Configure Static Resources in Spring MVC
1. The objective of the document

The document is based on:
Eclipse 4.6 (NEON)
Spring 4 MVC
In this post, I will guide you to configure static data sources in Spring MVC which are normally images, css files, and javascript,...
Spring MVC allows you to map between an URL and a specific location of the data source. You can see the illustration below:
2. Create Maven Project
No ADS
- File/New/Other..
Enter:
- Group ID: org.o7planning
- Artifact ID: SpringMVCStaticResource
- Package: org.o7planning.tutorial.springmvcresource
Project is created.
Do not worry with the error message when Project has been created. The reason is that you have not declared Servlet library.
Note:
Eclipse 4.6 (NEON) create Maven project structure may be wrong. You need to fix.

SpringWebAppInitializer.java
package org.o7planning.springmvcresource.config;
import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.ServletRegistration;
import org.springframework.web.WebApplicationInitializer;
import org.springframework.web.context.support.AnnotationConfigWebApplicationContext;
import org.springframework.web.servlet.DispatcherServlet;
public class SpringWebAppInitializer implements WebApplicationInitializer {
@Override
public void onStartup(ServletContext servletContext) throws ServletException {
AnnotationConfigWebApplicationContext appContext = new AnnotationConfigWebApplicationContext();
appContext.register(ApplicationContextConfig.class);
ServletRegistration.Dynamic dispatcher = servletContext.addServlet("SpringDispatcher",
new DispatcherServlet(appContext));
dispatcher.setLoadOnStartup(1);
dispatcher.addMapping("/");
}
}
ApplicationContextConfig.java
package org.o7planning.springmvcresource.config;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.view.InternalResourceViewResolver;

public InternalResourceViewResolver getViewResolver() {
InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
viewResolver.setPrefix("/WEB-INF/pages/");
viewResolver.setSuffix(".jsp");
return viewResolver;

WebMvcConfig.java

Note:
Configuring Static Resource:
// Css resource.
registry.addResourceHandler("/styles/**") //
.addResourceLocations("/WEB-INF/resources/css/");
