Java bean vs Groovy bean

Java Beans.
   Generally the java bean class have a lot of variables and accessor(setter and getter) methods. The developer needs to write a setter and getter method for those variable as well as the developer explicitly needs to tell that variables and accessor methods are public. See the below example.

//The Country.java bean
public class Country {
    public String name;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

}

//The java main class
public class JavaBeanDemo {
    public static void main(String[] args) {
        Country country = new Country();
        country.setName("India");
        System.out.print(country.getName());
    }
}
The output is.
India.

Groovy Bean.
   But in Groovy it's easy because, the Groovy automatically generate accessor methods for all the class variable and by default the methods and variables have public access. See the below example.

Groovy Bean.
class Country {
    String name;
}

The main class
def country = new Country()
country.setName("India")
println country.getName()

The will print the message as.
India

Getting key/value pair from JSON object and getting variable name and value from JavaScript object.

Hi, I had faced one issue like this. I have an JSON object but I don't know any key name but I need to get the all the key and corresponding value from JSON object using client side JavaScript. Suddenly I wondered whether it's possible or not, after that I had done lot of workaround and finally got this solution. See the below example. function getKeyValueFromJSON() { var jsonObj = {a:10,b:20,c:30,d:50} ; for ( var key in jsonObj) { alert( "Key: " + key + " value: " + jsonObj[key]); } } In this example I have created the one json array as string, and converted this string into JSON object using eval() function. Using for-each loop I got all the key value from jsonObj, and finally using that key I got the corresponding value. Finally I got the alert like this, Key: a value:10 Key: b value:20 Key...

Simple Login Application Using Spring MVC and Hibernate – Part 1

I hope developers working in web application development might hear about MVC architecture. Almost all technologies provide support for MVC based web application development, but the success is based on many factors like reusable of the code, maintenance of the code, future adaption of the code, etc.., The success of the Spring MVC is “ Open for extension and closed for modification ” principle. Using Spring MVC the developers can easily develop MVC based web application. We don’t need any steep learning curve at the same time we need to know the basics of spring framework and MVC architecture. The Spring MVC consists of following important components. 1. Dispatcher servlet 2. Controller 3. View Resolver 4. Model Spring MVC - Overview The overall architecture of Spring MVC is shown here. 1. When “Dispatcher Servlet” gets any request from client, it finds the corresponding mapped controller for the request and just dispatches the request to the c...

Simple Login Application Using Spring MVC and Hibernate – Part 2

I hope you have visited my part1 of my tutorial . Let’s see the steps for integrating hibernate framework into Spring MVC. Here I have used MySQL database. I have created one database called “ springmvc ” and created one table called “ user ” with userid, username, password fields. I have inserted some records into table like this. Step 1: Creating User POJO class. We need to create a User POJO class for mapping user table. Ok let’s create it. Step 2: Creating hibernate mapping xml file for user class. In hibernate we need to create hibernate mapping xml file for all domain class for mapping into corresponding database table. Instead of creating xml file you can use annotation for mapping domain class into database table. This is my mapping xml document created for mapping our user domain class into user database table. Step 3: Creating authenticate service class. The method “verifyUserNameAndPassword” pres...
