#4 Working with Spring MVC

-
MVC stands for Model-View-Controller. MVC in spring required:

  1. Some JSP pages ( views) which need to be displayed.
  2. Controller which used to access views
  3. Model to set for views

So lets start with MVC. Before starting I hope you have idea of basic REST api development. If not then you can follow steps here.

For MVC, we need to follow steps below:

1. Create a ModelController class. Add annotation @Controller on top ( with @RestController it will not work).



2. Create JSP page, let say index.jsp. Please check hierarchy in folder structure for index.jsp page as we will require to tell our application that from where JSP pages need to pick.


3. Create HelloConfig.java to register InternalResourceViewResolver. 
InternalResourceViewResolver is used at application level to tell application path of JSP/CSS files.



I have set path to "/WEB-INF/pages" and added suffix as .jsp. So now I won't require to specify .jsp explicity. To access jsp page now I can simply write name of page.

4. Add Apache dependency in pom.xml to display JSP pages.

5. Finally write method in controller class:


In Spring boot we can simply pass jsp page name to display. 

Before Spring boot app, we were using ModelAndView object to return JSP page.

So lets try to call api after starting server:


So finally we are able to display our jsp page.

Now lets move to next step here. We will be learning how to pass arguments in ModelAndView from one page to another page.

Before starting this tutorial, I am assuming that you guys have basic idea of Spring. If you don't have basic idea of simple Spring API then no worry :), I have written simple tutorial here to start with Spring Boot . This tutorial is next version of my first tutorial . In my first tutorial I explained that how can we make a simple REST api with Spring Boot .  So lets start with JDBC connection in some very simple steps: 1. Create DB schema and table I prefer MySqlWorkBench for this purpose ( you can use any way to create schema). For this tutorial I have named my db as test_db . This DB contains one Employee table with below schema: Table contains id, name and email of employee ( This is just for tutorial, You make table as per your requirement). Once you created table, Insert some dummy data for your REST api. Your api will be fetching this data and will return it as JSON. I have made some of dummy entries as below: 2. Add Maven depen

I hope you must be familiar with Java . Spring is a Java framework which is used for Rest api development by using Java as language. If you want to have basic idea about spring then you can visit here . In this tutorial I will be focusing on simple rest api using Get method. Please follow steps below to create your first Rest api: 1. Create project schema: While creating project schema, we can simply create via eclipse by going file -> new -> Maven Project .  If we are using above method to create project schema then for Maven dependencies we will need to make entry in Pom.XML. To avoid that we can refer  start.spring.io . In this tutorial I will be creating project via this interface only. So lets avoid any more delay and start development in some very simple steps: Open website  start.spring.io  and enter group (package), Artifact (name). After this add all required dependencies. Initially we will required only Spring MVC dependency as in screenshot bel

Swift Initialization

Swift has introduced new type of variables called Optional . These are used to hold nil value in swift. Because of these variable, there are some changes regarding initialization of variables. Here are details for the same:   1. It is must to have initializer in swift if using non-optional property.   2. You need to UnWrap optional variables before using them: 3. If Property can be nil then use ? after property, before setting any value: 4. If you unwrap the property while declaring, then you can use it directly. Please note that it is not considered as good practice as it may cause crash at run time. 5.  With Swift new version, you need to implement initWithCoder method if using init method. 6. Before accessing self properties ( eg view), you must call super class method during init and initWithCoder . 7.  You can create object before calling super method and after that can assign values to that object: 8.  You can
