這裏我包含了一個用於登錄目的的攔截器類，但是在struts.xml中提到它之後，當我點擊註冊按鈕時，字段錯誤在我的struts表單上不可見我的註冊頁面。
以下是我的struts.xml。請更正我應該放在哪裏LoginInceptors攔截器類。下面是我在struts.xml攔截器不允許在struts2中顯示字段錯誤

下面是我LoginInterceptors類。
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();
}
}
由於攔截總是先執行，表單字段錯誤是不可見的，也不會被重定向到預期的頁面。輸出是「第一次間隔」，然後是剩餘的測試線。
什麼是實際問題？ –
我的方案是：當我點擊註冊按鈕時，（空白）表單被處理，但它沒有給出任何字段錯誤，用戶無法獲得註冊。validate方法被執行，但是因爲攔截器它不會顯示在struts表單上。 –
由於攔截器而隱藏了現場錯誤 –
