How to Create Hibernate Project?

Posted on by coder

1- Create a netbeans JAVA project.

2- Add Library   “Hibernate JPA ”

3- Right click project   >  Create new  Hibernate Config > Hibernate.cfg

Write Connection parameters then test your  Connection.

Connection Properties,   Then create “Hibernate…cfg”

This hibernate configuration file location usually located at the root directory.

 

For example

”    javakLibsrcHibernate.cfg”

 

4- We need to create  .Class  for the Fields of the  database.Table.

There are 2 options

First :  is  set the fields by XML file

Second : is set the fields properties inside of java file.  Which method name is Annotation

 

Example .java Class for the Fields

package hibernate;


import java.io.Serializable;
import javax.persistence.Column;
import javax.persistence.Table;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.UniqueConstraint;
@Entity
@Table(name="tmp_hibernate",uniqueConstraints={@UniqueConstraint(columnNames={"id"})})
public class customer implements Serializable {

    @Id
    @GeneratedValue(strategy=GenerationType.IDENTITY)
    @Column(name="id", nullable=false, unique=true, length=11)
    private Integer id;
    
    @Column(name="bayi_kodu", length=20, nullable=true)
    private int bayi_kodu;
    
    @Column(name="email", length=20, nullable=true)
    private String email;
    
    @Column(name="uname", length=20, nullable=true)
    private String username;

    
    public int getid() {
        return this.id;
    }
    public void setid(int id) {
        this.id = id;
    }

With this annotation file  we need to  set  location of  this file as a mapping inside of  Hibernate |Config .

Package name is   hibernate

Class name is   customer

 




  
    org.hibernate.dialect.MySQLDialect
    com.mysql.jdbc.Driver
    jdbc:mysql://xxxxxx:3306/DatabaseNAME?zeroDateTimeBehavior=convertToNull
    USERNAME
    PASSWORD
    
         
        
        thread

If you are not using annotation  method,  you need to define Field types inside of .xml file then you need to give xml path to   Hibernate.cfg file

BuildSessionFactory

 

Example   Util.java  for  hibernate

package hibernate;

import java.util.Properties;
import org.hibernate.SessionFactory;
import org.hibernate.boot.registry.StandardServiceRegistryBuilder;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;

public class util {

    private static SessionFactory sessionFactory = buildSessionFactory();

    /**
     * @return 
     */
    private static SessionFactory buildSessionAnnotationFactory() {
        try {
            // Create the SessionFactory from hibernate.cfg.xml
            Configuration configuration = new Configuration();
            configuration.configure("hibernate.cfg.xml");
            System.out.println("Hibernate Annotation Configuration loaded");

            ServiceRegistry serviceRegistry = new StandardServiceRegistryBuilder().applySettings(configuration.getProperties()).build();
            System.out.println("Hibernate Annotation serviceRegistry created");

            SessionFactory sessionFactory = configuration.buildSessionFactory(serviceRegistry);

            return sessionFactory;
        } catch (Throwable ex) {
            // Make sure you log the exception, as it might be swallowed
            System.err.println("Initial SessionFactory creation failed." + ex);
            throw new ExceptionInInitializerError(ex);
        }
    }

    private static SessionFactory sessionAnnotationFactory;
    public static SessionFactory getSessionAnnotationFactory() {
        if(sessionAnnotationFactory == null) sessionAnnotationFactory = buildSessionAnnotationFactory();
        return sessionAnnotationFactory;
    }
    
    public static void shutdown() {
        // Close caches and connection pools
        sessionFactory.close();
    }
    public static SessionFactory getSessionFactory() {
        if(sessionFactory == null) sessionFactory = buildSessionFactory();
        return sessionFactory;
    }

}

 

5- Testing,

import hibernate.customer;
import hibernate.util;
import org.hibernate.Session;
import net.sf.ehcache.hibernate.HibernateUtil;
import org.hibernate.SessionFactory;

hibernate.customer Member_YENI = new customer();
Member_YENI.setbayi_kodu(14);
Member_YENI.setemail("coder@gmail.com");
Member_YENI.setusername("kutayzorlu");
        

SessionFactory sessionFactory =
hibernate.util.getSessionAnnotationFactory();

Session session = sessionFactory.getCurrentSession();
session.beginTransaction();
session.save(Member_YENI);
session.getTransaction().commit();

// This is  Static defined inside of  utility
util.shutdown();

Maven, What is Maven? , What is Maven doing?

Posted on by coder

Convention over configuration (also known as coding by convention) is a software design paradigm which seeks to decrease the number of decisions that developers need to make, gaining simplicity, but not necessarily losing flexibility.

The phrase essentially means a developer only needs to specify unconventional aspects of the application. For example, if there is a class Sale in the model, the corresponding table in the database is called “sales” by default. It is only if one deviates from this convention, such as calling the table “product sales”, that one needs to write code regarding these names.

When the convention implemented by the tool matches the desired behavior, it behaves as expected without having to write configuration files. Only when the desired behavior deviates from the implemented convention is explicit configuration required.

Aspect oriented programming (AOP)

Posted on by coder

In computing, aspect-oriented programming (AOP) is a patented[1] programming paradigm that aims to increase modularity by allowing the separation of cross-cutting concerns. It does so by adding additional behavior to existing code (an advice) without modifying the code itself, instead separately specifying which code is modified via a “pointcut” specification, such as “log all function calls when the function’s name begins with ‘set'”. This allows behaviors that are not central to the business logic (such as logging) to be added to a program without cluttering the code core to the functionality. AOP forms a basis for aspect-oriented software development.

AOP includes programming methods and tools that support the modularization of concerns at the level of the source code, while “aspect-oriented software development” refers to a whole engineering discipline.

Aspect-oriented programming entails breaking down program logic into distinct parts (so-called concerns, cohesive areas of functionality). Nearly all programming paradigms support some level of grouping and encapsulation of concerns into separate, independent entities by providing abstractions (e.g., functions, procedures, modules, classes, methods) that can be used for implementing, abstracting and composing these concerns. Some concerns “cut across” multiple abstractions in a program, and defy these forms of implementation. These concerns are called cross-cutting concerns.

Logging exemplifies a crosscutting concern because a logging strategy necessarily affects every logged part of the system. Logging thereby crosscuts all logged classes and methods.

All AOP implementations have some crosscutting expressions that encapsulate each concern in one place. The difference between implementations lies in the power, safety, and usability of the constructs provided. For example, interceptors that specify the methods to intercept express a limited form of crosscutting, without much support for type-safety or debugging. AspectJ has a number of such expressions and encapsulates them in a special class, an aspect. For example, an aspect can alter the behavior of the base code (the non-aspect part of a program) by applying advice (additional behavior) at various join points (points in a program) specified in a quantification or query called a pointcut (that detects whether a given join point matches). An aspect can also make binary-compatible structural changes to other classes, like adding members or parents.

 

void transfer(Account fromAcc, Account toAcc, int amount, User user,
    Logger logger) throws Exception {
  logger.info("Transferring money…");
 
  if (!isUserAuthorised(user, fromAcc)) {
    logger.info("User has no permission.");
    throw new UnauthorisedUserException();
  }
 
  if (fromAcc.getBalance() < amount) {
    logger.info("Insufficient funds.");
    throw new InsufficientFundsException();
  }
 
  fromAcc.withdraw(amount);
  toAcc.deposit(amount);
 
  database.commitChanges();  // Atomic operation.
 
  logger.info("Transaction successful.");
}

 

 

Spring Modules

Java spring modules list

  • Spring Core Container: This is the base module of Spring and provides spring containers (BeanFactory and ApplicationContext).[6]
  • Aspect-oriented programming: enables implementing cross-cutting concerns.
  • Authentication and authorization: configurable security processes that support a range of standards, protocols, tools and practices via the Spring Security sub-project (formerly Acegi Security System for Spring).
  • Convention over configuration: a rapid application development solution for Spring-based enterprise applications is offered in the Spring Roo module
  • Data access: working with relational database management systems on the Java platform using JDBC and object-relational mapping tools and with NoSQL databases
  • Inversion of control container: configuration of application components and lifecycle management of Java objects, done mainly via dependency injection
  • Messaging: configurative registration of message listener objects for transparent message-consumption from message queues via JMS, improvement of message sending over standard JMS APIs
  • Model–view–controller: an HTTP- and servlet-based framework providing hooks for extension and customization for web applications and RESTful Web services.
  • Remote access framework: configurative RPC-style marshalling of Java objects over networks supporting RMI, CORBA and HTTP-based protocols including Web services (SOAP)
  • Transaction management: unifies several transaction management APIs and coordinates transactions for Java objects
  • Remote management: configurative exposure and management of Java objects for local or remote configuration via JMX
  • Testing: support classes for writing unit tests and integration tests
