BeanFactory allows inputStream as a parameter of the constructor, or ORG.SPRINGFRAMEWORK.CORE.IO.Resource interface. Below this example is the parameters with ClassPathResource as a parameter:
Resource resource = new classpathResource ("bean.xml"); beanfactory factory = new xmlbeanfactory; actionBean action = (ActionBean) Factory.getBean ("ActionBean");
If the same bean has multiple beans definitions in the configuration file, all objects are obtained with the following method:
Resource resource = new classpathResource ("bean.xml"); listablebeanfactory factory = new xmlbeanfactory; map hellobeans = factory.getBeansoftype (ActionBean.class, false, false);
There are often many beans in an app to be placed in the configuration file. If all beans are placed in a file, it is quite troubles to maintain it. At this time, we can use each module to put each module to becomes different. Profile, Spring provides a corresponding method:
BeanDefinitionRegistry reg = new DefaultListableBeanFactory (); XmlBeanDefinitionReader reader = new XmlBeanDefinitionReader (reg); // Loading bean definition file reader.loadBeanDefinitions (new ClassPathResource ( "bean1.xml")); reader.loadBeanDefinitions (new ClassPathResource ( "bean2.xml ")); .... // Get beanbeanfactory bf = (beanfactory) reg; object o = bf.getBean (" ActionBean ");
