Java 调用svnkit实现svn功能
·显示版本树
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;
}

HttpServletResponse response)throwsServletException, IOException {

}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

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