B/S实现远程配置SVN2008-12-26 作者：dyerac 来源：最近在尝试做一个类似sourceforge的开源社区，因此需要为项目申请者提供远程SVN的配置。这里列出自己的代码和心得，一是为了与大家相互交流，更重要的是为了让各位提提意见，看看还需要什么内容。现在提供的功能有：为项目创建svn仓库，修改svn账户密码，修改svn权限配置等。大家觉得还需要什么呢？代码如下：首先定义一个异常：package commandLineTest;class SvnException extends Exception public SvnException(String s) super(s);下面是对svn的操作： package commandLineTest;import java.io.BufferedReader;import java.io.BufferedWriter;import java.io.File;import java.io.FileNotFoundException;import java.io.FileReader;import java.io.FileWriter;import java.io.IOException;import java.io.InputStreamReader;public class SvnCommander private String svn_home = K:/subversion-repository/;/* */* 为指定项目在服务器创建svn仓库,当用户选择开通svn服务时,这个方法将被调用为用户的项目创建svn仓库* * param project* 需要创建svn仓库的项目的名称* throws SvnException* 当创建失败时将抛出错误*/public void createRepository(String project) throws SvnException try Process p = new ProcessBuilder(svnadmin, create, svn_home+ project).start();StringBuffer buffer = new StringBuffer();String tmp;/ BufferedReader reader=new BufferedReader(new/ InputStreamReader(p.getInputStream();/ while(tmp=reader.readLine()!=null)/ buffer.append(tmp);/ System.out.println(buffer.toString();/ buffer=new StringBuffer();BufferedReader reader = new BufferedReader(new InputStreamReader(p.getErrorStream();while (tmp = reader.readLine() != null)buffer.append(tmp);/ System.err.println(buffer.toString();if (buffer.length() 0)throw new SvnException(buffer.toString();initSvnServer(project);initAuthz(project);
