Introduction to Spring MVCSpring MVC is a lightweight web framework based on the MVC architecture pattern that is designed to modularize web development and decouple the overall architecture.Spring MVC has some advantages:As part of the spring framework, it has the advantages of spring (IOC,AOP, etc.)Supports flexible URL-to-page-controller mappingProvides flexible data validation, formatting, and data-binding mechanismsSupport RESTful styleSpring MVC Request ProcessThe overall request flow for

implementations using the framework:Dispatcherservlet: As the front controller, the entire Process Control center, control other components execution, unified scheduling, reduce the coupling between components, improve the extensibility of each component.Handlermapping: Through the extension of the processor mapper to achieve different mapping methods, such as: Configuration file mode, the implementation of interface mode, annotation method and so on.Handladapter: Supports more types of process

Computer networks are often connected by a number of different types of network interconnections. If several computer networks are physically connected and cannot communicate with each other, then this "interconnection" has little practical meaning. As a result, when it comes to "interconnection", it has been suggested that these interconnected computers are capable of communicating, that is to say, functionally and logically, these computer networks have already formed a large computer network,

"interconnection", it has been suggested that these interconnected computers are capable of communicating, that is to say, functionally and logically, these computer networks have already formed a large computer network, or Internet, or, for the short term, a network, an interconnection. Connecting networks to each other uses intermediate devices (or intermediate systems), and ISO terminology is called a relay (relay) system. Depending on the level of the relay system, you can have the followi

, and the plane crashed in the depth of the sea, conditions are very harsh. 　　Many people think that the investigation team will never find a plane, and the same is true of MH370. There are too few clues to the difference. Air France even looking at the wreckage for 2 years in the ocean eyeing like "finding needles in the haystack." At the moment, it seems that rescuers are most in need of clues to "finding needles". From the case of Air France, AF447 has a lot of clues about the location of the
