java - Spring Boot 删除 Web 应用程序的 Whitelabel 错误页面

Question

我有一个 Spring Boot Web 应用程序，我将其作为 war 文件部署在 tomcat 中。我不希望向用户显示白标签错误页面。我在这方面取得了一些进展，但需要将其重定向到错误页面。

下面的代码是/error白标签错误页面是自定义错误消息。但我希望将其重定向到我的 Web 应用程序资源中的模板文件夹下可用的 error.jsp 或 error.html。我尝试将 @RestController 更改为 @Controller 但没有成功。

import org.springframework.boot.autoconfigure.web.ErrorController;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class CustomErrorController implements ErrorController {

    private static final String PATH = "/error";

    @RequestMapping(value = PATH)
    public String error() {
        return "Unexpected error has happened.Please contact administrator!!!";
    }

    @Override
    public String getErrorPath() {
        System.out.println("-- Error Page GET --");
            return "error";
    }

}
