做这个小项目的目的主要也是为了项目小组成员能更好地一致工作。现在一般做项目都是通过CVS将人家的代码更新下来，在自己的机子上把应用给跑起来，但如果我们做的是web开发，那么可以试着将大家各自的“服务器”统一到一台服务器上，比如，CVS提交上192.168.0.1上后，打开网页192.168.0.1能自动体现出来。现在的问题是，如果简单在服务器上把IIS或者TOMCAT之类的目录指到CVS仓库上是没用的，因为存在CVS仓库上的文件都是经过CVS的方式储存的，拿出来不能直接跑起来的。于是我就有了做这个自动化工作的想法。

CVS提交——》服务器监控到CVS仓库变化——》下载更新到IIS或者TOMCAT指定的目录——》小组成员刷新网页
| |
|________________________小组成员所需做的_______________________________________|
这里有2个重点所以，一、监控文件变化 二、CVS操作
对于CVS操作，JAVA用javacvs开源项目可以非常轻松搞定，但是对于文件的变化监控，考虑到效率java非常难做，因为java只能主动去提取文件系统的变化，而不能让文件系统的变化来通知java，所以这个while循环只能依赖线程的sleep。 所幸的是，windows API给我们提供了一套非常好的回调机制用来监控文件系统
#include <windows.h>#include <stdlib.h>#include <stdio.h>#include <tchar.h>void RefreshDirectory(LPTSTR);void RefreshTree(LPTSTR);void WatchDirectory(LPTSTR lpDir){
DWORD dwWaitStatus; HANDLE dwChangeHandles[2]; TCHAR lpDrive[4]; TCHAR lpFile[_MAX_FNAME]; TCHAR lpExt[_MAX_EXT]; _tsplitpath(lpDir, lpDrive, NULL, lpFile, lpExt); lpDrive[2] = (TCHAR)'/'; lpDrive[3] = (TCHAR)''; // Watch the directory for file creation and deletion. dwChangeHandles[0] = FindFirstChangeNotification( lpDir, // directory to watch FALSE, // do not watch subtree FILE_NOTIFY_CHANGE_FILE_NAME); // watch file name changes if (dwChangeHandles[0] == INVALID_HANDLE_VALUE) ExitProcess(GetLastError()); // Watch the subtree for directory creation and deletion. dwChangeHandles[1] = FindFirstChangeNotification( lpDrive, // directory to watch TRUE, // watch the subtree FILE_NOTIFY_CHANGE_DIR_NAME); // watch dir. name changes if (dwChangeHandles[1] == INVALID_HANDLE_VALUE) ExitProcess(GetLastError()); // Change notification is set. Now wait on both notification // handles and refresh accordingly. while (TRUE) { 
// Wait for notification. dwWaitStatus = WaitForMultipleObjects(2, dwChangeHandles, FALSE, INFINITE); switch (dwWaitStatus) { case WAIT_OBJECT_0: // A file was created or deleted in the directory. // Refresh this directory and restart the notification. RefreshDirectory(lpDir); if ( FindNextChangeNotification( dwChangeHandles[0]) == FALSE ) ExitProcess(GetLastError()); break; case WAIT_OBJECT_0 + 1: // A directory was created or deleted in the subtree. // Refresh the tree and restart the notification. RefreshTree(lpDrive); if (FindNextChangeNotification( dwChangeHandles[1]) == FALSE) ExitProcess(GetLastError()); break; default: ExitProcess(GetLastError()); } }}void RefreshDirectory(LPTSTR lpDir){ _tprintf(TEXT("Refresh the directory (%s). "), lpDir);}void RefreshTree(LPTSTR lpDrive){ _tprintf(TEXT("Refresh the directory tree (%s). "), lpDrive);}嗯……看来完全符合我们的要求。好了，现在开始从JAVA端开始写
JNI的文章网上都有，一般都是编写native接口，生产.h头文件，再写.cpp实现，编译成DLL……
let‘s go……
package wxy.tool.filewatcher;public final class FileWatcherNative { static { System.loadLibrary("FileWatcher"); } /** * HANDLE FindFirstChangeNotification( LPCTSTR lpPathName, BOOL * bWatchSubtree, DWORD dwNotifyFilter ); * 用来得到句柄 */ static native long FindFirstChangeNotification(String lpPathName, boolean bWatchSubtree, int dwNotifyFilter) throws Exception; /** * BOOL FindNextChangeNotification( HANDLE hChangeHandle ); * 开始监控句柄 */ static native void FindNextChangeNotification(long hChangeHandle) throws Exception; /** * BOOL FindCloseChangeNotification( HANDLE hChangeHandle ); * 关闭监控 */ static native void FindCloseChangeNotification(long hChangeHandle) throws Exception; /** * DWORD WaitForSingleObject( HANDLE hHandle, DWORD dwMilliseconds ); * * 等待这个句柄的反应 * * 注意，这里我们要让它无穷等待，所以dwMilliseconds要设置为无穷，但是java里的无穷 * 与c里的无穷是不一样的，java里，int类型的正无穷代表2的31次方-1，负无穷代表 * -2的31次方，有正负之分，而dwMilliseconds数据类型为unsigned long仅仅代表了正数 * 概念，所以我们表示成0xFFFFFFFF就可以了，其实相当于-1，这里我们干脆把这个类型定义死 */ static native int WaitForSingleObject(long hHandle, int dwTimeoutMilliseconds); static final int INFINITE = 0xFFFFFFFF; /** * 下面三个参数都是代表WaitForSingleObject的返回值，第二个是正常返回的 */ static final int WAIT_ABANDONED = 0x00000080; static final int WAIT_OBJECT_0 = 0x00000000; static final int WAIT_TIMEOUT = 0x00000102;}接着我们编译好，用javah生成.h文件
把JDK里的inlude 文件内的文件包含到工程里，引入刚才生成的头文件
头文件代码是自动生成的，如下：
/* DO NOT EDIT THIS FILE - it is machine generated */#include "jni.h"/* Header for class wxy_tool_filewatcher_FileWatcherNative */#ifndef _Included_wxy_tool_filewatcher_FileWatcherNative#define _Included_wxy_tool_filewatcher_FileWatcherNative#ifdef __cplusplusextern "C" {#endif#undef wxy_tool_filewatcher_FileWatcherNative_INFINITE#define wxy_tool_filewatcher_FileWatcherNative_INFINITE -1L#undef wxy_tool_filewatcher_FileWatcherNative_WAIT_ABANDONED#define wxy_tool_filewatcher_FileWatcherNative_WAIT_ABANDONED 128L#undef wxy_tool_filewatcher_FileWatcherNative_WAIT_OBJECT_0#define wxy_tool_filewatcher_FileWatcherNative_WAIT_OBJECT_0 0L#undef wxy_tool_filewatcher_FileWatcherNative_WAIT_TIMEOUT#define wxy_tool_filewatcher_FileWatcherNative_WAIT_TIMEOUT 258L/* * Class: wxy_tool_filewatcher_FileWatcherNative * Method: FindFirstChangeNotification * Signature: (Ljava/lang/String;ZI)J */JNIEXPORT jlong JNICALL Java_wxy_tool_filewatcher_FileWatcherNative_FindFirstChangeNotification (JNIEnv *, jclass, jstring, jboolean, jint);/* * Class: wxy_tool_filewatcher_FileWatcherNative * Method: FindNextChangeNotification * Signature: (J)V */JNIEXPORT void JNICALL Java_wxy_tool_filewatcher_FileWatcherNative_FindNextChangeNotification (JNIEnv *, jclass, jlong);/* * Class: wxy_tool_filewatcher_FileWatcherNative * Method: FindCloseChangeNotification * Signature: (J)V */JNIEXPORT void JNICALL Java_wxy_tool_filewatcher_FileWatcherNative_FindCloseChangeNotification (JNIEnv *, jclass, jlong);/* * Class: wxy_tool_filewatcher_FileWatcherNative * Method: WaitForSingleObject * Signature: (JI)I */JNIEXPORT jint JNICALL Java_wxy_tool_filewatcher_FileWatcherNative_WaitForSingleObject (JNIEnv *, jclass, jlong, jint);#ifdef __cplusplus}#endif#endif下面是自己编写的 filewatcher.cpp
// filewatcher.cpp : 定义 DLL 应用程序的入口点。//#include "stdafx.h"#include "wxy_tool_filewatcher_FileWatcherNative.h"#ifdef _MANAGED#pragma managed(push, off)#endifBOOL APIENTRY DllMain( HMODULE hModule, DWORD ul_reason_for_call, LPVOID lpReserved ){ return TRUE;}JNIEXPORT jlong JNICALL Java_wxy_tool_filewatcher_FileWatcherNative_FindFirstChangeNotification(JNIEnv* javaEnv, jclass, jstring javaPathName, jboolean javaWatchSubtree, jint javaNotifyFilter){ /* * 将java的数据类型转换过来， GetStringChars ReleaseStringChars要注意配对出现 */ const jchar* lpJavaPathName = javaEnv->GetStringChars(javaPathName, NULL); LPCTSTR lpPathName = (LPCTSTR) lpJavaPathName; BOOL bWatchSubtree = (BOOL)javaWatchSubtree; DWORD dwNotifyFilter = (DWORD)javaNotifyFilter; HANDLE handle = FindFirstChangeNotification(lpPathName, bWatchSubtree, dwNotifyFilter); if (handle == INVALID_HANDLE_VALUE || handle == (HANDLE)ERROR_INVALID_FUNCTION) { DWORD errorCode = GetLastError(); jclass exceptionClass = javaEnv->FindClass("java/lang/Exception"); javaEnv->ThrowNew(exceptionClass, "DLL Throws a Exception in FindFirstChangeNotification"); } javaEnv->ReleaseStringChars(javaPathName, lpJavaPathName); return (jlong)handle;}JNIEXPORT void JNICALL Java_wxy_tool_filewatcher_FileWatcherNative_FindNextChangeNotification(JNIEnv *javaEnv, jclass, jlong handle){ if (!

可以了，我们开始做单元测试吧：
package wxy.tool.filewatcher;import static org.junit.Assert.*;import org.junit.Test;public class FileWatcherNativeTest { private long handle; @Test public void testFindFirstChangeNotification() throws Exception { handle = FileWatcherNative.FindFirstChangeNotification( "d:/", true, 0x00000010); } @Test public void testFindNextChangeNotification()throws Exception{ handle = FileWatcherNative.FindFirstChangeNotification( "d:/", true, 0x00000010); FileWatcherNative.FindNextChangeNotification(handle); } @Test public void testFindCloseChangeNotification() throws Exception{ handle = FileWatcherNative.FindFirstChangeNotification( "d:/", true, 0x00000010); FileWatcherNative.FindCloseChangeNotification(handle); } @Test public void testWaitForSingleObject() throws Exception{ handle = FileWatcherNative.FindFirstChangeNotification( "d:/", true, 0x00000010); FileWatcherNative.FindNextChangeNotification(handle); int returnState = FileWatcherNative.WaitForSingleObject( handle, FileWatcherNative.INFINITE); assertEquals(FileWatcherNative.WAIT_OBJECT_0, returnState); }}
可以发现，在第一个方法那里停住了，也就是说进入了监控状态，我们在D盘下写入一个文件后，可以发现测试自动全部完成。
监控的状态如下
/** 当文件名变更 */ public static final int FILE_NOTIFY_CHANGE_FILE_NAME = 0x00000001; /** 当目录名字变更 */ public static final int FILE_NOTIFY_CHANGE_DIR_NAME = 0x00000002; /** 当文件属性变更 */ public static final int FILE_NOTIFY_CHANGE_ATTRIBUTES = 0x00000004; /** 当文件大小变更 */ public static final int FILE_NOTIFY_CHANGE_SIZE = 0x00000008; /** 当发现有写入数据行为 */ public static final int FILE_NOTIFY_CHANGE_LAST_WRITE = 0x00000010; /** 当有访问发生 */ public static final int FILE_NOTIFY_CHANGE_LAST_ACCESS = 0x00000020; /** 当有文件创建 */ public static final int FILE_NOTIFY_CHANGE_CREATION = 0x00000040; /** 当安全性发生变更 */ public static final int FILE_NOTIFY_CHANGE_SECURITY = 0x00000100; /** 全部监控！！ */ public static final int FILE_NOTIFY_CHANGE_ALL = 0x000000FF;
