</beans>这边是loginAction：
/*

 */
package com.yourcompany.struts.action;import javax.servlet.http.HttpServletRequest;

 */
public class LoginAction extends Action {

private hibernatedao hibernatedao;
public void setHibernatedao(hibernatedao hibernatedao) {
this.hibernatedao = hibernatedao;
}
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
LoginForm loginForm = (LoginForm) form;
//hibernateimpl hibernateimpl=new hibernateimpl();
outpl o=new outpl();
o.ou();
Blogadmin ad=new Blogadmin();
System.out.println(loginForm.getPassword());
ad.setPassword(loginForm.getPassword());
ad.setUsername(loginForm.getUsername());
System.out.print(hibernatedao);打印注入进来的类，结果是空的 return null;
}
}
这边是hibernatedao ：
package com.ljj.regit.dao;import com.ljj.regit.newmodel.Blogadmin;public interface hibernatedao {
public void out(Blogadmin ad);
}
这边是实现类：package com.ljj.regit.dao.impl;import org.springframework.orm.hibernate3.support.HibernateDaoSupport;import com.ljj.regit.dao.hibernatedao;
import com.ljj.regit.newmodel.Blogadmin;public class hibernateimpl extends HibernateDaoSupport implements hibernatedao { public void out(Blogadmin ad) {
System.out.print("---------------------------");
//getHibernateTemplate().saveOrUpdate(ad);
}}

Answer 1

struts-config.xml的配置请贴下....

Answer 2

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.3//EN" "http://struts.apache.org/dtds/struts-config_1_3.dtd"><struts-config>

Answer 3

p:sessionFactory-ref="sessionFactory"
   应该是这里的问题把..

Answer 4

type="com.yourcompany.struts.action.LoginAction"这里不在是你指定的类地址了.........你应该使用SPRING的代理为你生成实体对象....改为：type="org.springframework.web.struts.DelegatingActionProxy"<message-resources parameter="com.yourcompany.struts.ApplicationResources" />在此元素下面添加：
<plug-in className="org.springframework.web.struts.ContextLoaderPlugIn">
<set-property property="contextConfigLocation" value="classpath:这里填写你的SPRING配置文件名称" />
</plug-in>

Answer 5

p:sessionFactory-ref="sessionFactory"改为：<property name="hibernatedao" >
     ref="sessionFactory"
</property>去掉：abstract="false" lazy-init="default" autowire="default" dependency-check="default"

Answer 6

<property name="sessionFactory" >上面打错了...

Answer 7

struts-config.xml文件里面的action配置错误，type=org.springframework.web.struts.DelegatingActionProxy
