<c:forEach />標簽的使用
備注：無法循環打印信息可能的原因：1、引入包改成http://java.sun.com/jsp/jstl/core或者http://java.sun.com/jstl/core；2、jstl包的版本不正確。
一、xhtml代碼
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:c="http://java.sun.com/jsp/jstl/core"> <c:forEach items="#{usersManageImpl.menuManageList}" var="mmList" varStatus="idx">#{mmList.name}或${mmList.name} </c:forEach>
三、java代碼
MenuManageImpl.java 實現類 List<MenuManage> menuManageList = new ArrayList<MenuManage>(); /** * 查詢列表 */ @Override public void getList(ActionEvent event) { menuManageList = dao.getList(); } public List<MenuManage> getMenuManageList() { //menuManageList = dao.getList(); return menuManageList; } public void setMenuManageList(List<MenuManage> menuManageList) { this.menuManageList = menuManageList; } ----------------------------------------------------------------------------------------------------------------------------- MenuManage.java 實體類 private String strMenuName;//菜單名稱 public String getStrMenuName() { return strMenuName; } public void setStrMenuName(String strMenuName) { this.strMenuName = strMenuName; }
四、faces-config.xml
