Nowadays sending SMS has become a common requirement for notifications, alerts and for authentications etc. There are many service provider companies which provide SMS APIs and gateways to send bulk...
The Spring Web model-view-controller is a framework which is designed on the basis of DispatcherServlet that dispatches requests to handlers, view resolution, time zone, locale, handle mappings as well as support for uploading files. With the help of SpringMVC, the controller mechanism also allows a user to create application and Web sites and applications, through the PathVariable annotation and other features.
SpringMVC framework provides an end-to-end solution for combining messaging solution providers into the application. Before using this framework you should know that itself does not provide a complete solution for messaging such as sending and receiving messages. Instead of doing this, it easily integrates applications with existing messaging solution providers. The hierarchy of framework is streamed into two parts one for the Java platform and other for the.NET platform. In this article, we only cover Java platforms and its various capabilities available in the form of classes or interfaces.
Before code section, it is important to learn about the MVC architecture that is implemented by Spring MVC. This pattern separates the logic of a program from its representation. This model is capable of doing stuff like calculate data, save things and work with user input. The MVC keeps changes the view of the application and modifies it time to time so that it looks attractive to viewers. These component work together in Spring MVC to create a responsive and dynamic application.
We’re going to use the MSG91 Java SDK to integrate into the application. Since this library function is available from a public Maven repository, you only need to do use the SDK to update pom.xml file. This file is used to build our project and manage its responsibilities.
The Message class in Spring MVC conforms to MVC standards and then represents the SMS that an application can send or receive. But this application can not directly deal with its class. There are many helper classes are available for handle the data encapsulation in the message. The MessageProperties are closely associated with the Message class which describes the various properties of the message. The application that produces messages is able to send a message to the exchange in plenty of ways and the one that we have already seen is to call the method convertAndSend() defined on the RabbitTemplate object. For example, if we want to post the process of message once it is created, after that we post-processor that can define custom message for achieving that for example
In this class, we have to set application ID on the message object before sending it by attaching a custom message post processor object. This method is usually used when the message comes from a different source and then the current application has to change the properties of the message. In that condition, it is good to mention the routing key of a source that will represent the exchange destination to which the message has to be sent. This property will override the routing key on the Rabbit Template object.
