Question

我的java代码是

@RequestMapping(value = "/common_views/view-lecturer-Projects")
    public String viewLecturerProjects(HttpServletRequest request, ModelMap map) {
        String userId=request.getParameter("userId");
        map.put("viewUserProjects", projectService.findProjectByUserId(Long.valueOf(userId)));
        System.out.println("=================>Project type= "+projectService.findProjectByUserId(Long.valueOf(userId)).getTypeOfProject());
        System.out.println("=================>Project title= "+projectService.findProjectByUserId(Long.valueOf(userId)).getTitleOfProject());
       // System.out.println("===============>Project= "+(projectService.findProjectByUserId(Long.valueOf(userId))).get(0).getTitleOfProject());
        return "common_views/viewLecturerProjects";
    }

页面/ common_views / view-讲师 - 项目是

</body>

在此页面中，$ {viewUserProject.titleOfProject}，$ {viewUserProject.typeOfProject}`在此页面中不显示，但java代码打印值

Answer 1

在jsp上编写以下taglib import语句。

<%@ taglib prefix="c" 
       uri="http://java.sun.com/jsp/jstl/core" %>

如果您没有JARL用于JSTL，请从下面的URL下载并将该JAR放入项目的构建路径中。

<c：foreach>标记无法正常工作</c：foreach>
