未使用路径变量和 http 请求作为参数调用 Spring Rest Controller 方法答案

【问题标题】：Spring Rest Controller method not invoked with path variable and http request as arguments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
      }
}

application.properties

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

所以当我向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？

【问题讨论】：

您能否添加更多信息，例如您用于控制器的注释或您要返回什么？
在类中添加@RequestMapping("/myproject")
@trjade 我已经更新了我的帖子。我已将我的控制器注释为休息控制器。
您还有其他方法具有相同的 url 但具有 POST 映射吗？请添加完整的控制器代码。
@ViswanathLekshmanan 我已经在 application.properties 中指定了上下文路径

【解决方案1】：

这是您定义的路径：

/quiz/{quizId}/identifyfromsixjson

这是您正在测试的路径

/identifyfromsixjson/test

显然它们不匹配，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。更新您的路径定义

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

然后测试

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

【解决方案2】：

看起来你想写一个 RestController。用@RestController注释你的控制器

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

【讨论】：

注解为Restcontroller。我已经更新了我的帖子。
@Kartik 请检查问题中的详细信息是否正确。您的端点不同，您正在使用不同的 URL 进行测试。
