Spring、Struts2+Spring+Hibernate整合步骤
所使用的Jar包：
Hibernate：
Spring（使用MyEclipse自动导入框架功能）
Struts2:
注解包和MySql驱动包：
1、配置Hibernate和Spring：
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop" 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/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"> <context:annotation-config /> <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> <property name="driverClassName" value="com.mysql.jdbc.Driver" /> <property name="url" value="jdbc:mysql://localhost:3306/ssh?useUnicode=true&characterEncoding=UTF-8" /> <property name="username" value="root" /> <property name="password" value="" /> <!--初始化时获取的连接数，取值应在minPoolSize与maxPoolSize之间。Default: 3 --> <property name="initialSize" value="1" /> <!--连接池中保留的最大连接数。Default: 15 --> <property name="maxActive" value="500" /> <!--最大空闲值,当经过一段峰值以后，连接会被释放掉一部分，直到释放到maxidle --> <property name="maxIdle" value="2" /> <!--最小空闲值 当空闲的连接数小于阀值时，连接池会主去的去申请一些连接 --> <property name="minIdle" value="1" /> </bean> <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean" > <property name="dataSource" ref="dataSource" /> <property name="mappingResources"> <list> <value>cn/raffaello/hbm/Person.hbm.xml</value> </list> </property> <property name="hibernateProperties"> <value> hibernate.dialect=org.hibernate.dialect.MySQL5Dialect hibernate.hbm2ddl.auto=update hibernate.show_sql=true hibernate.format_sql=false </value> </property> </bean> <bean id="txManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory" /> </bean> <tx:annotation-driven transaction-manager="txManager"/> <bean id="personIDao" class="cn.raffaello.dao.impl.PersonDaoImpl" /> <bean id="personIService" class="cn.raffaello.service.impl.PersonServiceImpl"> <property name="personIDao" ref="personIDao" /> </bean> </beans>
2、新建实体和映射文件：
public class Person {
public Person(){}
public Person(String name) {
super();
this.name = name;
}
private Integer id;
private String 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;
}
}
<hibernate-mapping package="cn.raffaello.model"> <class name="Person" table="PERSON"> <id name="id" column="ID"> <generator class="native" /> </id> <property name="name" column="NAME" /> </class> </hibernate-mapping>
3、新建DaoBean，并在Bean中实现部分方法，使用@Resource给SessionFactory注入:
public interface PersonIDao {
void add(Person person);
void update(Person person);
Person getById(Integer id);
List<Person> getPersons();
}public class PersonDaoImpl implements PersonIDao {
@Resource(name="sessionFactory")
private SessionFactory sessionFactory;
@Override
public void add(Person person) {
sessionFactory.getCurrentSession().persist(person);
}
@Override
public void update(Person person) {
sessionFactory.getCurrentSession().merge(person);
}
@Override
public Person getById(Integer id) {
return (Person)sessionFactory.getCurrentSession().get(Person.class, id);
}
@SuppressWarnings("unchecked")
@Override
public List<Person> getPersons() {
return sessionFactory.getCurrentSession().createQuery("from Person").list();
}
}
5、新建ServiceBean，并实现部分方法；在ServiceBean的头部添加@Transactional 注解，使用该ServiceBean纳入Spring事务管理；
public interface PersonIService {
void add(Person person);
void update(Person person);
Person getById(Integer id);
List<Person> getPersons();
}
@Transactional
public class PersonServiceImpl implements PersonIService {
private PersonIDao personIDao;
@Override
public void add(Person person) {
personIDao.add(person);
}
@Override
public void update(Person person) {
personIDao.update(person);
}
@Transactional(readOnly=true)
@Override
public Person getById(Integer id) {
return personIDao.getById(id);
}
@Transactional(readOnly=true)
@Override
public List<Person> getPersons() {
return personIDao.getPersons();
}
public PersonIDao getPersonIDao() {
return personIDao;
}
public void setPersonIDao(PersonIDao personIDao) {
this.personIDao = personIDao;
}
}6、测试Spring和Hibernate的代码：
public class test {
private static PersonIService personIService;
@BeforeClass
public static void init(){
ApplicationContext cxt=new ClassPathXmlApplicationContext("beans.xml");
personIService=(PersonIService)cxt.getBean("personIService");
}
@Test
public void test() {
personIService.add(new Person("克露丝"));
personIService.add(new Person("Json"));
personIService.add(new Person("布尔曼"));
personIService.add(new Person("HHH"));
personIService.add(new Person("汤姆"));
}
@Test
public void testUpdate(){
Person person=personIService.getById(1);
person.setName("汉克丝 hankesi");
personIService.update(person);
}
@Test
public void testList(){
List<Person> list=personIService.getPersons();
for(Person per : list){
System.out.println(per.getName());
}
}
}7、整合Struts2+Spring+Hibernate，将下面代码添加到Web.xml中：
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:beans.xml</param-value>
</context-param>
<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>8、在Struts.xml中 进行如下配置：
<constant name="struts.118n.encoding" value="UTF-8" />
<!-- Action 后缀 -->
<constant name="struts.action.extension" value="do,action" />
<!-- 设置浏览器是否缓存静态内容，默认值为true,开发环境下建议设置为false -->
<constant name="struts.serve.static.browserCache" value="false" />
<!-- 当Struts 修改文件以后，是否重新加载该文件，默认为false,推荐开发环境下设置为true -->
<constant name="struts.configuration.xml.reload" value="true" />
<!-- 开发模式下可以打印更详细的错误信息 -->
<constant name="struts.devMode" value="false" />
<!-- 默认视图主题 -->
<constant name="struts.ui.theme" value="simple" />
<!-- 与Spring集成是，指定有Spring创建Action对象 -->
<constant name="struts.objectFactory" value="spring" />
<package name="raffaello" namespace="/raffaello" extends="struts-default">
<action name="main_*" class="cn.raffaello.action.MainAction" method="{1}">
<result name="message">/WEB-INF/pages/message.jsp</result>
<result name="list">/WEB-INF/pages/list.jsp</result>
</action>
</package>9、新建Action：MainAction:
public class MainAction {
private String message;
private Person person;
private PersonIService personIService;
public String hello(){
setMessage("struts2 测试消息！");
return "message";
}
public String save(){
if(person!=null && !person.getName().equals("")){
personIService.add(person);
setMessage("添加成功");
}else{
setMessage("对象为空");
}
return "message";
}
public String list(){
List<Person> list=personIService.getPersons();
HttpServletRequest request=ServletActionContext.getRequest();
request.setAttribute("PersonList", list);
return "list";
}
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
public Person getPerson() {
return person;
}
public void setPerson(Person person) {
this.person = person;
}
public PersonIService getPersonIService() {
return personIService;
}
public void setPersonIService(PersonIService personIService) {
this.personIService = personIService;
}
}10、添加测试代码和获取的测试代码：
<form action="/SSH2/raffaello/main_save.do" method="post">
添加人员 <a target="_blank" href="/SSH2/raffaello/main_list.do">人员列表</a>
<hr />
姓名：<input type="text" name="person.name" />
<input type="submit" value="提交">
</form><span style="white-space:pre"> </span><c:forEach items="${PersonList}" var="per">
${per.name}
</c:forEach>
