我在尝试在 JSP 页面中使用 JSTL 标记迭代一系列爱好时遇到问题 (
registration-success.jsp目标：
我的JSP页面显示用户提交的注册详细信息，包括他们的爱好。我正在使用
c:forEachhobbiesuserReg错误信息：
java.lang.NoClassDefFoundError: javax/servlet/jsp/tagext/TagLibraryValidator
代码片段：
RegistrationController.java
package com.springmvc.ic.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import com.springmvc.ic.api.UserRegistrationDTO;
@Controller
public class RegistrationController {
@RequestMapping("/register")
public String showRegistrationPage(
@ModelAttribute("userRegistrationInfo") UserRegistrationDTO dto) {
dto.setName("ajay");
return "user-registration-page";
}
@RequestMapping("registration-success")
public String processUserReg(@ModelAttribute("userReg") UserRegistrationDTO dto) {
return "registration-success";
}
}
注册成功.jsp

您缺少 javax.servlet.jsp.tagext.TagLibraryValidator 类。
