spring-boot - Thymleaf -> 执行处理器“org.thymeleaf.spring5.processor.SpringInputGeneralFieldTagProcessor”时出错
问题描述
我正在尝试获取 add-journeyFooOrder 视图并且无法执行（获取视图说 - Whitelabel Error Page）所以请帮助我，让我知道我在这里做错了什么以及为什么。提前致谢
所以当我第一次点击localhost:8080时，我可以从那里获取index.html我点击链接添加订单然后我应该被重定向到我收到错误的add-journeyFoodOrder.html视图（请查看控制器代码这将更加清晰）。错误日志如下：
org.thymeleaf.exceptions.TemplateProcessingException：在 org.thymeleaf.processor.element.AbstractAttributeTagProcessor

解决方案
您需要添加您引用的对象th:object：
<form action="#" th:action="@{/addJourneyFoodOrder}" th:object="${journeyFoodOrder}" method="post">
我看到您提到它，但在 GET 映射中没有添加此模型属性。从您的 GET 映射中添加它，它应该可以正常工作。
乐：
您也可以使用此变体：
@GetMapping("/signup") public String showSignUpForm(JourneyFoodOrder journeyFoodOrder) { return "add-journeyFoodOrder"; }
