Question

我开始使用thorntail V4（www.thorntail.io）（以前称为wildfly swarm）来创建微服务。是的，我知道网站将其称为“概念证明”。 Thorntail船舶（www.undertow.io）。

有谁知道，如何添加或注册自定义功能HttpHandler？

如何获取链中的下一个HttpHandler以在handleRequest（）中调用它？

我目前的HttpHandler看起来像这样：

import io.undertow.server.HttpHandler;
import io.undertow.server.HttpServerExchange;

import javax.enterprise.context.ApplicationScoped;
import javax.inject.Inject;

@ApplicationScoped
public class MyCustomHttpHandler implements HttpHandler {

    @Inject
    private HttpHandler next; // how do i get the next HttpHandler?

    public MyCustomHttpHandler() {
      System.out.println("MyCustomHttpHandler.java constructed"); // never gets called. How do i register it in Thorntail?
    }

    @Override
    public void handleRequest(HttpServerExchange httpServerExchange) throws Exception {
      // never gets called :/
      System.out.println(String.format("HttpHandler next=%s", next));

      // How do i get next? Is @Inject the way to go?
    }
}

提前致谢。

顺便说一下。有人可以添加“thorntail”标签吗？我的StackOverflow-Rep不允许这样做。

您的处理程序应如下所示：

public class MyCustomHttpHandler implements HttpHandler {

    private HttpHandler next;

    public MyCustomHttpHandler(HttpHandler next) {
      this.next = next;
      System.out.println("MyCustomHttpHandler.java constructed"); // never gets called. How do i register it in Thorntail?
    }

    @Override
    public void handleRequest(HttpServerExchange httpServerExchange) throws Exception {
      // never gets called :/
      System.out.println(String.format("HttpHandler next=%s", next));

      // How do i get next? Is @Inject the way to go?
    }
}

然而，目前看来Thorntail v4并不支持在链中任意添加HttpHandler。你能在这里提出一个问题：https://github.com/thorntail/thorntail/issues
