Question

我需要一个只匹配任何路径级别图像的请求映射器。

例如，它必须匹配;

http://localhost:8080/filename.jpg
http://localhost:8080/figs/filename.jpg

我尝试了正则表达式和非正则表达式;

@RequestMapping(value = "{reg:(?:\\w|\\W)+\\.(?:jpg|bmp|gif|jpeg|png|webp)$}", method = RequestMethod.GET)

但是，它与http://localhost:8080/filename.jpg匹配，但与http://localhost:8080/figs/filename.jpg或http://localhost:8080/anypathlevelNtimes/ figs/filename.jpg不匹配

它如何与所有路径级别匹配，文件扩展名只是图像。

编辑：现在没关系

@RequestMapping(value = {"/**/{extension:(?:\\w|\\W)+\\.(?:jpg|bmp|gif|jpeg|png|webp)$}"}, method = RequestMethod.GET)

Answer 1

OP提出的解决方案：

@RequestMapping( //
       value  = {"/**/{extension:(?:\\w|\\W)+\\.(?:jpg|bmp|gif|jpeg|png|webp)$}"}, //
       method = RequestMethod.GET //
)

Answer 2

@RequestMapping("/spring-web/{symbolicName:[a-z-]+}-{version:\\d\\.\\d\\.\\d}{extension:\\.[a-z]+}")
public void handle(@PathVariable String version, @PathVariable String extension) {
    // ...
}
