              Serve Custom static resource locations in Spring Boot.md
            
          
    Configure Spring Boot Application to serve Custom Static Resource locations

Static resources can be configured using two approaches in Spring Boot

Add custom path in application.properties/application.yaml
Implement WebMvcConfigurer addResourceHandlers() method

First configure your SpringSecurity class to accept requests to this resources
@Override
public void configure(WebSecurity web)
{
    web.ignoring()
            .antMatchers( "/static/**","/resources/**", "/js/**", "/css/**", "/images/**");

}

Then use any one of the following way to serve static content
Approach-1


Open application.properties/application.yaml file and add the following line based on your directory structure

spring.resources.static-locations=classpath:/static/,classpath:/static/vendor/,classpath:/static/custom/


By default classpath points to /resources/ directory under project root. So, static folder/file locations should be relative from that directory.


Example:


Absoulte Path: /Users/johnd/IdeaProjects/SpringSessionTest/src/main/resources/static/vendor/css/bootstrap.min.css
Project Structure: SpringSessionTest/src/main/resources/static/vendor/css/bootstrap.min.css

In this case, your static-locations should be spring.resources.static-locations=classpath:/static/,classpath:/static/vendor/ and in your web page you can use

<link href="css/bootstrap.min.css" rel="stylesheet"> to link this stylesheet
Approach-2


Create class ApplicationConfig that extends WebMvcConfigurer interface and configure your locations in CLASSPATH_RESOURCE_LOCATIONS string array

@Configuration
public class ApplicationConfig implements WebMvcConfigurer
{
    private static final String[] CLASSPATH_RESOURCE_LOCATIONS =
    {
        "classpath:/META-INF/resources/", "classpath:/resources/",
        "classpath:/static/", "classpath:/public/","classpath:/static/vendor/","classpath:/static/custom/"
    };

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry)
    {
        registry.addResourceHandler("/**").addResourceLocations(CLASSPATH_RESOURCE_LOCATIONS);
    }
}
