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：
工程结构图：
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

文件内容：
mimeType is :null
The file is a text file,this is contents:

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}
