Tomcat下獲取當前類的路徑中含有空格的解決方案
阿新 • • 發佈：2019-01-31
web專案釋出到Tomcat之後,如果tomcat是安裝在比如
C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps\****
那麼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於檔案的操作,程式就掛了,報一些未知錯誤,那麼解決方案就是使用字串的replace方法,進行字串替換即可.
//獲取當前類載入器,並找到指定目錄POOLCONFIG_FOLDER是之前設定好的static 變數
String path = Thread.currentThread().getContextClassLoader().getResource(POOLCONFIG_FOLDER).getPath();
//進行字串替換
path = path.replace("%20", " ");
