三、ejb與spring struts整合

1、spring管理jndi的尋找

<bean id="userManager" class="org.springframework.jndi.JndiObjectFactoryBean"><property name="jndiName" value="userManager/local"></property></bean>

2、開發struts actionFor和action

public class UserForm extends ActionForm{private String username;private String password;//getter setter 方法}public class UserAction extends Action {private UserManagerLocal userManager;public UserManagerLocal getUserManager() {return userManager;}public void setUserManager(UserManagerLocal userManager) {this.userManager = userManager;}@Overridepublic ActionForward execute(ActionMapping mapping, ActionForm form,HttpServletRequest request, HttpServletResponse response)throws Exception {UserForm userForm = (UserForm)form;User user = new User();user.setUsername(userForm.getUsername());user.setPassword(userForm.getPassword());userManager.addUser(user);return mapping.findForward("add_success");}}

3、配置struts設定檔

<?xml version="1.0" encoding="ISO-8859-1" ?><!DOCTYPE struts-config PUBLIC          "-//Apache Software Foundation//DTD Struts Configuration 1.2//EN"          "http://jakarta.apache.org/struts/dtds/struts-config_1_2.dtd"><struts-config>    <form-beans>            <form-bean            name="userForm"            type="com.dcy.ejb.web.forms.UserForm">                   </form-bean>    </form-beans>    <action-mappings>        <action            path="/user_add"            type="org.springframework.web.struts.DelegatingActionProxy"            name="userForm"            scope="request">                  <forward name="add_success" path="/success.jsp"></forward>            </action>    </action-mappings> <message-resources parameter="MessageResources" /></struts-config>

4、spring管理action的建立

<bean name="/user_add" class="com.dcy.ejb.web.action.UserAction" scope="prototype"><property name="userManager" ref="userManager"></property></bean>

5、配置web.xml設定檔

<servlet>    <servlet-name>action</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>    <init-param>      <param-name>debug</param-name>      <param-value>2</param-value>    </init-param>    <init-param>      <param-name>detail</param-name>      <param-value>2</param-value>    </init-param>    <load-on-startup>2</load-on-startup>  </servlet>  <!-- Standard Action Servlet Mapping -->  <servlet-mapping>    <servlet-name>action</servlet-name>    <url-pattern>*.do</url-pattern>  </servlet-mapping>    <context-param>    <param-name>contextConfigLocation</param-name>    <param-value>/WEB-INF/applicationContext*.xml,classpath*:applicationContext-*.xml</param-value>    </context-param><listener>        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>    </listener>    <welcome-file-list>    <welcome-file>index.jsp</welcome-file>  </welcome-file-list>

6、jsp頁面

<body>    This is my JSP page. <br>    <form action="user_add.do" method="post">    <input type="text" name="username"/>    <input type="text" name="password"/>    <input type="submit" value="ti jiao"/>    </form>  </body>
