Course Introduction:JavaEnterpriseJavaBeans (EJB) is a server-side framework for building scalable and maintainable enterprise applications. Proper deployment and maintenance of EJBs is critical to ensure system stability and performance. EJB deployment EJB deployment involves deploying EJB components (session beans, entity beans, message-driven beans) into a JavaEE application server. Using EJBJAR files: EJB components are packaged in EJBjar files (.ejb-jar). Deploys the EJBJAR file to the application server, enabling it to load and manage EJB components. Configure deployment descriptor: deployment.xml file specifies EJB component

Course Introduction:In Java enterprise development, EJB (EnterpriseJavaBeans) and spring framework are widely used technologies. EJB provides a standardized way to develop distributed applications, while Spring is a lightweight ioc (inversion of control) and aop (aspect-oriented programming) framework for simplifying application development. By integrating EJB and Spring, developers can take full advantage of the two frameworks to improve development efficiency and application performance. Advantages of EJB and Spring Advantages of EJB: Follow standardized EJB specifications to ensure the portability and scalability of applications. Provides enterprise-level functions such as transaction management, security management, and concurrency control.

Course Introduction:The Rise of Cloud Computing The popularity of cloud computing has had a significant impact on EJB technology. EJB servers can now be deployed on cloud platforms such as AWS, Azure and Google Cloud, which provides scalability, reliability and cost-effectiveness. In addition, cloud-native EJB implementations (such as OpenEJB) are optimized for cloud environments, with features such as automatic scaling, failover, and continuous integration. Microservice architecture The rise of microservice architecture has posed new challenges to EJB technology. Traditionally, EJB applications were monolithic, but microservices architecture requires applications to be broken down into smaller independent services. EJB 3.2 introduced stateless beans, which are very useful for deploying EJBs in microservice environments. In addition, the new microservices framework

Course Introduction:EJB and Big Data Analysis JavaEnterpriseJavaBeans (EJB) is a framework widely used to develop distributed enterprise applications. It provides core enterprise capabilities such as transaction processing, concurrency, and security. With the advent of the big data era, EJB has been extended to process and analyze the growing amount of data. By integrating big data technologies, EJB applications can: Process and store massive amounts of data Perform complex data analysis tasks Provide access to real-time data Support data-driven decision making EJB and big data integration example The following code shows how to use EJB to integrate with Apachespark.
