Question

我开发了一个Web服务，我想在发生某些服务器错误时通知我（例如，除零，内存异常等）。我想知道在自定义ErrorHandler中为每个请求处理和发送此错误是否是一个好习惯？

package controllers;

import play.*;
import play.api.OptionalSourceMapper;
import play.api.UsefulException;
import play.api.routing.Router;
import play.http.DefaultHttpErrorHandler;
import play.mvc.Http.*;
import play.mvc.*;

import javax.inject.*;
import java.util.concurrent.CompletableFuture;
import java.util.concurrent.CompletionStage;

@Singleton
public class ErrorHandler extends DefaultHttpErrorHandler {

    @Inject
    public ErrorHandler(Configuration configuration, Environment environment, OptionalSourceMapper sourceMapper, Provider<Router> routes) {
        super(configuration, environment, sourceMapper, routes);
    }

    // Invoked in prod mode when a server error occurs.
    protected CompletionStage<Result> onProdServerError(RequestHeader request, UsefulException exception) {
        return CompletableFuture.completedFuture(Results.internalServerError("A server error occurred (prod): " + exception.getMessage())
                // Send email
        );
    }

    protected CompletionStage<Result> onDevServerError(RequestHeader request, UsefulException exception) {
        return CompletableFuture.completedFuture(
                Results.internalServerError("A server error occurred (dev): " + exception.getMessage())
        );
    }
}

这可能对非致命错误有用。但如果发生致命错误，这将无效。最好使用Logging和其他进程异常监控解决方案。
