Spring entry (5) [springMVC environment setup], springspringmvc SpringMVC, as a WEB component of spring, is a MVC idea that reduces the difficulty of WEB development. The establishment of springMVC environment is introduced. The specific principles are described later. Anyone who has used the framework knows that to use a framework in a WEB project, this framewor

Portlet context. This scope is only really valid if you are using spring in a web app.More commonly used are singleton and prototype two scopes, and for singleton scoped beans, each request for the bean will get the same instance. The container is responsible for keeping track of the state of the bean instance and is responsible for maintaining the life cycle behavior of the bean instance; If a bean is set to prototype scope, the program will create

implement the Beanfactorypostprocessor interface? The purpose of implementing the Beanfactorypostprocessor interface is to make the Bean's load time advance, higher than the target bean's initialization. Otherwise, the timeout attribute in the target Bean is injected to the end, and the subsequent operation is meaningless.SummarizePlainly, just don't want to write configuration file!!!And do not want to change the code of the old project, the old project even in the case of deleting the configu

(that is, Filesystemapplicationcontext is not the real resourceloader) treats absolute paths and relative paths as normal conditions. The relative path is relative to the current working directory, and the absolute path is relative to the root of the file system.However, for a forward compatible (historical) reason, when Filesystemapplicationcontext is Resourceloader, it is not the same. FilesystemapplicationcontextForces all of the Filesystemresource instances it loads to treat all paths as re

Programming As we all know, spring is a proponent of interfacing programming. But there are some service categories, such as Saleordermanager and Saleordermanagerimpl, with only 5% chance of another IMPL implementation. 95% time the two brothers stand together, just like C + +. H and. cpp, increased maintenance of the cumbersome, so just start with spring when yo

and enhancementThe introduction enhancement is a kind of special enhancement type, it does not weave the enhancement around the target method, but creates new methods and properties for the target class, so the connection point of the interface enhancement is class-level, not method-level. With the introduction enhancement, we can add an interface implementation for the target class, that is, the original target class does not implement an interface, through the introduction of the enhancement
