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

privateStringsvnRoot;

privateStringuserName;

privateStringpassword;

privateSVNRepositoryrepository;

/***

*构造方法

*@paramsvnRoot

*svn根目录

*/

publicSVNUtil(String svnRoot) {

this.svnRoot=svnRoot;

}

/***

*构造方法

*@paramsvnRoot

*svn根目录

*@paramuserName

*登录用户名

*@parampassword

*登录密码

*/

publicSVNUtil(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

*/

privatestaticvoidsetupLibrary() {

//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

*/

publicbooleanlogin(){

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);

returntrue;

}catch(SVNException svne){

svne.printStackTrace();

returnfalse;

}

}

下面的方法实现查询给定路径下的条目列表功能

/***

*

*@parampath

*@return查询给定路径下的条目列表

*@throwsSVNException

*/

@SuppressWarnings("rawtypes")

publicList<SVN> listEntries(String path)

throwsSVNException {

Collection entries =repository.getDir(path, -1,null,

(Collection)null);

Iterator iterator = entries.iterator();

List<SVN> svns =newArrayList<SVN>();

while(iterator.hasNext()) {

SVNDirEntry entry = (SVNDirEntry) iterator.next();

SVN svn =newSVN();

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

*

*@paramobj

*:可以为map,list,javaBean等

*@returnjson字符串

*@createTime2010-11-23下午07:42:58

*/

publicstaticString object2Json(Object obj) {

try{

StringWriter sw =newStringWriter();

JsonGenerator gen =newJsonFactory().createJsonGenerator(sw);

mapper.writeValue(gen, obj);

gen.close();

returnsw.toString();

}catch(Exception e) {

e.printStackTrace();

}

returnnull;

}

protectedvoiddoGet(HttpServletRequest request,

HttpServletResponse response)throwsServletException, IOException {

//TODOAuto-generated method stub

this.doPost(request, response);

}

protectedvoiddoPost(HttpServletRequest request,

HttpServletResponse response)throwsServletException, IOException {

//TODOAuto-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 =newString(path.getBytes("ISO-8859-1"),"UTF-8");

String type = request.getParameter("type");

PrintWriter out = response.getWriter();

try{

SVNUtil svnUtil =newSVNUtil(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 =newHashMap<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

<%@pagelanguage="java"contentType="text/html; charset=utf-8"

pageEncoding="utf-8"%>

String path = request.getContextPath();

String basePath = request.getScheme() +"://"

%>
