Java 调用svnkit实现svn功能

· 显示版本树



把svnkit.jar添加到项目中，用于实现svn功能。 把jackson-all-1.6.2.jar添加到项目中，用于显示树列表。把javaee.ar添加到项目中。

新建一个类(SVNUtil.class)实现svn功能
private String svnRoot;
private String userName;
private String password;
private SVNRepository repository;

/***
* 构造方法
* @param svnRoot
* svn根目录
*/
public SVNUtil(String svnRoot) {
this.svnRoot=svnRoot;
}
/***
* 构造方法
* @param svnRoot
* svn根目录
* @param userName
* 登录用户名
* @param password
* 登录密码
*/
public SVNUtil(String svnRoot, String userName, String password) {
this.svnRoot=svnRoot;
this.userName=userName;
this.password=password;
}
/***
* 通过不同的协议初始化版本库
*/
private static void setupLibrary()
{
// 对于使用http://和https：//
DAVRepositoryFactory.setup();
//对于使用svn：/
/和svn+xxx：/ /
SVNRepositoryFactoryImpl.setup();
//对于使用file://
FSRepositoryFactory.setup();
}
每次连接库都进行登陆验证
/***
* 登录验证
* @return
*/
public boolean login(){
setupLibrary();
try{
//创建库连接
repository=SVNRepositoryFactory.create(SVNURL.parseURIEncoded(this.svnRoot));
//身份验证
ISVNAuthenticationManager authManager = SVNWCUtil
.createDefaultAuthenticationManager(this.userName,
this.password);
//创建身份验证管理器
repository.setAuthenticationManager(authManager);
return true;
} catch(SVNException svne){
svne.printStackTrace();
return false;
}
}
下面的方法实现查询给定路径下的条目列表功能
/***
*
* @param path
* @return 查询给定路径下的条目列表
* @throws SVNException
*/
@SuppressWarnings("rawtypes")
public List<SVN> listEntries(String path)
throws SVNException {
Collection entries = repository.getDir(path, -1, null,
(Collection) null);
Iterator iterator = entries.iterator();
List<SVN> svns = new ArrayList<SVN>();
while (iterator.hasNext()) {
SVNDirEntry entry = (SVNDirEntry) iterator.next();
SVN svn = new SVN();
svn.setCommitMessage(entry.getCommitMessage());
svn.setDate(entry.getDate());
svn.setKind(entry.getKind().toString());
svn.setName(entry.getName());
svn.setRepositoryRoot(entry.getRepositoryRoot().toString());
svn.setRevision(entry.getRevision());
svn.setSize(entry.getSize()/1024);
svn.setUrl(path.equals("") ? "/"+entry.getName() : path
+"/"+entry.getName());
svn.setAuthor(entry.getAuthor());
svn.setState(svn.getKind() == "file"?null:"closed");
svns.add(svn);
}
新建一个SVNServlet
添加一个方法用于把java对象转换为json字符串
/**
* 将java对象转换为json字符串
*
* @param obj
* :可以为map,list,javaBean等
* @return json字符串
* @createTime 2010-11-23 下午07:42:58
*/
public static String object2Json(Object
obj) {
try {
StringWriter sw = new StringWriter();
JsonGenerator gen = new JsonFactory().createJsonGenerator(sw);
mapper.writeValue(gen, obj);
gen.close();
return sw.toString();
} catch (Exception e) {
e.printStackTrace();
}
return null;
}

protected void doGet(HttpServletRequest
request,
HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
this.doPost(request, response);
}

protected void doPost(HttpServletRequest
request,
HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
Object svns = null;
request.setCharacterEncoding("UTF-8");
response.setCharacterEncoding("UTF-8");
String path = request.getParameter("pid");
String url = "svn://localhost/svndemo1";
String usrName = "usrName";
String password = "password";
if (path == null) {
path = "";
}
path = new String(path.getBytes("ISO-8859-1"),"UTF-8");
String type = request.getParameter("type");
PrintWriter out = response.getWriter();
try {
SVNUtil svnUtil = new SVNUtil(url, usrName, password);
if (svnUtil.login()) {
/*用于查询历史记录
if ("history".equals(type)) {
List<SVN> svnl = svnUtil.getHistory(path);
HashMap<String, Object> sv = new HashMap<String, Object>();
sv.put("total", svnl.size());
sv.put("rows", svnl);
svns = sv;
} else {*/
svns = svnUtil.listEntries(path);
//}
//把java对象转换成json字符串
String json = SVNServlet.object2Json(svns);
out.print(json);
} else {
System.out.println("验证失败");
}
} catch (SVNException ex) {
ex.printStackTrace();
}
out.flush();
out.close();
}
新建一个index.jsp用户显示版本数列表，页面显示我使用了jquery-easyui模板
<%@ page language="java" contentType="text/html;

pageEncoding="utf-8"%>

String path = request.getContextPath();
String basePath = request.getScheme() + "://"
+ request.getServerName() + ":" + request.getServerPort()
