can't serve static files spring

I'm really new to spring and that's why it can be very stupid question, but I got troubled with serving static files. I'm creating a REST api for library app and have some logic when user tries to add a book:
I get principal user from SecurityContextHolder.
I add book and add book to user's list of books
I read the bytes from base64 encoded string and write it to pdf file, stored in /resources/static
And that works. But I don't know how to get this file. I tried to do next:
I made ResourceConfig class that extends WebMvcConfigurer, but it's not worked:
#Configuration
public class ResourceConfig implements WebMvcConfigurer {
#Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry
.addResourceHandler("/static/**")
.addResourceLocations(StaticAbsolutePath.getPath());
}
}
Oh, the StaticAbsolutePath.getPath() is the metod I made to get path to static directory:
public class StaticAbsolutePath {
private static final String path = "A:\\java\\projects\\books\\src\\main\\resources\\static";
public StaticAbsolutePath() {
}
public static String getPath() {
return path;
}
}
I decided that my security config is blocking this path cuz I'm not authorized, so I added this to config class:
http.authorizeRequests().antMatchers("/static/**").permitAll();
But it'a also was useless. When I try to serf to http://localhost:8080/static/1252356147.pdf, it says that "Whitelabel Error Page".
And here is the screen of resources directory:
So if you know what can be the problem, please tell me, I'd really apreciate it!
Here is the full code of SecurityConfig:
#Configuration #EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
#Autowired
private UserDetailsService userDetailsService;
private final BCryptPasswordEncoder bCryptPasswordEncoder = new BCryptPasswordEncoder();
#Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(userDetailsService).passwordEncoder(bCryptPasswordEncoder);
}
#Override
protected void configure(HttpSecurity http) throws Exception {
CustomAuthenticationFilter customAuthenticationFilter = new CustomAuthenticationFilter(authenticationManagerBean());
customAuthenticationFilter.setFilterProcessesUrl("/api/login");
http.csrf().disable();
http.authorizeRequests().antMatchers("/api/login/**").permitAll();
http.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);
http.authorizeRequests().antMatchers(HttpMethod.POST, "/api/users/").authenticated();
http.authorizeRequests().antMatchers(HttpMethod.GET, "/api/user/current").authenticated();
http.authorizeRequests().antMatchers(HttpMethod.POST, "/api/books/**").authenticated();
http.authorizeRequests().antMatchers(HttpMethod.GET, "/api/books/**").permitAll();
http.authorizeRequests().antMatchers(HttpMethod.PUT, "/api/books/**").authenticated();
http.authorizeRequests().antMatchers("/static/**").permitAll();
http.addFilter(customAuthenticationFilter);
http.addFilterBefore(new CustomAuthorizationFilter(), UsernamePasswordAuthenticationFilter.class);
}
#Bean
#Override
public AuthenticationManager authenticationManagerBean() throws Exception {
return super.authenticationManagerBean();
}
}
UPDATE
I understood that in resources/staic directory should be stored files like HTML and CSS thanks to #Akhil. And I also added the lines of code that he suggested. So my ResourceConfig class now looks like this:
private static final String[] CLASS_PATH_RESOURCE_LOCATIONS = {
"A:\\downloads\\"
};
#Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry
.addResourceHandler("/pdf/**")
.addResourceLocations(CLASS_PATH_RESOURCE_LOCATIONS)
.setCacheControl(CacheControl.noCache().cachePrivate())
.resourceChain(true)
.addResolver(new PathResourceResolver());
}
And I changed the directory to store user uploaded files:
But it still not working :(
Full project structure:

Firstly, static files mean files that rarely change for example HTML, CSS files, etc. In your case, the user can upload a pdf file anytime that indicates it's not a static file. What I would suggest is to use a different directory to store PDF and give that path in your resourceConfig. However, if you want to store it in your /resources/static directory then you can do something like this.
ResourceConfigs:
#Configuration
#EnableWebMvc
public class ResourceConfigs implements WebMvcConfigurer {
private static final String[] CLASS_PATH_RESOURCE_LOCATIONS = {
"A:\\downloads\\pdfFiles\\"
};
#Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/pdf/**")
.addResourceLocations(CLASS_PATH_RESOURCE_LOCATIONS)
.setCacheControl(CacheControl.noCache().cachePrivate())
.resourceChain(true)
.addResolver(new PathResourceResolver());
}
}
With this configuration, you can have links like this,
http://localhost:8080/pdf/**
You don't need to configure spring security for this

spring mvc no xml configuration 404 error

I am trying to develop a simple Spring MVC with no XML application .its basically show a simple home page. I am using tomcat on JetBrains IDE for development and problem is that when I run it on tomcat I see 404 error this is url http://localhost:8080/MySpringSecurityApp_war/
this is a controller
#Component
public class DemoController {
#GetMapping("/")
public String showHome(){
return "home";
}
}
#Configuration
#EnableWebMvc
#ComponentScan(basePackages = "com.luv2code.springsecurity.demo")
public class DemoAppConfig {
//define a bean for view resolver
#Bean
public ViewResolver viewResolver(){
InternalResourceViewResolver viewResolver=new InternalResourceViewResolver();
viewResolver.setPrefix("/WEB-INF/view/");
viewResolver.setSuffix(".jsp");
return viewResolver;
}
}
public class MySpringMvcDispatcherServletInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
#Override
protected Class<?>[] getRootConfigClasses() {
return new Class[0];
}
#Override
protected Class<?>[] getServletConfigClasses() {
return new Class[] {DemoAppConfig.class};
}
#Override
protected String[] getServletMappings() {
return new String[]{"/"};
}
}
this is error log
9-Jun-2020 13:32:07.511 WARNING [http-nio-8080-exec-1] org.springframework.web.servlet.PageNotFound.noHandlerFound No mapping found for HTTP request with URI [/MySpringSecurityApp_war/] in DispatcherServlet with name 'dispatcher'
09-Jun-2020 13:32:07.604 WARNING [http-nio-8080-exec-4] org.springframework.web.servlet.PageNotFound.noHandlerFound No mapping found for HTTP request with URI [/MySpringSecurityApp_war/] in DispatcherServlet with name 'dispatcher'
this is also how my project structure

You need to define a resource path if you adding something into your URL (after host part basically in your case MySpringSecurityApp_war) you are calling localhost:8080/MySpringSecurityApp_war/ but you didn't define the resource path anywhere so I guess what you need to do is either add #RequestMapping("/MySpringSecurityApp_war/") at class level or just call localhost:8080/ without any resource path
You can also use #RestController in place of #Component.
I hope it will work.

Unable to resolve static resources in Spring MVC

I know this question has a lot of answers but i cannot solve mine so that is why i decided to put up the question
I want to resolve both jsp and html files. Below is my spring resolver configuration
#Bean
public ViewResolver getViewResolver() {
InternalResourceViewResolver resolver = new InternalResourceViewResolver();
resolver.setPrefix("/WEB-INF/views/");
resolver.setSuffix("");
return resolver;
}
#Override
public void addResourceHandlers(final ResourceHandlerRegistry registry) {
registry.addResourceHandler("/static/**").addResourceLocations("/WEB-INF/views/static");
}
and controller class is below:
#RequestMapping("/testApi2")
#Controller
public class TestController2
{
#RequestMapping("/showHomePage")
public ModelAndView showHome(){
return new ModelAndView("/static/about.html");
}
}
I have also attached screen shot of my directory structure, it is giving 404 on every request

I think that you should add to your web resolver config class one very special handling configurer:
#Override
public void configureDefaultServletHandling(
DefaultServletHandlerConfigurer configurer) {
configurer.enable();
}
This method enables static resources processing.

After some efforts , thanks to lot of documentation on Spring , i was able to resolve the issue
I found a solution(searched on net) with which we can use both JSP and HTML as views
Forget the question , below are the new settings
Static resources (.css,.js,.jpg) are placed in webapp/assets/
HTML files are in /WEB-INF/static/
Here is my configuration file :
#Bean
public ViewResolver getViewResolver() {
InternalResourceViewResolver resolver = new InternalResourceViewResolver();
resolver.setPrefix("/WEB-INF/views/");
resolver.setSuffix("");
return resolver;
}
#Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/assets/**") //
.addResourceLocations("/assets/").setCachePeriod(31556926);
}
#Override
public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
configurer.enable();
}
Please note i have used resolver.setSuffix("") both HTML and JSP
HTML code :
<link rel="stylesheet" href="/taxi/assets/css/theme-pink.css" />
Here taxi is the context root , means name of the project
Now if i run the below URL , it will fetch the image or CSS of js
localhost:8080/taxi/assets/css/icons.css

What should the template path be when using Spring Boot and a Sitemesh filter?

I'm trying to make use of Sitemesh (3) templating with Spring Boot (4+) using Java annotation based config.
When I hit the controller URL, the handler method is invoked.
The Sitemesh filter is activated (debugging proves that).
However I am getting a 404, which I believe is because with the config I have the Freemarker template isn't found (wrong path somewhere).
Code follows, any suggestions what I'm doing wrong would be great!
Filter:
#WebFilter
public class SitemeshFilter extends ConfigurableSiteMeshFilter {
#Override
protected void applyCustomConfiguration(SiteMeshFilterBuilder builder) {
System.out.println("in sitemesh filter");
builder.addDecoratorPath("/*", "templates/main.ftl")
.setMimeTypes("text/html")
.addExcludedPath("/javadoc/*")
.addExcludedPath("/brochures/*");
}
Controller:
#Controller
public class UserController {
#Autowired
MemberService memberService;
#RequestMapping(value="member/{id}")
public ModelAndView viewMember(#PathVariable("id") int memberId, ModelAndView mv) {
mv.setViewName("member");
ClubMember member = memberService.getClubMember(memberId);
mv.addObject("member", member);
return mv;
}
}
Main class:
#SpringBootApplication
#ServletComponentScan
#EnableAutoConfiguration(exclude = {ErrorMvcAutoConfiguration.class})
public class ClubManagementApplication {
public static void main(String[] args) {
SpringApplication.run(ClubManagementApplication.class, args);
}
}
Application.properties:
spring.mvc.view.prefix=/views/
My templates live in :
src/main/resources/templates <- this is where I've put the sitemesh templates live
src/main/resources/views <- here are the Freemarker pages

In case anyone else has same issue:
templates ended up in resources/templates
sitemeshfilter:
#Override
protected void applyCustomConfiguration(SiteMeshFilterBuilder builder) {
builder.addDecoratorPath("/*", "/main.ftl")
.setMimeTypes("text/html", "application/xhtml+xml", "application/vnd.wap.xhtml+xml");
}
Note nothing before '/main.ftl'

Spring MVC - Return static page

I'm struggling with trying to return a static web page from a spring MVC controller.
I followed this tutorial: http://www.tutorialspoint.com/spring/spring_static_pages_example.htm and yet it still isn't working.
This is how I defined the configuration (used configuration class):
#Configuration
#EnableWebMvc
#EnableTransactionManagement
#ComponentScan({ "com.my.web.api"})
#ImportResource("classpath:db-context.xml")
public class ApiServletConfig extends WebMvcConfigurerAdapter {
#Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
}
#Bean
public InternalResourceViewResolver internalResourceViewResolver() {
InternalResourceViewResolver internalResourceViewResolver = new InternalResourceViewResolver();
internalResourceViewResolver.setPrefix("/resources/");
internalResourceViewResolver.setSuffix("*.html");
return internalResourceViewResolver;
}
}
The controller method:
#RequestMapping(value = "/{id}/view", method = RequestMethod.GET, produces = "text/html")
#ResponseBody
public String getPostByIdHtml( #PathVariable String id) throws IOException {
return "/resources/Post.html";
}
Under the webapp folder there's a folder named "resources" and under which there's a file "Post.html". What else should I do in order to get this page returned as HTML instead of getting the string "resources/Post.html"?
Thanks for the help.

Please remove the annotation #ResponseBody. Your browser should be redirected to the desired page once the annotation is removed.
This annotation indicates that the value returned by a method in your controller should be bound to the web response body. In your case, you do not need that: you need Spring to render page /resources/Post.html, so no need for this annotation.
