然后附件中的文件就派上用場了（encrypt2.bat，commons-dbcp-1.2.2.jar和commons-pool-1.4.jar ）

1、進入tomcat的安裝目錄： tomcatroot\common\lib

2、復制encrypt2.bat和commons-dbcp-1.2.2.jar和commons-pool-1.4.jar 進入該目錄

3、進入cmd狀態(tài)，切換入tomcatroot\common\lib目錄 ，非常重要的是需要把webapps下面的各個應用里面的重復的jar刪掉也就是要把所有的字母里面的commons-dbcp*.jar和commons-pool*.jar刪掉

4、輸入encrypt2.bat test （test）還是原密碼，界面上會輸出：

test 加密后： jAVagnSq2eQ=

test 解密后： test

5、修改context.xml password="jAVagnSq2eQ=" 并注意增加一行： factory="org.apache.commons.dbcp.BasicDataSourceFactory"

那么我們最后的配置就是：

<?xml version="1.0" encoding="UTF-8"?>

<!– The contents of this file will be loaded for each web application –>

<context>

<!– Default set of monitored resources 172.16.5.28:KM–>

?????????? maxwait="10000"

?????????? username="test"

?????????? password="jAVagnSq2eQ="

?????????? driverClassName="oracle.jdbc.OracleDriver"

?????????? factory="org.apache.commons.dbcp.BasicDataSourceFactory"??????????????

好了，重啟試試吧
