SSH整合

Struts Hibernate Bean Apache Spring

步骤1.新建web项目：SSH1.3

步骤2.首先整合Spring 和 Hibernate，将spring下的包和hibernate下的包导入进来，还有mysql的驱动类

步骤3.在类路径下新建beans.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"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
           http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd
           http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd
           http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd">
	<context:annotation-config/>
	<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
		<property name="driverClass" value="org.gjt.mm.mysql.Driver"/>
		<property name="jdbcUrl" value="jdbc:mysql://localhost:3306/itcast?useUnicode=true&amp;characterEncoding=UTF-8"/>
		<property name="user" value="root"/>
		<property name="password" value="root"/>
		<!--初始化时获取的连接数，取值应在minPoolSize与maxPoolSize之间。Default: 3 -->
		<property name="initialPoolSize" value="1"/>
		<!--连接池中保留的最小连接数。-->
		<property name="minPoolSize" value="1"/>	
		<!--连接池中保留的最大连接数。Default: 15 -->
		<property name="maxPoolSize" value="300"/>
		<!--最大空闲时间,60秒内未使用则连接被丢弃。若为0则永不丢弃。Default: 0 -->
		<property name="maxIdleTime" value="60"/>	
		<!--当连接池中的连接耗尽的时候c3p0一次同时获取的连接数。Default: 3 -->
		<property name="acquireIncrement" value="5"/>	
		<!--每60秒检查所有连接池中的空闲连接。Default: 0 -->
		<property name="idleConnectionTestPeriod" value="60"/>
	</bean>
	
	<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
	     <property name="dataSource" ref="dataSource"/>
	     <property name="mappingResources">
		    <list>
		      <value>cn/itcast/bean/Person.hbm.xml</value>
		    </list>
	     </property>
	     <property name="hibernateProperties">
		    <value>
		        hibernate.dialect=org.hibernate.dialect.MySQL5Dialect
		        hibernate.hbm2ddl.auto=update
		        hibernate.show_sql=false
		        hibernate.format_sql=false
		      </value>
	    </property>
	</bean>
	<bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
	  	<property name="sessionFactory" ref="sessionFactory"/>
	</bean>
	<tx:annotation-driven transaction-manager="txManager"/>
	<bean id="personService" class="cn.itcast.service.impl.PersonServiceBean"/>
	<bean name="/person/list" class="cn.itcast.web.action.PersonListAction"/>
	<bean name="/person/add" class="cn.itcast.web.action.PersonAddAction"/>
	<bean name="/person/updatebefore" class="cn.itcast.web.action.PersonUpdateBeforeAction"/>
	<bean name="/person/update" class="cn.itcast.web.action.PersonUpdateAction"/>
	<bean name="/person/delete" class="cn.itcast.web.action.PersonDeleteAction"/>
</beans>

步骤4.新建实体bean文件

package cn.itcast.bean;

public class Person {
	private Integer id;
	private String name;
	
	public Person(){}
	
	public Person(String name) {
		this.name = name;
	}
	public Integer getId() {
		return id;
	}
	public void setId(Integer id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	
	
}

其映射文件：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC
        "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
        "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping package="cn.itcast.bean">
    <class name="Person" table="person">
		<id name="id">
			<generator class="increment"/>
		</id>
		<property name="name" length="20" not-null="true"/>
    </class>
</hibernate-mapping>

步骤5.新建数据库操作类

package cn.itcast.service;

import java.util.List;

import cn.itcast.bean.Person;

public interface PersonService {

	public abstract void save(Person person);

	public abstract void update(Person person);

	public abstract Person find(Integer personid);

	public abstract List list();

	public abstract void delete(Integer personid);

}

其实现类：

package cn.itcast.service.impl;

import java.util.List;

import javax.annotation.Resource;

import org.hibernate.SessionFactory;
import org.springframework.transaction.annotation.Transactional;

import cn.itcast.bean.Person;
import cn.itcast.service.PersonService;

@Transactional
public class PersonServiceBean implements PersonService {
	@Resource
	SessionFactory sessionFactory;

	public void save(Person person) {
		sessionFactory.getCurrentSession().persist(person);
	}

	public void update(Person person) {
		sessionFactory.getCurrentSession().merge(person);
	}

	public Person find(Integer personid) {
		return (Person) sessionFactory.getCurrentSession().get(Person.class,
				personid);
	}

	public List list() {
		return sessionFactory.getCurrentSession().createQuery("from Person")
				.list();
	}

	public void delete(Integer personid) {
		sessionFactory.getCurrentSession()
				.delete(
						sessionFactory.getCurrentSession().load(Person.class,
								personid));
	}
}

步骤6.编写junit测试

package junit.test;


import java.util.List;

import org.junit.BeforeClass;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import cn.itcast.bean.Person;
import cn.itcast.service.PersonService;

public class PersonServiceTest {
	private static PersonService personService;
	@BeforeClass
	public static void setUpBeforeClass() throws Exception {
		try {
			ApplicationContext act = new ClassPathXmlApplicationContext("beans.xml");
			personService = (PersonService) act.getBean("personService");
		} catch (RuntimeException e) {
			e.printStackTrace();
		}
	}
	
	@Test
	public void testSave(){
		personService.save(new Person("老张"));
	}
	@Test
	public void testUpdate(){
		Person person = personService.find(1);
		person.setName("老李");
		personService.update(person);
	}	
	@Test
	public void testFind(){
		Person person = personService.find(1);
		System.out.println(person.getName());
	}	
	@SuppressWarnings("unchecked")
	@Test
	public void testList(){
		List<Person> list = personService.list();
		for(Person person : list){
			System.out.println(person.getName());
		}
	}	
	@Test
	public void testDelete(){
		personService.delete(1);
	}

}

测试正常，然后

步骤7.将struts1.3.8下的包导入进来

步骤8.在WEB-INF目录下新建struts-config.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.2//EN" "http://struts.apache.org/dtds/struts-config_1_2.dtd">

<struts-config>
  <form-beans>
  	<form-bean name="personForm" type="cn.itcast.form.PersonForm"/>
  </form-beans>
  <global-exceptions />
  <global-forwards />
  <action-mappings>
  	<action path="/person/list" type="cn.itcast.web.action.PersonListAction"
  	 validate="false">
  	 <forward name="list" path="/WEB-INF/page/personlist.jsp"/>
  	 </action>
  	 
  	<action path="/person/add" validate="false" name="personForm">
  	 <forward name="add" path="/person/list.do"/>
  	 </action>
  	 
  	<action path="/person/updatebefore" validate="false" name="personForm">
  	 <forward name="updatebefore" path="/WEB-INF/page/personupdate.jsp"/>
  	 </action>  
  	   	 
  	<action path="/person/update" validate="false" name="personForm">
  	 <forward name="update" path="/person/list.do"/>
  	 </action>  
  	 
  	<action path="/person/delete" validate="false" name="personForm">
  	 <forward name="delete" path="/person/list.do"/>
  	 </action>  	 
  </action-mappings>
  
	<controller>
	 <set-property property="processorClass" value="org.springframework.web.struts.DelegatingRequestProcessor"/>
	</controller> 
  
</struts-config>

步骤9.web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" 
	xmlns="http://java.sun.com/xml/ns/j2ee" 
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
	xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee 
	http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
	
	<!-- 指定spring的配置文件，默认从web根目录寻找配置文件，我们可以通过spring提供的classpath:前缀指定从类路径下寻找 -->
	<context-param>
	   <param-name>contextConfigLocation</param-name>
	   <param-value>classpath:beans.xml</param-value>
	</context-param>
	<!-- 对Spring容器进行实例化 -->
	<listener>
	      <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
	<!-- struts1.3.8的配置 -->
	<servlet>
		<servlet-name>struts</servlet-name>
		<servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
		<init-param>
			<param-name>config</param-name>
			<param-value>/WEB-INF/struts-config.xml</param-value>
		</init-param>
		<load-on-startup>0</load-on-startup>
	</servlet>
	<servlet-mapping>
		<servlet-name>struts</servlet-name>
		<url-pattern>*.do</url-pattern>
	</servlet-mapping>

  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
  
 <!-- 中文乱码 -->
<filter>
	<filter-name>encoding</filter-name>
	<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
	<init-param>

	</init-param>
</filter>
<filter-mapping>
	<filter-name>encoding</filter-name>
	<url-pattern>/*</url-pattern>
</filter-mapping>

</web-app>

步骤10.新建form

package cn.itcast.form;

import org.apache.struts.action.ActionForm;

public class PersonForm extends ActionForm {
	private static final long serialVersionUID = 1L;
	private String name;
	private Integer id;
	
	
	public Integer getId() {
		return id;
	}
	public void setId(Integer id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
}

步骤11.新建action类

添加方法：

package cn.itcast.web.action;

import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;

import cn.itcast.bean.Person;
import cn.itcast.form.PersonForm;
import cn.itcast.service.PersonService;

public class PersonAddAction extends Action {
	@Resource PersonService personService;
	@Override
	public ActionForward execute(ActionMapping mapping, ActionForm form,
			HttpServletRequest request, HttpServletResponse response) throws Exception {
		PersonForm personForm = (PersonForm) form;
		Person person = new Person();
		person.setName(personForm.getName());
		personService.save(person);
		return mapping.findForward("add");
	}

}

修改方法：

package cn.itcast.web.action;

import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.commons.beanutils.BeanUtils;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;

import cn.itcast.form.PersonForm;
import cn.itcast.service.PersonService;

public class PersonUpdateBeforeAction extends Action {
	@Resource PersonService personService;
	@Override
	public ActionForward execute(ActionMapping mapping, ActionForm form,
			HttpServletRequest request, HttpServletResponse response) throws Exception {
		PersonForm personForm = (PersonForm) form;
		Integer id = Integer.parseInt(request.getParameter("id"));
		//request.setAttribute("person", personService.find(id));
		
		BeanUtils.copyProperties(personForm, personService.find(id));
		return mapping.findForward("updatebefore");
	}

}

package cn.itcast.web.action;

import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.commons.beanutils.BeanUtils;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;

import cn.itcast.bean.Person;
import cn.itcast.form.PersonForm;
import cn.itcast.service.PersonService;

public class PersonUpdateAction extends Action {
	@Resource PersonService personService;
	@Override
	public ActionForward execute(ActionMapping mapping, ActionForm form,
			HttpServletRequest request, HttpServletResponse response) throws Exception {
		PersonForm personForm = (PersonForm) form;
		//Integer id = Integer.parseInt(request.getParameter("id"));
		Person person = new Person();
		//person.setId(id);
		//person.setName(personForm.getName());
		BeanUtils.copyProperties(person, personForm);
		personService.update(person);
		return mapping.findForward("update");
	}

}

删除方法：

package cn.itcast.web.action;

import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;

import cn.itcast.form.PersonForm;
import cn.itcast.service.PersonService;

public class PersonDeleteAction extends Action {
	@Resource PersonService personService;
	@Override
	public ActionForward execute(ActionMapping mapping, ActionForm form,
			HttpServletRequest request, HttpServletResponse response) throws Exception {
		PersonForm personForm = (PersonForm) form;
		//Integer id = Integer.parseInt(request.getParameter("id"));
		personService.delete(personForm.getId());
		return mapping.findForward("delete");
	}
}

查询所有方法：

package cn.itcast.web.action;

import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;

import cn.itcast.service.PersonService;

public class PersonListAction extends Action {
	@Resource PersonService personService;
	@Override
	public ActionForward execute(ActionMapping mapping, ActionForm form,
			HttpServletRequest request, HttpServletResponse response) throws Exception {
		/*
		WebApplicationContext ctx = WebApplicationContextUtils
				.getWebApplicationContext(this.getServlet().getServletContext());
		PersonService personService = (PersonService) ctx.getBean("personService");
		*/
		request.setAttribute("persons", personService.list());
		return mapping.findForward("list");
	}

}

步骤12.新建jsp文件

在WebRoot下新建index.jsp文件（插入页面）

<%@ page language="java" pageEncoding="UTF-8"%>
<%@ taglib prefix="html" uri="http://struts.apache.org/tags-html"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    <title>添加</title>
	<meta http-equiv="pragma" content="no-cache">
	<meta http-equiv="cache-control" content="no-cache">
	<meta http-equiv="expires" content="0">
  </head>
  
  <body>
    <html:form action="/person/add">
		姓名：<html:text property="name"/><br/>
		<input type="submit" value="提交"/>
    </html:form>
  </body>
</html>

在WEB-INF目录下新建page文件夹，在page下新建

personlist.jsp

<%@ page language="java" pageEncoding="UTF-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    <title>人员列表</title>
    
	<meta http-equiv="pragma" content="no-cache">
	<meta http-equiv="cache-control" content="no-cache">
	<meta http-equiv="expires" content="0">

  </head>
  
  <body>
    <c:forEach items="${persons}" var="person">
    	ID=${person.id },name=${person.name }<a href="/SSH1.3/person/updatebefore.do?id=${person.id }">修改</a>
    	<a href="/SSH1.3/person/delete.do?id=${person.id }">删除</a> <br/>
    </c:forEach>
  </body>
</html>

personupdate.jsp

<%@ page language="java" pageEncoding="UTF-8"%>
<%@ taglib prefix="html" uri="http://struts.apache.org/tags-html"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    <title>修改页面</title>
    
	<meta http-equiv="pragma" content="no-cache">
	<meta http-equiv="cache-control" content="no-cache">
	<meta http-equiv="expires" content="0">    
  </head>
  
  <body>
	<html:form action="/person/update">
		<%--<input type="hidden" name="id" value="${person.id }"/>
		<input type="text" name="name" value="${person.name }"/>
		--%>
		<html:hidden property="id"/>
		<html:text property="name"/>
		<input type="submit" value="submit"/>
	</html:form>
  </body>
</html>

OK，调试运行即可！！！
