java - 避免 "No mapping found for HTTP request with URI"或 catch-all Controller

Question

避免以下警告的最佳方法是什么？

o.s.web.servlet.PageNotFound : No mapping found for HTTP request with URI [......]

我尝试添加一个包罗万象的 Controller ，如下所示:

@Controller
class CatchAllController {
    @RequestMapping(value = "/**")
    public ResponseEntity<?> catchAll() {
        return new ResponseEntity<>(HttpStatus.NOT_FOUND);
    }
}

但由于某种原因，静态内容(即src/main/resources/static/)也被 Controller 捕获，因此无法访问。

另一方面，我不希望这些警告出现在日志中，因为客户端可能会访问随机 URI，而我不希望收到相关通知。

Answer 1

On the other hand, I don't want these warnings to appear in the logs since clients may access random URI and I don't want to be notified about it.

然后只需禁用记录这些警告的记录器即可。

截至Spring 5.1.4.RELEASE ，这些是通过这些成员从 DispatcherServlet 记录的

/** Log category to use when no mapped handler is found for a request. */
public static final String PAGE_NOT_FOUND_LOG_CATEGORY = "org.springframework.web.servlet.PageNotFound";

/** Additional logger to use when no mapped handler is found for a request. */
protected static final Log pageNotFoundLogger = LogFactory.getLog(PAGE_NOT_FOUND_LOG_CATEGORY);

使用 Logback，您可以声明类似的内容

<logger name="org.springframework.web.servlet.PageNotFound" level="ERROR">
   ...
</logger>

同样，使用 log4j2，您也可以这样做

<Logger name="org.springframework.web.servlet.PageNotFound" level="ERROR">
   ...
</Logger>
