?

thanks

Answer 1

This is not the main reason for @ravi, but I see a few issues that I would like to highlight in order to start with:

a. It seems that you download the Java Spring configuration file twice, through the ContextLoaderListener and the Dispatcher servlet, do it only through the ContextLoaderListener, you can define your DispatcherServlet this way - just load the empty context (ideally, two java configs - one for the main application and one for the web -configuration):

 ServletRegistration.Dynamic dispatcher = servletContext.addServlet("dispatcher", new GenericWebApplicationContext()); dispatcher.setLoadOnStartup(1); dispatcher.addMapping("/"); 

b. Can you enable debug mode with log4j and see what else is logged in - if this is not enough information, log in at the trace level.

from. Interior view The resolver path looks a bit wrong - you are missing the "/" ahead:

 resolver.setPrefix("/WEB-INF/jsp/"); 

Can you try them and see what you see now.
