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; }
