Struts+Spring+Hibernate有异常,急

[bingbox_1984]

LoginAction.java文件如下:
/*
* Generated by MyEclipse Struts
* Template path: templates/java/JavaClass.vtl
*/
package 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 web.form.LoginForm;
import service.LoginService;
import vo.User;
public class LoginAction extends Action {
private LoginService loginservice;

public ActionForward execute(ActionMapping mapping, ActionForm form,HttpServletRequest request,HttpServletResponse response) {
LoginForm loginForm = (LoginForm) form;
User user=new User();
user.setUserName(loginForm.getUsername());
user.setPassword(loginForm.getPassword());
if (loginservice.isValid(user))
return mapping.findForward("success");
else
return mapping.findForward("fail");
}

public LoginService getLoginservice() {
return loginservice;
}

public void setLoginservice(LoginService loginservice) {
this.loginservice = loginservice;
}

}

struts-config.xml文件如下:

LoginService文件如下:

package service;
import java.util.List;
import dao.UserDAO;
import vo.User;
public class LoginService {
private UserDAO userdao;
public UserDAO getUserdao() {
return userdao;
}
public void setUserdao(UserDAO userdao) {
this.userdao = userdao;
}
public boolean isValid(User user) {//判断用户是否合法
List result = userdao.findByExample(user);
if (result.size() > 0)
return true;
else
return false;
}
}

异常如下:javax.servlet.ServletException: Error creating bean with name '/login' defined in ServletContext resource [/WEB-INF/classes/applicationContext.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'loginservice' of bean class [web.action.LoginAction]: Bean property 'loginservice' is not writable or has an invalid setter method: Does the parameter type of the setter match the return type of the getter?

由于一个ID最多只能连续回复三次
所以希望UP

我baidu了好久,找不到答案

[li_d_s]

晕，贴了一大堆没用的，很明显applicationContext.xml里面定义的类web.action.LoginAction没有setLoginservice这个方法，估计是你大小写的问题，应该是loginService?

[bingbox_1984]

改了也没用啊
还是同样的问题

[bruni]

你的LoginAction中没有对应的loginservice set 方法
建一个setLoginservice()方法就可以了
