从 Tomcat 服务器 Conf 请求方法切换到 Spring Boot 后 'POST' 不支持
After switching to SpringBoot from TomcatServerConf Request method 'POST' not supported
最初，我使用 IntelliJ Idea Tomcat 本地服务器配置启动项目（一切正常），但决定使用 Spring 启动应用程序。我添加了主class，更改了pom.xml（删除spring-context并添加spring-boot-starter-parent，spring-boot，spring-boot-starter-tomcat, spring-boot-starter-web, spring-boot-autoconfigure), 在该应用程序运行后，GET-Method 有效，但是 POST - 不支持。请帮帮我！！！谢谢！

控制器
@RequestMapping("/categories")
@Controller
public class CategoriesController {
private CategoriesDao categoriesDAO;
@Autowired
public void setCategoriesDAO(CategoriesDao categoriesDAO)
{
this.categoriesDAO = categoriesDAO;

@GetMapping

public String updateCategory(@ModelAttribute("editCategory") Category updateCategory,

要在主 class 中实现配置方法，您可以这样做：
@SpringBootApplication
public class Main extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(Main.class, args);
}
@Override
protected SpringApplicationBuilder configure(
SpringApplicationBuilder builder) {
return builder.sources(Main.class);
}
}
我认为这些依赖项应该足够了（假设您使用的是 Thymeleaf）：
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.4.3</version>
<relativePath/>

编辑：您的 ModelAttribute 'Category' 可能无法成功解析。要么映射失败，要么验证失败？您可能会通过添加错误处理程序 and/or 调试会话来找到答案。
其他想法：使用@RestController 代替@Controller。尝试使请求映射更明确。不是在 class 上，而是在每个方法上放一个：
@RequestMapping(value = "/categories", produces = "application/json", method=RequestMethod.GET)
public String index(Model model) {
...
@RequestMapping(value = "/categories", produces = "application/json", method=RequestMethod.POST)
public String addCategory(@ModelAttribute("category") @Valid Category category,
BindingResult bindingResult, Model model) {

谢谢大家！我在我的问题上找到了答案。这是 HiddenHttpMethodFilter 的一些问题。我刚刚在我的 Spring 配置中添加了这段代码，额外的依赖项是 .它开始工作了！！！
