如下程序，servlet list 在JSP无法显示？这是为啥？

Question

public List<Project> findAllProject() {// TODO Auto-generated method stubConnection conn = DBConnection.getConnection();String findAllProject = "select * from project"; //SQL语句PreparedStatement pstmt = null; //声明预处理对象ResultSet rs = null;Project project = null;List<Project> Projects = new ArrayList<Project>();try {if(conn==null){System.out.println("conn is null");}else{pstmt = conn.prepareStatement(findAllProject);rs = pstmt.executeQuery(); //执行查询while(rs.next()) {project = new Project();project.setProjectID(rs.getString(1));project.setProjectName(rs.getString(2));project.setApplyDate(rs.getString(3));project.setClientDepart(rs.getString(4));project.setClient(rs.getString(5));project.setProjectDes(rs.getString(6));project.setStartDate(rs.getString(7));project.setEndDate(rs.getString(8));project.setScheme(rs.getString(9));project.setProjectState(rs.getString(10));project.setApplicant(rs.getString(11));project.setTestDepart(rs.getString(12));Projects.add(project);}...return Projects;}JSP<a:forEach items="${requestScope.proAllList}" var="project" ><tr><td>${project.projectID}</td><td>${project.clientDepart}</td><td>${project.projectDes}</td><td>${project.testDepart}</td><td>${project.startDate}</td><td>${project.endDate}</td><td>${project.projectState}</td><td><a href="#" class="btn btn-default">查看详情</a></td></tr></a:forEach>list有数据 size>1

Answer 1

循环标签使用有误，应该是：<c:forEach items="${requestScope.proAllList}" var="project"
></c:forEach>
