大家好我是Spring的新手请解决我的问题我得到bean创建异常这里是我的代码（我在动态Web项目中创建了这些）我正在尝试做一个简单的Springmvc项目。

文件名：login.Jsp 

<form action="login.do" method="post">
username<input type="text" name="username"/>
password<input type="password" name="password"/>
<input type="submit" value="login"/>
</form>

        </props>
        </property>
        </bean>
        <bean id="id2" class="logincontroller"/>
</beans>

文件名：logincontroller.java 

package springmvc;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;

public class logincontroller implements Controller {

    @Override
    public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) throws Exception {

        String username = request.getParameter("username");
        String password = request.getParameter("password");
        loginaction action = new loginaction();
        String result = action.verifyuser(username,password);
        if(result.equals("success"))
        return new ModelAndView("success.jsp");
        else
            return new ModelAndView("failure.jsp");


    }

}

filename：success.jsp 

<% out.println("login success");%>

文件名：failure.jsp 

<% out.println("failed");%>

在我运行login.jsp并输入用户名为“admin”密码为“admin”后，我收到此错误

1 个答案:

答案 0 :(得分：1)

<bean id="id2" class="logincontroller"/>

此行导致此问题。

您需要在class属性中提及完全限定的类名。像这样的东西。

 <bean id="id2" class="X.logincontroller"/>

其中X是您的完全限定包名。
