Spring 3, with Java based configuration and resource access issue

I am using Spring 3, a Java based configuration, with BootStrap.

I downloaded the bootloader and put css and js in the resource directory.

The problem is that I cannot use these .css on the freemarker page. Be that as it may, I imported them. Since I am using java based configuration, I added "addResourceHandler" as follows:

WebAppConfig:

@Configuration @EnableWebMvc @ComponentScan("com.springway") public class WebConfig implements WebApplicationInitializer { @Override public void onStartup(final ServletContext servletContext) throws ServletException { final AnnotationConfigWebApplicationContext root = new AnnotationConfigWebApplicationContext(); root.setServletContext(servletContext); root.scan("com.springway"); root.refresh(); final ServletRegistration.Dynamic servlet = servletContext.addServlet("spring", new DispatcherServlet(root)); servlet.setLoadOnStartup(1); servlet.addMapping("/*"); } public void addResourceHandlers(ResourceHandlerRegistry registry) { registry.addResourceHandler("/resources/**").addResourceLocations("/resources/"); }

The Tomcat log says:

"WARNING: No mapping found for HTTP request with URI

[/springway/resources/css/bootstrap-responsive.css] in a DispatcherServlet named 'spring'

Directory:

 -SpringWay > -src > - main > -webapp > -resources -WEB-INF -welcome.ftl -springway.ftl

welcome.ftl:

 [#ftl /] [#include "springway.ftl" /] <ul class="breadcrumb"> <li> <a href="[@spring.url '/test'/]">Test</a> <span class="divider">/</span> </li> <li> <a href="#">Library</a> <span class="divider">/</span> </li> <li class="active">Data</li> </ul>

springway.ftl:

  [#ftl/] [#import "spring.ftl" as spring /] <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title> </title> <link href="[@spring.url '/resources/css/bootstrap-responsive.css'/]" rel="stylesheet" type="text/css" media="screen"/> <link href="[@spring.url '/resources/css/bootstrap-responsive.min.css'/]" rel="stylesheet" type="text/css" media="screen"/> <link href="[@spring.url '/resources/css/bootstrap.css'/]" rel="stylesheet" type="text/css" media="screen"/> <link href="[@spring.url '/resources/css/bootstrap.min.css'/]" rel="stylesheet" type="text/css" media="screen"/> <script src="[@spring.url '/resources/js/bootstrap.js'/]" type="text/javascript"></script> <script src="[@spring.url '/resources/js/bootstrap.min.js'/]" type="text/javascript"></script> </head> <body ></body> </html>

You have identified an invalid resource.

Instead

 registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");

you should have done

 registry.addResourceHandler("/resources/**").addResourceLocations("/resources/**");

Since your css folder is in the resources folder, you need to add an extra ** after / after it determines the css folder, otherwise it will only be downloaded from resource folders, which will not include any subfolders.

Hope this helps you.

Greetings.

If you use Spring Security, you might consider adding webjars to the list of authorized requests by adding this line of code to the SecurityConfiguration class:

 @Configuration @EnableWebMvcSecurity public class SecurityConfiguration extends WebSecurityConfigurerAdapter { @Override protected void configure(HttpSecurity http) throws Exception { http .authorizeRequests() .antMatchers("/resources/**", "/signup", "/about").permitAll() **.antMatchers("/webjars/**").permitAll()** .anyRequest().authenticated() .and() .formLogin().loginPage("/signin").permitAll() .and() //... .logout().permitAll(); }
