如何结合使用java和Braid框架示例: pigtail？

Question

我尝试在java中定义编织服务器，就像这样的repo。下面是我的BootstrapBraidService类：

@CordaService
public class BootstrapBraidService extends SingletonSerializeAsToken{
    private AppServiceHub appServiceHub;
    private BraidConfig braidConfig;
    public BootstrapBraidService(AppServiceHub appServiceHub){
        this.appServiceHub = appServiceHub;
        this.braidConfig = new BraidConfig();
        // Include a flow on the Braid server.
        braidConfig.withFlow(ExtendedStatusFlow.IssueFlow.class);
        // Include a service on the Braid server.
        braidConfig.withService("myService", new BraidService(appServiceHub));
        // The port the Braid server listens on.
        braidConfig.withPort(3001);
        // Using http instead of https.
        braidConfig.withHttpServerOptions(new HttpServerOptions().setSsl(false));
        // Start the Braid server.
        braidConfig.bootstrapBraid(this.appServiceHub,Object::notify);
    }
}

然而，节点在没有我设置情况下启动，比如端口使用默认值(8080)而不是我的设置(3001)。NodeJS服务器获取服务描述符失败：

{ Error: failed to get services descriptor from
http://localhost:8080/api/
at createHangUpError (_http_client.js:331:15)
at Socket.socketOnEnd (_http_client.js:423:23)
at emitNone (events.js:111:20)
at Socket.emit (events.js:208:7)
at endReadableNT (_stream_readable.js:1064:12)
at _combinedTickCallback (internal/process/next_tick.js:138:11)
at process._tickCallback (internal/process/next_tick.js:180:9) code: 'ECONNRESET', url: 'http://localhost:8080/api/' }

有人能告诉我如何解决这个问题吗？谢谢。

这不起作用的原因是因为BraidConfig是一个具有流畅API的不可变类，但是您的代码将它用作一个经典的可变POJO，这意味着您的任何更改都不会应用于BraidConfig。

以下代码应该可以很好地工作：

@CordaService
public class BootstrapBraidService extends SingletonSerializeAsToken{
    private AppServiceHub appServiceHub;
    private BraidConfig braidConfig;
    public BootstrapBraidService(AppServiceHub appServiceHub){
        this.appServiceHub = appServiceHub;
        this.braidConfig = new BraidConfig()
            // Include a flow on the Braid server.
            .withFlow(ExtendedStatusFlow.IssueFlow.class)
            // Include a service on the Braid server.
            braidConfig.withService(new BraidService(appServiceHub))
            // The port the Braid server listens on.
            braidConfig.withPort(3001)
            // Using http instead of https.
            braidConfig.withHttpServerOptions(new HttpServerOptions().setSsl(false));
        // Start the Braid server.
        braidConfig.bootstrapBraid(this.appServiceHub,null);
    }
}
