1.用到的jar包学习笔记-----------------struts2 hibernate3 spring2.5整合

2.现将hibernate和spring整合测试

src目录下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: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-2.5.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-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/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd"> <context:annotation-config/> <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> <property name="driverClassName" value="org.gjt.mm.mysql.Driver"/> <property name="url" value="jdbc:mysql://localhost:3307/gjl?useUnicode=true&characterEncoding=UTF-8"/> <property name="username" value="root"/> <property name="password" value="wodemima"/>  <property name="initialSize" value="1"/>  <property name="maxActive" value="500"/>  <property name="maxIdle" value="2"/>  <property name="minIdle" value="1"/> </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 hibernate.cache.use_second_level_cache=true hibernate.cache.use_query_cache=false hibernate.cache.provider_class=org.hibernate.cache.EhCacheProvider </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 id="personList" class="cn.itcast.web.PersonAction"/></beans>

3.web.xml 这个web.xml是把struts2内容也集成进来了，如果不用可把struts部分删掉，里面还有hibernate内容OpenSessionInViewFilter不做解释，自己查吧。暂时没有用到可以删掉。这里我就不删了，后面集成struts要用到，先放在这里。

<?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"> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:beans.xml</param-value></context-param><listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener> <filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping><filter> <filter-name>OpenSessionInViewFilter</filter-name> <filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class></filter><filter-mapping> <filter-name>OpenSessionInViewFilter</filter-name> <url-pattern>/*</url-pattern></filter-mapping> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list></web-app>

4.准备数据

4.1 Person.java

package cn.itcast.bean;public class Person {private Integer id;private String name;public Person() { super(); } 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;}}

4.2 Person.hbm.xml 它和Person.java在同目录下

<?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"> <cache usage="read-write" region="cn.itcast.bean.Person"/> <id name="id"> <generator class="native"/> </id> <property name="name" length="10" not-null="true"/> </class></hibernate-mapping>

4.3PersonService.java 面向接口编程

package cn.itcast.service;import java.util.List;import cn.itcast.bean.Person;public interface PersonService {public void save(Person person);public void update(Person person);public Person getPerson(Integer personid);public void delete(Integer personid);public List<Person> getPersons();}

4.4PersonServiceBean.java继承PersonService接口实现对数据库的操作

package cn.itcast.service.impl;import java.util.List;import javax.annotation.Resource;import org.hibernate.SessionFactory;import org.springframework.transaction.annotation.Propagation;import org.springframework.transaction.annotation.Transactional;import cn.itcast.bean.Person;import cn.itcast.service.PersonService;@Transactionalpublic class PersonServiceBean implements PersonService {@Resource private SessionFactory sessionFactory;public void save(Person person){sessionFactory.getCurrentSession().persist(person);}public void update(Person person){sessionFactory.getCurrentSession().merge(person);}@Transactional(propagation=Propagation.NOT_SUPPORTED,readOnly=true)public Person getPerson(Integer personid){return (Person)sessionFactory.getCurrentSession().get(Person.class, personid);}public void delete(Integer personid){sessionFactory.getCurrentSession().delete(sessionFactory.getCurrentSession().load(Person.class, personid));}@Transactional(propagation=Propagation.NOT_SUPPORTED,readOnly=true)@SuppressWarnings("unchecked")public List<Person> getPersons(){return sessionFactory.getCurrentSession().createQuery("from Person").list();}}

5.进行测试使用junit4

PersonServiceTest.java 运行观察数据库。

package junit.test;import static org.junit.Assert.*;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;@BeforeClasspublic static void setUpBeforeClass() throws Exception {try {ApplicationContext applicationContext = new ClassPathXmlApplicationContext("beans.xml");personService = (PersonService)applicationContext.getBean("personService");} catch (RuntimeException e) {e.printStackTrace();}}@Testpublic void testSave() {personService.save(new Person("呵呵"));}@Testpublic void testUpdate() {Person person = personService.getPerson(1);//....person.setName("嘻嘻");personService.update(person);}@Testpublic void testGetPerson() {Person person = personService.getPerson(2);System.out.println(person.getName());try {System.out.println("请关闭数据库");Thread.sleep(1000*15);} catch (InterruptedException e) {e.printStackTrace();}System.out.println("第二次开始获取");person = personService.getPerson(2);System.out.println(person.getName());}@Testpublic void testDelete() {personService.delete(1);}@Testpublic void testGetPersons() {List<Person> persons = personService.getPersons();for(Person person : persons){System.out.println(person.getName());}}}

二.以上测试成功后，开始集成struts2

1.struts.xml中<constant name="struts.objectFactory" value="spring" />把action的创建交给spring管理，需导入struts2-spring-plugin-2.1.8.jar。

2.struts.xml中class="personList

<result name="list">/WEB-INF/page/personlist.jsp</result>

<result name="add">/WEB-INF/page/addperson.jsp</result>风格

</action>

beans.xml中id="personList"

他们的class和id中都一样是personList

上面这个要注意

struts.xml也放在src目录下

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" "http://struts.apache.org/dtds/struts-2.0.dtd"><struts>    <constant name="struts.action.extension" value="do"/>  <constant name="struts.serve.static.browserCache" value="false"/>  <constant name="struts.configuration.xml.reload" value="true"/>  <constant name="struts.devMode" value="true" />  <constant name="struts.ui.theme" value="simple" /> <constant name="struts.objectFactory" value="spring" /> <package name="person" namespace="/person" extends="struts-default"> <global-results> <result name="message">/WEB-INF/page/message.jsp</result> </global-results><action name="action_*" class="personList" method="{1}"><result name="list">/WEB-INF/page/personlist.jsp</result><result name="add">/WEB-INF/page/addperson.jsp</result></action> </package></struts>

2.编写action

PersonAction.java

package cn.itcast.web;import java.util.List;import javax.annotation.Resource;import cn.itcast.bean.Person;import cn.itcast.service.PersonService;public class PersonAction {@Resource PersonService personService;private String message;private List<Person> persons;private Person person;private String name;public PersonService getPersonService() { return personService; } public void setPersonService(PersonService personService) { this.personService = personService; } public String getName() { return name; } public void setName(String name) { this.name = name; } public Person getPerson() {return person;}public void setPerson(Person person) {this.person = person;}/** * 人员列表显示 */public String list(){//this.persons = personService.getPersons();this.persons=personService.getPersons();return "list";}/** * 人员添加界面 */public String addUI(){return "add";}/** * 人员添加 */public String add(){this.personService.save(this.person);this.message="添加成功";return "message";}public List<Person> getPersons() {return persons;}public void setPersons(List<Person> persons) {this.persons = persons;}public String getMessage() {return message;}public void setMessage(String message) {this.message = message;}}

3.测试页面

hello.jsp提交页面

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%><%String path = request.getContextPath();String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";%><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html> <head> <base href="<%=basePath%>"> <title>My JSP 'index.jsp' starting page</title><meta http-equiv="pragma" content="no-cache"><meta http-equiv="cache-control" content="no-cache"><meta http-equiv="expires" content="0"> <meta http-equiv="keywords" content="keyword1,keyword2,keyword3"><meta http-equiv="description" content="This is my page"> </head> <body> <form action="<%=request.getContextPath()%>/person/action_list.do" method="post"> 用户名<input type="text" name="name"> <input type="submit" value="提交"> </form> </body></html>

personlist.jsp显示页面

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%><%@ taglib uri="/struts-tags" prefix="s"%><!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"> <meta http-equiv="keywords" content="keyword1,keyword2,keyword3"><meta http-equiv="description" content="This is my page"> </head> <body> <s:iterator value="persons"> id=<s:property value="id"/>,name=<s:property value="name"/><br> </s:iterator> ${name} </body></html>
