快速搭建ssh项目

环境：oracle11g、myeclipse2014

首先在web项目中添加spring框架

现在已经添加完spring框架了

然后我们开始添加Hibernate框架

到这一步Hibernate框架就添加完成了

applicationContext.xml配置文件

<?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:p="http://www.springframework.org/schema/p"
    xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd">


    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
        <property name="url" value="jdbc:oracle:thin:@127.0.0.1:1521:orcl">
        </property>
        <property name="username" value="system"></property>
        <property name="password" value="1234"></property>
        <property name="driverClassName" value="oracle.jdbc.driver.OracleDriver"></property>
    </bean>
    <bean id="sessionFactory"
        class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
        <property name="dataSource">
            <ref bean="dataSource" />
        </property>
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">
                    org.hibernate.dialect.Oracle9Dialect
                </prop>
                <prop key="hibernate.show_sql">true</prop>
                <prop key="hibernate.format_sql">true</prop>
            </props>
        </property>
        <!-- <property name="annotatedClasses"> <list> <value>com.bdqn.pojo.Dept</value> 
            <value>com.bdqn.pojo.Emp</value> </list> </property> -->
        <property name="packagesToScan" value="com.bdqn.pojo"></property>
    </bean>
    
    <context:component-scan base-package="com.bdqn" />
    
    <bean id="txManager"
        class="org.springframework.orm.hibernate3.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory"></property>
    </bean>
    
    <tx:annotation-driven transaction-manager="txManager" />

</beans>

然后开始配置struts2框架

到现在struts2框架也整合进来了

然后使用Hibernate的反向工程创建实体类

点击finish，然后实体类就创建好了，接下来就可以开始写代码了

dao层接口

package com.bdqn.dao;

import java.util.List;

import com.bdqn.pojo.Emp;

public interface EmpDao {

    public List<Emp> findAll();
}

dao层实现

package com.bdqn.dao.impl;

import java.util.List;

import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import org.springframework.stereotype.Repository;

import com.bdqn.dao.EmpDao;
import com.bdqn.pojo.Emp;

@Repository("empDao")
public class EmpDaoImpl extends HibernateDaoSupport implements EmpDao {

    @Autowired
    public EmpDaoImpl(@Qualifier("sessionFactory") SessionFactory sessionFactory) {
          this.setSessionFactory(sessionFactory);
    }
    public EmpDaoImpl() {
    }
    
    @Override
    public List<Emp> findAll() {
        // TODO Auto-generated method stub
        return this.getHibernateTemplate().find("from Emp");
    }

}

service层接口

package com.bdqn.service;

import java.util.List;

import com.bdqn.pojo.Emp;

public interface EmpService {

    public List<Emp> findAll();
}

service层实现

package com.bdqn.service.impl;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import com.bdqn.dao.EmpDao;
import com.bdqn.pojo.Emp;
import com.bdqn.service.EmpService;

@Service("empService")
@Transactional
public class EmpServiceImpl implements EmpService {

    @Autowired
    private EmpDao empDao;
    
    public EmpDao getEmpDao() {
        return empDao;
    }

    public void setEmpDao(EmpDao empDao) {
        this.empDao = empDao;
    }

    @Override
    @Transactional(readOnly = true)
    public List<Emp> findAll() {
        // TODO Auto-generated method stub
        return empDao.findAll();
    }

}

Action（web）：

package com.bdqn.web;

import java.util.List;
import java.util.Map;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;

import com.bdqn.pojo.Emp;
import com.bdqn.service.EmpService;
import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionSupport;

@Controller
public class EmpAction extends ActionSupport {

    @Autowired
    private EmpService empService;

    public EmpService getEmpService() {
        return empService;
    }

    public void setEmpService(EmpService empService) {
        this.empService = empService;
    }
    
    public String execute(){
        Map<String, Object> request = (Map<String, Object>) ActionContext.getContext().get("request");
        List<Emp> emps = empService.findAll();
        request.put("emps", emps);
        return SUCCESS;
    }
}

struts.xml配置文件

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">
<struts>
    <package name="def" namespace="/" extends="struts-default">
        <action name="empAction" class="com.bdqn.web.EmpAction">
            <result>/index.jsp</result>
        </action>
    </package>
</struts>

jsp页面：

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%
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">
    <!--
    <link rel="stylesheet" type="text/css" href="styles.css">
    -->
  </head>
  
  <body>
    <c:forEach items="${emps}"  var="emp">
        ${emp.ename }<br/>
    </c:forEach>
  </body>
</html>

到这一步恭喜，你的ssh项目搭建完了

然后部署项目发布

在浏览器上输入http://localhost:8080/你的项目命/empAction.action就可以访问项目了
