tomcat JNDI 加密

由于tomcat 未提供数据源加密逻辑，有需要的可以参考以下

   	将解压后得到的tomcatJNDIEncrypt.jar 拷贝至tomcat7主目录/lib 目录中。
    修改至tomcat7主目录/conf/context.xml 中的Resource标签，添加
    	factory="aurora.tomcat.jndi.encrypt.AuroraTomcat7SecurityBasicDataSourceFactory"

tomcat JNDI 加密

写入加密后的密码，重启tomcat。

核心代码如下

package aurora.tomcat.jndi.encrypt;

import java.util.Hashtable;

import javax.naming.Context;
import javax.naming.Name;

import org.apache.tomcat.dbcp.dbcp.BasicDataSource;

import aurora.security.crypto.encrypt.Base64Encryptor;
/**

public class AuroraTomcat7SecurityBasicDataSourceFactory extends org.apache.tomcat.dbcp.dbcp.BasicDataSourceFactory {

	@Override
	public Object getObjectInstance(Object obj, Name name, Context nameCtx, Hashtable environment) throws Exception {
		Object o = super.getObjectInstance(obj, name, nameCtx, environment);
		if (o != null) {
			BasicDataSource ds = (BasicDataSource) o;
			if (ds.getPassword() != null && ds.getPassword().length() > 0) {
				// 密码解密逻辑
				String pwd = new Base64Encryptor().decrypt(ds.getPassword());
				ds.setPassword(pwd);
			}
			return ds;
		} else {
			return null;
		}
	}
