web項目發布到Tomcat之后,如果tomcat是安裝在比如

C:\Program?Files\Apache?Software?Foundation\Tomcat?6.0\webapps\****

那么你獲取當前類的路徑的時候,就會出現問題,因為它會報出%20

C:\Program%20Files\Apache%20Software%20Foundation\Tomcat?6.0\webapps\****

這個時候你再做一些關于文件的操作,程序就掛了,報一些未知錯誤,那么解決方案就是使用字符串的replace方法,進行字符串替換即可.

?

//獲取當前類加載器,并找到指定目錄POOLCONFIG_FOLDER是之前設置好的static?變量

String?path?=?Thread.currentThread().getContextClassLoader().getResource(POOLCONFIG_FOLDER).getPath();

//進行字符串替換

path?=?path.replace("%20",?"?");

public?class?DBUtil{?????????private?static?String?POOLCONFIG_FOLDER?=?"pools";?????????private?static?void?init()????{????????/**?????????*?方法一,利用當前類加載器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,利用當前類加載器2?????????*/????????//String?path?=?DBUtil.class.getClassLoader().getResource(POOLCONFIG_FOLDER).getPath();????????//path?=?path.replace("%20",?"?");????????//?File?folder?=?new?File(path);??????????????????????????/**?????????*?方法三,利用當前線程類加載器?????????*/????????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("加載DBUtil出現問題。。。。。");????????????????????logger.error(e.getMessage());????????????????}????????????}????????}????}}

Tomcat下獲取當前類的路徑中含有空格的解決方案
