使用Struts，spring和HibernateXML方式进行整合

书写持久层

public class Dept {    private Integer deptno;    private String deptname;    public Integer getDeptno() {        return deptno;    }    public void setDeptno(Integer deptno) {        this.deptno = deptno;    }    public String getDeptname() {        return deptname;    }    public void setDeptname(String deptname) {        this.deptname = deptname;    }}

持久层对应的配置文件

<?xml version="1.0"?><!DOCTYPE hibernate-mapping PUBLIC        "-//Hibernate/Hibernate Mapping DTD 3.0//EN"        "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd"><hibernate-mapping package="cn.happy.bean">    <class name="Dept" table="Dept">        <id name="deptno" column="deptno">            <generator class="native"></generator>        </id>        <property name="deptname"></property>    </class></hibernate-mapping>

书写dao层接口

public interface DeptDao {    public void addDept(Dept dept);}
dao层接口的实现类

public class DeptImpl implements DeptDao {    private SessionFactory sessionFactory;    public void addDept(Dept dept) {        Session session = sessionFactory.getCurrentSession();        session.save(dept);    }    public SessionFactory getSessionFactory() {        return sessionFactory;    }    public void setSessionFactory(SessionFactory sessionFactory) {        this.sessionFactory = sessionFactory;    }}

书写service层

public interface DeptService {    public void addDept(Dept dept);}

service层接口的实现

@Transactionalpublic class DeptServiceImpl implements DeptService {    private DeptImpl dao;    public void addDept(Dept dept) {        dao.addDept(dept);    }    public DeptImpl getDao() {        return dao;    }    public void setDao(DeptImpl dao) {        this.dao = dao;    }}

action层定义DeptAction

public class DeptAction extends ActionSupport {    private Dept dept;    private DeptService service;    public String Hello(){        service.addDept(dept);        return  SUCCESS;    }    public DeptService getService() {        return service;    }    public void setService(DeptService service) {        this.service = service;    }    public Dept getDept() {        return dept;    }    public void setDept(Dept dept) {        this.dept = dept;    }

编写配置文件

applicationContext.xml
<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"       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:xsi="http://www.w3.org/2001/XMLSchema-instance"       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd     http://www.springframework.org/schema/context  http://www.springframework.org/schema/context/spring-context.xsd     http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd     http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd">    <!--数据源-->    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">        <property name="driverClass" value="${jdbc.driverClassName}"/>        <property name="user" value="${jdbc.username}"/>        <property name="password" value="${jdbc.password}"/>        <property name="jdbcUrl" value="${jdbc.url}"/>    </bean>    <!--jdbc.properties-->    <context:property-placeholder location="classpath:jdbc.properties"></context:property-placeholder>    <!--2.SessionFactory         类：Local-->    <bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">        <property name="dataSource" ref="dataSource"></property>        <property name="hibernateProperties">            <props>                <!--hibernate.xxxxxx必须以hibernate-->                <prop key="hibernate.show_sql">true</prop>                <prop key="hibernate.format_sql">true</prop>                <prop key="hibernate.hbm2ddl.auto">update</prop>                <prop key="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</prop>                <!--with current thread bind session和线程绑定的session-->                <prop key="hibernate.current_session_context_class">org.springframework.orm.hibernate5.SpringSessionContext</prop>            </props>        </property>        <!--扫描小配置文件 所有的hbm文件-->        <property name="mappingDirectoryLocations" value="classpath:cn/happy/bean"></property>    </bean>    <!--3.dao-->    <bean id="deptDAO" class="cn.happy.dao.impl.DeptImpl">        <property name="sessionFactory" ref="sessionFactory"></property>    </bean>    <!--4.service-->    <bean id="deptService" class="cn.happy.service.impl.DeptServiceImpl">        <property name="dao" ref="deptDAO"></property>    </bean>    <!--要用Spring去创建Action对象  Struts2的Action是多例的-->    <bean id="deptAction" class="cn.happy.action.DeptAction" scope="prototype">        <property name="service" ref="deptService"></property>    </bean>    <!--  6.事务管理器-->    <bean id="transactionManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager">        <property name="sessionFactory" ref="sessionFactory"></property>    </bean>    <!--7.事务-->    <tx:annotation-driven transaction-manager="transactionManager"></tx:annotation-driven></beans>

数据库链接的jdbc.properties文件

jdbc.driverClassName=oracle.jdbc.OracleDriverjdbc.url=jdbc:oracle:thin:@localhost:1521:orcljdbc.username=rootjdbc.password=root
struts文件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.devMode" value="true"></constant>    <!--将对象工厂的生成权设置成spring-->    <!-- <constant name="struts.objectFactory" value="spring"></constant>-->    <package name="default" namespace="/" extends="struts-default">        <action name="add" class="deptAction" method="Hello">            <result>/index.jsp</result>        </action>    </package></struts>
编写WEB-INF下的web.xml

web.xml主要作用就是在程序启动时加载配置文件，添加过滤器和拦截器

web.xml

<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd" ><web-app>  <display-name>Archetype Created Web Application</display-name>  <context-param>    <param-name>contextConfigLocation</param-name>    <param-value>classpath:applicationContext.xml</param-value>  </context-param>  <filter>    <filter-name>struts</filter-name>    <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>  </filter>  <filter-mapping>    <filter-name>struts</filter-name>    <url-pattern>/*</url-pattern>  </filter-mapping>  <!--1.监听器-->  <listener>    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  </listener></web-app>

简单的测试add.jsp和index.jsp如果添加成功直接跳转到页面index

add.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %><html><head>    <title>添加页面</title></head><body><form action="/add" method="post">    部门名称：<input  name="dept.deptname"/>    <input type="submit"/></form></body></html>
index.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %><html><head>    <title>成功</title></head><body><h2>添加成功！！！</h2></body></html>
