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; charset=utf-8"

    pageEncoding="utf-8"%>

    <%

    String path = request.getContextPath();

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

           + request.getServerName() + ":" + request.getServerPort()

           + path + "/";

    %>
