1、在jsp页面引入
<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
2、遍历的语法：
<c:forEach items="接收集合对象" var="迭代参数名称" varStatus="迭代状态，可访问迭代自身信息">
注意：items的值是要带花括号的，它是通过EL表达式拿值的
3、举例
controller代码
@RequestMapping(value = "/getalltrashcanarticle")
public String getAllTrashCanArticle(HttpSession session,HttpServletRequest request,Model model){
SearchInfo searchInfo = new SearchInfo();
//UserVo user = (UserVo) session.getAttribute("user");
UserVo user = new UserVo();
user.setId(1);
user.setUserRight(1);
searchInfo.setPageId(1);
searchInfo.setSearchInfo("我");
searchInfo.setUser(user);
JsonResult jsonResult = articleAllService.findAllTrashCanArticle(searchInfo);
if (null != jsonResult) {
model.addAttribute("article",jsonResult.getObj());
System.out.println("111111111111"+jsonResult.getObj());
return "showArticle";
}
//request.setAttribute("error", "没有找到该角色");
model.addAttribute("error", "没有找到回收站文章");
return "error";
}jsp代码
