银川做网站哪家好推广通

一、引入svnKit依赖

        <dependency><groupId>org.tmatesoft.svnkit</groupId><artifactId>svnkit</artifactId><version>1.9.3</version></dependency>

二、初始化仓库工厂类

本文参考来自于svnkit官网
在使用svn客户端进行各种操作时第一步需要初始化仓库工厂

/** Initializes the library to work with a repository via* different protocols.*/private static void setupLibrary() {/** For using over http:// and https://*/DAVRepositoryFactory.setup();/** For using over svn:// and svn+xxx://*/SVNRepositoryFactoryImpl.setup();/** For using over file:///*/FSRepositoryFactory.setup();}

二、使用svnkit创建本地存储仓库

try {String tgtPath = "d:/modelFiles/repos";SVNURL tgtURL = SVNRepositoryFactory.createLocalRepository( new File( tgtPath ), true , false );} catch ( SVNException e ) {//handle exception}

执行完这一段代码之后，我们可以在本地目录下发现以下目录结构

三、svn基本原子操作

    private static SVNClientManager ourClientManager;private static ISVNEventHandler myCommitEventHandler;private static ISVNEventHandler myUpdateEventHandler;private static ISVNEventHandler myWCEventHandler;/** Puts directories and files under version control scheduling them for addition* to a repository. They will be added in a next commit. Like 'svn add PATH'* command. It's done by invoking** SVNWCClient.doAdd(File path, boolean force,* boolean mkdir, boolean climbUnversionedParents, boolean recursive)** which takes the following parameters:** path - an entry to be scheduled for addition;** force - set to true to force an addition of an entry anyway;** mkdir - if true doAdd(..) creates an empty directory at path and schedules* it for addition, like 'svn mkdir PATH' command;** climbUnversionedParents - if true and the parent of the entry to be scheduled* for addition is not under version control, then doAdd(..) automatically schedules* the parent for addition, too;** recursive - if true and an entry is a directory then doAdd(..) recursively* schedules all its inner dir entries for addition as well.*/// 将文件纳入版本控制private static void addEntry(File wcPath) throws SVNException {ourClientManager.getWCClient().doAdd(wcPath, false, false, false, true);}/** Updates a working copy (brings changes from the repository into the working copy).* Like 'svn update PATH' command; It's done by invoking** SVNUpdateClient.doUpdate(File file, SVNRevision revision, boolean recursive)** which takes the following parameters:** file - a working copy entry that is to be updated;** revision - a revision to which a working copy is to be updated;** recursive - if true and an entry is a directory then doUpdate(..) recursively* updates the entire directory, otherwise - only child entries of the directory;*/// 将本地文件更新到指定版本，前提是本地有该文件的其他版本private static long update(File wcPath,SVNRevision updateToRevision, boolean isRecursive)throws SVNException {SVNUpdateClient updateClient = ourClientManager.getUpdateClient();/** sets externals not to be ignored during the update*/updateClient.setIgnoreExternals(false);/** returns the number of the revision wcPath was updated to*/return updateClient.doUpdate(wcPath, updateToRevision, isRecursive);}/** Checks out a working copy from a repository. Like 'svn checkout URL[@REV] PATH (-r..)'* command; It's done by invoking** SVNUpdateClient.doCheckout(SVNURL url, File dstPath, SVNRevision pegRevision,* SVNRevision revision, boolean recursive)** which takes the following parameters:** url - a repository location from where a working copy is to be checked out;** dstPath - a local path where the working copy will be fetched into;** pegRevision - an SVNRevision representing a revision to concretize* url (what exactly URL a user means and is sure of being the URL he needs); in other* words that is the revision in which the URL is first looked up;** revision - a revision at which a working copy being checked out is to be;** recursive - if true and url corresponds to a directory then doCheckout(..) recursively* fetches out the entire directory, otherwise - only child entries of the directory;*/// svn检出操作，即从svn仓库拉取指定版本的代码private static long checkout(SVNURL url,SVNRevision revision, File destPath, boolean isRecursive)throws SVNException {SVNUpdateClient updateClient = ourClientManager.getUpdateClient();/** sets externals not to be ignored during the checkout*/updateClient.setIgnoreExternals(false);/** returns the number of the revision at which the working copy is*/return updateClient.doCheckout(url, destPath, revision, revision, isRecursive);}/** Committs changes in a working copy to a repository. Like* 'svn commit PATH -m "some comment"' command. It's done by invoking** SVNCommitClient.doCommit(File[] paths, boolean keepLocks, String commitMessage,* boolean force, boolean recursive)** which takes the following parameters:** paths - working copy paths which changes are to be committed;** keepLocks - if true then doCommit(..) won't unlock locked paths; otherwise they will* be unlocked after a successful commit;** commitMessage - a commit log message;** force - if true then a non-recursive commit will be forced anyway;** recursive - if true and a path corresponds to a directory then doCommit(..) recursively* commits changes for the entire directory, otherwise - only for child entries of the* directory;*/// svn提交操作，将本地文件提交到svn仓库private static SVNCommitInfo commit(File wcPath, boolean keepLocks, String commitMessage)throws SVNException {/** Returns SVNCommitInfo containing information on the new revision committed* (revision number, etc.)*/return ourClientManager.getCommitClient().doCommit(new File[] { wcPath }, keepLocks,commitMessage, false, true);}/** Imports an unversioned directory into a repository location denoted by a* destination URL (all necessary parent non-existent paths will be created* automatically).

Like 'svn delete PATH' command. It's done by invoking** SVNWCClient.doDelete(File path, boolean force, boolean dryRun)** which takes the following parameters:** path - an entry to be scheduled for deletion;** force - a boolean flag which is set to true to force a deletion even if an entry* has local modifications;** dryRun - set to true not to delete an entry but to check if it can be deleted;* if false - then it's a deletion itself.*/// svn删除操作private static void delete(File wcPath, boolean force) throws SVNException {ourClientManager.getWCClient().doDelete(wcPath, force, false);}// svn删除整个工作目录操作public static SVNCommitInfo deleteDir(ISVNEditor editor , String dirPath ) throws SVNException {editor.openRoot( -1 );editor.deleteEntry( dirPath , -1 );//Closes the root directory.editor.closeDir( );return editor.closeEdit( );}// 创建指定版本分支private static SVNCommitInfo copy(SVNURL srcURL, SVNURL dstURL,SVNRevision revision,boolean isMove, String commitMessage) throws SVNException {/** SVNRevision.HEAD means the latest revision.* Returns SVNCommitInfo containing information on the new revision committed* (revision number, etc.)*/SVNCopySource[] sources = {new SVNCopySource(null, revision, srcURL)};return ourClientManager.getCopyClient().doCopy(sources , dstURL, false, false, true, commitMessage, null);}/** Called recursively to obtain all entries that make up the repository tree* repository - an SVNRepository which interface is used to carry out the* request, in this case it's a request to get all entries in the directory* located at the path parameter;* * path is a directory path relative to the repository location path (that* is a part of the URL used to create an SVNRepository instance);*  */// 打印指定版本下的文件列表信息public static void listEntries(SVNRepository repository, String path, Long version)throws SVNException {/** Gets the contents of the directory specified by path at the latest* revision (for this purpose -1 is used here as the revision number to* mean HEAD-revision) getDir returns a Collection of SVNDirEntry* elements.

四、通过原子方法实现简单svn相应操作

	// svn 工作目录private static String copyPath = "C:/modelFiles/copy/";// svn 仓库目录private static String reposPath= "C:/modelFiles/repos/";// 临时文件存放目录private static String tmpPath= "C:/modelFiles/tmp/";// 初始提交本地copyPath下文件夹到svn仓库public static long commitFile(String dirName) throws SVNException {File sourcePath = new File(copyPath+dirName);SVNURL targetURL = SVNURL.parseURIEncoded("file:///"+reposPath+dirName);committedRevision = importDirectory(sourcePath, targetURL, "上传模型文件夹 "+dirName, true).getNewRevision();return committedRevision;}// 检出指定版本到指定目录// 其中 SVNRevision 为版本对象，可以通过SVNRevision.create(1) 形式创建版本id为1的版本对象// svn版本从1开始往后迭代，为长整型，0表示最新版本用 SVNRevision.HEAD表示，其等同于 SVNRevision.create(0)public static void checkOut(String dirName,String basePath,SVNRevision svnRevision) throws SVNException {SVNURL repository = SVNURL.parseURIEncoded("file:///"+reposPath);File wcDir = new File(basePath+"/"+dirName);checkout(repository.appendPath(dirName,false), svnRevision, wcDir, true);}// svn工作目录下新增文件夹或文件后提交至svn仓库public static long commitNewFile(String dirName,String newDir) throws SVNException {// svn工作区目录File wcDir = new File(copyPath+dirName);// svn工作目录下新增的文件夹File NewDir = new File(copyPath+newDir);// 为了防止当前不是最新版本先从svn仓库更新下最新代码，其实也可以不进行这一步操作update(wcDir, SVNRevision.HEAD, true);// 将当前新增的目录加入版本控制addEntry(NewDir);// 提交至svn仓库long newRevision = commit(wcDir, false,"在 " + dirName + " 目录下新增 " + newDir).getNewRevision();log.info("在 "+dirName+" 目录下新增 "+newDir);return newRevision;}// 删除svn工作目录下某个文件夹并提交svn仓库public static long deleteFile(String dirName,String delDir) throws SVNException {File wcDir = new File(copyPath+dirName);File DelDir = new File(copyPath+delDir);delete(DelDir, false);long newRevision = commit(wcDir, false,"从 " + dirName + " 目录下删除 " + delDir).getNewRevision();log.info("从 "+dirName+" 目录下删除 "+delDir);//删除后更新下update(wcDir, SVNRevision.HEAD, true);return newRevision;}// svn删除整个工作目录操作public static void deleteFileFromRepos(String dirName){try {SVNRepository svnRepository = FSRepositoryFactory.create(SVNURL.parseURIEncoded("file:///" + reposPath));ISVNEditor editor = svnRepository.getCommitEditor( "删除目录 "+dirName , null );try {deleteDir(editor, dirName);} catch ( SVNException svne ) {editor.abortEdit( );throw svne;}} catch (Exception e) {e.printStackTrace();}}/*** @description 创建指定版本的分支*/public static Long createBranchByCopy(String dirName,Long revisionNum) {try {SVNURL srcURL = SVNURL.parseURIEncoded("file:///"+reposPath+dirName);SVNURL dstURL = SVNURL.parseURIEncoded("file:///"+reposPath+dirName+"-分支");SVNCommitInfo copyInfo = copy(srcURL,dstURL,SVNRevision.create(revisionNum),true," 创建分支：" + dirName+"-分支");checkOut(getBranchName(dirName+"-分支",copyPath);return copyInfo.getNewRevision();} catch (SVNException e) {log.info("创建分支失败："+e.getMessage());throw new RuntimeException(e);}}// 获取当前模型仓库的最新版本编号public static long getLatestRevision() throws SVNException {SVNRepository svnRepository = FSRepositoryFactory.create(SVNURL.parseURIEncoded("file:///" + reposPath));return svnRepository.getLatestRevision();}
