Jboss 數據源密碼明文加密
轉載:https://blog.csdn.net/iberr/article/details/40896479
備註:解密小程序沒有測試,知識了解了加密解密過程。對自己的幫助是看懂了連接數據庫的配置,然後可以修改。
這邊的Jboss版本為 5.1.0.
下面來看一看.
默認數據源配置如下:
<local-tx-datasource>
<jndi-name>jdbc/ADMIN</jndi-name>
<connection-url>jdbc:oracle:thin:@sce10:1521:XXXX</connection-url>
<driver-class>oracle.jdbc.OracleDriver</driver-class>
<user-name>XXXX</user-name>
<password>XXXX</password>
<min-pool-size>0</min-pool-size>
<max-pool-size>100</max-pool-size>
<new-connection-sql>ALTER SESSION SET NLS_DATE_FORMAT = ‘yyyy/mm/dd hh24:mi:ss‘</new-connection-sql>
</local-tx-datasource>
用戶名密碼都是明文.
我們可以進行小小的更改,編輯它:
<local-tx-datasource>
<jndi-name>jdbc/ADMIN</jndi-name>
<connection-url>jdbc:oracle:thin:@sce10:1521:XXXX</connection-url>
<driver-class>oracle.jdbc.OracleDriver</driver-class>
<min-pool-size>0</min-pool-size>
<max-pool-size>100</max-pool-size>
<new-connection-sql>ALTER SESSION SET NLS_DATE_FORMAT = ‘yyyy/mm/dd hh24:mi:ss‘</new-connection-sql>
<security-domain>SCPRD_Encrypt_ADMIN_Password</security-domain>
</local-tx-datasource>
編輯後,變成如上所示,那麽這個安全域配置在哪裏呢,往下看
編輯 JBOSS_HOME/server/Default/Conf/login-config.xml,添加一個節點:
<application-policy name="SCPRD_Encrypt_SCPRD_WMWHSE1_Password">
<authentication>
<login-module code="org.jboss.resource.security.SecureIdentityLoginModule" flag="required">
<module-option name="username">wmwhse1</module-option>
<module-option name="password">-7777fac1e4b05d45207a6df87216de44</module-option>
<module-option name="managedConnectionFactoryName">jboss.jca:service=LocalTxCM,name=jdbc/ADMIN</module-option>
</login-module>
</authentication>
</application-policy>
name: DataSource中 security-domain 對應,一定要一致.
username:數據庫用戶名
password:加密後的密碼
managedConnectionFactoryName:name={Datasource 中的JndiName},這點也很重要
其實上面都挺簡單的.
下面重點來了,密碼加密命令(其實就是加載Jboss的一個jar文件,調用Java類生成輸出)
java -cp "C:\Infor\sce\jboss-5.1.0.GA\lib\jboss-logging-spi.jar;C:\Infor\sce\jboss-5.1.0.GA\lib\jboss-jmx.jar;C:\Infor\sce\jboss-5.1.0.GA\lib\jboss-common-core.jar;C:\Infor\sce\jboss-5.1.0.GA\common\lib\jboss-jca.jar;C:\Infor\sce\jboss-5.1.0.GA\common\lib\jbosssx.jar" org.jboss.resource.security.SecureIdentityLoginModule $password$
執行就行了,控制臺會輸出密碼的.
重點又來了,數據源太多,一個個改費勁,上一小段代碼.

這裏大家會覺得很奇怪,為什麽要用反射,下面解答一下
Jboss這個SecureIdentityLoginModule類是做加密解密的,但是他的加密方法是私有的,我這個包不能訪問
你可能會問調用main方法也可以呀,回答是NO,main方法是在控制臺輸出,不是返回一個變量
那麽問題來了,怎麽辦? 反射就可很簡單的解決了,下面代碼就是
* */
Class clz = org.jboss.resource.security.SecureIdentityLoginModule.class;

public static void main(String[] args) throws Exception {

到此結束.
