使用SVNKit获取SVN历史记录
一、简介
SVNKit是一个纯Java版本控制(SVN)工具库(library)。
二、下载
在官网下载Standalone版本并解压，将解压后的svnkit-1.10.1\lib下的jar添加到Build Path中。
三、样例
1、打印SVN库历史记录
- 源码
package com.svnkit;
import java.util.Collection;
import java.util.Map;
import java.util.Map.Entry;
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;
public class History {
public static void main(String[] args) {
// http协议对应的SVNRepositoryFactory实现
DAVRepositoryFactory.setup();
String url = "http://acer/svn/myrepository/myproject";
String name = "albert";
char[] password = { 'w', 'z', 'k' };
long startRevision = 0;
long endRevision = -1; // HEAD (the latest) revision
SVNRepository repository = null;
try {
// 创建基于特定协议的SVNRepository驱动程序
repository = SVNRepositoryFactory.create(SVNURL.parseURIEncoded(url));
// 创建身份验证管理器
ISVNAuthenticationManager authManager = SVNWCUtil.createDefaultAuthenticationManager(name, password);
// 设置一个提供用户凭据的身份验证管理器
repository.setAuthenticationManager(authManager);
// 不指定具体路径，获取所有被修改的文件
String[] targetPaths = new String[] { "" };
Collection<SVNLogEntry> logEntries = repository.log(targetPaths, null, startRevision, endRevision, true,
true);
for (SVNLogEntry logEntry : logEntries) {
System.out.println("---------------------------------------------");
System.out.println(String.format("revision: %s", logEntry.getRevision()));
System.out.println(String.format("author: %s", logEntry.getAuthor()));
System.out.println(String.format("date: %s", logEntry.getDate()));
System.out.println(String.format("message: %s", logEntry.getMessage()));
// 修改的文件路径
Map<String, SVNLogEntryPath> changedPaths = logEntry.getChangedPaths();
if (!changedPaths.isEmpty()) {
System.out.println();
System.out.println("changed paths:");
for (Entry<String, SVNLogEntryPath> changedPath : changedPaths.entrySet()) {
SVNLogEntryPath entryPath = changedPath.getValue();
System.out.println(String.format("%s %s %s", entryPath.getType(), entryPath.getKind(),
entryPath.getPath()));
}
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
- 输出

2、统计修改情况
统计修改了指定路径的人员及修改次数：
- 源码
package com.svnkit;
import java.util.HashMap;
import java.util.Map;
import java.util.Map.Entry;
import org.tmatesoft.svn.core.ISVNLogEntryHandler;
import org.tmatesoft.svn.core.SVNException;
import org.tmatesoft.svn.core.SVNLogEntry;
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;
public class AnalysisHistory {
public static void main(String[] args) {
// http协议对应的SVNRepositoryFactory实现
DAVRepositoryFactory.setup();
String url = "http://acer/svn/myrepository/myproject";
String name = "albert";
char[] password = { 'w', 'z', 'k' };
SVNRepository repository = null;
try {
// 创建基于特定协议的SVNRepository驱动程序
repository = SVNRepositoryFactory.create(SVNURL.parseURIEncoded(url));
// 创建身份验证管理器
ISVNAuthenticationManager authManager = SVNWCUtil.createDefaultAuthenticationManager(name, password);
// 设置一个提供用户凭据的身份验证管理器
repository.setAuthenticationManager(authManager);
// 统计指定路径的修改记录
String[] paths = new String[] { "HelloWorld.java", "images/agent-01.png" };
for (String path : paths) {
analysis(repository, path);
}
} catch (Exception e) {
e.printStackTrace();
}
}
private static void analysis(SVNRepository repository, String path) throws SVNException {
long startRevision = 0;
// HEAD (the latest) revision
long endRevision = -1;
// 人员与修改次数的map
Map<String, Integer> countMap = new HashMap<>();
// 不获取changedPath
repository.log(new String[] { path }, startRevision, endRevision, false, true, 10, new ISVNLogEntryHandler() {
@Override
public void handleLogEntry(SVNLogEntry logEntry) throws SVNException {
String author = logEntry.getAuthor();
Integer count = countMap.get(author);
if (count == null) {
count = 0;
}
countMap.put(author, count + 1);
}
});
System.out.println(String.format("The file %s: ", path));
for (Entry<String, Integer> entry : countMap.entrySet()) {
System.out.println(String.format("%s\t%stimes", entry.getKey(), entry.getValue()));
}
System.out.println();
}
}
- 输出
The file HelloWorld.java:
tom 1times
albert 2times
The file images/agent-01.png:
tom 1times
