10.Spring + Hibernate + Struts 1.x

一.在Spring环境下配置Struts1.x

导入Struts1.x的jar文件：

修改web.xml文件：

<?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"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd
        http://java.sun.com/xml/ns/javaee/jsp " version="2.5">


    <!-- 指定spring的配置文件，默认从web根目录寻找配置文件，我们可以通过spring提供的classpath:前缀指定从类路径下寻找 -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:beans.xml</param-value>
    </context-param>


    <!-- 对Spring容器进行实例化 -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <!-- 使用spring解决struts1.3乱码问题 -->

    <filter>
        <filter-name>encoding</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>encoding</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

    <!-- 使用spring解决hibernate因session关闭导致的延迟加载例外问题 -->
    <filter>
        <filter-name>OpenSessionInViewFilter</filter-name>
        <filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>OpenSessionInViewFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>


    <!-- 配置struts -->
    <servlet>
        <servlet-name>struts</servlet-name>
        <servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
        <init-param>
            <param-name>config</param-name>
            <param-value>/WEB-INF/struts-config.xml</param-value>
        </init-param>
        <load-on-startup>0</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>struts</servlet-name>
        <url-pattern>*.do</url-pattern>
    </servlet-mapping>


</web-app>

以上：

1.对Spring容器进行了配置。

2.对Spring容器进行了实例化。

3.利用Spring的org.springframework.web.context.ContextLoaderListener

  解决Struts1.x的乱码问题。

4.org.springframework.orm.hibernate3.support.OpenSessionInViewFilter

  解决hibernate因session关闭导致的延迟加载例外问题

5.配置struts1.x

WEB-INF下创建struts-config.xml文件：

<?xml version="1.0" encoding="UTF-8" ?>

<!DOCTYPE struts-config PUBLIC
        "-//Apache Software Foundation//DTD Struts Configuration 1.3//EN"
        "http://jakarta.apache.org/struts/dtds/struts-config_1_3.dtd">


<struts-config>


    <form-beans>

        <form-bean name="addPersonForm" type="com.zyy.service.form.AddPersonForm">

        </form-bean>

    </form-beans>

    <global-exceptions>
    </global-exceptions>

    <global-forwards>
    </global-forwards>


    <action-mappings>

        <action path="/persons"
                type="com.zyy.service.action.PersonAction"
                >

            <forward name="list" path="/WEB-INF/jsp/personlist.jsp"></forward>

        </action>

        <action path="/person/add"
                type="com.zyy.service.action.AddPerson"
                parameter="method"
                validate="false"
                scope="request"
                name="addPersonForm">


        </action>

    </action-mappings>

    <!--在struts配置文件中添加进spring的请求控制器
    该请法语控制器会先根据action的path属性值到spring
    容器中寻找跟该属性值同名的bean。如果寻找到即使用该bean处理用户请求
    -->

    <controller>
        <set-property property="processorClass" value="org.springframework.web.struts.DelegatingRequestProcessor"/>
    </controller>


    <message-resources parameter="resource.MessageResources"/>


</struts-config>

以上：

在Struts配置中添加了Spring 的请求控制器:该请法语控制器会先根据action的path属性值

到spring容器中寻找跟该属性值同名的bean。如果寻找到即使用该bean处理用户请求

Spring的beans.xml文件不需要修改。

由于Struts配置文件的需要，在com.zyy.service.form路径下，建立一个

AddPersonForm：

package com.zyy.service.form;

import org.apache.struts.action.ActionForm;

/**
 * Created by CaMnter on 2014/8/26.
 */
public class AddPersonForm extends ActionForm {

    private Integer id;

    private String name;

    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;
    }
}

com.zyy.service.action路径下，建立AddPerson 和 PersonAction：

PersonAction

package com.zyy.service.action;

import com.zyy.service.PersonService;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

/**
 * Created by CaMnter on 2014/8/24.
 */

/**
 * struts 的Action  交给Spring管理
 * bean的名字和action 中 path 必须一致
 */


@Service("/persons")
public class PersonAction extends Action {

    @Autowired
    private PersonService personService;

    public ActionForward execute(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception {
/*

        WebApplicationContext webApplicationContext = WebApplicationContextUtils
                .getWebApplicationContext(this.getServlet().getServletContext());


        this.personService = (PersonService) webApplicationContext.getBean("personServiceBean");
*/
        request.setAttribute("persons", this.personService.getPersons());


        return mapping.findForward("list");
    }
}

这个Action要交给Spring容器管理的话，那么使用注解和自动扫描对这个action的bean

命名 必须和 Struts配置文件中action 的path一致对应(<action path="/persons"  

type="com.zyy.service.action.PersonAction" >)，所以这些定义的注解是

Service("/persons")。

AddPerson

package com.zyy.service.action;

import com.zyy.service.PersonService;
import com.zyy.service.form.AddPersonForm;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.actions.DispatchAction;
import org.springframework.beans.factory.annotation.Autowired;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

/**
 * Created by CaMnter on 2014/8/26.
 */
public class AddPerson extends DispatchAction {

    @Autowired
    private PersonService personService;

    public ActionForward add(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception {

        AddPersonForm addPersonForm = (AddPersonForm) form;

        System.out.println(addPersonForm.getName());

        //this.personService.save(new Person(addPersonForm.getName()));

        request.setAttribute("message", "添加成功");

        return null;
    }
}

然后在WEN-INF下，创建JSP文件夹 再创建 message.jsp 、 personlist.jsp

和 WEB根目录下的 struts_submit.jsp：

personlist.jsp

        <input type="submit" value="提交">

二.测试

输入http://127.0.0.1:8080/SSH/persons.do：

在WEB跟目录下找到：
