Tomcat使用者名稱問題

在tomcat 7 免安裝版本中，使用者名稱和密碼預設都是沒有啟用的，需要我們手動在tomcat-users.xml檔案裡指定（在conf檔案夾下），這個檔案裡面已經寫好了一些帳號的資訊，只是預設的是注釋了而已，取消注釋之後，用這個檔案提供的使用者名稱和密碼去訪問的時候，會出現403錯誤，這是因為我們沒有指定使用者所擁有的許可權的原因、如我們現在想訪問tomcat中的圖形化管理應用的功能，也就是Manager App，我們就需要指定manager-gui的許可權，想訪問host
manager 就必須指定admin-gui許可權等。下面是一個可用的tomcat-users.xml檔案。
