ClassDemo类

public class ClassDemo extends PropertyPlaceholderConfigurer {

  if (userName != null && password != null && address != null) {
   props.setProperty("jdbc.username", ABC.getInstance_128().decryptStr(userName));----->ABC是用来加密的类
   props.setProperty("jdbc.password", ABC.getInstance_128().decryptStr(password));
   props.setProperty("jdbc.address", address);
  } else {
   logger.info("Lost username|password|address in properties File!!.");
   throw new NotReadablePropertyException(DbPropertyDecrypt.class, "");
  }
  logger.info("Database connection info:  URL: " + address + " Username: " + userName + " Password: " + password);
  super.processProperties(beanFactory, props);
