taglib遍历foreach循环list集合

第一部导入jstl.jar

第二步进行list传输：

package com.aaa.servlet;



import com.aaa.dao.IUserDAO;
import com.aaa.dao.impl.UserDAOImpl;

import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.List;
import java.util.Map;
@WebServlet("/test")
public class IsLoginServlets extends HttpServlet {

    @Override
    protected void service(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        req.setCharacterEncoding("UTF-8");

        IUserDAO userDAO = new UserDAOImpl();
        List<Map<String, Object>> selectAllAdmin = userDAO.selectAllAdmin();

        req.setAttribute("list",selectAllAdmin);
        req.getRequestDispatcher("/indexs.jsp").forward(req,resp);
    }
}

第三步测试：
