JSF SpringMVC Hibernate Integration Example Tutoria with maven

According to spring MVC structure, we can create three layers in our project

1. DAO Layer
2. Service Layer
3. Model Layer

This is Project structure

Firstly configure all XML file. It will help to continue your project without errors.

faces-config.xml

</plugins> </build> </project>


Step 03 - Create Controller class(SpringBootController.java)

package com.boraji.tutorial.springboot.controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; @RestController public class SpringBootController{ @RequestMapping("/") public String sayHello() { return "Hello Spring Boot!!"; } }

Spring Boot - Hello world example

This sample explains how to create spring boot hello world application

Tools and technologies used for this application are-

• Spring Boot 1.5.4.RELEASE
• JavaSE 
• Maven
• Eclipse Neon

Here is project Structure

Step 01 - Create Maven project

File -> New -> Maven Project ->select Create a simple project ->Enter details and finish.

Step 02 - Add dependencies to pom.xml file

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.boraji.tutorial.springboot</groupId> <artifactId>spring-boot-hello-world-example</artifactId> <version>0.0.1-SNAPSHOT</version> <properties> <java.version>1.8</java.version> </properties> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.5.4.RELEASE</version> </parent> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>

Step 03 - Create Controller class(SpringBootController.java)

package com.boraji.tutorial.springboot.controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; @RestController public class SpringBootController{ @RequestMapping("/") public String sayHello() { return "Hello Spring Boot!!"; } }

Step 04 - Create Main Class(MainApplication.java)

package com.boraji.tutorial.springboot; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication public class MainApplication{ public static void main(String[] args) { SpringApplication.run(MainApplication.class, args); } }

Step 05 - Run Application

Right click on MainApplication.java - > Run As -> Java Application

Step 06 - Get Output

Now, enter the http://localhost:8080 in browser's address bar and see the output

Garbage collection

Singleton in same package same class,


package com.singletone.test;


class SingletoneBorn{

private static SingletoneBorn instanse = new SingletoneBorn();

private SingletoneBorn(){}

public static SingletoneBorn getInstanse() {
return instanse;
}

public void showDetails(){
System.out.println("This is singletone born world");
}
}

public class SingletoneTest {

public static void main(String args[]){
SingletoneBorn sb = SingletoneBorn.getInstanse();
sb.showDetails();

}


}

Singleton same package different class


Singleton class

package com.singletone.test;

public class SingletoneTest {


private static SingletoneTest instanse = new SingletoneTest();

private SingletoneTest(){}

public static SingletoneTest getInstanse() {
return instanse;
}

public void showDetails(){
System.out.println("This is singletone born world");
}

}

Singleton usage class

package com.singletone.test;

public class TestSingletone {
public static void main(String args[]){

SingletoneTest st = SingletoneTest.getInstanse();
st.showDetails();
}


}

Singleton different package different class


Singleton class

package com.singletone.test;

public class SingletoneTest {


private static SingletoneTest instanse = new SingletoneTest();

private SingletoneTest(){}

public static SingletoneTest getInstanse() {
return instanse;
}

public void showDetails(){
System.out.println("This is singletone born world");
}

}

Singleton usage class

package com.singletone.test2;

import com.singletone.test.SingletoneTest;

public class SingleTest {

public static void main(String args[]){
SingletoneTest st = SingletoneTest.getInstanse();
System.out.println("Singletone method call in nother package");
st.showDetails();
}

</html>

main.html file

<html lang="en">

<head>

 <script src="http://code.jquery.com/jquery-1.9.1.js"></script>

 <script>

$(document).ready(function() {

$('#result').load('content.html #new-projects', function() {

Run this as localhost/path/main.html
