This blog is mainly for the beginners who wants to setup JSF 2.0, Primefaces 3.3, Spring 3.1 and Hibernate 4.0 environment in eclipse.
Frameworks and versions used in this sample project.
Java - 1.6.0
JSF 2.0 - Mojarra 2.1.5 implementation
Primefaces - 3.3.1
Spring - 3.1
Hibernate - 4.0
Application Server - JBoss 7.1
ojdbc5.jar - to connect to Oracle database
mysql-connector-java-5.1.3-rc-bin.jar - to connect to MySQL.
The sample project which I am going to demonstrate will fetch all the records from the Employee table and displays them in a primefaces table.
Step1
Create a test database in MySQL or Oracle. The following script is to create a table named Employee in MySQL test database.
CREATE TABLE `employee` (
`EmpID` int(11) NOT NULL,
`EmpName` varchar(200) DEFAULT NULL,
`Email` varchar(300) DEFAULT NULL,
PRIMARY KEY (`EmpID`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8$$
Step2
Create the Employee entity class i.e Employee.java
package com.springHibernate.model;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;
@Entity
@Table(name="Employee")
public class Employee {
@Id
@Column(name="EmpID")
private int empID;
@Column(name="EmpName")
private String empName;
@Column(name="Email")
private String email;
public int getEmpID() {
return empID;
}
public void setEmpID(int empID) {
this.empID = empID;
}
public String getEmpName() {
return empName;
}
public void setEmpName(String empName) {
this.empName = empName;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
}
Step 3
Implementing Dao(Data access object) layer.
EmpDao.java
package com.springHibernate.dao;
import java.util.List;
import com.springHibernate.model.Employee;
public interface EmpDao {
public List
getAllEmployees();
}
EmpDaoImpl.java
package com.springHibernate.dao;
import java.util.List;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
import com.springHibernate.model.Employee;
@Repository("empDaoImpl")
public class EmpDaoImpl implements EmpDao{
@Autowired
private SessionFactory sessionFactory;
public SessionFactory getSessionFactory() {
return sessionFactory;
}
public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}
@SuppressWarnings("unchecked")
@Override
public List
getAllEmployees() {
return sessionFactory.getCurrentSession().createQuery("from Employee").list();
}
}
Step 4
Implementing Service layer.
EmpService.java
package com.springHibernate.service;
import java.util.List;
import com.springHibernate.model.Employee;
public interface EmpService {
public List
getAllEmployees();
}
EmpServiceImpl.java
package com.springHibernate.service;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import com.springHibernate.dao.EmpDao;
import com.springHibernate.model.Employee;
@Service("empServiceImpl")
public class EmpServiceImpl implements EmpService {
@Autowired
EmpDao empDao;
public EmpDao getEmpDao() {
return empDao;
}
public void setEmpDao(EmpDao empDao) {
this.empDao = empDao;
}
@Transactional(readOnly = true)
public List getAllEmployees() {
return empDao.getAllEmployees();
}
}
Step 5
Implementing view layer. which involves creating index.xhtml and corresponding JSF managedBean.
index.xhtml
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html" xmlns:f="http://java.sun.com/jsf/core" xmlns:p="http://primefaces.org/ui">
<h:head>
<link type="text/css" rel="stylesheet" href="themes/bluesky/skin.css" />
<style type="text/css"> .ui-panel { font-size: 85% !important; font-family: calibri !important; align: "center" !important; } </style>
</h:head>
<h:body>
<p:panel header="ASSET 3000" style="width: 350;">
<h:form prependId="false">
<p:dataTable id="basic" var="emp" value="#{employeeBean.empList}">
<p:column id="nameHeader">
<f:facet name="header"> Employee Name </f:facet>
<h:outputText value="#{emp.empName}" />
</p:column>
<p:column>
<f:facet name="header"> Emp Number </f:facet>
<h:outputText value="#{emp.empID}" />
</p:column>
<p:column>
<f:facet name="header"> Email </f:facet>
<h:outputText value="#{emp.email}" />
</p:column>
</p:dataTable>
</h:form>
</p:panel>
</h:body>
</html>
EmployeeBean.java -- JSF managedBean.
package com.springHibernate.managedBeans;
import java.util.ArrayList;
import java.util.List;
import javax.faces.bean.ManagedProperty;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Component;
import com.springHibernate.model.Employee;
import com.springHibernate.service.EmpService;
@Component
@Scope("request")
public class EmployeeBean {
@Autowired
EmpService empService;
private List
empList;
private int empID;
private String empName;
private String email;
public EmpService getEmpService() {
return empService;
}
public void setEmpService(EmpService empService) {
this.empService = empService;
}
public List
getEmpList() {
empList = new ArrayList
();
empList.addAll(getEmpService().getAllEmployees());
return empList;
}
public void setEmpList(List
empList) {
this.empList = empList;
}
public int getEmpID() {
return empID;
}
public void setEmpID(int empID) {
this.empID = empID;
}
public String getEmpName() {
return empName;
}
public void setEmpName(String empName) {
this.empName = empName;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
}
Step 6
Finally, the configuration files.
