1.JPAJPA (Java Persistence API) is the Java Persistence specification proposed by Sun. It provides Java developers with an object/association mapping tool to manage relational data in Java applications. The main purpose of his presence is to simplify existing persistent development efforts and integrate ORM technology, and to end the current Hibernate,toplink,jdo and other ORM frameworks for each battalion. It is worth noting that JPA is developed on the basis of fully absorbing the existing HIB

What Spring boot is. To simplify the initial setup and development of new spring applications. The framework uses a specific approach to configuration, which eliminates the need for developers to define boilerplate configurations. The goal of Spring boot is not to provide a

CDI (Context Dependency injection) was introduced from Java EE6, and Java EE's design philosophy was very academic, and Gavin King was out of the industry's needs, making Java EE Development very complex.
