The Java language is one of the most common back-end development languages, and it has been widely adopted in the development of large Internet platforms because of its ability to build multithreaded and its neutral architecture.
Today, to engage in back-end development for Java, you should learn the following:
First, Servlet technology
Servlet technology is one of the most important technologies in the Java backend, and as a core component of Java Web development, Servlet assumes the central role (functional navigation) of the Web MVC architecture. A lthough the traditional Model2 architecture (Servlet-JavaBean-JSP) is rarely used to this day, the basic structure of Web development remains unchanged. Applications of Servlet technology involve web containers, sessions, security, synchronization, web app deployment, and more.
Second, Java operates the database.
Back-end development inevitably deals with databases, so mastering Java's database operations is a basic requirement. Java operation database involves JDBC, JNDI, RMI, DAO and so on, where the use of RMI-JDBC is a common solution for building java database development, and JNDI is the definition of various resources.
Third, the Spring framework.
Spring-SpringMVC-MyBatis is a more common back-end development scenario, Spring's principle is to build a "business component container," SpringMVC is a specific implementation framework for Web MVC, and MyBatis is a DAO-based implementation framework. F rom a performance perspective, Spring is a lightweight solution for the EJB and is popular with Java programmers. I f you have servlets and the basis for database operations, learning how to use these frameworks is a very easy process. While Spring-based programming is convenient, Spring also has drawbacks, such as overly cumbersome profiles.
Fourth, combine hadoop to build distributed development of Java
Distributed development in Java is an important part of improving Java back-end processing power, and RMI is a common solution for Java distributed development. After learning RMI, you can learn more about building distributed applications for Java on the Hadoop platform (big data platform), and Docker (commonly used in cloud computing) is also a good platform for building distributed development.
Java development involves more content and requires a systematic learning process, which is recommended to be learned in practice, so that the effect is better.
