使用DispatchAction的代码:
package hb;

import java.util.List;

import org.apache.struts.action.Action;
import org.apache.struts.actions.DispatchAction;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;

import org.apache.struts.action.ActionMessages;
import org.apache.struts.action.ActionMessage;


import javax.servlet.ServletContext;
import javax.sql.DataSource;
import javax.servlet.http.*;


public final class LoginAction extends DispatchAction { 
     
    public ActionForward login(ActionMapping mapping, 
                              ActionForm form, 
                              HttpServletRequest request, 
                              HttpServletResponse response) 
    throws Exception { 
              
        UserForm userform = (UserForm) form;         
		String name = userform.getName();
		
		if(UserDAO.chkUserName(name)>0){

 	   			 return (mapping.findForward("successed"));//登陆成功				
		  }
        else{return mapping.findForward("failed");}   

    } 
    
    public ActionForward addUser(ActionMapping mapping, 
                              ActionForm form, 
                              HttpServletRequest request, 
                              HttpServletResponse response) 
    throws Exception { 
              
        UserForm userform = (UserForm) form;         
		String name = userform.getName();
		
		UserDAO userDao=new UserDAO();
		         userDao.saveName(name);

 	   			 return (mapping.findForward("successed"));			  

    } 
    
    public ActionForward getUser(ActionMapping mapping, 
                              ActionForm form, 
                              HttpServletRequest request, 
                              HttpServletResponse response) 
    throws Exception { 
    
        HttpSession session = request.getSession(true);      
        UserForm userform = (UserForm) form;         
		String name = userform.getName();
		List list=null;
		
		UserDAO userDao=new UserDAO();
		
		list=userDao.getGbooks();
	    session.setAttribute("userList",list);

 	   			 return (mapping.findForward("successed"));			  

    } 

}
LoginActionstruts-config.xml中的部署:
<action-mappings>
		<action path="/login" type="hb.LoginAction" name="formBean1" scope="request" validate="false"  input="/error.jsp" parameter="method"/>
        <action path="/regist" forward="/addUser.jsp"/> 
login.jsp相关代码:
<form action=login.do?method=addUser method="post">
<bean:message key="item.username"/>
<input size="15" name="name">addUser<p>
<html:submit>
	 	<bean:message key="item.submit"/>
	</html:submit>
</form>
<a href ="login.do?method=getUser">getUser</a>
