春季启动应用程序的嵌入式Tomcat目录列表 [英] Embedded Tomcat directory listing for spring-boot application
问题描述
我有一个带有嵌入式Tomcat的spring boot应用程序. 我想公开一些图片文件和通过tomcat目录列表从其他位置复制文件夹.所以我在名为
I have a spring boot application with embedded Tomcat. I wanted to expose some images files & folders from a different location via tomcat directory listing. So I added the below in my configuration file called
public class AppConfig extends WebMvcConfigurerAdapter
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/images/**").addResourceLocations("file:///xxx/yyy/images/");
}
}
如果知道名称,我现在可以访问单个图像.
I can now access individual image(s), if I know the name.
示例:localhost:8080/images/file.jpg.
Example: localhost:8080/images/file.jpg.
但是由于默认情况下目录列表为假,所以我无法通过"localhost:8080/images/"访问图像列表以了解所有可用图像.
But since the directory listing is false by default, I can't access the images listing through "localhost:8080/images/" to know the all the available images.
我尝试了以下选项来添加列表,但是没有用.
I tried the below option to add the listings as well, but did not work.
public class MyApplication implements ServletContextInitializer{
public static void main(String[] args) {
SpringApplication.run(MyApplication.class, args);
}
@Override
public void onStartup(ServletContext servletContext) throws ServletException {
servletContext.setInitParameter("listings", "true");
}
}

已针对Spring 2.1更新
Updated for Spring 2.1

String parentFolder = tomcatBaseDir.substring(0,tomcatBaseDir.lastIndexOf("\\"));
String childFolder = tomcatBaseDir.substring(tomcatBaseDir.lastIndexOf("\\") + 1);
context.setDocBase(parentFolder);
Wrapper defServlet = (Wrapper) context.findChild("default");

};
factory.addContextCustomizers(tomcatContextCustomizer);
}
}
