我正在尝试打开html页面addWunsch.html，但始终会出错。我一直在搜索格式和名称错误，但找不到任何错误。
现在，每当我尝试访问localhost / addWunsch时，我都会收到错误消息
异常：org.springframework.web.util.NestedServletException：请求处理失败；嵌套的异常是org.thymeleaf.exceptions.TemplateInputException：模板解析期间发生错误（模板：“类路径资源[templates / addWunsch.html]”）
状态：500
这是我的addWunsch.html：
<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8">
<title>Wunsch hinzufügen</title>
<link rel="stylesheet" type="text/css" th:href="@{styles.css}"/>
</head>
<body>
<h1>Teile uns deinen Vorschlag mit:</h1>
<form th:action="@{/addWunsch}" th:object="${PizzaWunschForm}" method="POST">
Pizzaname:
<input type="text" th:field="*{pizzaWunschName}" />
<br/>
Pizzabeschreibung:
<input type="text" th:field="*{pizzaWunschBeschreibung}" />
<br/>
<input type="submit" value="Create" />
</form>
<br/>
<!-- Check if errorMessage is not null and not empty -->
<div th:if="${errorMessage}" th:utext="${errorMessage}" style="color:red;font-style:italic;"></div>
</body>
</html>
这是我的控制器：
package de.frauas.projekt.controller;
import java.util.ArrayList;
import java.util.List;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import de.frauas.projekt.form.PizzaWunschForm;
import de.frauas.projekt.model.PizzaWunsch;
@Controller
public class WunschController {
private static List<PizzaWunsch> pizzaWunschListe = new ArrayList<PizzaWunsch>();
@Value("${welcome.message}")
private String message;
@Value("${error.message}")
private String errorMessage;
@RequestMapping(value = { "/wunsch" }, method = RequestMethod.GET)
public String showWunschIndex(Model model) {
model.addAttribute("message", message);
return "wunschIndex";
}
@RequestMapping(value = { "/listWunsch" }, method = RequestMethod.GET)
public String showListWunsch(Model model) {
model.addAttribute("pizzaWunschListe", pizzaWunschListe);
return "listWunsch";
}
@RequestMapping(value = { "/addWunsch" }, method = RequestMethod.GET)
public String showAddWunsch(Model model) {
PizzaWunschForm pizzaWunschForm = new PizzaWunschForm();
model.addAttribute("pizzaWunschForm", pizzaWunschForm);
return "addWunsch";
}
@RequestMapping(value = { "/addWunsch" }, method = RequestMethod.POST)
public String saveWunschPizza(Model model, @ModelAttribute("PizzaWunschForm") PizzaWunschForm pizzaWunschForm) {
String pizzaWunschName = pizzaWunschForm.getPizzaWunschName();
String pizzaWunschBeschreibung = pizzaWunschForm.getPizzaWunschBeschreibung();
if (pizzaWunschName != null && pizzaWunschName.length() > 0 && pizzaWunschBeschreibung != null
&& pizzaWunschBeschreibung.length() > 0) {
PizzaWunsch newPizzaWunsch = new PizzaWunsch(pizzaWunschName, pizzaWunschBeschreibung);
pizzaWunschListe.add(newPizzaWunsch);
return "redirect:/listWunsch";
}
model.addAttribute("errorMessage", errorMessage);
return "addWunsch";
}
}
最佳答案
请更换
<form th:action="@{/addWunsch}" th:object="${PizzaWunschForm}" method="POST">
至
<form th:action="@{/addWunsch}" th:object="${pizzaWunschForm}" method="POST">
...因为您已将 CamelCase键表示的属性添加到
Model中。区分大小写。关于java - 模板解析期间发生错误(模板:“类路径资源[templates/addWunsch.html]”)，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/59704366/
