那些遇到过的问题

Spring Boot无法从资源文件夹中提供静态图像

ale*_*oid 6 spring spring-boot

在我的Spring Boot应用程序中，我有以下静态文件：

\src\main\resources\static\images\social\facebook\f_logo.jpg
Run Code Online (Sandbox Code Playgroud)

这是我的application.properties

server.port: 8080
server.contextPath: /api
Run Code Online (Sandbox Code Playgroud)

我正在尝试通过以下网址访问此文件：

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

但是服务器返回 404 Not Found.

我在做什么错以及如何解决？

和我一样的问题。（弹簧靴 2）

我在下面解决。

第 1 步：将images文件夹从移动src/main/resources/static/images到src/main/webapp/WEB-INF/images

第 2 步：查找SpringBootMainApplication.java添加代码

@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());
}

第 3 步：运行程序并进入浏览器http://localhost:8080/images/logo.png

如果您设置了 contextRoot http://localhost:8080/project/images/logo.png

完整代码：

@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);
    }
}

为我工作。

额外的

或者你可以在下面设置，如果你想在资源文件夹中使用。

@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {

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

因为在下面部署项目结构之后。

在此处输入图片说明

或者

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

对不起英语。

@Configuration
public class WebConfiguration extends WebMvcConfigurationSupport {

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

希望对您有帮助！

也许您已经添加了@EnableWebMvc查找/api/images/social/facebook/f_logo.jpg 与之对应的处理程序的方法，只需提供类似于我的文章的WebMvcConfigurer或WebMvcConfigurationSupport即可将其删除。

  • 它是一个 Spring Boot 应用程序。通常不需要手动配置资源处理程序 (2认同)

这是一个从资源文件夹中提供的干净解决方案。在 Spring Boot v2.1.4.RELEASE 上测试。 在此输入图像描述

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

您可以将其设置为 Application 的嵌套类（或您的任何扩展 SpringBootServletInitializer 的类）。您可以声明许多文件夹，例如

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

确保 src/main/resources 是源文件夹，并且您指定的文件夹直接位于其下。

然后您可以简单地在 html 或 jsp 文件中显示这样的图像。

在您的应用程序属性文件中设置以下行：
