SVNKit学习——基于Repository的操作之print repository tree、file content、repository history(四)
此篇文章同样是参考SVNKit在wiki的官方文档做的demo，每个类都可以单独运行。具体的细节都写到注释里了~
开发背景：
SVNKit版本：1.7.14 附上官网下载链接：https://www.svnkit.com/org.tmatesoft.svn_1.7.14.standalone.zip
jdk版本要求：我试了1.6版本是不行的，1.7版本的jdk没有问题。
操作：①.在官网下载SVNKit1.7.14后将lib/*.jar全部复制到工程中 ②.导入google的Gson的包，这里我用的是gson-2.2.4.jar
仓库目录结构：

具体代码：
一、显示svn仓库的树结构
package com.demo; import org.tmatesoft.svn.core.SVNDirEntry; import org.tmatesoft.svn.core.SVNNodeKind; import org.tmatesoft.svn.core.SVNURL; import org.tmatesoft.svn.core.auth.ISVNAuthenticationManager; import org.tmatesoft.svn.core.internal.io.dav.DAVRepositoryFactory; import org.tmatesoft.svn.core.io.SVNRepository; import org.tmatesoft.svn.core.io.SVNRepositoryFactory; import org.tmatesoft.svn.core.wc.SVNWCUtil; import java.io.File; import java.util.Collection; import java.util.Iterator; /** * 显示svn仓库的树结构 */ public class PrintRepositoryTree { public static void main(String[] args) throws Exception{ //1.根据访问协议初始化工厂 DAVRepositoryFactory.setup();; //2.初始化仓库 String url = "https://wlyfree-PC:8443/svn/svnkitRepository1/trunk"; SVNRepository svnRepository = SVNRepositoryFactory.create(SVNURL.parseURIEncoded(url)); //3.创建一个访问的权限 String username = "wly"; String password = "wly"; char[] pwd = password.toCharArray(); ISVNAuthenticationManager authenticationManager = SVNWCUtil.createDefaultAuthenticationManager(username,pwd); svnRepository.setAuthenticationManager(authenticationManager); /*输出仓库的根目录和UUID*/ System.out.println("Repository Root:" + svnRepository.getRepositoryRoot(true)); System.out.println("Repository UUID:" + svnRepository.getRepositoryUUID(true)); /** * 检验某个URL（可以是文件、目录）是否在仓库历史的修订版本中存在，参数：被检验的URL，修订版本，这里我们想要打印出目录树，所以要求必须是目录 * SVNNodeKind的枚举值有以下四种： * SVNNodeKind.NONE 这个node已经丢失（可能是已被删除） * SVNNodeKind.FILE 文件 * SVNNodeKind.DIR 目录 * SVNNodeKind.UNKNOW 未知，无法解析 * */ /* * 被检验的URL，本例有两种等价的写法。 * 1.不是以"/"开头的是相对于仓库驱动目录的相对目录，即svnRepository的url，在本例中是：空字符串（url目录是：https://wlyfree-PC:8443/svn/svnkitRepository1/trunk） * 2.以"/"开头的是相对于svnRepository root目录的相对目录，即svnRepository的rootUrl，在本例中是：/trunk（root目录是https://wlyfree-pc:8443/svn/svnkitRepository1） */ String checkUrl = ""; //修订版本号，-1代表一个无效的修订版本号，代表必须是最新的修订版 long revisionNum = -1; SVNNodeKind svnNodeKind = svnRepository.checkPath(checkUrl,revisionNum); if(svnNodeKind == SVNNodeKind.NONE){ System.err.println("This is no entry at " + checkUrl); System.exit(1); }else if(svnNodeKind == SVNNodeKind.FILE){ System.err.println("The entry at '" + checkUrl + "' is a file while a directory was expected."); System.exit(1); }else{ System.err.println("SVNNodeKind的值：" + svnNodeKind); } //打印出目录树结构 listEntries(svnRepository,checkUrl); //打印最新修订版的版本号 System.err.println("最新修订版版本号：" + svnRepository.getLatestRevision()); } private static void listEntries(SVNRepository svnRepository,String path) throws Exception{ System.err.println("path:" + path); Collection entry = svnRepository.getDir(path, -1 ,null,(Collection)null); Iterator iterator = entry.iterator(); while(iterator.hasNext()){ SVNDirEntry svnDirEntry = (SVNDirEntry)iterator.next(); System.out.println("path:" + "/" + (path.equals("") ? "" : path + "/") + svnDirEntry.getName() + ",(author:" + svnDirEntry.getAuthor() + ",revision:" + svnDirEntry.getRevision() + ",date:" + svnDirEntry.getDate() + ")"); if(svnDirEntry.getKind() == SVNNodeKind.DIR){ String tempPath = (path.equals("") ? svnDirEntry.getName() : path + "/" + svnDirEntry.getName()) ; listEntries(svnRepository,tempPath); } } } }
运行效果：
Repository Root:https://wlyfree-pc:8443/svn/svnkitRepository1 Repository UUID:62e76a57-4b9a-d34b-92c0-4551f8669da5 SVNNodeKind的值：dir path: path:test path:/init1.txt,(author:wly,revision:8,date:Tue Nov 29 15:36:47 CST 2016) path:/init2.txt,(author:wly,revision:8,date:Tue Nov 29 15:36:47 CST 2016) path:/test,(author:wly,revision:10,date:Tue Dec 06 13:50:53 CST 2016) path:/test/init11.txt,(author:wly,revision:10,date:Tue Dec 06 13:50:53 CST 2016) path:/test/init22.txt,(author:wly,revision:9,date:Tue Dec 06 12:13:42 CST 2016) path:/test/test2,(author:wly,revision:9,date:Tue Dec 06 12:13:42 CST 2016) path:test/test2 path:/test/test2/init111.txt,(author:wly,revision:9,date:Tue Dec 06 12:13:42 CST 2016) path:/test/test2/init222.txt,(author:wly,revision:9,date:Tue Dec 06 12:13:42 CST 2016) 最新修订版版本号：10 Process finished with exit code 0
二、打印文件内容
获取文件的类型，如果文件是二进制文件，则只输出文件属性;如果文件是一个文本文件，输出文件属性和文件内容
package com.demo; import com.google.gson.Gson; import org.tmatesoft.svn.core.*; import org.tmatesoft.svn.core.auth.ISVNAuthenticationManager; import org.tmatesoft.svn.core.internal.io.dav.DAVRepositoryFactory; import org.tmatesoft.svn.core.io.SVNRepository; import org.tmatesoft.svn.core.io.SVNRepositoryFactory; import org.tmatesoft.svn.core.wc.SVNWCUtil; import java.io.ByteArrayOutputStream; import java.util.Iterator; import java.util.Map; /** * 获取文件的类型，如果文件是二进制文件，则只输出文件属性;如果文件是一个文本文件，输出文件属性和文件内容 */ public class PrintFileContent { public static void main(String[] args) throws Exception { //===========================前面几步和打印树是一样的START=================================== //1.根据访问协议初始化工厂 DAVRepositoryFactory.setup();; //2.初始化仓库 String url = "https://wlyfree-PC:8443/svn/svnkitRepository1/trunk"; SVNRepository svnRepository = SVNRepositoryFactory.create(SVNURL.parseURIEncoded(url)); //3.创建一个访问的权限 String username = "wly"; String password = "wly"; char[] pwd = password.toCharArray(); ISVNAuthenticationManager authenticationManager = SVNWCUtil.createDefaultAuthenticationManager(username,pwd); svnRepository.setAuthenticationManager(authenticationManager); //===========================前面几步和打印树是一样的END=================================== //这里我们要读取的是其中的一个文件 String filePath = "test/init11.txt"; //修订版本号，-1代表一个无效的修订版本号，代表必须是最新的修订版 long revisionNum = -1; SVNNodeKind svnNodeKind = svnRepository.checkPath(filePath,revisionNum); if(svnNodeKind == SVNNodeKind.NONE){ System.err.println("This is no entry at " + filePath); System.exit(1); }else if(svnNodeKind == SVNNodeKind.DIR){ System.err.println("The entry at '" + filePath + "' is a directory while a file was expected."); System.exit(1); }else{ System.err.println("SVNNodeKind的值：" + svnNodeKind); } ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream(); SVNProperties svnProperties = new SVNProperties(); //若svnProperties对象非空，使用vnProperties属性接收文件的属性 svnRepository.getFile(filePath,-1,svnProperties ,byteArrayOutputStream); /* * 输出文件属性 */ System.err.println("文件属性："); Map<String,SVNPropertyValue> svnPropertiesMap = svnProperties.asMap(); Iterator<String> it = svnPropertiesMap.keySet().iterator(); while(it.hasNext()){ String key = it.next(); System.err.println(key + " : " + svnPropertiesMap.get(key)); } //序列化看下svnProperrties中的数据 Gson gson = new Gson(); System.err.println(gson.toJson(svnProperties)); /* * 文件是否是文本类型的文件，文本类型文件输出文件内容 */ System.err.println("文件内容："); String mimeType = svnProperties.getStringValue(SVNProperty.MIME_TYPE); System.err.println("mimeType is :" + mimeType); boolean isTextType = SVNProperty.isTextMimeType(mimeType); if(isTextType){ System.err.println("The file is a text file,this is contents:"); byteArrayOutputStream.writeTo(System.err); }else{ System.err.println("The file is not a text file,we can't read content of it."); } } }
运行效果：
SVNNodeKind的值：file 文件属性： svn:entry:uuid : 62e76a57-4b9a-d34b-92c0-4551f8669da5 svn:entry:revision : 10 svn:entry:committed-date : 2016-12-06T05:50:53.160008Z svn:wc:ra_dav:version-url : /svn/svnkitRepository1/!svn/ver/10/trunk/test/init11.txt svn:entry:checksum : 8217e71c38f5c42e3fd4e8ac8dc75c4f svn:entry:committed-rev : 10 svn:entry:last-author : wly {"myProperties":{"svn:entry:uuid":{"myValue":"62e76a57-4b9a-d34b-92c0-4551f8669da5"},"svn:entry:revision":{"myValue":"10"},"svn:entry:committed-date":{"myValue":"2016-12-06T05:50:53.160008Z"},"svn:wc:ra_dav:version-url":{"myValue":"/svn/svnkitRepository1/!svn/ver/10/trunk/test/init11.txt"},"svn:entry:checksum":{"myValue":"8217e71c38f5c42e3fd4e8ac8dc75c4f"},"svn:entry:committed-rev":{"myValue":"10"},"svn:entry:last-author":{"myValue":"wly"}}} 文件内容： mimeType is :null The file is a text file,this is contents: init aa bb cc dd 11 22 33 44 Process finished with exit code 0
三、打印历史记录
package com.demo; import com.google.gson.Gson; import org.tmatesoft.svn.core.SVNLogEntry; import org.tmatesoft.svn.core.SVNLogEntryPath; import org.tmatesoft.svn.core.SVNURL; import org.tmatesoft.svn.core.auth.ISVNAuthenticationManager; import org.tmatesoft.svn.core.internal.io.dav.DAVRepositoryFactory; import org.tmatesoft.svn.core.io.SVNRepository; import org.tmatesoft.svn.core.io.SVNRepositoryFactory; import org.tmatesoft.svn.core.wc.SVNWCUtil; import java.util.Collection; import java.util.Iterator; import java.util.Set; /** * 打印历史记录 */ public class PrintRepositoryHistory { public static void main(String[] args) throws Exception{ //===========================前面几步和打印树是一样的START=================================== //1.根据访问协议初始化工厂 DAVRepositoryFactory.setup();; //2.初始化仓库 String url = "https://wlyfree-PC:8443/svn/svnkitRepository1/trunk"; SVNRepository svnRepository = SVNRepositoryFactory.create(SVNURL.parseURIEncoded(url)); //3.创建一个访问的权限 String username = "wly"; String password = "wly"; char[] pwd = password.toCharArray(); ISVNAuthenticationManager authenticationManager = SVNWCUtil.createDefaultAuthenticationManager(username,pwd); svnRepository.setAuthenticationManager(authenticationManager); //===========================前面几步和打印树是一样的END=================================== long startVersion = 10; long endVersion = 8; /* * 参数： * 1.接收日志 * 2.接收history对象，每个修订版的信息都代表一个SVNLogEntry对象。如果我们不需要传入一个已经存在的history对象，就传入null值 * 3.开始修订版本号，0、-1代表最新版本 * 4.结束修订版本号，0、-1代表最新版本 * 5.如果需要打印改变路径的信息，则设置为true。会使用每个SVNLogEntry对象记录改变路径的信息getchangedpaths()会返回一个Map<String改变路径,SVNLogEntryPath> 对象 * 6.strictNode设置为true，复制history的时候不会跳过每个path的修订版日志 */ Collection logEntries = svnRepository.log(new String[]{""}, null,8,8,true,true); Gson gson = new Gson(); if(logEntries != null){ Iterator it = logEntries.iterator(); while (it.hasNext()){ SVNLogEntry svnLogEntry = (SVNLogEntry)it.next(); System.err.println("序列化数据：" + gson.toJson(svnLogEntry)); if(svnLogEntry.getChangedPaths().size() > 0){ System.err.println("Change path:"); Set changePathSet = svnLogEntry.getChangedPaths().keySet(); if(changePathSet != null && changePathSet.size() > 0){ for(Iterator changePaths = changePathSet.iterator();changePaths.hasNext();){ SVNLogEntryPath svnLogEntryPath = svnLogEntry.getChangedPaths().get(changePaths.next()); System.err.println(gson.toJson(svnLogEntryPath)); } } } } } } }
运行效果：
序列化数据：{"myRevision":8,"myChangedPaths":{"/trunk/init1.txt":{"myPath":"/trunk/init1.txt","myType":"A","myCopyRevision":-1,"myNodeKind":{"myID":1}},"/trunk/init2.txt":{"myPath":"/trunk/init2.txt","myType":"A","myCopyRevision":-1,"myNodeKind":{"myID":1}}},"myRevisionProperties":{"myProperties":{"svn:log":{"myValue":"初始化导入目录-myRepository1"},"svn:author":{"myValue":"wly"},"svn:date":{"myValue":"2016-11-29T07:36:47.737654Z"}}},"myHasChildren":false,"myIsSubtractiveMerge":false,"myIsNonInheritable":false} Change path: {"myPath":"/trunk/init1.txt","myType":"A","myCopyRevision":-1,"myNodeKind":{"myID":1}} {"myPath":"/trunk/init2.txt","myType":"A","myCopyRevision":-1,"myNodeKind":{"myID":1}} Process finished with exit code 0
