I am using Spring Boot 2.0.0 M1 with WebFlux to build my sample web application. After succeeding with REST endpoints I've decided to add some views to my application. I've decided to use Thymeleaf 3.x version. I know that Spring serves static content from 4 default location:
/META-INF/resources/
/resources/
/static/
/public/
I've decided to go with second example so my css file is in /resources/static/css/. However after loading my page .css file was not found.
This is a screenshot from my IDE:
I am not providing my own configuration for static directory I just want to use default one. What might be important is the fact that templates are loading just fine from the /resources/templates/ directory.
Css file is loaded like this:
<link data-th-href="#{css/bootstrap.min.css}" rel="stylesheet">
App is not using normal Controller class instead I've provided function as a Bean to define my router:
#Bean
RouterFunction<?> router(final GeneratorHandler generatorHandler) {
return route(GET("/generate"), handler::render);
}
Any ideas what's wrong here?
I've found the right solution. In your RouterFunction you need to use:
return resources("/**", new ClassPathResource("/static/"))
This will set your static directory to:
:classpath/static

This is a bit of a silly and frustrating one:
The #Configuration is taken from a tutorial website or forum and in it a
ServletContextTemplateResolver thymeleafTemplateResolver
is created using the ServletContext provided by spring boot.
When requested, a FileNotFoundException is thrown, despite the file being in the configured resources folder.
How do I get it to find the file / load it from the resources?
For thymeleaf to resolve the classpath resources, you need to configure a ClassLoaderTemplateResolver. (You were using a ServletContextTemplateResolver)
Also check that setPrefix is set to the correct folder, eg. "/thymeleaf/" if your documents are in resources/thymeleaf/ and that setSuffix is set to ".html" (or whatever your preferred file suffix is)
To also serve static content, you can extend WebMvcConfigurer and override addResourceHandlers, to then do e.g.
registry.addResourceHandler("/**").addResourceLocations("classpath:/static/");
assuming a static folder in your resources.
(Spring controllers take precedence here)
Updated: to describe the question more clearly
I create a web applicaiton with spring boot and thymeleaf, everything works fine if I open the login page, then login, then head for the management module or reports module sequently.
The proleam occurs when I type the url locahost:8080/send/kf/index(needs to authenticate, but I have open access to all in customized filter) in the browser, the page loads without js and css. In debug mode, I saw /send/kf was unexpectly put into the path like the following. I can get the resource if I access localhost:8080/assets/avatars/avatar.png.
The following is the folder structure I put my static resources. How could /send/kf automatically added into the url, please help me solve this problem. Thanks!
you can use spring.resources.static-locations in your application.properties file
spring.resources.static-locations=classpath:/resources/css/
spring.mvc.static-path-pattern=/resources/**
this is taken form documentation
Note:Static resources, like JavaScript or CSS, can easily be served from your Spring Boot application just be dropping them into the right place in the source code. By default Spring Boot serves static content from resources in the classpath at "/static" (or "/public")
Using /assets/ instead of assets/ fixes the issue, as otherwise it's a relative url that's supposed to get added to the end of existing url.
I find a solution for this question. I don't know how /send/kf is put into the url for the static resources, but I think if I put the controller mapping under the root path, this problem should avoid. As I think, the url is correct and resources can load successfully.
#Controller
public class ManualMessageController {
#Autowired
private MsgTemplateRepository msgTemplateRepository;
#RequestMapping("/manualMsg")
public String manualMsg(Model model){
model.addAttribute("msgTemplateList", msgTemplateRepository.findByStatus(1));
return "manualMessage";
}
}
updated:
The right solution is to use absolute path rather than relative path in the project. So change assets/css to /assets/css works.
(I examined similar questions, but none of them explain the odd behavior I illustrate at the end of this question.)
I have a Spring Boot 1.3.5 application that insists on replacing my favicon with Boot's default favicon (the green leaf). To resolve the problem, I have tried the following:
Install my own favicon at my application's static root.
The word on the street is that this is just supposed to work. Unfortunately, it does not.
Set property spring.mvc.favicon.enabled to false.
This is supposed to disable org.springframework.boot.autoconfigure.web.WebMvcAutoConfiguration.WebMvcAutoConfigurationAdapter.FaviconConfiguration, which appears to responsible for serving Boot's default favicon. By setting a breakpoint in that class, I was able to confirm that the beans defined in that class indeed do not get created when the property is set to false.
Unfortunately, this didn't solve the problem, either.
Implement my own favicon handler:
#Configuration
public class FaviconConfiguration {
#Bean
public SimpleUrlHandlerMapping faviconHandlerMapping() {
SimpleUrlHandlerMapping mapping = new SimpleUrlHandlerMapping();
mapping.setOrder(Integer.MIN_VALUE);
mapping.setUrlMap(Collections.singletonMap("**/favicon.ico", faviconRequestHandler()));
return mapping;
}
#Bean
protected ResourceHttpRequestHandler faviconRequestHandler() {
ResourceHttpRequestHandler requestHandler = new ResourceHttpRequestHandler();
ClassPathResource classPathResource = new ClassPathResource("static/");
List<Resource> locations = Arrays.asList(classPathResource);
requestHandler.setLocations(locations);
return requestHandler;
}
}
Sadly, no luck here, too.
Rename my favicon from favicon.ico to logo.ico, and just point all my pages' favicon links to that, instead.
Now, with this potential fix, I discovered a surprising result. When I curled my newly named icon.ico resource, I was served Spring's leaf icon. However, when I deleted the resource, I got 404. But then, when I put it back, I got the leaf again! In other words, Spring Boot was happy to answer 404 when my static resource was missing, but when it was there, it would always answer with the leaf instead!
Incidentally, other static resources (PNGs, JPGs, etc.) in the same folder serve up just fine.
It was easy to imagine that there was some evil Spring Boot contributor laughing himself silly over this, as I pulled my hair out. :-)
I'm out of ideas. Anyone?
As a last resort, I may just abandon using an ICO file for my site icon, and use a PNG instead, but that comes at a cost (losing multi-resolution support), so I'd rather avoid that.
This is a spring boot feature:
Spring MVC auto-configuration
Spring Boot provides auto-configuration for Spring MVC that works well with most applications.
The auto-configuration adds the following features on top of Spring’s defaults:
Inclusion of ContentNegotiatingViewResolver and BeanNameViewResolver
beans.
Support for serving static resources, including support for
WebJars (see below).
Automatic registration of Converter,
GenericConverter, Formatter beans.
Support for HttpMessageConverters
(see below).
Automatic registration of MessageCodesResolver (see
below).
Static index.html support.
Custom Favicon support.
Automatic use of a ConfigurableWebBindingInitializer bean (see below).
You can find this document at: http://docs.spring.io/spring-boot/docs/1.4.1.RELEASE/reference/htmlsingle/#boot-features-spring-mvc-auto-configuration
And, If you want to disable spring boot favicon, you can add this config to you yml or perperties files
spring.mvc.favicon.enabled=true # Enable resolution of favicon.ico.
Or, If you want change favicon to you own. try this:
#Configuration
public static class FaviconConfiguration {
#Bean
public SimpleUrlHandlerMapping faviconHandlerMapping() {
SimpleUrlHandlerMapping mapping = new SimpleUrlHandlerMapping();
mapping.setOrder(Integer.MIN_VALUE);
mapping.setUrlMap(Collections.singletonMap("mylocation/favicon.ico",
faviconRequestHandler()));
return mapping;
}
}
And you can find more detail at: Spring Boot: Overriding favicon
UPDATE:
put favicon.ico to resources folder.
And, try it:
Why choose the hard way, when u can get the easy one?
just create a new link into ur <head> with:
<link rel="icon" type="image/png" href="images/fav.png" />
Copy and paste ur icon in src/main/resources/static/images/
Rename the file to whatever you want, just remember to change the link in the html too.
After using JHipster on a couple of new projects recently (Highly recommended ! Amazing work !), I am trying to back-port some of the concepts into an older webapp, essentially migrating it to Spring Boot and Angular.
In Spring Boot, the default location for static web resources (HTML, JS, CSS, etc.) is in a directory called public, static or resources located at the root of the classpath. Any of these directories will be picked up by spring boot and files in them will be accessible via HTTP.
In JHipster the web files are in the src/main/webapp directory. Which is the directory used by default in a classic Maven WAR project.
I like this better because :
it more clearly separates the static web stuff from the classpath resources used by the Java code
the nesting is less deep (we already have enough levels of directories nesting with Maven as it is!).
But if I just create webapp directory in my project and put my HTML files in it, they are not available via HTTP, and the build process creates the WEB-INF directory structure in it. I don't want that, and in JHipster this is not the case.
How can I configure Spring Boot to behave like it does in JHipster ?
For those not familiar with JHipster : How can I instruct Spring Boot to serve static files from a different folder, no included in the classpath ?
You can try following configuration. The idea should be pretty straight forward. It does register artifacts in assets directory.
public class AppMvcConfiguration extends WebMvcConfigurerAdapter {
#Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
// Including all static resources.
registry.addResourceHandler("/assets/**",
"/css/**",
"/img/**",
"/js/**"
).addResourceLocations("/assets/",
"/css/",
"/img/",
"/js/"
).resourceChain(true)
.addResolver(new PathResourceResolver());
super.addResourceHandlers(registry);
}
}
you can add following code in application.propertise:
spring.resources.static-locations=classpath:/webapp/
and following code in application.yaml:
resources:
static-locations: classpath:/webapp/
I recently had the same issue and simply did a text search for "robots.txt" within my jHipster generated files.
I added my new file to the assets array in angular.json and put my new file in the same location as robots.txt, which as stated earlier is webapps.
I am developing a new poc for web application from Spring Boot. The packaging type of my application in war. In this all i want is to display some contents on a jsp. For that i have created a small jsp, and requierd css/images/js files i have put in resources/static folder. So my static folder contains css/images/js folders. I've added following code in my configuration file. My configuration extends from WebMvcConfigurerAdapter
public void addResourceHandlers(ResourceHandlerRegistry registry) {
String[] pathPatterns = {"/components/**", "/images/**", "/scripts/**", "/styles/**"};
String[] resourceLocations = {"classpath:/static/components/", "classpath:/static/images/", "classpath:/static/scripts/, classpath:/static/styles/"};
registry.addResourceHandler(pathPatterns).addResourceLocations(resourceLocations);
}
However, my jsp does not get the reference of these file.
JSP Code
How to solve above problem..
Second concern, as per the spring boot reference documentation, it serves the static content which are located in static folder. that means i should be able to access files from my static folder directly in below way
http://localhost:8080/styles/main.css
But this is also not working
Third Issue - static contents are served by default servlet ..is this true that Default servlet in enabled by default in Spring Boot application
Please Help
Putting the static resources inside src/main/resources/static folder works for me without any addResourceHandlers configuration. For example, I have a css file at
src/main/resources/static/public/css/styles.css
which I refer from my JSP like this:
<link href="/public/css/styles.css" rel="stylesheet">
You should have put your JSPs inside src/main/webapp/WEB-INF, and set the packaging to war rather than jar, due to the limitations of having JSPs in Spring Boot.
