The structure of the XML file is generally as followsxmlns is an abbreviation for XML Namespace, which represents the spring namespace. Spring finds all the spring.handlers in Classpath and parses the XML

, Spring will automatically instantiate property B if it finds that property B is not instantiated when obtaining property, this is also an important feature provided by Spring. In some cases, B will not be initialized, such as implementing the BeanNameAware interface. This is introduced in Spring: the specified dependency interfaces are ignored during Automatic

We all know that Java reads ordinary files through basic I/O InputStream, OutStream, Reader, Writer and so on. In the spring framework, how does it identify the XML configuration file?This depends on the two interfaces of the IOC container beanfactory and applicationcontext: beanfactory Interface |--------

OverviewIt is well known that the Spring framework is a driver of the control inversion (IOC) or Dependency injection (DI) pattern, which is implemented through container-based configuration. In the past, Spring allowed developers to use XML-based configuration to manage
