java Spring-3.2.0+Struts-2.3.4+Hibernate-4.1.6整合

    博客分类:
  • J2EE
阅读更多

我的前一篇博文讲了Spring-3.2.0+Struts2.3.4+JPA2.0整合,其所需的jar包与Spring-3.2.0 +Struts-2.3.4+Hibernate-4.1.6所需的jar包基本相同.下面列出SSH整合所需要的jar包.


 

 如上图所示是Spring-3.2.0 +Struts-2.3.4+Hibernate-4.1.6的jar包,这些jar包在各官网上都有提供下载:

Spring的jar包下载地址:http://www.springsource.org/spring-community-download(需要填写一些信息)

Hibernate的jar包下载地址:http://www.hibernate.org/downloads.html

Struts的jar包下载地址:http://struts.apache.org/download.cgi

 

注意在jar包整合,由于spring的jar已经相应独立开,还有其它jar也不同,所以要注意相关jar包的版本,不要以为包引多了没关系,jar冲突和版本不同也会导致整合失败.另外用MyEclipse(Eclipse)新建项目时会自动引入J2EE相关的jar包,建议删除,手动引入.

 

 

下面使用MySQL做演示:

首先我们在(src)下新建jdbc.properties文件用来配置数据库基本信息,其内容如下:

 

jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://127.0.0.1:3306/shopping
jdbc.username=root
jdbc.password=619100

 

 

然后我们新建Spring配置文件beans.xml,将其放入在classpath(src)下,其内容如下:

 

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:aop="http://www.springframework.org/schema/aop"
	xmlns:tx="http://www.springframework.org/schema/tx"
	xsi:schemaLocation="http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
           http://www.springframework.org/schema/context

           http://www.springframework.org/schema/aop
           http://www.springframework.org/schema/aop/spring-aop-3.2.xsd
           http://www.springframework.org/schema/tx
           http://www.springframework.org/schema/tx/spring-tx-3.2.xsd">
	
	<context:annotation-config/>
	<!-- 声明Spring要管理的范围 -->
	<context:component-scan base-package="gd.hz.shopping" />
	
	<!-- 读取jdbc.properties配置文件 -->
	<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
		<property name="locations">
			<value>classpath:jdbc.properties</value>
		</property>
	</bean>
	<bean id="dataSource" destroy-method="close"
		class="org.apache.commons.dbcp.BasicDataSource">
		<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>

	<!-- 创建sessionFactory -->
	<bean id="sessionFactory"
		class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
		<property name="dataSource" ref="dataSource" />
		<property name="packagesToScan">
			<list>
				<!-- 需要映射的实体类,指定到实体类所在的包即可 -->
				<value>gd.hz.shopping.model</value>
			</list>
		</property>
		<property name="hibernateProperties">
			<props>
				<prop key="hibernate.format_sql">true</prop>
	        
		        <prop key="dialect">org.hibernate.dialect.MySQLDialect</prop>
		      	
		        <prop key="hibernate.show_sql">true</prop>
		      	
		        <prop key="current_session_context_class">thread</prop>
		      	
		        <prop key="connection.pool_size">3</prop>

		        <prop key="javax.persistence.validation.mode">none</prop>
		        
		        <prop key="hibernate.current_session_context_class">org.springframework.orm.hibernate4.SpringSessionContext</prop>
			</props>
		</property>
	</bean>
	
	<!-- 开启事务管理 -->
	<bean id="txManager"
		class="org.springframework.orm.hibernate4.HibernateTransactionManager">
		<property name="sessionFactory" ref="sessionFactory" />
	</bean>
	<aop:config>
		<aop:pointcut id="bussinessService"
			expression="execution(public * gd.hz.shopping.service.*.*(..))" />
		<aop:advisor pointcut-ref="bussinessService"
			advice-ref="txAdvice" />
	</aop:config>
	
	<!-- 使用声明式事务 -->
	<tx:advice id="txAdvice" transaction-manager="txManager">
		<tx:attributes>
			<tx:method name="find*" read-only="true" propagation="REQUIRED" />
			<tx:method name="save*" propagation="REQUIRED"/>
			<tx:method name="modify*" propagation="REQUIRED"/>
			<tx:method name="remove*" propagation="REQUIRED"/>
		</tx:attributes>
	</tx:advice>
	 
</beans>

 

 

 

新建我们的struts配置文件struts.xml,内容如下:

 

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN" "http://struts.apache.org/dtds/struts-2.3.dtd">

<struts>
	<constant name="struts.devMode" value="true" />
	<constant name="struts.i18n.encoding" value="UTF-8" />
</struts>
	

 

 

 

然后配置我们的web.xml文件:

 

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
	http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">

	<!-- 加载Spring配置文件 -->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:beans.xml</param-value>
	</context-param>
	
	<!-- ContextLoaderListener的作用就是启动Web容器时,自动装配ApplicationContext的配置信息。 -->
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>

	<!-- 指定字符集 -->
	<filter>
		<filter-name>encodingFilter</filter-name>
		<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
		<init-param>
			<param-name>encoding</param-name>
			<param-value>UTF-8</param-value>
		</init-param>
	</filter>
	<filter-mapping>
		<filter-name>encodingFilter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>

	<!-- 保持session到页面 -->
	<filter>
		<filter-name>openSessionInView</filter-name>
		<filter-class>org.springframework.orm.hibernate4.support.OpenSessionInViewFilter</filter-class>
		<init-param>
			<param-name>sessionFactoryBeanName</param-name>
			<param-value>sessionFactory</param-value>
		</init-param>
	</filter>
	<filter-mapping>
		<filter-name>openSessionInView</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>

	<!-- 声明struts管理请求 -->
	<filter>
		<filter-name>struts2</filter-name>
		<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
	</filter>
	<filter-mapping>
		<filter-name>struts2</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>

</web-app>

 

 

 

最后我们做一个示例:

新建实体类:

 

package gd.hz.shopping.model;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;

@Entity
public class ProductType {
	private int productId ;
	
	private String name ;

	@Id
	@GeneratedValue(strategy=GenerationType.AUTO)
	public int getProductId() {
		return productId;
	}
	public void setProductId(int productId) {
		this.productId = productId ;
	}
	
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
}

 

 

 

新建Dao接口:

 

package gd.hz.shopping.dao;

import gd.hz.shopping.model.ProductType;

public interface ProductTypeDao {
	
	public ProductType selProductType(int id);
}

 

 

实现Dao接口:

 

package gd.hz.shopping.dao.impl;

import javax.annotation.Resource;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.stereotype.Component;

import gd.hz.shopping.dao.ProductTypeDao;
import gd.hz.shopping.model.ProductType;

@Component("productTypeDao")
public class ProductTypeDaoImpl implements ProductTypeDao {
	
	private SessionFactory sessionFactory = null ;
	
	@Resource(name="sessionFactory")
	public void setSessionFactory(SessionFactory sessionFactory) {
		this.sessionFactory = sessionFactory;
	}

	@Override
	public ProductType selProductType(int id) {
		Session session = sessionFactory.getCurrentSession() ;
		ProductType productType = (ProductType)session.get(ProductType.class , id);
		return productType ;
	}
}

 

 

Manager层接口:

 

package gd.hz.shopping.service;

import gd.hz.shopping.model.ProductType;

public interface ProductTypeMnager {
	public ProductType findProductType(int id) ;
}

 

 

 

Manager层接口实现:

 

package gd.hz.shopping.service.impl;

import javax.annotation.Resource;

import org.springframework.stereotype.Component;

import gd.hz.shopping.dao.ProductTypeDao;
import gd.hz.shopping.model.ProductType;
import gd.hz.shopping.service.ProductTypeMnager;

@Component("productTypeMnager")
public class ProductTypeMnagerImpl implements ProductTypeMnager {

	private ProductTypeDao productTypeDao = null ;
	
	@Resource(name="productTypeDao")
	public void setProductTypeDao(ProductTypeDao productTypeDao) {
		this.productTypeDao = productTypeDao;
	}

	@Override
	public ProductType findProductType(int id) {
		return productTypeDao.selProductType(id) ;
	}

}

 

 

 

 

 新建控制类ProductTypeAction:

 

package gd.hz.shopping.action;

import javax.annotation.Resource;

import gd.hz.shopping.model.ProductType;
import gd.hz.shopping.service.ProductTypeMnager;

import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Component;

import com.opensymphony.xwork2.ActionSupport;

@Component("productTypeAction")
@Scope("prototype")
public class ProductTypeAction extends ActionSupport {
	
	private static final long serialVersionUID = 1L;
	
	private ProductTypeMnager productTypeMnager = null ;
	private ProductType productType = null ;
	
	@Resource(name="productTypeMnager")
	public void setProductTypeMnager(ProductTypeMnager productTypeMnager) {
		this.productTypeMnager = productTypeMnager;
	}
	
	public ProductType getProductType() {
		return productType;
	}
	public void setProductType(ProductType productType) {
		this.productType = productType;
	}
	
	public String test()
	{
		productType = productTypeMnager.findProductType(1) ;
		return "test" ;
	}
}

 

 

 

 

配置struts.xml文件:

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN" "http://struts.apache.org/dtds/struts-2.3.dtd">

<struts>
	<constant name="struts.devMode" value="true" />
	<constant name="struts.i18n.encoding" value="UTF-8" />
	
	<package name="productType" namespace="/" extends="OA_default">
		<action name="productTypeAction" class="productTypeAction">
			<result name="test">/org/add_input.jsp</result>
		</action>
	</package>
</struts>
	

 

启动服务器,然后手动插入测试数据:

insert into ProductType(name) values('lfd');



 

 

新建jsp页面:

引入jstl 标签:<%@ taglib prefix="s"  uri="/struts-tags" %>

 

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<%@ taglib prefix="s"  uri="/struts-tags" %> 
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>ssh整合测试</title>
</head>
<body>
  <%--使用OGNL表达式--%>  
   Hello:<s:property value="productType.name"/><br> 
</body>
</html>
