从Spring Boot 2.1.6.RELEASE升级到2.2.0.RELEASE后,在嵌入式Tomcat上执行放置和删除操作时,基于Thymeleaf的页面失败了。获取和发布工作正常。
我在Chrome开发人员工具中看到正在发送以下请求:
请求网址:https://localhost:8443/notifications/1 请求方法:POST
请求正文包含_method =“ put”和_csrf令牌。
有趣的是,以@SpringBootTest注释的集成测试正在通过。
Spring Boot Actuator显示/ notifications / {notificationId}已映射到PUT。
切换回2.1.6.RELEASE解决了该问题。
我的Thymeleaf表单定义如下:
<form id="notificationForm" th:action="@{/notifications/{notificationId}(notificationId=${notification.id})}" th:object="${notification}" th:method="put" class="needs-validation" novalidate autocomplete="off">
我的控制器方法的注释如下:
@PutMapping("/notifications/{notificationId}")
public String updateNotification(@PathVariable("notificationId") final Long notificationId,
@Valid @ModelAttribute(name = NOTIFICATION_MODEL_ATTRIBUTE) final NotificationDto notificationDto,
final BindingResult result, final Model model, final RedirectAttributes attributes)
执行删除操作时,控制台中将显示以下堆栈跟踪:

It's as though Spring is not performing the necessary method conversion using _method before resolving the mapping.
Does anyone have any ideas?
答案 0 :(得分:2)
好像Spring在解决映射之前没有使用_method执行必要的方法转换。
这正是正在发生的事情。此转换由HiddenHttpMethodFilter
执行,它是disabled by default in Spring Boot 2.2:
处理
_method
请求参数的过滤器现在默认情况下处于禁用状态,因为如果请求正文可能包含参数,则会导致请求主体的早期消耗。可以通过将spring.webflux.hiddenmethod.filter.enabled
或spring.mvc.hiddenmethod.filter.enabled
设置为true来恢复。
您正在使用Spring MVC,因此应设置spring.mvc.hiddenmethod.filter.enabled=true
。
