Spring Boot unabe用于提供资源文件夹
在我的Spring Boot应用程序中，我有一个以下静态文件：
\src\main\resources\static\images\social\facebook\f_logo.jpg
这是我的application.properties
server.port: 8080
server.contextPath: /api
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
但服务器返回404 Not Found.
我做错了什么以及如何解决？
已更新

@Configuration
public class WebConfiguration extends WebMvcConfigurationSupport {
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry）{
registry.addResourceHandler("/**")
.addResourceLocations("classpath:/static/");
}
}
我希望它会对你有所帮助！
也许您已添加@EnableWebMvc，它会查找与/api/images/social/facebook/f_logo.jpg对应的处理程序
只需通过提供类似于我的帖子的WebMvcConfigurer或WebMvcConfigurationSupport来删除它。
答案 1 :(得分：3)
我有同样的问题。 （春季启动2）
我在下面解决。
步骤1 ：将images文件夹从src/main/resources/static/images移至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());
}
步骤3 ：运行程序并转到浏览器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。
其他
或者您可以在下面进行设置，如果要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());
}
因为在下面部署了项目结构之后。
http://localhost:8080/images/logo.png
或
http://localhost:8080/project/images/logo.png
对不起，英语。
答案 2 :(得分：1)
在应用程序属性文件中设置以下行：
spring.resources.static-locations=file:///c:/{yourWorkSpace}/{projectName}/src/main/resources/static/
这是经过测试的。
答案 3 :(得分：1)
在使用apache tomcate 9.0运行spring boot应用程序时，我遇到了同样的问题。 rightnow解决了同样的问题。 1.我在我的应用程序中添加了validation.properties文件。文件夹结构如下所示， --src / main / resources - 静态的 --application.properties --validations.properties 2.接下来，我将图像，css和js文件夹移到src / main / webapp文件夹下。 3.接下来，我已完成以下三个步骤， -清理项目 --maven安装 -更新项目 4.终于运行了应用程序，它运行成功。
答案 4 :(得分：0)
经过一些研究和重现后，我可以确认您提供的资源路径和链接是否正确。
在你的pom.xml中，你有很多＆＃34;而不是Spring-boot相关的＆＃34;依赖。如果您想进一步使用此配置，则需要遵循gipple lake's answer，因为您没有使用spring-boot-web的自动配置。
但是如果你想开箱即用的解决方案，我建议用Spring-boot相关的方法替换Spring核心依赖项。
例如使用：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
而不是：
<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>
也许您还应该添加启动启动器依赖项：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter</artifactId>
</dependency>
答案 5 :(得分：0)
这是一个干净的解决方案，可以从resources文件夹提供服务。在Spring Boot v2.1.4.RELEASE上测试。
@Configuration
public class WebConfig implements WebMvcConfigurer {
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/**")
.addResourceLocations("classpath:/static/","classpath:/image/")
.setCachePeriod(0);
}
}
您可以使它成为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（“ classpath：/ static /”，“ classpath：/ image /”，“ classpath：/ largeimage /”，“ classpath：/ pdf /”）
确保src / main / resources是源文件夹，并且您指定的文件夹位于该文件夹的正下方。
然后，您可以在html或jsp文件中简单地显示类似图像。
<img src="ok.png"/>
答案 6 :(得分：0)
只需将您的图像保留在您提供的路径中\src\main\resources\static\images\social\facebook\f_logo.jpg 并在 JSP 中加载图像时，像这样提供资源/静态的相对路径 src=" /images/social/facebook/f_logo.jpg”。这将加载图像。

您能告诉我们您的配置文件吗？
当网址未映射时，您获得了404，请向我们提供控制器。
