Jboss 数据源密码明文加密

转载:https://blog.csdn.net/iberr/article/details/40896479

备注:解密小程序没有测试,知识了解了加密解密过程。对自己的帮助是看懂了连接数据库的配置,然后可以修改。

这边的Jboss版本为 5.1.0.

下面来看一看.

默认数据源配置如下:

<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>
用户名密码都是明文.


我们可以进行小小的更改,编辑它:

<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>
编辑后,变成如上所示,那么这个安全域配置在哪里呢,往下看


编辑 JBOSS_HOME/server/Default/Conf/login-config.xml,添加一个节点:

<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 对应,一定要一致.
username:数据库用户名

password:加密后的密码

managedConnectionFactoryName:name={Datasource 中的JndiName},这点也很重要

其实上面都挺简单的.

下面重点来了,密码加密命令(其实就是加载Jboss的一个jar文件,调用Java类生成输出)

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 $password$
执行就行了,控制台会输出密码的.

重点又来了,数据源太多,一个个改费劲,上一小段代码.

}

output(newName,jndiName,userName,password);

}



}

}

}

return String.format(tpl, newName);

}

Jboss这个SecureIdentityLoginModule类是做加密解密的,但是他的加密方法是私有的,我这个包不能访问

}

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

c2e.startConvert("D:\\work\\workspace\\RESOURCE\\tools\\source\\scewebserver-ds.xml");



}
}

到此结束.
