推荐答案
My controller is
@Controller
public class HouseController {
@Autowired
private HouseService houseService;
@GetMapping(value = "/house")
public ModelAndView get() {
ModelAndView modelAndView = new ModelAndView();
List<HouseDto> listHouse = houseService.listHouse();
modelAndView.addObject("listHouse", listHouse);
modelAndView.setViewName("house/listHouse");
return modelAndView;
}
}
<%@ page contentType="text/html; charset=UTF-8" isELIgnored="false"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%@ page contentType="text/html; charset=UTF-8" isELIgnored="false"%>
###JSP
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html lang="en">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
</head>
<body>
<div>
<c:forEach var="house" items="${listHouse}" varStatus="">
<tr>
<td>${house.name}</td>
</tr>
</c:forEach>
</div>
<body>
#<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
its work for me
