Question

我正在为Web应用程序创建原型，其中一个功能应允许某人上传带有一些额外信息的excel文件。信息旁边的文件存储在一个对象中，该对象被序列化并存储。

我已经创建了上载方法，并且在尝试测试该功能时，它抛出了“不支持请求方法'POST'”白标签错误页面。

我怀疑可能是pom.xml有问题，但我不确定。

SELECT * FROM Student 
WHERE GraduationDate 
BETWEEN
(CASE
     WHEN (GraduationDate  Is Not Null)
     THEN SELECT convert(datetime, (?) , 121)
     ELSE''
END)
AND
(CASE
     WHEN (GraduationDate  Is Not Null)
     THEN SELECT convert(datetime, (?) , 121)
     ELSE''
END)

这是Controller类。我们将在一两天内迁移到Thymeleaf配置，此html仅用于测试目的。

Answer 1

控制器中的两个方法都带有@GetMapping注释，这意味着它们支持GET请求。您需要用@PostMapping替换一个（以支持POST请求）

Answer 2

从您发布的控制器代码来看，两个端点都是GET。 /老师：-@GetMapping / Teacher / NewTest：-@GetMapping

您正尝试将其发布到不支持POST方法的端点，这就是为什么您看到错误消息，并指定了不支持的'POST'方法。

Answer 3

将您的方法更正为：

@PostMapping
@RequestMapping("/NewTest")
public String newTestUpload(HttpServletRequest request, HttpServletResponse response) {

或

@PostMapping(path = "/NewTest")
public String newTestUpload(HttpServletRequest request, HttpServletResponse response) {

Spring REST控制器文件上传-请求方法'POST'不支持错误
