SpringCloud 手动命令设置

假定您具有以下HystrixCommand：

HystrixCommand<String> hystrixCommand = new HystrixCommand<String>(setter) {
	@Override
	protected String run() throws Exception {
		return someLogic();
	}
};

要传递跟踪信息，必须在HystrixCommand的Sleuth版本中包装相同的逻辑，称为TraceCommand，如以下示例所示：

TraceCommand<String> traceCommand = new TraceCommand<String>(tracer, setter) {
	@Override
	public String doRun() throws Exception {
		return someLogic();
	}
};
