JSF Projesine Spring Framework ve Hibernate(Oracle JDBC) kurulumu(Resimli Anlatım)
Merhaba, JSF Spring Framework ve Hibernate projesi yapacağım.
Gerekenler(Daha önce yaptığımız adımlar)
1 ) Tomcat Kurulumu ( Yazıyı Oku ) ben 9 versiyonunu kurdum
2 ) JSF projesi oluşturma ( Yazıyı Oku )
3 ) JSF projesi üzerine Primefaces araçları eklenmesi ( Yazıyı Oku )
JSF HelloPrimefaces projemizin üstüne Spring Framework ve Hibernate ekleyeceğim bunun için 3. yazıdaki projeyi indirebilir yada ilk 3 adımı yaparak yeni bir proje oluşturabilirsiniz(Tavsiye Ederim).
1 ) POM XML DÜZENLENMESİ
Öncelikle Pom xml dosyamıza Spring Framework , Hibernate ve Oracle JDBC kütüphanelerimizi ekleyelim.
Maven dependency versiyon güncelleme kolay olması için(Spring ve Hibernate için) properties içinde(Değişken olarak atama diyebiliriz) tanımladım.UTF8 standartını da kullandım.
<properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <org.springframework.version>4.3.10.RELEASE</org.springframework.version> <hibernate.version>5.2.10.Final</hibernate.version> </properties>

<!-- Server Saving Mode --> <context-param> <param-name>javax.faces.STATE_SAVING_METHOD</param-name> <param-value>server</param-value> </context-param>
Faces Config dosyası eklenilmeli (web xmlde belirttiğimiz isimde)
<faces-config xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-facesconfig_2_2.xsd" version="2.2">
<application>
<el-resolver>
org.springframework.web.jsf.el.SpringBeanFacesELResolver
</el-resolver>
</application>
</faces-config>
Application Context dosyası eklenilmeli (web xmlde belirttiğimiz isimde)
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.3.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd">
<import resource="beans-atakan-coban.xml" />
<import resource="hibernate_configration.xml" />
<context:annotation-config />
<context:component-scan base-package="com.atakancoban" />
</beans>
Application Context içinde beans-atakan-coban.xml ve hibernate_configration.xml import edildi.Sınıfları hangi paket altında arayacağını da belirttim. com.atakancoban şeklinde. Burada http://www.springframework.org/schema/beans/spring-beans-4.3.xsd şeklindeki xsd kısımları POM xmlde spring versiyonum 4.3 olduğu için 4.3 değişik versiyon ise burada da güncellemek gerekir.
Beans xml(beans-atakan-coban.xml) Bu dosyada Spring Dao ve Dao implement classlarımızı nasıl ilişkilendireceğini belirtiyoruz ve Session Factory property özelliğini ekleyerek uygulama açıldığında Session(Connection) alıp veri tabanı işlerimizi yapabiliyoruz.Ben örnek olarak CarDao ve CarDaoImpl sınıflarımı ilişkilendirdim ve CarDao ile veritabanı bağlantısı yaptım. http://www.springframework.org/schema/beans/spring-beans-4.3.xsd burada da xsd 4.3 olarak görülmekte.
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.3.xsd"> <bean id="carDao" name="carDao" class="com.atakancoban.dao.CarDaoImpl" > <property name="sessionFactory" ref="sessionFactory" /> </bean> </beans>
Hibernate Configuration (xsd kısımları burada da 4.3 şeklinde)
Burada Hibernate Transaction manager ve Session Factory tanımlaması yaptım.
Buradaki sessionFactory beans xml kısmında dao ve daoImpl bağladığımız propertydeki sessionFactory.
Buradaki connection’ı dao sınıfımıza yolluyoruz aslında.
testcon.xml dosyasını burada gösterdim.(Connection bilgileri bu xmlde)
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.3.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.3.xsd"> <tx:annotation-driven transaction-manager="transactionManager" /> <bean id="transactionManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory" /> </bean> <bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean"> <property name="configLocation"> <value>file:testcon.xml</value> </property> </bean> </beans>
TestCon.xml
Veritabanı ile bağlantı kurmak için gerekli bilgilerin girildiği xml.
connection ip ve username password alanlarını kendi veritabanı bilgilerinizi girmelisiniz
<?xml version="1.0" encoding="utf-8"?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory name="sessionFactorySRC"> <property name="dialect">org.hibernate.dialect.Oracle10gDialect</property> <property name="connection.driver_class">oracle.jdbc.OracleDriver</property> <property name="connection.url">jdbc:oracle:thin:@ipadresiniz:1521:HELLO</property> <property name="connection.username">USERNAME GİRİNİZ</property> <property name="connection.password">PASSWORD GİRİNİZ</property> <property name="hibernate.connection.provider_class">org.hibernate.c3p0.internal.C3P0ConnectionProvider</property> <property name="hibernate.c3p0.acquire_increment">1</property> <property name="hibernate.c3p0.idle_test_period">0</property> <property name="hibernate.c3p0.min_size">1</property> <property name="hibernate.c3p0.max_size">15</property> <property name="hibernate.c3p0.timeout">0</property> <property name="show_sql">false</property> <property name="query.substitutions">true 1, false 0, yes 'Y', no 'N'</property> </session-factory> </hibernate-configuration>
Burada dikkat etmemiz gereken Tomcat Server testcon.xml dosyasını Launch Configuration ayarındaki yerde arar. Bunu ayarlayalım.Bu xml dosyasını tomcatinizin baska çalışma ortamı var ise oraya da atabilirsiniz.Ben projemin içinde xml in olduğu yolu lokasyon olarak verdim.
Şu şekilde
Tomcat Server’ın üzerine çift tıklayalım
Açılan ayarlar sayfasında Open Launch Configuration menüsüne tıklayalım
Edit Configuration penceresinde Arguments menüsüne gelelim ve aşağıdaki Working Directory kısmında workspace butonuna basarak WEB INF klasorunu belirtelim.
3 JAVA SINIFLARINDA SERVICE VE DAO KULLANIMI
DAO ve DAO Implement
CarDao şeklinde bir interface oluşturdum.
package com.atakancoban.dao;
import java.util.List;
public interface CarDao {
public List<String> getCarDetails();
public String getSystemTime() throws Exception;
}
CarDaoImpl şeklinde CarDao sınıfını implemen eden sınıf oluşturdum
Burada Spring Frameworke bu sınıfın dao sınıfı olduğunu tanımladım @Repository(“carDao”) Buradaki carDao ismi beans-atakan-coban.xml configinde ilişkilendirme kısmında kullandığım id alanı oluyor.

}
CarService ve CarServiceImpl
CarService isminde bir interface oluşturdum
package com.atakancoban.service;
import java.util.List;
public interface CarService {
public List<String> getCarDetails();
public String getSystemTime() throws Exception;
}
CarServiceImpl isminde CarService implement eden sınıf oluşturdum
package com.atakancoban.service;
import java.util.ArrayList;
import java.util.List;
import javax.xml.bind.annotation.XmlTransient;

else{
System.out.println("carDaou service icinde null");
return null;}
}
/* @Transactional(rollbackFor = Exception.class, readOnly = false)
public addname() {

public CarDao getCardao() {
return cardao;
}
public void setCardao(CarDao cardao) {
this.cardao = cardao;
}
@Override
public String getSystemTime() throws Exception {
return cardao.getSystemTime();
}
}
CarServiceImpl kısmında @Service(“carService”) Buradaki carService ismi HelloBean sınıfından ManagedProperty olarak çağırılırken kullanılacak isimdir.
@Transactional(readOnly=true) Spring Transaction yönetimini ekliyoruz ben burada herhangi bir commit gerektirecek veritabanı işlemi yapmadığım için readOnly olarak yaptım. Eğer addUser() şeklinde bir metodumuz olsaydı hata anında ROLLBACK işlemi gerekseydi metodun başına @Transactional(rollbackFor = Exception.class, readOnly = false) şeklinde bir annotation eklemem gerekirdi.
@Autowired
