【问题描述】：

我在管理网页上启用了“SNOOP”配置（在 Transports -> tcp 下），以查看 grizzly 在幕后所做的事情。一旦我应用了更改，下面的内容就会打印在 server.log 中。从日志中，我无法理解为什么 Grizzly 在仅更改一个参数时再次初始化它的配置（这也是 SNOOP）。我解释 Grizzly 已初始化自身的方式是在 server.log 中编写的以下行。这只是糟糕的日志记录还是我解释不正确的东西。为什么框架会在更改一个参数时再次创建 HTTP 侦听器。

WEB0169: Created **HTTP listener** [http-listener-1] on host/port

【问题讨论】：

标签： configuration glassfish-3 grizzly

【解决方案1】：

对传输的潜在更改可能会影响在传输之上运行的所有 http 侦听器。

【讨论】：

那么特别是在这种情况下，它会以影响服务的方式重新初始化侦听器吗？
AFAIR 网络层肯定会重新启动，至于 web 层 - 我不确定，最好仔细检查一下。
