Spring 과 Struts 통합 방식 2

통합 방식 1 을 바탕 으로 개선:

         action   
WebApplicationContext wac = WebApplicationContextUtils.getWebApplicationContext(request.getSession().getServletContext());
 UserDao userDao = (UserDao)wac.getBean("userDao");      
   。

         spring  ，  action   spring     ，      dao    action bean     。
            applicationContext-actions.xml

	<bean name="loginAction" class="com.lwf.spring.web.action.LoginAction">
		<property name="userDao" ref="userDao"></property>
	</bean>
	       struts action,     ，       spring action     
	       ：

	    ActionServlet   struts-config.xml  path， path     ，     spring   action，   spring      name path    。

		</action>
		
		     spring       scope="prototype"            ,       struts              。

	          LoginAction ，    userDao.add(name, pwd);      WebApplicationContext  dao     。

 
설정 이 끝 난 코드 를 보십시오:
action 코드:

package com.lwf.spring.web.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 org.springframework.web.context.WebApplicationContext;
import org.springframework.web.context.support.WebApplicationContextUtils;

import com.lwf.spring.web.dao.UserDao;
import com.lwf.spring.web.form.LoginForm;

public class LoginAction extends Action {

	private UserDao userDao;
	public ActionForward execute(ActionMapping mapping, ActionForm form,
			HttpServletRequest request, HttpServletResponse response)
			throws Exception {
		
		LoginForm loginForm = (LoginForm)form;
		String name = loginForm.getName();
		String pwd = loginForm.getPassword();
		
		userDao.add(name, pwd);
		
		return mapping.findForward("success");
	}
	
	
	public void setUserDao(UserDao userDao) {
		this.userDao = userDao;
	}

}
