In-depth analysis of common Spring-boot-starter dependency modules, Two major advantages of Spring-boot: 1. The "conventions over configuration (COC)" concept based on the Spring framework and the path to best practices. 2. automatically configure the dependency module for Spring-boot-starter in various daily enterprise application R D scenarios, and "out-of-the-box" (the spring-boot-starter-is specified as the naming prefix, all of which are located

, including dependencies between models.6. Session parameters, such as loginUserId, are also injected to the Controller through setter. If a request parameter is injected with loginUserId, it will also be overwritten by the Session parameter.7. One-to-one View and Controller are mapped by name and support various View template types, such as JSP, Velocity, FreeMarker, and CommonTemplate.8. View execution can be performed without a Controller, which is equivalent to implicit Controller.9. the fra

. Controller uses getter feed data to view, in view can be directly taken to the corresponding property values, such as: ${property}.3. The controller handles the request with any non-setter and getter functions.4. Controller takes the function return value to control the jump, only allows to jump to another controller, does not allow a controller to correspond to two view.5. The controller's reliance on the model is automatically assembled by the setter, including the dependence between the mod
