oge rgs 新版本 val 技術分享 array class and 解析 
此篇文章同樣是參考SVNKit在wiki的官方文檔做的demo，每個類都可以單獨運行。具體的細節都寫到註釋裏了~
開發背景：
SVNKit版本：1.7.14 附上官網下載鏈接：https://www.svnkit.com/org.tmatesoft.svn_1.7.14.standalone.zip
jdk版本要求：我試了1.6版本是不行的，1.7版本的jdk沒有問題。
操作：①.在官網下載SVNKit1.7.14後將lib/*.jar全部復制到工程中 ②.導入google的Gson的包，這裏我用的是gson-2.2.4.jar
倉庫目錄結構：

具體代碼：
一、顯示svn倉庫的樹結構
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;
/**
* 顯示svn倉庫的樹結構
*/
public class PrintRepositoryTree {
public static void main(String[] args) throws Exception{
//1.根據訪問協議初始化工廠
DAVRepositoryFactory.setup();;
//2.初始化倉庫
String url = "https://wlyfree-PC:8443/svn/svnkitRepository1/trunk";
SVNRepository svnRepository = SVNRepositoryFactory.create(SVNURL.parseURIEncoded(url));
//3.創建一個訪問的權限
String username = "wly";
String password = "wly";
char[] pwd = password.toCharArray();
ISVNAuthenticationManager authenticationManager = SVNWCUtil.createDefaultAuthenticationManager(username,pwd);
svnRepository.setAuthenticationManager(authenticationManager);
/*輸出倉庫的根目錄和UUID*/
System.out.println("Repository Root:" + svnRepository.getRepositoryRoot(true));
System.out.println("Repository UUID:" + svnRepository.getRepositoryUUID(true));
/**
* 檢驗某個URL（可以是文件、目錄）是否在倉庫歷史的修訂版本中存在，參數：被檢驗的URL，修訂版本，這裏我們想要打印出目錄樹，所以要求必須是目錄
* SVNNodeKind的枚舉值有以下四種：
* SVNNodeKind.NONE 這個node已經丟失（可能是已被刪除）
* SVNNodeKind.FILE 文件
* SVNNodeKind.DIR 目錄
* SVNNodeKind.UNKNOW 未知，無法解析
* */
/*
* 被檢驗的URL，本例有兩種等價的寫法。
* 1.不是以"/"開頭的是相對於倉庫驅動目錄的相對目錄，即svnRepository的url，在本例中是：空字符串（url目錄是：https://wlyfree-PC:8443/svn/svnkitRepository1/trunk）
* 2.以"/"開頭的是相對於svnRepository root目錄的相對目錄，即svnRepository的rootUrl，在本例中是：/trunk（root目錄是https://wlyfree-pc:8443/svn/svnkitRepository1）
*/
String checkUrl = "";
//修訂版本號，-1代表一個無效的修訂版本號，代表必須是最新的修訂版
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);
}
//打印出目錄樹結構
listEntries(svnRepository,checkUrl);
//打印最新修訂版的版本號
System.err.println("最新修訂版版本號：" + 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);
}
}
}
}
運行效果：
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) 最新修訂版版本號：10 Process finished with exit code 0
二、打印文件內容
獲取文件的類型，如果文件是二進制文件，則只輸出文件屬性;如果文件是一個文本文件，輸出文件屬性和文件內容
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;
/**
* 獲取文件的類型，如果文件是二進制文件，則只輸出文件屬性;如果文件是一個文本文件，輸出文件屬性和文件內容
*/
public class PrintFileContent {
public static void main(String[] args) throws Exception {
//===========================前面幾步和打印樹是一樣的START===================================
//1.根據訪問協議初始化工廠
DAVRepositoryFactory.setup();;
//2.初始化倉庫
String url = "https://wlyfree-PC:8443/svn/svnkitRepository1/trunk";
SVNRepository svnRepository = SVNRepositoryFactory.create(SVNURL.parseURIEncoded(url));
//3.創建一個訪問的權限
String username = "wly";
String password = "wly";
char[] pwd = password.toCharArray();
ISVNAuthenticationManager authenticationManager = SVNWCUtil.createDefaultAuthenticationManager(username,pwd);
svnRepository.setAuthenticationManager(authenticationManager);
//===========================前面幾步和打印樹是一樣的END===================================
//這裏我們要讀取的是其中的一個文件
String filePath = "test/init11.txt";
//修訂版本號，-1代表一個無效的修訂版本號，代表必須是最新的修訂版
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對象非空，使用vnProperties屬性接收文件的屬性
svnRepository.getFile(filePath,-1,svnProperties ,byteArrayOutputStream);
/*
* 輸出文件屬性
*/
System.err.println("文件屬性：");
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中的數據
Gson gson = new Gson();
System.err.println(gson.toJson(svnProperties));
/*
* 文件是否是文本類型的文件，文本類型文件輸出文件內容
*/
System.err.println("文件內容：");
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.");
}
}
}
運行效果：
SVNNodeKind的值：file
文件屬性：
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"}}}
文件內容：
mimeType is :null
The file is a text file,this is contents:
init
aa

三、打印歷史記錄
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;
/**
* 打印歷史記錄
*/
public class PrintRepositoryHistory {
public static void main(String[] args) throws Exception{
//===========================前面幾步和打印樹是一樣的START===================================
//1.根據訪問協議初始化工廠
DAVRepositoryFactory.setup();;
//2.初始化倉庫
String url = "https://wlyfree-PC:8443/svn/svnkitRepository1/trunk";
SVNRepository svnRepository = SVNRepositoryFactory.create(SVNURL.parseURIEncoded(url));
//3.創建一個訪問的權限
String username = "wly";
String password = "wly";
char[] pwd = password.toCharArray();
ISVNAuthenticationManager authenticationManager = SVNWCUtil.createDefaultAuthenticationManager(username,pwd);
svnRepository.setAuthenticationManager(authenticationManager);
//===========================前面幾步和打印樹是一樣的END===================================
long startVersion = 10;
long endVersion = 8;
/*
* 參數：
* 1.接收日誌
* 2.接收history對象，每個修訂版的信息都代表一個SVNLogEntry對象。如果我們不需要傳入一個已經存在的history對象，就傳入null值
* 3.開始修訂版本號，0、-1代表最新版本
* 4.結束修訂版本號，0、-1代表最新版本
* 5.如果需要打印改變路徑的信息，則設置為true。會使用每個SVNLogEntry對象記錄改變路徑的信息getchangedpaths()會返回一個Map<String改變路徑,SVNLogEntryPath> 對象
* 6.strictNode設置為true，復制history的時候不會跳過每個path的修訂版日誌
*/
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("序列化數據：" + 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));
}
}
}
}
}
}
}
運行效果：
序列化數據：{"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":"初始化導入目錄-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}}
