struts+spring(2)

 

package prj23_1.action;

 

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

 

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 prj23_1.form.LoginForm;

import dao.IDAO;

 

public class LoginAction extends Action {//默认单态

      

       private IDAO dao;

       public ActionForward execute(ActionMapping mapping, ActionForm form,

                     HttpServletRequest request, HttpServletResponse response) {

              LoginForm loginForm = (LoginForm) form;// TODO Auto-generated method stub

              String account = loginForm.getAccount();

              String password = loginForm.getPassword();

 

              dao.getCusomerByAccount(account);

             

              return new ActionForward("/login.jsp");

       }

      

      

       public IDAO getDao() {

              return dao;

       }

       public void setDao(IDAO dao) {

              this.dao = dao;

       }

}

在action中定义一个接口对象。由接口对象去调 用dao 中方法。

接口对象在spring框架中实例化

 

 

 

applicationContext.xml

 

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

<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">

 

<beans>

    <bean id="dao" class="dao.CustomerDao"></bean>

    <!-- 将dao装配进LoginAction的dao属性

       bean的name和Struts配置文件中action的path相同

       相当于将action的生成完全交给Spring去作

       全权委托

       可以让Action以非单态形式运行，让Action更加灵活

     -->

    <bean name="/login" class="prj23_1.action.LoginAction" singleton="false">

       <property name="dao">

           <ref local="dao"/>

       </property>

    </bean>

</beans>

 

 

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

<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.2//EN" "http://struts.apache.org/dtds/struts-config_1_2.dtd">

 

<struts-config>

  <data-sources />

  <form-beans >

    <form-bean name="loginForm" type="prj23_1.form.LoginForm" />

 

  </form-beans>

 

  <global-exceptions />

  <global-forwards />

  <action-mappings >

  <!-- 将Action的生成在这里截取掉，命令其在Spring框架中生成

    1:让Struts框架认识Spring配置文件:配置插件

    2：用org.springframework.web.struts.DelegatingActionProxy类截获Action的生成

   -->

    <action

      attribute="loginForm"

      input="/login.jsp"

      name="loginForm"

      path="/login"

      scope="request"

      type="org.springframework.web.struts.DelegatingActionProxy" />

 

  </action-mappings>

 

  <message-resources parameter="prj23_1.ApplicationResources" />

 

  <plug-in className="org.springframework.web.struts.ContextLoaderPlugIn">

    <set-property property="contextConfigLocation"

                  value="/WEB-INF/applicationContext.xml" />

  </plug-in> 

</struts-config>

 

 

=======================================

 

不用在web.xml中注册spring框架。

上面的这种方法是最好，最常用的。

 

===========================================

 

还有一种方法。只修改struts配制文件

如下：

Struts-config.xml

 

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

<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.2//EN" "http://struts.apache.org/dtds/struts-config_1_2.dtd">

 

<struts-config>

  <data-sources />

  <form-beans >

    <form-bean name="loginForm" type="prj23_1.form.LoginForm" />

 

  </form-beans>

 

  <global-exceptions />

  <global-forwards />

  <action-mappings >

  <!-- 将Action的生成在这里截取掉，命令其在Spring框架中生成

    1:让Struts框架认识Spring配置文件:配置插件

    2：配置RequestProcessor来截获

   -->

    <action

      attribute="loginForm"

      input="/login.jsp"

      name="loginForm"

      path="/login"

      scope="request"

      type="prj23_1.action.LoginAction" />

 

  </action-mappings>

//增加了这一句

 <controller processorClass="org.springframework.web.struts.DelegatingRequestProcessor"></controller>

 

  <message-resources parameter="prj23_1.ApplicationResources" />

 <plug-in  className="org.springframework.web.struts.ContextLoaderPlugIn">

    <set-property property="contextConfigLocation"

                  value="/WEB-INF/applicationContext.xml" />

  </plug-in> 

</struts-config>
