![]() Really helpful ….rite? huh cumbersome boilerplate code is avoided to do marshalling/un-marshalling steps. – converts incoming http request to our object on the fly and message body marshalling/unmarshalling with We will understand & in detail before coding & are Spring MVC annotations used to serialize/de-serialize the incoming request message & out-going response body from java object to XML/JSON and – converts return value from our object to http response (i.e. declares explicit support for annotation-driven MVC controllers (i.e.Basically these classes are annotated with on top of the class with value attribute for URL path.this tag scans all classes & sub-classes under the value of base-package attribute and register them with the container.ContextLoaderListenerīelow mvc-rest-dispatcher-servlet.xml file defines, files under this tag is the start-up page.We will see “mvc-rest-dispatcher-servlet.xml” file for our Spring MVC REST application “mvc-rest-dispatcher-servlet.xml” is the file which describes how exactly specific http requests are handled or which controllers gets invoked for certain http requests.with its attributes describes the location of the file from where it has to be loaded.name mentioned in the web.xml is mvc-rest-dispatcher, which on loading/exploding the war into the application server(Tomcat application server for our example) looks for the servlet filename called “mvc-rest-dispatcher-servlet.xml”.all http requests with wild card pattern “/” will be intercepted by the configured servlet called “DispatcherServlet” (.DispatcherServlet ).With this introduction, we will understand how we configured web.xml for our REST application in Spring MVC web.xml (the entry point –> under WEB-INF) & ) for loading the files particular to project requirements & contains respective listener. Further, it describes about the global-context and local-context param (i.e. WEB-INF under webapp –> stores web.xml & other configuration files related to web applicationįor any web application, entry point is web.xml which describes how the incoming http requests are served / processed.Maven Dependencies or Referenced Libraries –> includes jars in the classpath.src/main/resources –> all configuration files placed here.src/main/java –> create source java files under this source folder.src/test/java –> test related files, mostly JUnit test cases.Maven has to follow certain directory structure Folks who are all familiar with REST implementations and & got basic idea about Spring MVC will find easier to grasp it Technology UsedĪdd Spring-4.0.0 dependencies to the pom.xmlįolks who aren’t familiar with Maven concepts or don’t require maven for their project, can download the below jars individually from the spring site and include them in the classpathīefore moving on, let us understand the directory/package structure once you create project in Eclipse IDE.We have covered most of the annotations in Spring MVC web application in additions to this we will add few more like & annotations to develop a working REST based application With this introduction, we will see how we can implement REST web services in Spring MVC based web application for inter-platform communications Spring MVC RESTful service And in various social networking sites, REST is preferred over the matured SOAP services Normally REST is used in Mobile application development as it’s faster. REST is much simpler to develop/implement than advanced SOAP based web services. It got verbs such as GET, POST, PUT, and DELETE to identify the difference amongst different operations exposed to external world REST stands for Representational State Transfer which is a simple stateless architecture communicated over the HTTP protocol for inter-platform interaction. Now let’s explore by extending Spring MVC web application to develop RESTful web service using more annotations REST Web Service (Learn REST) In the previous articles, we have discussed about Spring MVC web application using both XML-based & annotation-based approach in detail.
