Spring Rest 控制器方法未以路径变量和 http 请求作为参数调用

Question

这是我的控制器方法

@RestController
public class ProfileController {
@GetMapping("/quiz/{quizId}/identifyfromsixjson")
@ResponseBody
UserProfileQuestion playIdentifyFromSix(@PathVariable String quizId, HttpServletRequest request) {
... Calling service method  ... here
}
}

应用程序属性

server.contextPath=/myproject
spring.h2.console.enabled=true
spring.jpa.hibernate.ddl-auto=update

因此，当我向 http://localhost:8080/myproject/identifyfromsixjson/test 发出GET请求时，这是我在Postman中看到的响应。

{
"timestamp": "2018-10-08T02:42:14.387+0000",
"status": 405,
"error": "Method Not Allowed",
"message": "Request method 'GET' not supported",
"path": "/myproject/quiz/test/identifyfromsixjson"
}

我做错了什么？

Answer 1

这是您定义的路径：

/quiz/{quizId}/identifyfromsixjson

这就是您正在测试的路径

/identifyfromsixjson/test

很明显，它们不匹配，这就是您收到该错误的原因。

您可以执行以下操作：

1. 使用您定义的路径进行测试：

http://localhost:8080/myproject/quiz/test/identifyfromsixjson

2. 更新路径定义

@GetMapping("/identifyfromsixjson/{quizId}")
@ResponseBody
UserProfileQuestion playIdentifyFromSix(@PathVariable String quizId,HttpServletRequest request) {
... Calling service method  ... here
}

然后使用

http://localhost:8080/myproject/identifyfromsixjson/test

Answer 2

看起来你想写一个 RestController。使用@RestController注释控制器

@RestController
public class QuizController {
@GetMapping("/identifyfromsixjson/{quizId}")
@ResponseBody
UserProfileQuestion playIdentifyFromSix(@PathVariable String quizId, HttpServletRequest request) {
... Calling service method  ... here
}
}
