𝘼𝙙𝙫𝙖𝙣𝙩𝙖𝙜𝙚𝙨 𝙤𝙛 𝙎𝙥𝙧𝙞𝙣𝙜 𝙁𝙧𝙖𝙢𝙚𝙬𝙤𝙧𝙠 There are many advantages to the Spring Framework. 𝟭) 𝗣𝗿𝗲𝗱𝗲𝗳𝗶𝗻𝗲𝗱 𝗧𝗲𝗺𝗽𝗹𝗮𝘁𝗲𝘀 Spring framework provides templates for JDBC, Hibernate, JPA, etc. technologies. So there is no need to write too much code. It hides the basic steps of these technologies. Let's take the example of JdbcTemplate, you don't need to write the code for exception handling, creating connection, creating a statement, committing the transaction, closing connection, etc. You need to write the code of executing queries only. Thus, it saves a lot of JDBC code. 𝟮) 𝗟𝗼𝗼𝘀𝗲 𝗖𝗼𝘂𝗽𝗹𝗶𝗻𝗴 The Spring applications are loosely coupled because of dependency injection. 𝟯) 𝗘𝗮𝘀𝘆 𝘁𝗼 𝘁𝗲𝘀𝘁 The Dependency Injection makes easier to test the application. The EJB or Struts application requires the server to run the application but the Spring framework doesn't require a server. 𝟰) 𝗟𝗶𝗴𝗵𝘁𝘄𝗲𝗶𝗴𝗵𝘁 Spring framework is lightweight because of its POJO implementation. The Spring Framework doesn't force the programmer to inherit any class or implement any interface. That is why it is said non-invasive. 𝟱) 𝗙𝗮𝘀𝘁 𝗗𝗲𝘃𝗲𝗹𝗼𝗽𝗺𝗲𝗻𝘁 The Dependency Injection feature of Spring Framework and its support to various frameworks make the easy development of the JavaEE application. 𝟲) 𝗣𝗼𝘄𝗲𝗿𝗳𝘂𝗹 𝗮𝗯𝘀𝘁𝗿𝗮𝗰𝘁𝗶𝗼𝗻 It provides a powerful abstraction to JavaEE specifications such as JMS, JDBC, JPA, and JTA. 𝟳) 𝗗𝗲𝗰𝗹𝗮𝗿𝗮𝘁𝗶𝘃𝗲 𝘀𝘂𝗽𝗽𝗼𝗿𝘁 It provides declarative support for caching, validation, transactions, and formatting.

What is BeanFactory in Spring?

A BeanFactory is like a factory class that contains a collection of beans. The BeanFactory holds Bean Definitions of multiple beans within itself and then instantiates the bean whenever asked for by clients. The BeanFactory is the actual container that instantiates, configures, and manages a number of beans. These beans typically collaborate with one another and thus have dependencies between themselves. These dependencies are reflected in the configuration data used by the BeanFactory BeanFactory also takes part in the life cycle of a bean, making calls to custom initialization and destruction methods.
