三、ejb与spring struts集成
1、spring管理jndi的查找
[java] view plaincopy
<bean id="userManager" class="org.springframework.jndi.JndiObjectFactoryBean">
        <property name="jndiName" value="userManager/local"></property>
    </bean>
2、开发struts actionFor和action
[java] view plaincopy
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;
    }

    @Override
    public 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配置文件
[html] view plaincopy
<?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的创建
[html] view plaincopy
<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配置文件
[html] view plaincopy
<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>


<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页面
[html] view plaincopy
<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>
