spring-mvc - 未使用路径变量和 http 请求作为参数调用 Spring Rest Controller 方法

问题描述

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"
}

我究竟做错了什么？

解决方案

这是您定义的路径：

/quiz/{quizId}/identifyfromsixjson

这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. 更新你的路径定义

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

然后用

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