web项目发布到Tomcat之后,如果tomcat是安装在比如
C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps\****
那么你获取当前类的路径的时候,就会出现问题,因为它会报出%20
C:\Program%20Files\Apache%20Software%20Foundation\Tomcat 6.0\webapps\****
这个时候你再做一些关于文件的操作,程序就挂了,报一些未知错误,那么解决方案就是使用字符串的replace方法,进行字符串替换即可.
//获取当前类加载器,并找到指定目录POOLCONFIG_FOLDER是之前设置好的static 变量
String path = Thread.currentThread().getContextClassLoader().getResource(POOLCONFIG_FOLDER).getPath();
//进行字符串替换
path = path.replace("%20", " ");
public class DBUtil{ private static String POOLCONFIG_FOLDER = "pools"; private static void init() { /** * 方法一,利用当前类加载器1 */ // URL url = Thread.currentThread().getContextClassLoader().getResource(POOLCONFIG_FOLDER); // String path = url.getFile(); // path = path.replace("%20", " "); // File folder = new File(path); /** * 方法二,利用当前类加载器2 */ //String path = DBUtil.class.getClassLoader().getResource(POOLCONFIG_FOLDER).getPath(); //path = path.replace("%20", " "); // File folder = new File(path); /** * 方法三,利用当前线程类加载器 */ String path = Thread.currentThread().getContextClassLoader().getResource(POOLCONFIG_FOLDER).getPath(); path = path.replace("%20", " "); File folder = new File(path); logger.debug("path :" + path); if (folder.isDirectory()) { File[]fileList = folder.listFiles(); for (int i = 0, len = fileList.length; i < len; i++) { try { File file = fileList[i]; String name = file.getName(); name = name.substring(0, name.lastIndexOf(".")); InputStream input = new FileInputStream(file); Properties props = new Properties(); props.load(input); loadPoolConfig(name, props); } catch (Exception e) { e.printStackTrace(); logger.info("加载DBUtil出现问题。。。。。"); logger.error(e.getMessage()); } } } }}
