Java 在Vert.x中呈现Thymeleaf模板时引发ClosedByInterruptException

我想征求关于在Vert.x中编写模板处理代码的最佳方法的建议，以避免

closedbyinterrupexception

。我们处理的模板并不复杂，但中建议的方法偶尔会产生下面提到的异常

Vert.x代码如下所示：

engine.getThymeleafTemplateEngine（）.clearTemplateCache（）；
fileKeyObservable.toList（）.doError（e->LOGGER.error（“无法获取旅程文档文件”，e））.subscribe（fileKeys->{
routingContext.put（“yamlFiles”，generateYamlFiles（filekey））；
render（routingContext，“templates/index.html”，参考资料->{
if（resource.successed（））{
debug（“成功生成模板”）；
routingContext.response（）.putHeader（内容类型、文本HTML值）.end（resource.result（））；
}否则{
错误（“未能呈现模板，原因：{}”，resource.cause（））；
routingContext.fail（resource.cause（））；
}
});
});

下面是异常堆栈跟踪：

有没有更好的方法来编写模板处理代码，这样我们就不会出现线程中断异常？Vert.x示例代码似乎建议使用与我们相同的方法

错误的不是Vert.x代码示例。系统中发生了一些情况，因此在通道上执行某些IO操作时，处理模板的线程被中断（因此出现ClosedByInterruptException）。我建议您在GitHub上创建一个小型的复制器，并在Vert.x用户论坛上共享。您能告诉我您在哪里调用提供的代码片段吗？什么是

fileKeyObservable

observable对象，您的index.html是什么样子的？
