整合Struts2、Hibernate、Spring

将项目中的对象和对象之间的管理,纳入spring容器,由spring管理

1 实现spring+hibernate集成

1.1 新建web项目

建立项目的包结构(package)

1.2加入jar包

1.3 建立pojo类

package org.guangsoft.pojo;
/***
 * 定部门的pojo类
 * **/
public class Dept
{
    private Integer did;
    private String dname;
    private String ddesc;
    public Integer getDid()
    {
        return did;
    }
    public void setDid(Integer did)
    {
        this.did = did;
    }
    public String getDname()
    {
        return dname;
    }
    public void setDname(String dname)
    {
        this.dname = dname;
    }
    public String getDdesc()
    {
        return ddesc;
    }
    public void setDdesc(String ddesc)
    {
        this.ddesc = ddesc;
    }
}

1.4 建立pojo的映射文件

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC
    "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
    "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
<hibernate-mapping package="com.bjsxt.pojo">
    <!-- 类 到 表 -->
    <class name="Dept" table="t_dept">
        <id name="did" column="did" type="java.lang.Integer">
            <generator class="native"></generator>
        </id>
        <!-- 其他简单属性 -->
        <property name="dname" column="dname" type="java.lang.String"></property>
        <property name="ddesc" column="ddesc" type="java.lang.String"></property>
    </class>
</hibernate-mapping>

1.5建立Dao接口

package org.guangsoft.dao;
import org.guangsoft.pojo.Dept;
/**
 * 部门数据访问接口
 * ***/
public interface DeptDao
{
    public void addDept(Dept dept);
}

1.6建立Dao接口的实现类

package org.guangsoft.dao.impl;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import org.springframework.stereotype.Repository;
import org.guangsoft.dao.DeptDao;
import org.guangsoft.pojo.Dept;
/***
 * 建立dao接口实现类:
 * extends HibernateDaoSupport :
 * 完成在dao类中获得session对象,hibernateTempldate对象
 * ***/
@Repository
public class DeptDaoImpl extends HibernateDaoSupport
implements DeptDao
{
    /***
     * 给父类注入sessionFactory通过自动装配
     * ***/
    // private SessionFactory sessionFactory;
    @Autowired
    public void setSessionFactory01(SessionFactory sessionFactory)
    {
        super.setSessionFactory(sessionFactory);
    }
    @Override
    public void addDept(Dept dept)
    {
        super.getHibernateTemplate().save(dept);
    }
}

1.7建立业务service接口

package org.guangsoft.service;
import org.guangsoft.pojo.Dept;
/**
 * 部门的业务接口
 * ***/
public interface DeptService
{
    public void saveDeptService(Dept dept);
}

1.8 建立service接口实现类

package org.guangsoft.service.impl;
import org.guangsoft.dao.DeptDao;
import org.guangsoft.pojo.Dept;
import org.guangsoft.service.DeptService;
/***
 * 部门业务接口实现类
 * ***/
public class DeptServiceImpl implements DeptService
{
    // 声明dao对象
    private DeptDao deptDao;
    @Override
    public void saveDeptService(Dept dept)
    {
        deptDao.addDept(dept);
    }
}

1.9配置spring容器

1.10 建立测试类

import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class TestApp
{
    @Test
    public void addDept()
    {
        // 加载spring的配置文件,获得bean容器
        ApplicationContext ac = new
        ClassPathXmlApplicationContext("applicationContext.xml");
        // 获得bean对象
        DeptService deptService = (DeptService) ac.getBean("deptServiceImpl");
        // 添加部门
        Dept dept = new Dept();
        dept.setDname("安慰部");
        dept.setDdesc("逗你玩");
        deptService.saveDeptService(dept);
    }
}

2 spring+struts2集成

2.1加入jar

Struts2-spring-plugin.jar

2.2建立Action

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Controller;
import com.opensymphony.xwork2.Action;
import com.opensymphony.xwork2.ModelDriven;
@Controller
@Scope("prototype")
// DeptAction在spring容器中是非单例的
public class DeptAction implements ModelDriven<Dept>
{
    // 自动装配
    @Autowired
    private DeptService deptService;
    // 声明部门对象
    private Dept dept = new Dept();
    @Override
    public Dept getModel()
    {
        return dept;
    }
    /***
     * 处理部门的添加请求
     * **/
    public String addDept()
    {
        deptService.saveDeptService(dept);
        return Action.SUCCESS;
    }
}

2.3进行struts2的配置

<?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="dept" namespace="/" extends="struts-default">
        <!-- class:是Action在spring容器中对应的id -->
        <action name="deptAction_*" class="deptAction" method="{1}">
            <result>/index.jsp</result>
        </action>
    </package>
</struts>

3.4在web.xml中配置

<?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>index.jsp</welcome-file>
    </welcome-file-list>
    <!-- 加载spring的配置文件 -->
    <!-- 配置上下的初始化参数application -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
    </context-param>
    <!--通过监听器加载spring的配置iwenijan -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <!-- 配置open Session in view -->
    <filter>
        <filter-name>osiv</filter-name>
        <filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>osiv</filter-name>
        <url-pattern>*.action</url-pattern>
    </filter-mapping>
    <!-- 配置struts2的核心控制器 -->
    <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>*.action</url-pattern>
    </filter-mapping>
    <filter-mapping>
        <filter-name>struts</filter-name>
        <url-pattern>*.jsp</url-pattern>
    </filter-mapping>
</web-app>

2.5建立UI页面

<%@ 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>
<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">
    </head>
    <body>
        <s:form action="deptAction_addDept.action" method="post" theme="simple">
            <div>
                部门名称:
                <s:textfield name="dname"></s:textfield>
            </div>
            <div>
                部门描述:
                <s:textfield name="ddesc"></s:textfield>
            </div>
            <div>
                <s:submit value="提交"></s:submit>
            </div>
        </s:form>
    </body>
</html>
