JSF2.0+Spring+Hibernate整合示例-优快云博客

JSF 2.0 + Spring + Hibernate 整合例子

Here’s a long article to show you how to integrate JSF 2.0, Spring and Hibernate together. At the end of the article, you will create a page which display a list of the existing customer from database and a “add customer” function to allow user to add a new customer into database.

P.S In this example, we are using MySQL database and deploy to Tomcat 6 web container.

在这里，将用Jsf2.0,Spring 以及Hibernate 进行整合，文章最后，项目将会创建

1. Project Structure

Directory structure of this example

2. Table Script

Create a customer table and insert 2 dummy records.

DROP TABLE IF EXISTS `mkyongdb`.`customer`;
CREATE TABLE  `mkyongdb`.`customer` (
  `CUSTOMER_ID` BIGINT(20) UNSIGNED NOT NULL AUTO_INCREMENT,
  `NAME` VARCHAR(45) NOT NULL,
  `ADDRESS` VARCHAR(255) NOT NULL,
  `CREATED_DATE` datetime NOT NULL,
  PRIMARY KEY (`CUSTOMER_ID`)
) ENGINE=InnoDB AUTO_INCREMENT=17 DEFAULT CHARSET=utf8;
 
INSERT INTO mkyongdb.customer(customer_id, name, address, created_date)
VALUES(1, 'mkyong1', 'address1', now());
INSERT INTO mkyongdb.customer(customer_id, name, address, created_date)
VALUES(2, 'mkyong2', 'address2', now());

3. Hibernate Stuff

A model class and Hibernate mapping file for customer table.

File : Customer.java

package com.mkyong.customer.model;
 
import java.util.Date;
 
public class Customer{
 
	public long customerId;
	public String name;
	public String address;
	public Date createdDate;
 
	//getter and setter methods
 
}

File : Customer.hbm.xml

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC 
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
    <class name="com.mkyong.customer.model.Customer" 
        table="customer" catalog="mkyongdb">
 
        <id name="customerId" type="long">
            <column name="CUSTOMER_ID" />
            <generator class="identity" />
        </id>
        <property name="name" type="string">
            <column name="NAME" length="45" not-null="true" />
        </property>
        <property name="address" type="string">
            <column name="ADDRESS" not-null="true" />
        </property>
        <property name="createdDate" type="timestamp">
            <column name="CREATED_DATE" length="19" not-null="true" />
        </property>
    </class>
</hibernate-mapping>

4. Spring Stuff

Spring’s BO and DAO classes for business logic and database interaction.

File : CustomerBo.java

package com.mkyong.customer.bo;
 
import java.util.List;
 
import com.mkyong.customer.model.Customer;
 
public interface CustomerBo{
 
	void addCustomer(Customer customer);
 
	List<Customer> findAllCustomer();
 
}

File : CustomerBoImpl.java

package com.mkyong.customer.bo.impl;
 
import java.util.List;
import com.mkyong.customer.bo.CustomerBo;
import com.mkyong.customer.dao.CustomerDao;
import com.mkyong.customer.model.Customer;
 
public class CustomerBoImpl implements CustomerBo{
 
	CustomerDao customerDao;
 
	public void setCustomerDao(CustomerDao customerDao) {
		this.customerDao = customerDao;
	}
 
	public void addCustomer(Customer customer){
 
		customerDao.addCustomer(customer);
 
	}
 
	public List<Customer> findAllCustomer(){
 
		return customerDao.findAllCustomer();
	}
}

File : CustomerDao.java

package com.mkyong.customer.dao;
 
import java.util.List;
 
import com.mkyong.customer.model.Customer;
 
public interface CustomerDao{
 
	void addCustomer(Customer customer);
 
	List<Customer> findAllCustomer();
 
}

File : CustomerDaoImpl.java

package com.mkyong.customer.dao.impl;
 
import java.util.Date;
import java.util.List;
 
import com.mkyong.customer.dao.CustomerDao;
import com.mkyong.customer.model.Customer;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
 
public class CustomerDaoImpl extends 
       HibernateDaoSupport implements CustomerDao{
 
	public void addCustomer(Customer customer){
 
		customer.setCreatedDate(new Date());
		getHibernateTemplate().save(customer);
 
	}
 
	public List<Customer> findAllCustomer(){
 
		return getHibernateTemplate().find("from Customer");
 
	}
}

File : CustomerBean.xml

<?xml version="1.0" encoding="UTF-8"?>
<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-2.5.xsd">
 
   	<bean id="customerBo" 
         class="com.mkyong.customer.bo.impl.CustomerBoImpl" >
   		<property name="customerDao" ref="customerDao" />
   	</bean>
 
   	<bean id="customerDao" 
         class="com.mkyong.customer.dao.impl.CustomerDaoImpl" >
   		<property name="sessionFactory" ref="sessionFactory" />
   	</bean>
 
</beans>

5. Spring + Database

Configure database detail in Spring.

File : db.properties

jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/mkyongdb
jdbc.username=root
jdbc.password=password

File : DataSource.xml

<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-2.5.xsd">
 
 <bean 
   class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
   <property name="location">
		<value>WEB-INF/classes/config/database/db.properties</value>
   </property>
</bean>
 
  <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
	<property name="driverClassName" value="${jdbc.driverClassName}" />
	<property name="url" value="${jdbc.url}" />
	<property name="username" value="${jdbc.username}" />
	<property name="password" value="${jdbc.password}" />
  </bean>
 
</beans>

6. Spring + Hibernate

Integrate Hibernate and Spring via LocalSessionFactoryBean.

File : HibernateSessionFactory.xml

<?xml version="1.0" encoding="UTF-8"?>
<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-2.5.xsd">
 
<!-- Hibernate session factory -->
<bean id="sessionFactory" 
     class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
 
    <property name="dataSource">
      <ref bean="dataSource"/>
    </property>
 
    <property name="hibernateProperties">
       <props>
         <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
         <prop key="hibernate.show_sql">true</prop>
       </props>
    </property>
 
    <property name="mappingResources">
	<list>
          <value>com/mkyong/customer/hibernate/Customer.hbm.xml</value>
	</list>
     </property>	
 
</bean>
</beans>

7. JSF 2.0

JSF managed bean to call Spring’s BO to add or get customer’s records from database.

File : CustomerBean.java

package com.mkyong;
 
import java.io.Serializable;
import java.util.List;
 
import com.mkyong.customer.bo.CustomerBo;
import com.mkyong.customer.model.Customer;
 
public class CustomerBean implements Serializable{
 
	//DI via Spring
	CustomerBo customerBo;
 
	public String name;
	public String address;
	//getter and setter methods
 
	public void setCustomerBo(CustomerBo customerBo) {
		this.customerBo = customerBo;
	}
 
	//get all customer data from database
	public List<Customer> getCustomerList(){
		return customerBo.findAllCustomer();
	}
 
	//add a new customer data into database
	public String addCustomer(){
 
		Customer cust = new Customer();
		cust.setName(getName());
		cust.setAddress(getAddress());
 
		customerBo.addCustomer(cust);
 
		clearForm();
 
		return "";
	}
 
	//clear form values
	private void clearForm(){
		setName("");
		setAddress("");
	}
 
}

A JSF page to display existing customer records via h:dataTable and a few text components to allow user to insert new customer record into database.

 		</h:form>
 
    </h:body>
 
</html>
