Spring 框架入门教程-60. Spring JDF Hibernate-55编程教程网

欢迎来到Jsf Spring Hibernate集成示例教程。在上一个教程中，我们看到了如何集成JSF和Spring框架在一起。今天我们将学习如何整合JSF Spring Hibernate框架。在用户界面、服务器端依赖注入和ORM工具方面，这是一个很好的组合。

1JSF Spring Hibernate

JSF Spring Hibernate

我们的目标是创建一个单页用户界面，从中我们可以输入一些进入数据库的数据。我们得到了相同的响应页面，其中还显示了表中的数据，因此新添加的数据也应该在submit页面上。

下图显示了我们最终的Spring Jsf-hibernate集成项目结构。现在让我们从这个项目开始，看看每个框架是如何粘合在一起以实现我们的目标的。

JSF Spring Hibernate项目设置

在Eclipse中创建一个动态Web项目，然后将其转换为Maven项目，这样我们就可以准备好基本的设置了。现在我们必须在pom.xml文件文件。下面是我们的决赛pom.xml文件文件。注意JSF、Spring、Spring Orm和Hibernate依赖项。我们使用MySQL数据库作为示例，apachedbcp用于创建简单的数据库连接池。

现在使用下面的脚本在数据库中创建所需的表。


CREATE TABLE `Person` (
  `id` int(11) unsigned NOT NULL AUTO_INCREMENT,
  `name` varchar(20) NOT NULL DEFAULT "",
  `country` varchar(20) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;

接下来我们需要在web.xml文件文件如下所示。


<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.1" xmlns="https://xmlns.jcp.org/xml/ns/javaee" 
xmlns:xsi="https://www.w3.org/2001/XMLSchema-instance" 
xsi:schemaLocation="https://xmlns.jcp.org/xml/ns/javaee 
https://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd">
    
  <listener>
	<listener-class>
		org.springframework.web.context.ContextLoaderListener
	</listener-class>
  </listener>
  <listener>
	<listener-class>
		org.springframework.web.context.request.RequestContextListener
	</listener-class>
  </listener>
    
    <context-param>
        <param-name>javax.faces.PROJECT_STAGE</param-name>
        <param-value>Development</param-value>
    </context-param>
    <servlet>
        <servlet-name>Faces Servlet</servlet-name>
        <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>Faces Servlet</servlet-name>
        <url-pattern>/*</url-pattern>
    </servlet-mapping>
    <session-config>
        <session-timeout>
            30
        </session-timeout>
    </session-config>
    
</web-app>

接下来我们需要JSF与Spring框架集成，为此我们需要配置SpringBeanFacesELResolver in faces-config.xml file. It will make sure that JSF view pages variables are mapped to the backend managed beans.

faces-config.xml


<?xml version="1.0" encoding="UTF-8"?>
<faces-config version="2.2"
              xmlns="https://xmlns.jcp.org/xml/ns/javaee"
              xmlns:xsi="https://www.w3.org/2001/XMLSchema-instance"
              xsi:schemaLocation="https://xmlns.jcp.org/xml/ns/javaee 
              https://xmlns.jcp.org/xml/ns/javaee/web-facesconfig_2_2.xsd">

    <application>
        <el-resolver>
            org.springframework.web.jsf.el.SpringBeanFacesELResolver
        </el-resolver>
    </application>
    
</faces-config>

我们需要的最后一个配置是Spring Beans配置，但是我们将在看过java类之后再看一下。

JSF-Spring-Hibernate模型类

我们有Person.java class that is mapped with the Person table in database. Notice the use of JPA and JSF annotations.


package com.journaldev.springhibernate.model;

import javax.faces.bean.ManagedBean;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
 
/**
 * Entity bean with JPA annotations
 * Hibernate provides JPA implementation
 * @author pankaj
 *
 */
@Entity
@Table(name="PERSON")
@ManagedBean(name="person")
public class Person {
	@Id
    @Column(name="id")
    @GeneratedValue(strategy=GenerationType.IDENTITY)
    private int id;
     
    private String name;
     
    private String country;
 
    public int getId() {
        return id;
    }
 
    public void setId(int id) {
        this.id = id;
    }
 
    public String getName() {
        return name;
    }
 
    public void setName(String name) {
        this.name = name;
    }
 
    public String getCountry() {
        return country;
    }
 
    public void setCountry(String country) {
        this.country = country;
    }
     
    @Override
    public String toString(){
        return "id="+id+", name="+name+", country="+country;
    }
}

现在我们将转到创建DAO类来与数据库表交互。

JSF Spring Hibernate DAO类

PersonDAO.java


package com.journaldev.springhibernate.dao;

import java.util.List;

import com.journaldev.springhibernate.model.Person;
 
public interface PersonDAO {
 
    public void addPerson(Person p);
    public List<Person> listPersons();
}

我们有两种方法，一种是在数据库表中插入数据，另一种是获取用户界面中显示的人员列表。

下面是上述DAO的实现类。

PersonDAOImpl.java


package com.journaldev.springhibernate.dao;

import java.util.List;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Repository;

import com.journaldev.springhibernate.model.Person;

@Repository
public class PersonDAOImpl implements PersonDAO{
	
	private static final Logger logger = LoggerFactory.getLogger(PersonDAOImpl.class);
	 
    private SessionFactory sessionFactory;
     
    public void setSessionFactory(SessionFactory sf){
        this.sessionFactory = sf;
    }
 
    @Override
    public void addPerson(Person p) {
        Session session = this.sessionFactory.getCurrentSession();
        session.persist(p);
        logger.info("Person saved successfully, Person Details="+p);
    }
 
    @SuppressWarnings("unchecked")
    @Override
    public List<Person> listPersons() {
        Session session = this.sessionFactory.getCurrentSession();
        List<Person> personsList = session.createQuery("from Person").list();
        for(Person p : personsList){
            logger.info("Person List::"+p);
        }
        return personsList;
    }
 
}

现在我们将创建服务类，然后进行连接。

JSF Spring Hibernate服务类

PersonService.java


package com.journaldev.springhibernate.service;

import java.util.List;

import com.journaldev.springhibernate.model.Person;
 
public interface PersonService {
 
    public void addPerson(Person p);
    public List<Person> listPersons();
     
}

PersonServiceImpl.java


package com.journaldev.springhibernate.service;

import java.util.List;

import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;

import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import com.journaldev.springhibernate.dao.PersonDAO;
import com.journaldev.springhibernate.model.Person;

@Service
@ManagedBean(name="personService")
@SessionScoped
public class PersonServiceImpl implements PersonService {

	private PersonDAO personDAO;
	 
    public void setPersonDAO(PersonDAO personDAO) {
        this.personDAO = personDAO;
    }
 
    @Override
    @Transactional
    public void addPerson(Person p) {
        this.personDAO.addPerson(p);
    }
 
    @Override
    @Transactional
    public List<Person> listPersons() {
        return this.personDAO.listPersons();
    }
 
}

注意使用@ManagedBean JSF annotation and @Transactional annotation for transaction management.

Spring Beans配置文件

我们基于springhibernate的后端服务已经准备好了，现在我们可以将它们连接到Spring Beans配置文件中，如下所示。

applicationContext.xml


<?xml version="1.0" encoding="UTF-8"?>
<beans:beans xmlns="https://www.springframework.org/schema/mvc"
	xmlns:xsi="https://www.w3.org/2001/XMLSchema-instance" xmlns:beans="https://www.springframework.org/schema/beans"
	xmlns:context="https://www.springframework.org/schema/context" xmlns:tx="https://www.springframework.org/schema/tx"
	xsi:schemaLocation="https://www.springframework.org/schema/mvc https://www.springframework.org/schema/mvc/spring-mvc.xsd
        https://www.springframework.org/schema/beans https://www.springframework.org/schema/beans/spring-beans.xsd
        https://www.springframework.org/schema/context https://www.springframework.org/schema/context/spring-context.xsd
        https://www.springframework.org/schema/tx https://www.springframework.org/schema/tx/spring-tx-4.0.xsd">

	<!-- DispatcherServlet Context: defines this servlet"s request-processing 
		infrastructure -->

	<!-- Enables the Spring MVC @Controller programming model -->
	<annotation-driven />

		up static resources in the ${webappRoot}/resources directory -->
	<resources mapping="/resources/**" location="/resources/" />


	<beans:bean id="dataSource"
		destroy-method="close">
		<beans:property name="driverClassName" value="com.mysql.jdbc.Driver" />
		<beans:property name="url"
			value="jdbc:mysql://localhost:3306/TestDB" />
		<beans:property name="username" value="pankaj" />
		<beans:property name="password" value="pankaj123" />
	</beans:bean>

	<!-- Hibernate 4 SessionFactory Bean definition -->
	<beans:bean id="hibernate4AnnotatedSessionFactory"
	>
		<beans:property name="dataSource" ref="dataSource" />
		<beans:property name="annotatedClasses">
			<beans:list>
				<beans:value>com.journaldev.springhibernate.model.Person</beans:value>
			</beans:list>
		</beans:property>
		<beans:property name="hibernateProperties">
			<beans:props>
				<beans:prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect
				</beans:prop>
				<beans:prop key="hibernate.show_sql">true</beans:prop>
			</beans:props>
		</beans:property>
	</beans:bean>

	<beans:bean id="personDAO"
	>
		<beans:property name="sessionFactory"
			ref="hibernate4AnnotatedSessionFactory" />
	</beans:bean>
	<beans:bean id="personService"
	>
		<beans:property name="personDAO" ref="personDAO"></beans:property>
	</beans:bean>
	
	<context:component-scan base-package="com.journaldev" />

	<tx:annotation-driven transaction-manager="transactionManager" />

	<beans:bean id="transactionManager"
	>
		<beans:property name="sessionFactory"
			ref="hibernate4AnnotatedSessionFactory" />
	</beans:bean>

</beans:beans>

注意数据源配置，你必须根据你的设置来调整它们。

JSF视图页面

最后一部分是编写JSF视图页面并使用上面配置的托管bean。

person.xhtml


<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"

			<tr>
				<td colspan="2"><h:commandButton

		</table>

	</h:form>

	<br>
	<h3>Persons List</h3>
	

	<c:if test="${!empty personService.listPersons()}">
		<table>
			<tr>
				<th width="80">Person ID</th>
				<th width="120">Person Name</th>

					<td>${person.name}</td>
					<td>${person.country}</td>
				</tr>
			</ui:repeat>
		</table>
	</c:if>

</h:body>
</html>

就这样，现在只需将应用程序部署到您最喜欢的servlet容器中并运行它，您应该会看到下面的页面。
