hibernate的cfg.xml配置檔案使用者名稱密碼是明文存放，配置檔案裡的引數資訊解析都是通過provider_class負責。定義一個子類繼承provider_class連線供應類。

1、這裡我用的是c3p0的連線供應類，故要繼承C3P0ConnectionProvider

package utils;

import java.util.Map;

import org.hibernate.HibernateException;
import org.hibernate.c3p0.internal.C3P0ConnectionProvider;
import org.hibernate.cfg.Environment;

public class CustomDriverManagerConnectionProvider extends C3P0ConnectionProvider {
	
	public CustomDriverManagerConnectionProvider() {
		super();
	}
	/*
	* (non-Javadoc)
	* 
	* @see org.hibernate.connection.DriverManagerConnectionProvider#configure(java.util.Properties)
	*/
	@Override
	public void configure(Map props) throws HibernateException {
		String user = (String)props.get(Environment.USER);
		String password = (String)props.get(Environment.PASS);
		if(ToolUtils.stringIsNull(user)){
			 throw new HibernateException("資料庫帳號不能為空！");
		}
		if(ToolUtils.stringIsNull(password)){
			 throw new HibernateException("資料庫密碼不能為空！");
		}
		//解密
		AESUtils aes = new AESUtils();
		props.put(Environment.USER, aes.decode(user));
		props.put(Environment.PASS, aes.decode(password));
		super.configure(props);
	}
}
 

2、把自定義的連線提供類配置到hibernate.cfg.xml

<property name="hibernate.connection.provider_class">utils.CustomDriverManagerConnectionProvider</property>
