What is Pojo?

According to Martin Fowler's explanation is "Plain old Java object", literally translated as "pure older Java objects", but everyone uses "simple Java object" to call it. The intrinsic meaning of Pojo refers to Java objects that do not inherit from any class, do not implement any interfaces, and are not invaded by other frameworks.

Comparison of Pojo and JavaBean
The Pojo format is used for temporary transfer of data, which can only load data as a carrier of data storage, without the ability to handle business logic.
JavaBean Although the data acquisition and Pojo the same, but JavaBean can have other methods.

JavaBean is a reusable component written in the Java language. Its method naming, construction and behavior must conform to a specific convention:
This class must have a public default constructor.
The properties of this class are accessed using getter and setter, and other methods conform to standard naming conventions.
This class should be serializable.
