External Dependencies. This template is used to capture external dependencies, which are tasks, events, or deliverables that are outside of the Project Manager's control (performed by someone not on the project team) that must happen before the project can progress.
What is upstream and downstream in software?
Open Source developers who are "downstream" build applications and tools on the finished products. Those who are upstream actually work on the products to be released. If you develop software: you depend on the stability of the upstream development. And those who work on your software are downstream developers.
In software engineering, dependency injection is a technique whereby one object (or static method) supplies the dependencies of another object. A dependency is an object that can be used (a service). An injection is the passing of a dependency to a dependent object (a client) that would use it.
autodetect. Spring first tries to wire using autowire by constructor, if it does not work, Spring tries to autowire by byType. You can use byType or constructor autowiring mode to wire arrays and other typed-collections.
Marks a constructor, field, setter method or config method as to be autowired by Spring's dependency injection facilities. Only one constructor (at max) of any given bean class may carry this annotation, indicating the constructor to autowire when used as a Spring bean. Such a constructor does not have to be public.
Front controller is a typical design pattern in the web applications development. In this case, a single servlet receives all requests and transfers them to to all other components of the application. The task of the DispatcherServlet is to send request to the specific Spring MVC controller.
A Java servlet is a Java program that extends the capabilities of a server. Although servlets can respond to any types of requests, they most commonly implement applications hosted on Web servers.
HandlerMapping is an interface that defines a mapping between requests and handler objects. While Spring MVC framework provides some ready-made implementations, the interface can be implemented by developers to provide customized mapping strategy.
Spring Interceptor are used to intercept client requests and process them. Sometimes we want to intercept the HTTP Request and do some processing before handing it over to the controller handler methods. That's where Spring MVC Interceptor come handy. 1 Spring Interceptor.
@RequestMapping is one of the most widely used Spring MVC annotation. org.springframework.web.bind.annotation.RequestMapping annotation is used to map web requests onto specific handler classes and/or handler methods. @RequestMapping can be applied to the controller class as well as methods.
@Controller is used to mark classes as Spring MVC Controller. @RestController is a convenience annotation that does nothing more than adding the @Controller and @ResponseBody annotations (see: Javadoc)
@Controller annotation is an annotation used in Spring MVC framework (the component of Spring Framework used to implement Web Application). These classes (or its methods) are typically annotated also with @RequestMapping annotation that specify what HTTP Request is handled by the controller and by its method.
Representational State Transfer (REST) is an architectural style that specifies constraints, such as the uniform interface, that if applied to a web service induce desirable properties, such as performance, scalability, and modifiability, that enable services to work best on the Web.
Spring MVC Framework and REST. Spring's annotation based MVC framework simplifies the process of creating RESTful web services. The key difference between a traditional Spring MVC controller and the RESTful web service controller is the way the HTTP response body is created.
Web services are of two kinds: Simple Object Access Protocol (SOAP) and Representational State Transfer (REST). SOAP defines a standard communication protocol (set of rules) specification for XML-based message exchange. SOAP uses different transport protocols, such as HTTP and SMTP.
A RESTful API -- also referred to as a RESTful web service -- is based on representational state transfer (REST) technology, an architectural style and approach to communications often used in web services development.
Advertisements. As per the REST architecture, a RESTful Web Service should not keep a client state on the server. This restriction is called Statelessness. It is the responsibility of the client to pass its context to the server and then the server can store this context to process the client's further request.
Simple Object Access Protocol (SOAP) and Representational State Transfer (REST) are two answers to the same question: how to access Web services. The choice initially may seem easy, but at times it can be surprisingly difficult. REST as an architecture style does not require processing and is naturally more flexible.
The acronym REST stands for Representational State Transfer, this basically means that each unique URL is a representation of some object.
