二：搭建整个项目结构

SSH(Spring+struts2+hibernate)整合版详解

 

beans层
public class StudentSSH {
    private int id;
    private String name;

    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
}

<?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">
        <!-- 映射文件开始 -->
<hibernate-mapping package="cn.sjl.beans">
<!--表名称-->
<class name="StudentSSH" table="STUDENTSSH">
    <!--列名-->
    <id name="id" column="ID">
        <!--主键生成的策略  native：自动生成主键字段-->
        <generator class="native"></generator>
    </id>
    <property name="name" column="NAME"></property>
</class>
</hibernate-mapping>

dao层
public interface IStudentDAO {
    /**
     * 添加学生
     * @param student
     * @return
     */
    public int add(StudentSSH student);
}

public class StudentDAOImpl implements IStudentDAO {
    //注入SessionFactory工厂
    private SessionFactory sessionFactory;
    //添加
    public int add(StudentSSH student) {
        Serializable count = sessionFactory.getCurrentSession().save(student);
        return (Integer)count;
    }

    public SessionFactory getSessionFactory() {
        return sessionFactory;
    }
    public void setSessionFactory(SessionFactory sessionFactory) {
        this.sessionFactory = sessionFactory;
    }

}

service层
public interface IStudentService {
    /**
     * 添加学生
     * @param student
     * @return
     */
    public int add(StudentSSH student);
}

public class StudentServiceImpl implements IStudentService {
    //注入dao层的接口
    private IStudentDAO dao;
    public IStudentDAO getDao() {
        return dao;
    }
    public void setDao(IStudentDAO dao) {
        this.dao = dao;
    }

    /**
     * 添加
     * @param student
     * @return
     */
    @Transactional
    public int add(StudentSSH student) {
        int result = dao.add(student);
        return result;
    }
}

action层
public class StudentAction extends ActionSupport {
    private StudentSSH studentSSH;
    private IStudentService studentService;
    /**
     * 新增
     * @return
     */
    public String Add(){
        int count= studentService.add(studentSSH);
        if (count>0){
            return SUCCESS;
        }else {
            return LOGIN;
        }

    }

    public StudentSSH getStudentSSH() {
        return studentSSH;
    }
    public void setStudentSSH(StudentSSH studentSSH) {
        this.studentSSH = studentSSH;
    }

    public IStudentService getStudentService() {
        return studentService;
    }
    public void setStudentService(IStudentService studentService) {
        this.studentService = studentService;
    }
}

三：书写配置文件
applicationContext.xml文件
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xmlns:context="http://www.springframework.org/schema/context"
       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/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="${jdbc.driverClass}"></property>
        <property name="jdbcUrl" value="${jdbc.jdbcUrl}"></property>
        <property name="user" value="${jdbc.user}"></property>
        <property name="password" value="${jdbc.password}"></property>
    </bean>

    <!--识别jdbc.properties-->
    <context:property-placeholder location="classpath:jdbc.properties"></context:property-placeholder>

    <!--sessionfactory工厂-->
    <bean id="factory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
        <property name="dataSource" ref="dataSource"></property>
         <property name="hibernateProperties">
             <props>
                 <!--控制台打印SQL语句-->
                 <prop key="hibernate.show_sql">true</prop>
                 <!--格式化sql-->
                 <prop key="hibernate.format_sql">true</prop>
                 <!--方言-->
                 <prop key="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</prop>
                 <!--绑定线程-->
                 <prop key="hibernate.current_session_context_class">org.springframework.orm.hibernate5.SpringSessionContext</prop>
             </props>
         </property>
        <!--扫描小配置文件-->
        <property name="mappingDirectoryLocations" value="classpath:cn/sjl/beans"></property>
    </bean>

    <!--dao层-->
    <bean id="studentDAO" class="cn.sjl.dao.StudentDAOImpl">
        <property name="sessionFactory" ref="factory"></property>
    </bean>

    <!--service层-->
    <bean id="studentService" class="cn.sjl.service.StudentServiceImpl">
        <property name="dao" ref="studentDAO"></property>
    </bean>

   <!--创建struts层    struts默认为多例-->
    <bean id="StudentAction" class="cn.sjl.action.StudentAction" scope="prototype">
        <property name="studentService" ref="studentService"></property>
    </bean>

    <!--事务管理器-->
    <bean id="transactionManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager">
          <property name="sessionFactory" ref="factory"></property>
    </bean>

    <!--事务-->
    <tx:annotation-driven transaction-manager="transactionManager"></tx:annotation-driven>
</beans>

struts.xml文件
<?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.objectFactory" value="spring"></constant>
    <package name="result" namespace="/" extends="struts-default">
     <action name="add" class="StudentAction" method="Add">
         <result name="success">/jsp/index.jsp</result>
         <result name="login">/jsp/add.jsp</result>
     </action>
    </package>
</struts>

jdbc.properties文件
jdbc.driverClass=oracle.jdbc.driver.OracleDriver
jdbc.jdbcUrl=jdbc:oracle:thin:@localhost:1521:orcl
jdbc.user=root
jdbc.password=root

四：web.xml文件（这个不能少）
<context-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>classpath:applicationContext.xml</param-value>
</context-param>
<filter>
  <filter-name>struts</filter-name>
  <!--核心控制器-->
  <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>
<!--监听器-->
<listener>
  <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

五：jsp页面
<%@ taglib prefix="s" uri="/struts-tags" %>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>添加</title>
</head>
<body>
<s:debug></s:debug>
<h2>sshxml整合</h2>
<form  method="post" action="/add">
    姓名：<input type="text" name="studentSSH.name">
    <input type="submit" value="添加">
</form>
</body>
</html>

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