Spring MVC & Jquery Ajax - Part 1 - The project

Welcome to the first part of the video class on Spring MVC and jQuery Ajax . During these video classes I will teach a little of how we work with ajax requests in Java applications with Spring MVC and also, jQuery Ajax. I going to create an app in Netbeans. For that, I added in the blog post a download link, where you must download this file, which contains some files that whoud take a little more time to set them during this video class. So to save a little time, I've I left these files available to you. When I need these files I will show where we must added them. Then, firstly we going to create a project. The project is a maven project. Then, you need to select the maven option. Web application. we will name it as spring-ajax, ... okay! ... Pay attention in this package... that we created here. I going to select Apache Tomcat JEE 6. Now, we will finalize and waiting that the Netbeans create the project, to us. So, the first thing that I going to make, will be update the dependences of the maven file. Thus, we will have access to Spring and also to Hibernate Framework works with database persistence and some other libraries. For that, You'll open the pom.xml file and copy all dependencies. ... Now, you'll paste all these dependencies here ... ... okay! This is a default dependence that Netbeans added when we created our project. It is Java EE 6, and it'll provide to us the access to the other libraries from Java EE 6 like, for example, the part of Servlets. For the Spring we will use the spring-context, the spring-webmvc, the spring-orm to use the Hibernate and the part of transactions, like spring transaction (spring-tx). Jacson dependence is important, it will be... the communication between our Ajax requests using jQuery and the Spring MVC. The library JSTL, it will work in our JSP pages.. Here, we have the Hibernate dependencies. And the MySQL driver, the database connector that it will added in our project. We going to save and close this file. Now, you going to web pages... (I going to close this) ... and we'll add a new folder called WEB-INF. Return to, downloaded files and copy all these files: spring-context, spring-dao, spring-servlet and web.xml. After that, paste them into the WEB-INF folder. The spring-context is the responsible file for Spring Framework initialization. We will work with annotations, so I add the base package, where we will put the spring annotations. In this case, it will be com.mballem ... I think that I had created the spring ajax package, so I will update here to spring.ajax This config will indicate to Spring that we will work with MVC annotations. And here we'll import the files of spring-servlet and spring-dao. Spring-servlet is the config to Spring has access and to work with jsp pages. In this case, into the WEB-INF folder we going to create a folder called "views". This folder will be where our JSP pages are stored. So, the Spring going to find all JSP pages in that folder. The tag mvc-resource, will be where I will add the javascript file and also the css file that we'll use in our JSP pages. In spring-dao file, we have configured the datasource. You must remind to create the database in your MySQL GDB. The database's name is sprig-ajax. Put here, the password, But if you already have your Mysql with another user or password, change here. The other settings are the Hibernate. Nothing much different from what you should be accustomed to working with Spring. And the SessionFactory, to finalize, what it is important for us to work. I'm using Hibernate 4 to work with the SessionFactory. In web.xml file... ... then, we have the basic settings from web.xml to work together with Spring, also nothing much different from the usual. Into WEB-INF file, we will create a new folder called "views". And here, into web pages we'll create a page called "resources", excuse me, this is a folder not a page. Within of "resources", we'll create a 'css' folder and a 'js' folder. Within of 'css' folder paste the file: style.css. Then, here has a css style that we'll use in our JSP pages. Now, we will start to create our Java classes. The first thig that I'll do is create a package called 'entity'. And after a class called 'Contact'. So, in the next video classe we will continue developing the Contact class See you!
