是什么原因导致“ HTTP方法名称必须是令牌”错误？

如何解决是什么原因导致“ HTTP方法名称必须是令牌”错误？

我根本无法再访问我的spring Web应用程序的url，因为它总是抛出此错误：

我尝试清理浏览器历史记录和cookie（使用不同的浏览器），尝试使用http而不是https来访问它，并尝试运行多个不同的项目（过去曾经工作过））。我不知道我还能尝试解决什么错误。

可能是什么原因造成的？

控制器：

@Controller
public class ProductController {

@Autowired
private ProductService productService;

@Autowired
public ProductController(ProductService productService) {
    this.productService = productService;
}

@GetMapping("/products")
public ModelAndView products() {
    ModelAndView mv = new ModelAndView();

    List<Product> productList = (List<Product>) productService.getAllProducts();

    mv.addobject("activeTabProducts",true);
    mv.addobject("productList",productList);

    return mv;
}

}

解决方法

我不知道为什么，但是当我尝试从匿名标签访问它时，它起作用了
