RAD 2– Spring for Vaadin without Spring Boot

In my previous blog RAD 1 – Spring for Vaadin, I have introduced the recommended way of integrating Spring and Vaadin. In this blog, I am going to use the alternative way which is without Spring Boot explained in the article“Getting started with Vaadin Spring without Spring Boot”.  This is the hardest way. I’ve configured this in the Intellij Idea 14.

  1. Create a maven archetype as explained in the Creating a Project with Intellij Idea:2.8.3 Create Maven Project.
  2. Create a new folder WEB-INF under the webapp folder.
  3. Create a applicationContext.xml under the WEB-INF folder.
  4. Now you have to add the Spring Facet to the project. You have to add the Spring Context created in the step 3. However, I first add the Spring module.

My applicationContext.xml is as follows

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
                           http://www.springframework.org/schema/beans/spring-beans.xsd
                           http://www.springframework.org/schema/context
                           http://www.springframework.org/schema/context/spring-context-4.1.xsd">

    <bean class="au.com.blogspot.ojitha.MyUI.MyConfiguration"/>
    <context:component-scan base-package="au.com.blogspot.ojitha"/>

</beans>

Here is the configuration file

package au.com.blogspot.ojitha;

import com.vaadin.ui.Button;
import com.vaadin.ui.Button.ClickEvent;
import com.vaadin.ui.Label;
import com.vaadin.ui.UI;
import com.vaadin.ui.VerticalLayout;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.context.ContextLoaderListener;

/**

@Theme("valo")
//@Widgetset("au.com.blogspot.ojitha.MyAppWidgetset")
@SpringUI("")
public class MyUI extends UI {

    @Override
    protected void init(VaadinRequest vaadinRequest) {
        final VerticalLayout layout = new VerticalLayout();
        layout.setMargin(true);
        setContent(layout);

        Button button = new Button("Click");
        button.addClickListener(new Button.ClickListener() {
            @Override
            public void buttonClick(ClickEvent event) {
                layout.addComponent(new Label("Thank you for clicking"));
            }
        });
        layout.addComponent(button);

    }

    @WebServlet(urlPatterns = "/*", name = "MyUIServlet", asyncSupported = true)
    //@VaadinServletConfiguration(ui = MyUI.class, productionMode = false)
    public static class MyUIServlet extends SpringAwareVaadinServlet {
    }

    @WebListener
    public static class MyContextLoaderListener extends ContextLoaderListener{}

    @Configuration
    @EnableVaadin
    public static class MyConfiguration {}


}

How To: GitHub projects in Spring Tool Suite

Image
The first step is sign up in the GitHub and create a  new project. For example I’ve created a new project Spring3part7 in the GitHub. Before add the projects you need to configure STS for GitHub access. For example, you need to add configuration as shown in the following picture Git local repository also important Now you are ready to pull the project from the GitHub, in the STS import menu select the following Now type the project name and click the ‘Search’ as shown in the following. However, when you select the found project click ‘Finish’ nothing will change in the STS interface. Now you are going to create real project. Here I am going to create simple utility project. This template project need to be created inside the imported GitHub project You have to give the same project name of the GitHub project as shown in the following project Now your project is ready to push. Before that you need to add ignore flag to all the folders and files except pom.xm

Spring 3 Part 7: Spring with Databases

This is the 7 th part of the Spring 3 Series . Create MySQL 5.6 database ‘payroll’, CREATE DATABASE payroll; Next create a user for example, user ‘ojitha’ CREATE USER 'ojitha'@'localhost' IDENTIFIED BY 'ojitha'; Need to grant the ‘payroll’ access to user ‘ojitha’ as shown in the following. GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP ON payroll.* TO 'ojitha'@'localhost'; You can download freeware of TOAD for MySQL from here . Let create a first table, that contains all the states in Australia. You can create a table using visually using the icon given directly below the Tables tab in the Object Explorer as shown in the above diagram. CREATE TABLE payroll.STATE ( CODE CHAR(3) ASCII COMMENT 'State code', STATE VARCHAR(30), PRIMARY KEY (CODE) ) ENGINE = InnoDB COMMENT = 'Australian states' ROW_FORMAT = DEFAULT; In the my sql console you can the newly added table using the following command SHOW
