enoeht的Java源码系列之处理配置文件‖
| Listener = org.kyle. | net.svr.sample.SampleListene | rImpl |
| ServerAddress = 127.0.0.1 |
| ListeningPort = 80 |

| StatelessService = true |
| LogLevel = ALL |
| LogPath = server.log |
| 在这里提供了一个处理这种配置文件的类的源代码。 |

| 使用方法： |
| String cfgFile ="server.cfg"; |
| GenProfile m_env = new GenProfil | e( cfgFile ); |
| 这样在程序中就可以使 容了。 | 用例如m_env. getServerAddres | s()等方法取得配置文件的相应内 |
