#hibernate2

最近公司做配置文件加密项目，遇到一个应用使用的是Hibernate2，在网上没有找到现有的Hibernate2的方案，于是自己参考jasypt的源码，写了一个Connection Provider实现了加密运作

其中Encoded.decrypt加密、解密的类在此不提供，各位自己发挥

import java.util.Properties;

import com.walmart.init.Encoded;

import net.sf.hibernate.HibernateException; import net.sf.hibernate.connection.DriverManagerConnectionProvider;

public final class EncryptedPasswordDriverManagerConnectionProvider extends DriverManagerConnectionProvider {

public void configure(Properties props) { String user = props.getProperty("hibernate.connection.username"); String password = props.getProperty("hibernate.connection.password"); if (isEncryptedValue(user)) { user = getInnerEncryptedValue(user); props.setProperty("hibernate.connection.username", Encoded.decrypt(user)); } if (isEncryptedValue(password)) { password = getInnerEncryptedValue(password); props.setProperty("hibernate.connection.password", Encoded.decrypt(password)); } try { super.configure(props); } catch (HibernateException e) { // TODO Auto-generated catch block e.printStackTrace(); } } public static boolean isEncryptedValue(String value) { if (value == null) { return false; } String trimmedValue = value.trim(); return (trimmedValue.startsWith("ENC(")) && (trimmedValue.endsWith(")")); } private static String getInnerEncryptedValue(String value) { return value.substring("ENC(".length(), value.length() - ")".length()); }

}

Hibernate.cfg.xml文件供参考
