JSP/SpringMVC not finding the resources folder

I'm developing a webapp using Spring MVC/JSP with Java 11, and SpringMVC 5.2.0, which started with config files, but I wanted to give programatic config (through java) a try. I've got the Servlet running, and I've successfully made the login page to "intercept" any other .jsp view if the user is not logged... However, I haven't been able to get my resources from my resource folder.
Every resource that should be loaded from there (e.g.
<link type="image/png" rel="icon" href="${contextPath}/resources/img/icon.png">) I get a 404 response, and in my IDE (Netbeans 11) I get the following message in the Network Monitor:
Request URL: http://localhost:8080/icon.png
Method: GET
Status: 404
Note: The URL should be http://localhost:8080/dragonline/resources/img/icon.png (<c:set var="contextPath" value="${pageContext.request.contextPath}"/>)
Here's my config java file:
package com.midknightmunch.dragonline.config;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.support.ReloadableResourceBundleMessageSource;
import org.springframework.web.servlet.ViewResolver;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.ViewControllerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
import org.springframework.web.servlet.view.InternalResourceViewResolver;
import org.springframework.web.servlet.view.ResourceBundleViewResolver;
import org.springframework.web.servlet.view.JstlView;
#EnableWebMvc
#Configuration
#ComponentScan(basePackages = {"com.midknightmunch.dragonline"})
public class WebConfig implements WebMvcConfigurer{
#Override
public void addViewControllers(ViewControllerRegistry registry) {
registry.addViewController("/").setViewName("index");
}
#Override
public void addResourceHandlers(final ResourceHandlerRegistry registry) {
registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
//registry.addResourceHandler("/img/**").addResourceLocations("/resources/img/");
//registry.addResourceHandler("/css/**").addResourceLocations("/resources/css/");
//registry.addResourceHandler("/js/**").addResourceLocations("/resources/js/");
//I've tried with and without these 3 (the commented ones)
}
#Bean
public ViewResolver internalViewResolver() {
InternalResourceViewResolver bean = new InternalResourceViewResolver();
bean.setViewClass(JstlView.class);
bean.setPrefix("/WEB-INF/views/");
bean.setSuffix(".jsp");
bean.setOrder(0);
return bean;
}
#Bean
public ViewResolver resourceBundleViewResolver() {
ResourceBundleViewResolver bean = new ResourceBundleViewResolver();
bean.setBasename("views");
bean.setOrder(1);
return bean;
}
#Bean("messageSource")
public ReloadableResourceBundleMessageSource messageSource() {
ReloadableResourceBundleMessageSource bean = new ReloadableResourceBundleMessageSource();
String[] basenames = {"classpath:validation"};
bean.setBasenames(basenames);
return bean;
}
}
And my project structure:
icon.png: dragonline/src/main/webapp/resources/img/icon.png
views(including the jsp trying to import this image): dragonline/src/main/webapp/WEB-INF/views/login.jsp
I've tried moving the resources folder everywhere, but everytime I get a 404.
Please, any help would be appreciated.

I figured it out. The problem was that I did not grant permission in my Spring Security config file to access the resources folder, so I solved it by adding:
http.authorizeRequests().antMatchers("/resources/**").permitAll()
in my WebSecurityAdapter's config() method

Spring Boot application endpoint returns 403

I'm new to Spring Boot and currently stuck. I followed this (https://github.com/AppDirect/service-integration-sdk/wiki) Tutorial, as I want to implement an application that integrates itself into AppDirect. In the log I can see that the endpoints get created and mapped:
2018-10-29 16:32:48.898 INFO 8644 --- [ main] s.w.s.m.m.a.RequestMappingHandlerMapping : Mapped "{[/api/v1/integration/processEvent],methods=[GET],produces=[application/json]}" onto public org.springframework.http.ResponseEntity<com.appdirect.sdk.appmarket.events.APIResult> com.appdirect.sdk.appmarket.events.AppmarketEventController.processEvent(javax.servlet.http.HttpServletRequest,java.lang.String)
But when I try to access the endpoint (http://localhost:8080/api/v1/integration/processEvent) with Browser or Http-Requester I get the following response:
{timestamp":"2018-10-29T08:50:13.252+0000","status":403,"error":"Forbidden","message":"Access Denied","path":"/api/v1/integration/processEvent"}
My application.yml looks like this:
connector.allowed.credentials: very-secure:password
server:
use-forward-headers: true
tomcat:
remote_ip_header: x-forwarded-for
endpoints:
enabled: true

This is my Application.java:
package de.....;
import java.nio.charset.Charset;
import java.util.Collections;
import java.util.List;
import org.springframework.boot.SpringApplication;
import org.springframework.http.MediaType;
import org.springframework.http.converter.FormHttpMessageConverter;
import org.springframework.http.converter.HttpMessageConverter;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
public class Application extends WebMvcConfigurerAdapter {
public static void main(String... args) {
SpringApplication.run(RootConfiguration.class, args);
}
/**
* Hack to make Spring Boot #Controller annotated classed to recognize the 'x-www-form-urlencoded' media type

*/
#Override
public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
FormHttpMessageConverter converter = new FormHttpMessageConverter();
MediaType mediaType = new MediaType("application", "x-www-form-urlencoded", Charset.forName("UTF-8"));
converter.setSupportedMediaTypes(Collections.singletonList(mediaType));
converters.add(converter);
super.configureMessageConverters(converters);
}
}
And this is the RootConfiguration.java:
package de.....;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Import;
import com.appdirect.sdk.ConnectorSdkConfiguration;
import com.appdirect.sdk.appmarket.DeveloperSpecificAppmarketCredentialsSupplier;
import com.appdirect.sdk.credentials.StringBackedCredentialsSupplier;
import de.....;
#Configuration
#Import({
ConnectorSdkConfiguration.class,
EventHandlersConfiguration.class
})
#EnableAutoConfiguration
public class RootConfiguration {
#Bean
public DeveloperSpecificAppmarketCredentialsSupplier environmentCredentialsSupplier(#Value("${connector.allowed.credentials}") String allowedCredentials) {
return new StringBackedCredentialsSupplier(allowedCredentials);
}
}
Any help is appreciated as intensive googleing didn't help.
Thanks in advance.

Adding the following class and registering it in Application.java solved my problem:
package de.......;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.annotation.Order;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
#Configuration
#EnableWebSecurity
#Order(1)
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {
#Override
protected void configure(HttpSecurity httpSecurity) throws Exception {
httpSecurity.authorizeRequests().antMatchers("/").permitAll();
}
}

Spring MVC with hibernate in an ear application using only annotation is not working

I have created ear project with one web module and one EJB module.
I'm using web module for Spring MVC view and controller. Model, service and repository are maintained in ejb module. (tried in JAR module as well).
I'm getting exception like, [springframework.web.servlet.DispatcherServlet] (ServerService Thread Pool -- 168) Context initialization failed: java.lang.IllegalStateException: Cannot load configuration class: com.sakthi.core.config.HibernateConfiguration Exception.

My Complete project is copied in github URL: https://github.com/newway86/Spring4MVCHibernateEAR/tree/master/myapp
Please help me... I'm trying for 2 months. Not yet getting the sollution.
This actual program has been taken from this URL: http://websystique.com/springmvc/spring-4-mvc-and-hibernate4-integration-example-using-annotations/
If I try the above example in web project, its working fine. But not working while I create it as a ear project and moved the core logics to the ejb module.

spring web-mvc 4 java config doesn't work

I'm trying to run elementary spring-4 web-mvc application without xml configuration at all. I've looked spring documentation and examples, but it didn't work for me.
My controller:
package com.nikolay.exam.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;
#Controller
public class HomeController {
#RequestMapping(value = "/home", method = RequestMethod.GET)
#ResponseBody
public String home() {
return "Hello world!";
}
}
AppConfig:
package com.nikolay.exam.config;
import org.springframework.context.annotation.Configuration;
#Configuration
public class AppConfig {
}
WebConfig:
package com.nikolay.exam.config;
import com.nikolay.exam.controller.HomeController;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
#Configuration
#EnableWebMvc
public class WebConfig extends WebMvcConfigurerAdapter {
#Bean
public HomeController homeController() {
return new HomeController();
}
}
And WebInitializer:
package com.nikolay.exam.config;
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 javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.ServletRegistration;
public class WebInitializer implements WebApplicationInitializer {
#Override
public void onStartup(ServletContext servletContext) throws ServletException {
AnnotationConfigWebApplicationContext root = new AnnotationConfigWebApplicationContext();
root.setConfigLocation("com.nikolay.exam.config");
servletContext.addListener(new ContextLoaderListener(root));
ServletRegistration.Dynamic dispatcher = servletContext.addServlet("dispatcher", new DispatcherServlet(root));
dispatcher.setLoadOnStartup(1);
dispatcher.addMapping("/*");
}
}
But when I run my application on tomcat I receive an error:
14-Feb-2015 11:35:29.825 WARNING [http-nio-8080-exec-1] org.springframework.web.servlet.PageNotFound.noHandlerFound No mapping found for HTTP request with URI [/home/] in DispatcherServlet with name 'dispatcher'

I think it's the way you register your config class that is not correct.
Try using the AnnotationConfigWebApplicationContext#register instead.
AnnotationConfigWebApplicationContext appContext = new AnnotationConfigWebApplicationContext();
appContext.register(WebConfig.class);

Probably you need to change
dispatcher.addMapping("/*");
to
dispatcher.addMapping("/");
