struts2+hibernate+spring配置详解

struts2+hibernate+spring配置详解

哎 ，当初一个人做好难，现在终于弄好了，希望自学这个的能少走些弯路。

以下是自己配置的案例
注意，要想明白的比较好，请下载这个配套的资料，献给初学者（这是获取资料的超链接，点击下载）
配置完成后

1，建立web项目ssh51
2,导入所有的jar包，包括Struts2,spring,hibernate

3.在项目下建立3个资源文件

4，建立持久化类和文件

package com.biluo.domain;public class Person {    private Integer id;    private String  name;    private String password;    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;    }    public String getPassword() {        return password;    }    public void setPassword(String password) {        this.password = password;    }}

<?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="com.biluo.domain">    <class name="Person" table="person">        <id name="id" type="java.lang.Integer" column="id">        <!--generator用于指定主键的生成策略， hilo native increment sequence uuid  -->           <generator class="native" />        </id>        <property name="name" type="java.lang.String" >            <column name="name"  />        </property>          <property name="password" type="java.lang.String" >            <column name="password"  />        </property>    </class></hibernate-mapping>

5，在config目录下建立3个配置包 分别是 struts2 ，hibernate ，spring

6,建立一个hibernate.cfg.xml配置文件

<?xml version='1.0' encoding='utf-8'?><!DOCTYPE hibernate-configuration PUBLIC        "-//Hibernate/Hibernate Configuration DTD 3.0//EN"        "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"><hibernate-configuration>    <!-- 一个sessionFactory代表数据库的一个连接 --><session-factory></session-factory></hibernate-configuration>

7.配置Spring，模块化

/ssh51/config/spring/applicationContext.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"    xmlns:ehcache="http://www.springmodules.org/schema/ehcache"    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             http://www.springmodules.org/schema/ehcache             http://www.springmodules.org/schema/cache/springmodules-ehcache.xsd">    <import resource="applicationContext-db.xml"/><!-- 引入数据库配置文件 -->    <import resource="applicationContext-people.xml"/><!-- 引入项模块 --></beans>

/ssh51/config/spring/applicationContext-db.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"    xmlns:ehcache="http://www.springmodules.org/schema/ehcache"    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             http://www.springmodules.org/schema/ehcache             http://www.springmodules.org/schema/cache/springmodules-ehcache.xsd">    <!-- 按照指定的路径加载配置文件 -->    <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></beans>

/ssh51/config/spring/applicationContext-people.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"    xmlns:ehcache="http://www.springmodules.org/schema/ehcache"    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             http://www.springmodules.org/schema/ehcache             http://www.springmodules.org/schema/cache/springmodules-ehcache.xsd"></beans>

8，配置数据库连接参数，写在一个文件中比较科学
/ssh51/config/jdbc.properties

jdbc.driverClassName=com.mysql.jdbc.Driverjdbc.url=jdbc\:mysql\://localhost\:3306/spring_hibernatejdbc.username=rootjdbc.password=541711153

9，配置sessionFactory这个很重要
/ssh51/config/spring/applicationContext-db.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"    xmlns:ehcache="http://www.springmodules.org/schema/ehcache"    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             http://www.springmodules.org/schema/ehcache             http://www.springmodules.org/schema/cache/springmodules-ehcache.xsd">    <!-- 按照指定的路径加载配置文件 -->    <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>    <bean id="sessionFactory"  class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">        <property name="dataSource"><ref bean="dataSource" /></property>        <property name="mappingDirectoryLocations">            <list>                <value>classpath:com/biluo/domain</value><!-- 配置映射文件的路径 -->            </list>        </property>        <property name="hibernateProperties">            <props>                <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>                <!--控制台显示sql语句 -->                <prop key="hibernate.show_sql">true</prop>                <prop key="hibernate.format_sql">false</prop>                <prop key="hibernate.hbm2ddl.auto">update</prop>            </props>        </property>    </bean></beans>

10..好了，这里进入很重要的一步，必须测试，否者下面的不用看了，测试sessionfactory

package com.biluo.test;import org.junit.Test;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;public class SessionFactoryTest {    @Test    public void testSessionFactory(){        ApplicationContext context =     new ClassPathXmlApplicationContext("spring/applicationContext.xml");        context.getBean("sessionFactory");    }}

注意：这里要引入测试类，否者会报莫名其妙的错误
这一步，没做对的，就不要往下看了，一定要对了，才能继续

11.可以编写dao层，和service层了，这里要用接口编程，否者spring就没意义了，接口在 下面理解为代理对象

package com.biluo.dao;import com.biluo.domain.Person;public interface  PersonDao {    public void savePerson(Person person);}

package com.biluo.dao.impl;import org.springframework.orm.hibernate3.support.HibernateDaoSupport;import com.biluo.dao.PersonDao;import com.biluo.domain.Person;public class PersonDaoImpl extends HibernateDaoSupport implements PersonDao{    public void savePerson(Person person) {        // TODO Auto-generated method stub        this.getHibernateTemplate().save(person);    }}

package com.biluo.service;import com.biluo.domain.Person;public interface PersonService {    public void savePerson(Person person);}

package com.biluo.service.impl;import com.biluo.dao.PersonDao;import com.biluo.domain.Person;import com.biluo.service.PersonService;public class PersonServiceImpl implements PersonService{    private PersonDao personDao;    public void setPersonDao(PersonDao personDao) {        this.personDao = personDao;    }    public void savePerson(Person person) {        // TODO Auto-generated method stub        personDao.savePerson(person);    }}

12.下面要配置事务了

<?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"    xmlns:ehcache="http://www.springmodules.org/schema/ehcache"    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             http://www.springmodules.org/schema/ehcache             http://www.springmodules.org/schema/cache/springmodules-ehcache.xsd">    <!-- 按照指定的路径加载配置文件 -->    <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>    <bean id="sessionFactory"  class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">        <property name="dataSource"><ref bean="dataSource" /></property>        <property name="mappingDirectoryLocations">            <list>                <value>classpath:com/biluo/domain</value><!-- 配置映射文件的路径 -->            </list>        </property>        <property name="hibernateProperties">            <props>                <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>                <!--控制台显示sql语句 -->                <prop key="hibernate.show_sql">true</prop>                <prop key="hibernate.format_sql">false</prop>                <prop key="hibernate.hbm2ddl.auto">update</prop>            </props>        </property>    </bean>    <!-- 这个不配置会默认提交事务的，而且不是经过代理对象，结果会被写到数据库的 --><bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">        <property name="sessionFactory">            <ref bean="sessionFactory"/>        </property>    </bean>    <tx:advice id="tx" transaction-manager="transactionManager">        <tx:attributes>            <tx:method name="save*"  propagation="NOT_SUPPORTED"  read-only="false"/>        </tx:attributes>    </tx:advice>    <aop:config>        <aop:pointcut expression="execution(* com.biluo.service.impl.PersonServiceImpl.*.*(..))"             id="perform"/>        <aop:advisor advice-ref="tx" pointcut-ref="perform"/>    </aop:config></beans>

13.配置applicationContext-person.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"    xmlns:ehcache="http://www.springmodules.org/schema/ehcache"    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             http://www.springmodules.org/schema/ehcache             http://www.springmodules.org/schema/cache/springmodules-ehcache.xsd">    <bean id="personDao" class="com.biluo.dao.impl.PersonDaoImpl">        <property name="sessionFactory">            <ref bean="sessionFactory"/>        </property>    </bean>    <bean id="personService" class="com.biluo.service.impl.PersonServiceImpl">        <property name="personDao">            <ref bean="personDao"/>        </property>    </bean></beans>

14.可以测试service和dao层了

package com.biluo.test;import org.junit.Test;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;import com.biluo.domain.Person;import com.biluo.service.PersonService;public class PersonServiceTest {    @Test     public void testPersonService(){        ApplicationContext context = new ClassPathXmlApplicationContext("spring/applicationContext.xml");        PersonService personService =                 (PersonService)context.getBean("personService");        Person person = new Person();        person.setName("aaa");        personService.savePerson(person);    }}

15,建立action

package com.biluo.action;import com.biluo.domain.Person;import com.biluo.service.PersonService;import com.opensymphony.xwork2.ActionSupport;public class PersonAction extends ActionSupport {    private PersonService personService;    private Person person;    public Person getPerson() {        return person;    }    public void setPerson(Person person) {        this.person = person;    }    public void setPersonService(PersonService personService) {        this.personService = personService;    }    public String savePerson(){        this.personService.savePerson(person);        return "success";    }}

16，配置Action

<?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"    xmlns:ehcache="http://www.springmodules.org/schema/ehcache"    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             http://www.springmodules.org/schema/ehcache             http://www.springmodules.org/schema/cache/springmodules-ehcache.xsd">    <bean id="personDao" class="com.biluo.dao.impl.PersonDaoImpl">        <property name="sessionFactory">            <ref bean="sessionFactory"/>        </property>    </bean>    <bean id="personService" class="com.biluo.service.impl.PersonServiceImpl">        <property name="personDao">            <ref bean="personDao"/>        </property>    </bean>    <bean id="personAction" class="com.biluo.action.PersonAction"         scope="prototype"><!-- scope="prototype"这一点要是，因为action是多个实例的 -->        <property name="personService">            <ref bean="personService"/>        </property>    </bean></beans>

17.添加struts配置文件，也要模块化
/ssh51/config/struts.xml

<?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.il8n.encoding" value="UTF-8" />    <constant name="struts.ui.theme" value="simple"/>    <!-- <constant name="struts.devMode" value="true"/> -->    <include file="struts2/struts-person.xml"></include></struts>

/ssh51/config/struts2/struts-person.xml

<?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>    <package name="default" namespace="/" extends="struts-default">         <!--在Struts配置文件中配置action，但是他的class属性不再指向action的实现类             ，而是指向spring容器的action实例的id         -->          <action name="personAction_*" class="personAction" method="{1}">              <result name="input">/login.jsp</result>             <result name="success">/success.jsp</result>         </action>     </package>  </struts>

18.配置web.xml

<?xml version="1.0" encoding="UTF-8"?><web-app version="2.5"     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_2_5.xsd">  <display-name></display-name>   <welcome-file-list>        <welcome-file>login.jsp</welcome-file>    </welcome-file-list>    <!-- 配置spring资源 -->    <context-param>        <param-name>contextConfigLocation</param-name>        <!-- 这一点配错路径 会报这个错误No bean named 'sessionFactory ' is defined -->        <param-value>classpath:/spring/applicationContext.xml</param-value>    </context-param>    <filter>    <filter-name>OpenSessionInViewFilter</filter-name>    <filter-class>     org.springframework.orm.hibernate3.support.OpenSessionInViewFilter    </filter-class>    <init-param>     <param-name>sessionFactoryBeanName</param-name>     <param-value>sessionFactory</param-value>    </init-param>    <init-param>             <param-name>singleSession</param-name>             <param-value>true</param-value>                    </init-param>         <init-param>         <param-name>flushMode</param-name>    <param-value>AUTO</param-value>                 </init-param> </filter> <filter-mapping>    <filter-name>OpenSessionInViewFilter</filter-name>    <url-pattern>/*</url-pattern> </filter-mapping>     <!-- 配置spring -->    <listener>        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>    </listener>    <!--struts2的过滤器 -->    <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>

19，编写jsp注册页面
/ssh51/WebRoot/login.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%><%@ taglib prefix="s" uri="/struts-tags"%><%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 'login.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">    <!--    <link rel="stylesheet" type="text/css" href="styles.css">    -->  </head>  <body><form action="personAction_savePerson.action" method="post">    <input type="text" name="person.name" value="${person.name}"/>    <input type="password" name="person.password" value="${person.password}"/>    <input type="submit" value="注册"/></form>  </body></html>

/ssh51/WebRoot/success.jsp

<%@ 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 'success.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">    <!--    <link rel="stylesheet" type="text/css" href="styles.css">    -->  </head>  <body>     恭喜你  配置成功 <br>  </body></html>

运行如果没有报错，而且jsp页面的数据被写入到数据库，就说明配置成功了
