 <bean id="datasource"

  <property name="username" value="xxxx" />
  <property name="password" value="xxxx" />

</beans>

 

就用:

 

 

BaseDAO userDAO = null;
  try {

    userDAO = (BaseDAO) xxx.getBeanFactory().getBean("userDAO");
  } catch (Exception e) {
   e.printStackTrace();
  }

  // find all
  List list = userDAO.findAll();
  System.out.println("user count: " + list.size()
    + ((UserVO) list.get(0)).getName());
