java springboot 配置 404页面

比较简单，直接上代码了。这里仅作记录以免后面需要用的时候忘了

package com.yutangcun.blog.config;

import org.springframework.boot.web.server.ErrorPage;
import org.springframework.boot.web.server.ErrorPageRegistrar;
import org.springframework.boot.web.server.ErrorPageRegistry;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.HttpStatus;

@Configuration
public class ErrorPageConfig implements ErrorPageRegistrar {

    @Override
    public void registerErrorPages(ErrorPageRegistry registry) {
        registry.addErrorPages(
        	new ErrorPage(HttpStatus.NOT_FOUND, "/page/404.html"), 
        	new ErrorPage(HttpStatus.INTERNAL_SERVER_ERROR,"/page/500.html")
        );
    }
}
