Merhabalar, bu yazı RESTful (JAX-RS) web servisleri üzerine bir örnek olacaktır. İçerikten bahsetmek gerekirse projeyi oluşturma, veritabanını tasarlama, DAO katmanının yazılması, Rest Servislerin yazılmasını ve hatta hazırladığınız Rest Servise ait istemcinin nasıl yazılacağına kadar bir çok konuyu kapsayacaktır.

İÇİNDEKİLER

Projenin Oluşturulması
Veritabanının Oluşturulması
Veritabanı modellerinin oluşturulması
DAO Sınıfının Yazılması
Web Servislerinin Yazılması
Web Servis için İstemcinin yazılması

1. HAZIRLIK

Tüm proje Eclipse IDE altında geliştirilecektir. Ayrıca geliştirme sırasında sunucu olarak MySQL ve Tomcat v7.0 kullanılacaktır. RESTful Web servisleri için, JAX-RS uygulaması olarak Jersey kullanılacaktır. İsterseniz başka JAX-RS uygulamaları da kullanabilirsiniz. Projenin lifecycle’ı maven tarafından yönetilecektir. Bu sebepten M2E eklentisini kullanmanız tavsiye edilir.

Projede izleyeceğimiz senaryo, Restaurantlar için bir rezervasyon sistemi yazılacağını düşünelim . Arayüzü destekleyecek verilerin çekilmesinden, sistemi kullanacak firmaların kaydını yapmaktan ve sisteme kayıtlı firmalar için rezervasyon kaydı tutmaktan sorumlu Web Servisi yazma işi ve veritabanının tasarlanması bu projede bize verilmiş olsun.

1.1 Projeyi oluşturma

Eclipse üzerinden bir Dynamic Web Projesi create ediyoruz. Projeyi create ettikten sonra sağ click yaparak projeyi Maven projesine çeviriyoruz.

Eclipse altında yarattığımız proje de, pom.xml dosyanızı açın. Burada yapmamız gereken tüm projeler için ortak olacak bağımlılıkları, build komutlanırı, raporlama komutlarını girmek.

1.1.1 Bağımlılıklar

İlk önce proje genelinde kullanacağımız bağımlılıkları ekleyelim. Bu bağımlılıkları istediğimiz zaman gelip değiştirebiliriz. Bağımlılıkları eklemek için aşağıdakileri, dependencies tabının altına kopyalamaniz yeterlidir.

1.2 Veritabanının Tasarlanması

Veritabanı iki farklı tablodan oluşacak. Bunlardan biri User tablosu. Örnek projemizdeki Rezervasyon yapacak müsterileri temsil edecek. Diğeri ise sisteme kayıtlı Restaurant Firmaları tablosu. Bir diğeri ise Rezervasyon bilgilerini tuttuğumuz Rezervasyon tablosu. Bunun için öncelikle veritabanı şemamızı oluşturuyoruz. Ben örnekte MySQL veritabanı kullanacağım. Siz istediğiniz veritabanını seçmekte özgürsünüz. Kullanacağımız şema companyrezdb olsun.

1.2.1 User tablosunun oluşturulması

CREATE TABLE `user` (
  `userId` int(11) NOT NULL AUTO_INCREMENT,
  `userNumber` int(11) DEFAULT NULL,
  `userName` varchar(45) COLLATE utf8_bin DEFAULT NULL,
  `userSurname` varchar(45) COLLATE utf8_bin DEFAULT NULL,
  PRIMARY KEY (`userId`)
) ENGINE=InnoDB AUTO_INCREMENT=61 DEFAULT CHARSET=utf8 COLLATE=utf8_bin;

CREATE TABLE `user` (

`userId` int(11) NOT NULL AUTO_INCREMENT,

`userNumber` int(11) DEFAULT NULL,

`userName` varchar(45) COLLATE utf8_bin DEFAULT NULL,

`userSurname` varchar(45) COLLATE utf8_bin DEFAULT NULL,

PRIMARY KEY (`userId`)

) ENGINE=InnoDB AUTO_INCREMENT=61 DEFAULT CHARSET=utf8 COLLATE=utf8_bin;

1.2.2 Rezervasyon tablosunun oluşturulması

Rezervasyon tablosundaki her rezervasyon kaydı bir kullanıcıya ait olmalı. Bunun için Rezervasyon tablosu ile User tablosu arasında 1->N bir ilişki olmalıdır. Rezervasyon tablosunu bu özelliklerle aşağıdaki gibi oluşturuyoruz.

CREATE TABLE `rezervasyon` (
  `id` int(11) DEFAULT NULL,
  `state` varchar(20) CHARACTER SET utf8 COLLATE utf8_bin DEFAULT NULL,
  `companyId` int(11) DEFAULT NULL,
  `ekstraHizmet` varchar(45) CHARACTER SET utf8 COLLATE utf8_bin DEFAULT NULL,
  KEY `companyId` (`companyId`),
  CONSTRAINT `companyId` FOREIGN KEY (`companyId`) REFERENCES `user` (`userid`) ON DELETE CASCADE ON UPDATE CASCADE

CREATE TABLE `rezervasyon` (

`id` int(11) DEFAULT NULL,

`state` varchar(20) CHARACTER SET utf8 COLLATE utf8_bin DEFAULT NULL,

`companyId` int(11) DEFAULT NULL,

`ekstraHizmet` varchar(45) CHARACTER SET utf8 COLLATE utf8_bin DEFAULT NULL,

KEY `companyId` (`companyId`),

CONSTRAINT `companyId` FOREIGN KEY (`companyId`) REFERENCES `user` (`userid`) ON DELETE CASCADE ON UPDATE CASCADE

1.2.3 Firma tablosunun oluşturulması

Sisteme rezervasyon yapılacak firmaları eklemek için oluşturuyoruz.

CREATE TABLE `company` (
  `companyId` int(11) NOT NULL,
  `companyName` varchar(45) COLLATE utf8_bin DEFAULT NULL,
  `companyDistance` varchar(20) COLLATE utf8_bin DEFAULT NULL,
  `companyService` varchar(45) COLLATE utf8_bin DEFAULT NULL,
  `companyServiceTime` varchar(20) COLLATE utf8_bin DEFAULT NULL,
  PRIMARY KEY (`companyId`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_bin;

CREATE TABLE `company` (

`companyId` int(11) NOT NULL,

`companyName` varchar(45) COLLATE utf8_bin DEFAULT NULL,

`companyDistance` varchar(20) COLLATE utf8_bin DEFAULT NULL,

`companyService` varchar(45) COLLATE utf8_bin DEFAULT NULL,

`companyServiceTime` varchar(20) COLLATE utf8_bin DEFAULT NULL,

PRIMARY KEY (`companyId`)

) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_bin;

2. Veritabanı Modellerinin Hazırlanması

2.1 Employee.java classının oluşturulması

Veritabanındaki User tablomuz için pojo sınıfımızı oluşturalım.

package com.aysenur.model;

import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement (name ="employee") // <employee> tag'ları arasına xml elemenleri yerleştirilir.

	public class Employee {


		private int employeeiId;
		private int employeeNo;
		private String employeeName;
		private String employeeSurname;
		
		public Employee() {
		}

		public Employee(int employeeiId, int employeeNo, String employeeName, String employeeSurname) {
			
			this.employeeiId = employeeiId;
			this.employeeNo = employeeNo;
			this.employeeName = employeeName;
			this.employeeSurname = employeeSurname;
		}
		@XmlElement
		public int getEmployeeiId() {
			return employeeiId;
		}

		public void setEmployeeiId(int employeeiId) {
			this.employeeiId = employeeiId;
		}
		@XmlElement
		public int getEmployeeNo() {
			return employeeNo;
		}

		public void setEmployeeNo(int employeeNo) {
			this.employeeNo = employeeNo;
		}
		@XmlElement
		public String getEmployeeName() {
			return employeeName;
		}

		public void setEmployeeName(String employeeName) {
			this.employeeName = employeeName;
		}
		@XmlElement
		public String getEmployeeSurname() {
			return employeeSurname;
		}

		public void setEmployeeSurname(String employeeSurname) {
			this.employeeSurname = employeeSurname;
		}
		@Override
		public String toString() {
			return "Employee [employeeiId=" + employeeiId + ", employeeNo=" + employeeNo + ", employeeName="
					+ employeeName + ", employeeSurname=" + employeeSurname + "]";
		}
	
}

package com.aysenur.model;

import javax.xml.bind.annotation.XmlElement;

import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement (name ="employee") // <employee> tag'ları arasına xml elemenleri yerleştirilir.

public class Employee {

this.employeeSurname = employeeSurname;

}

@XmlElement

this.employeeNo = employeeNo;

}

@XmlElement

public String getEmployeeName() {

return employeeName;

}

public void setEmployeeName(String employeeName) {

this.employeeName = employeeName;

}

@XmlElement

public String getEmployeeSurname() {

return employeeSurname;

}

public void setEmployeeSurname(String employeeSurname) {

this.employeeSurname = employeeSurname;

}

@Override

public String toString() {

return "Employee [employeeiId=" + employeeiId + ", employeeNo=" + employeeNo + ", employeeName="

+ employeeName + ", employeeSurname=" + employeeSurname + "]";

}

2.1.2 Company.java classının oluşturulması

public class Company {
	
	int companyId;
	String companyName;
	String companyDistance;
	String companyService;

	public Company() {}

	public Company(int companyId, String companyName, String companyDistance, String companyService,
			String companyServiceTime) {
		super();
		this.companyId = companyId;
		this.companyName = companyName;
		this.companyDistance = companyDistance;
		this.companyService = companyService;
		this.companyServiceTime = companyServiceTime;
	}

	public int getCompanyId() {

	}

	public void setCompanyService(String companyService) {
		this.companyService = companyService;
	}

	public String getCompanyServiceTime() {
		return companyServiceTime;
	}

	public void setCompanyServiceTime(String companyServiceTime) {
		this.companyServiceTime = companyServiceTime;
	}

}

package com.aysenur.model;

/**

}

public void setCompanyId(int companyId) {

this.companyId = companyId;

}

public String getCompanyName() {

return companyName;

}

public void setCompanyName(String companyName) {

this.companyName = companyName;

}

this.companyService = companyService;

}

public String getCompanyServiceTime() {

return companyServiceTime;

}

public void setCompanyServiceTime(String companyServiceTime) {

this.companyServiceTime = companyServiceTime;

}

2.1.3 Rezervasyon modelinin oluşturulması

package com.aysenur.model;

public class Rezervasyon {

	int id;
	int companyId;
	String state;
	String ekstservice;
	String note;
	public Rezervasyon() {
		
	}
	public Rezervasyon(int id, int companyId, String state, String ekstservice, String note) {

		this.ekstservice = ekstservice;
		this.note = note;
	}
	
	
	public int getId() {

this.ekstservice = ekstservice;

}

public String getNote() {

return note;

}

public void setNote(String note) {

this.note = note;

}

3. DAO Sınıflarının oluşturulması

Öncelikle tüm DAO sınıflarında ortak olan, metodları belirleyeceğiz. Bu metodları bir interface sınıfına çıkartacağız. Ardından yine tüm DAO sınıflarında ortak olarak kullanılacak metodları uygulayacağız. Ardından her bir model için DAO sınıflarını oluşturacağız. Oluşturacağımız interface’te CRUD işlemleri olacak.

package com.aysenur.dao;

import java.sql.Connection;
import java.util.List;


public interface IBaseDao<T> {
	
	public Connection connectionToDatabase(); 
	public List<T> dataRead();
	public T dataRead(int t);
	public boolean dataAdd(T t);
	public boolean dataEdit(T t, int a);
	public boolean dataDelete(int t);
}

package com.aysenur.dao;

import java.sql.Connection;

import java.util.List;

public interface IBaseDao<T> {

public Connection connectionToDatabase();

public List<T> dataRead();

public T dataRead(int t);

public boolean dataAdd(T t);

public boolean dataEdit(T t, int a);

public boolean dataDelete(int t);

}

3.1 Company modelimiz için CompanyDAO sınıfı :

package com.aysenur.dao.impl;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.util.ArrayList;

			}

		} catch (Exception e) {

	}

	@Override

						  resultSet.getString(3), resultSet.getString(4),resultSet.getString(5));

				companys.add(company);
			}

		} catch (Exception e) {
			System.out.println("HATA: " + e);
		}
		  
		  for (int i = 0; i < companys.size(); i++) { Object obj =
		  companys.get(i).getCompanyId() + " " + companys.get(i).getCompanyName() + " " +
		  companys.get(i).getCompanyService() + " " +
		  companys.get(i).getCompanyDistance()+" "+companys.get(i).getCompanyServiceTime();
		  
		  System.out.println(obj); }
		  
		  return companys; }

	@Override 
	public Company dataRead(int firmaId) {
		  connectionToDatabase();
		  
		  Company company = null;
		  
		  try {
		  
		  String sorgu = "SELECT * FROM company WHERE cId=? company";
		  PreparedStatement preparedStatement = con.prepareStatement(sorgu);

}

Evet servisimizi de yukarıdaki gibi yazdık. Biraz da neyin ne olduğunu incelemeye başlayalım. POST, DELETE, EDIT ve GET metodlarını kullandık. Kullanıcı silme işlemleri için DELETE tipinde HTTP Request’ler bekleniyor aynı şekilde Kullanıcı bilgilerini düzenlemek için EDIT sisteme Kullanıcı ve Firma eklemek için POST kullandık. Veri tabanında ki verilere erişmek istediğimiz de GET kullandık. GET metodlarınızı tarayıcınız üzerinden deneyebilirsiniz. Örnek bir kaç adresi aşağıda veriyorum.

Sisteme kayıtlı tüm kullanıcıları görmek için :

http://localhost:9999/_RESTful_JDBC_CRUD/rest/employee/all

Sisteme kayıtlı tüm Firmaları görmek için :

http://localhost:9999/_RESTful_JDBC_CRUD/rest/company/all

Sisteme kayıtlı varsa 12 numaralı kullanıcıyı görmek için :

http://localhost:9999/_RESTful_JDBC_CRUD/rest/employee/12

Evet, artık web servisimizi de tamamladık. Burdan sonra bu geliştirdiğimiz web servisimize özel istemcileri nasıl yazacağımız kaldı.

Takip edemeyenler ve projenin son halini merak edenler için projenin git deposu aşağıdaki gibidir.
Projeleri yaratırken sorun yaşadıysanız, proje yapısına Git Repo’sundan bakabilirsiniz.
