Spring Boot unable to serve static image from resource folder

Question

In my Spring Boot application I have a following static file:

\src\main\resources\static\images\social\facebook\f_logo.jpg

This is my application.properties

server.port: 8080
server.contextPath: /api

I'm trying to access this file by the following url:

http://localhost:8080/api/images/social/facebook/f_logo.jpg

but the server returns 404 Not Found.

What am I doing wrong and how to fix it ?

Answer 1

Instead of http://localhost:8080/api/images/social/facebook/f_logo.jpg,

try this http://localhost:8080/images/social/facebook/f_logo.jpg

It should work as the default path starts from /, not /api

Answer 2

Just keep your images in path which you have given \src\main\resources\static\images\social\facebook\f_logo.jpg and while loading images in JSP, give relative path to resources/static like this src="/images/social/facebook/f_logo.jpg". This will load the image.

Answer 3

@Configuration
public class WebConfiguration extends WebMvcConfigurationSupport {

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

I hope this helps you!

Maybe you have added @EnableWebMvc which looks for handlers corresponding to /api/images/social/facebook/f_logo.jpg. Just remove that & provide WebMvcConfigurer or WebMvcConfigurationSupport similar to what I have posted.

Answer 4

Here's a clean solution to serve from resources folder. Tested on Spring Boot v2.1.4.RELEASE.

    @Configuration
    public class WebConfig implements WebMvcConfigurer {      
        @Override
        public void addResourceHandlers(ResourceHandlerRegistry registry) {
            registry.addResourceHandler("/**")
            .addResourceLocations("classpath:/static/","classpath:/image/")
            .setCachePeriod(0);
        }
    }

You can make this a nested class of Application (or whichever class of yours extends SpringBootServletInitializer). You can declare many folders like

.addResourceLocations("classpath:/static/","classpath:/image/","classpath:/largeimage/","classpath:/pdf/")

Make sure src/main/resources is a source folder, and the folders you specify are directly under it.

Then you can simply display images like this in your html or jsp files.

<img src="ok.png"/>

Answer 5

Same problem with me. (Spring Boot 2)

I resolve below.

Step 1: Move images folder from src/main/resources/static/images to src/main/webapp/WEB-INF/images

Step 2: Look up SpringBootMainApplication.java add code

@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {

    // Register resource handler for images
    registry.addResourceHandler("/images/**").addResourceLocations("/WEB-INF/images/")
            .setCacheControl(CacheControl.maxAge(2, TimeUnit.HOURS).cachePublic());
}

Step 3: Run program and go to browser http://localhost:8080/images/logo.png

If your set contextRoot http://localhost:8080/project/images/logo.png

Full Code:

@SpringBootApplication
public class MainApplication implements WebMvcConfigurer {

    private static Logger logger = LoggerFactory.getLogger(MainApplication.class.getName());

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {

        // Register resource handler for images
        registry.addResourceHandler("/images/**").addResourceLocations("/WEB-INF/images/")
                .setCacheControl(CacheControl.maxAge(2, TimeUnit.HOURS).cachePublic());
    }

    public static void main(String[] args) {
        SpringApplication.run(MainApplication.class, args);
    }
}

Work for me.

---

Additional

Or you can set below, If you want using in resources folder.

@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {

    registry.addResourceHandler("/resources/**").addResourceLocations("classpath:/statics/")
            .setCacheControl(CacheControl.maxAge(2, TimeUnit.HOURS).cachePublic());
}

Because after deploy project structure below.

http://localhost:8080/images/logo.png

or

http://localhost:8080/project/images/logo.png

Sorry for English.

Answer 6

I have faced same issue while running spring boot application using apache tomcate 9.0. rightnow resolved the same. 1. i have added validation.properties file in my app. folder structure looking like below, --src/main/resources --static --application.properties --validations.properties 2. next i have moves images,css and js folder under src/main/webapp folder. 3. next i have done below three steps, --cleaned project --maven install --update project 4. finally ran application ,it was working successfully.

Answer 7

in your application properties file set the following line :

spring.resources.static-locations=file:///c:/{yourWorkSpace}/{projectName}/src/main/resources/static/

this is tested.

Answer 8

After some research and reproduce I can confirm that your provided resource path and your link is correct.

In your pom.xml you have many "not Spring-boot related" dependencies. If you want to go further with this configuration, you need to follow gipple lake's answer because you are not using the autoconfiguration of spring-boot-web.

But if you want to get to out of the box solution I would suggest to replace the Spring core dependencies with the Spring-boot related ones.

For example use:

<dependency> 
     <groupId>org.springframework.boot</groupId> 
     <artifactId>spring-boot-starter-web</artifactId> 
</dependency>

instead of:

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-web</artifactId>
    <version>${spring.version}</version>
</dependency>
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-webmvc</artifactId>
    <version>${spring.version}</version>
</dependency>

Maybe you should also add the boot starter dependency:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter</artifactId>
</dependency>

Answer 9

Can you show us your configuration files?

You got 404 when the url is not mapped, please provide us the controller.
