这里我包含了一个用于登录目的的拦截器类，但是在struts.xml中提到它之后，当我点击注册按钮时，字段错误在我的struts表单上不可见我的注册页面。
以下是我的struts.xml。请更正我应该放在哪里LoginInceptors拦截器类。下面是我在struts.xml拦截器不允许在struts2中显示字段错误

下面是我LoginInterceptors类。
package org.entity;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
import org.apache.struts2.ServletActionContext;
import com.opensymphony.xwork2.ActionInvocation;
import com.opensymphony.xwork2.interceptor.Interceptor;
public class LoginInterceptors implements Interceptor
{
@Override
public void destroy() {
// TODO Auto-generated method stub
}
@Override
public void init() {
// TODO Auto-generated method stub
}
@Override
public String intercept(ActionInvocation action) throws Exception {
HttpSession session=ServletActionContext.getRequest().getSession(false);
if(session==null || session.getAttribute("login")==null)
{
ServletActionContext.getResponse().sendRedirect("BloodBankSection.jsp");
System.out.println("First Inter");
}
return action.invoke();
}
}
由于拦截总是先执行，表单字段错误是不可见的，也不会被重定向到预期的页面。输出是“第一次间隔”，然后是剩余的测试线。
什么是实际问题？ –
我的方案是：当我点击注册按钮时，（空白）表单被处理，但它没有给出任何字段错误，用户无法获得注册。validate方法被执行，但是因为拦截器它不会显示在struts表单上。 –
由于拦截器而隐藏了现场错误 –
