The most important core concept is the IOC, and provides an approach to implementing the AOP concept, providing support for persistent layers, transactions, and some of the current popular frameworks (STRUTS,HIBERNATE,MVC), Sping also offers a solution that integrates with them. With spring, we can reduce the dependency bet

4. What about your understanding of the JVM?A: a very important feature of the Java language is its independence from the platform . The use of Java virtual machines is the key to achieving this feature. The Java compiler generates code or bytecode files that the JVM can understand as long as it is oriented to the JVM. The Java source file is compiled into a bytecode program that translates each instruction into a different platform machine code through the JVM, running through a specific platfo

in Web. xml), the Web container will forward the request to dispatcherservlet processing. dispatcherservlet receives the request based on the requested information (including URL, HTTP method, request header, request parameters, cookie, etc.) And the handlermapping configuration to find the processor that processed the request (Handler). Handlermapping can be regarded as a routing controller, handler as the target host. when Dispatcherservlet according to handlermapping g

glance.Compared to EJB containers, IOC containers tend to be more lightweight. This makes it very advantageous for the IOC container to develop and publish applications in the context of limited memory and CPU resources.Spring is not behind closed doors, and spring leverages existing technologies such as ORM Framework, logging framework, Java EE, quartz and jdk Timer, and other view technologies.The spring
