SSH整合案列

问题

使用Spring整合Hibernate及Struts2，实现资费查询功能。

 

方案

SSH整合步骤

 

步骤

实现此案例需要按照如下步骤进行。

步骤一：导包

创建WEB项目NETCTOSS-SSH，并导入数据库驱动包、Struts2开发包、Hibernate开发包以及Spring开发包，完成后项目中包结构如下图

 

注意，Hibernate开发包中的freemarker.jar，与Struts2中的包重复，且版本较低，去掉。Spring开发包中的commons-logging.jar，与Hibernate中的包重复，且版本较低，去掉。

步骤二：使用Spring整合Hibernate

在src根路径下引入并配置applicationContext.xml，并在该文件中配置数据源、SessionFactory、开启组件扫描以及声明式事务，代码如下

在com.tarena.entity包下创建实体类Cost，代码如下

package com.tarena.entity;
import java.sql.Date;
/**
 * 资费实体类
 */
public class Cost {
    private Integer id;// 主键
    private String name;// 资费名称
    private Integer baseDuration;// 在线时长
    private Double baseCost;// 基本费用
    private Double unitCost;// 单位费用
    private String status;// 状态
    private String descr;// 资费说明
    private Date createTime;// 创建日期
    private Date startTime;// 启用日期
    private String costType;// 资费类型
    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 Integer getBaseDuration() {
        return baseDuration;
    }
    public void setBaseDuration(Integer baseDuration) {
        this.baseDuration = baseDuration;
    }
    public Double getBaseCost() {
        return baseCost;
    }
    public void setBaseCost(Double baseCost) {
        this.baseCost = baseCost;
    }
    public Double getUnitCost() {
        return unitCost;
    }
    public void setUnitCost(Double unitCost) {
        this.unitCost = unitCost;
    }
    public String getStatus() {
        return status;
    }
    public void setStatus(String status) {
        this.status = status;
    }
    public String getDescr() {
        return descr;
    }
    public void setDescr(String descr) {
        this.descr = descr;
    }
    public Date getCreateTime() {
        return createTime;
    }
    public Date getStartTime() {
        return startTime;
    }
    public void setStartTime(Date startTime) {
        this.startTime = startTime;
    }
    public void setCreateTime(Date createTime) {
        this.createTime = createTime;
    }
    public String getCostType() {
        return costType;
    }
    public void setCostType(String costType) {
        this.costType = costType;
    }
}

在com.tarena.entity包下创建映射关系文件Cost.hbm.xml，代码如下

<?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>
    <class name="com.tarena.entity.Cost" table="cost">
        <id name="id" type="integer" column="id">
            <!-- 用来指明主键的生成方式 -->
            <generator class="sequence">
                <param name="sequence">cost_seq</param>
            </generator>
        </id>
        
        <property name="name" 
            type="string" column="name" />
        <property name="baseDuration" 
            type="integer" column="base_duration" />
        <property name="baseCost" 
            type="double" column="base_cost" />
        <property name="unitCost" 
            type="double" column="unit_cost" />
        <property name="status" 
            type="string" column="status" />
        <property name="descr" 
            type="string" column="descr" />
        <property name="createTime" 
            type="date" column="creatime" />
        <property name="startTime" 
            type="date" column="startime" />
        <property name="costType" 
            type="string" column="cost_type" />
    </class>
</hibernate-mapping>

在com.tarena.dao包下创建DAO接口ICostDao，并在接口中声明查询全部资费数据的方法，代码如下

package com.tarena.dao;
import java.util.List;
import com.tarena.entity.Cost;
public interface ICostDao {
    List<Cost> findAll();
}

在com.tarena.dao包下创建DAO实现类CostDaoImpl，继承于HibernateDaoSupport，并实现接口ICostDao，代码如下

package com.tarena.dao;
import java.util.List;
import javax.annotation.Resource;
import org.hibernate.SessionFactory;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import org.springframework.stereotype.Repository;
import com.tarena.entity.Cost;
@Repository
public class CostDaoImpl 
    extends HibernateDaoSupport implements ICostDao {
    @Resource
    public void setSF(SessionFactory sf) {
        super.setSessionFactory(sf);
    }
    @Override
    public List<Cost> findAll() {
        String hql = "from Cost";
        return getHibernateTemplate().find(hql);
    }
}

步骤三：使用Spring整合Struts2

配置web.xml，配置一个listener，使tomcat启动时自动加载Spring。另外再配置Struts2的前端控制器，代码如下

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5">
  <display-name></display-name>
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
  
  <!-- 配置listener，使tomcat启动时自动加载Spring -->
  <listener>
    <listener-class>
          org.springframework.web.context.ContextLoaderListener
      </listener-class>
  </listener>
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
  </context-param>
  
  <!-- 配置前端控制器 -->
  <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>

在com.tarena.action包下创建Action类FindCostAction，调用DAO实现对资费的查询，代码如下

package com.tarena.action;
import java.util.List;
import javax.annotation.Resource;
import org.springframework.stereotype.Controller;
import com.tarena.dao.ICostDao;
import com.tarena.entity.Cost;
@Controller
@Scope("prototype")
public class FindCostAction {
    @Resource
    private ICostDao costDao;
    private List<Cost> costs;
    public String load() {
        costs = costDao.findAll();
        return "success";
    }
    public List<Cost> getCosts() {
        return costs;
    }
    public void setCosts(List<Cost> costs) {
        this.costs = costs;
    }
}

在src根路径下引入struts.xml并配置Action，代码如下

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.1.7//EN"
    "http://struts.apache.org/dtds/struts-2.1.7.dtd">
<struts>
    
    <package name="cost" 
        namespace="/cost" extends="json-default">
        <action name="findCost" 
            class="findCostAction" method="load">
            <result name="success">
                /WEB-INF/cost/find_cost.jsp
            </result>
        </action>
    </package>
</struts>

在WEB-INF/cost下创建页面find_cost.jsp，实现资费数据的显示，代码如下

<%@page pageEncoding="utf-8" isELIgnored="false"%>
<%@taglib uri="/struts-tags" prefix="s"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

        <script language="javascript" type="text/javascript">
            //排序按钮的点击事件
            function sort(btnObj) {
                if (btnObj.className == "sort_desc")
                    btnObj.className = "sort_asc";
                else
                    btnObj.className = "sort_desc";
            }
            //启用
            function startFee() {
                var r = window.confirm("确定要启用此资费吗？资费启用后将不能修改和删除。");
                document.getElementById("operate_result_info").style.display = "block";
            }
            //删除
            function deleteFee() {
                var r = window.confirm("确定要删除此资费吗？");
                document.getElementById("operate_result_info").style.display = "block";            }
        </script>        
    </head>

                    1、创建资费时，状态为暂停，记载创建时间；<br />
                    2、暂停状态下，可修改，可删除；<br />
                    3、开通后，记载开通时间，且开通后不能修改、不能再停用、也不能删除；<br />
                    4、业务账号修改资费时，在下月底统一触发，修改其关联的资费ID（此触发动作由程序处理）
