如何自定义处理 Quarkus 中未找到的资源/URL? [英] How to customly handle Recourse/URLs Not Found in Quarkus?

问题描述

我对 Quarkus 非常陌生，我想知道如何覆盖提供错误日志的默认 404 页面，或者如何巧妙地将所有无法识别的 URL 重定向到 META-INF/recourses 目录中的自定义 HTML.

I'm very new to Quarkus and I will like to know how I can override default 404 page which provides the error logs or how I can neatly redirect all not recognized URLs to a custom HTML in the META-INF/recourses directory.

推荐答案

使用 quarkus 0.20+ 你可以像这样创建一个 ExceptionMapper:

Using quarkus 0.20+ you can create an ExceptionMapper like this:

import java.util.Scanner;

import javax.ws.rs.NotFoundException;
import javax.ws.rs.core.Response;
import javax.ws.rs.ext.ExceptionMapper;
import javax.ws.rs.ext.Provider;

/**
 * NotFoundExepptionMapper
 */
@Provider
public class NotFoundExeptionMapper implements ExceptionMapper<NotFoundException> {
    @Override
    public Response toResponse(NotFoundException exception) {
        String text = new Scanner(this.getClass().getResourceAsStream("/META-INF/resources/notfound.html"), "UTF-8").useDelimiter("\\A").next();
        return Response.status(404).entity(text).build();
    }
}

将页面保存在/META-INF/resources/notfound.html 上即可.

Save the page on /META-INF/resources/notfound.html and it's done.
