如何将Spring Boot的“Whitelabel错误页”替换为空白页？

Question

Whitelabel Error Page

This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Not Found, status=404)

我想本教程描述了该怎么做：https://www.baeldung.com/spring-boot-custom-error-page

本质上，您可以这样做：

@Controller
public class MyErrorController implements org.springframework.boot.web.servlet.error.ErrorController {

    @RequestMapping("/error")
    public String handleError() {
        //do something like logging
        return "error";
    }

    @Override
    public String getErrorPath() {
        return "/error";
    }
}

然后确保默认行为被关闭。

@EnableAutoConfiguration(exclude = {ErrorMvcAutoConfiguration.class})
@SpringBootApplication
public class Application {

    public static void main(String... args) {
        SpringApplication.run(Application.class, args);
    }

}
