Spring启动应用程序Post方法调用，405：方法不允许

Question

我正在用Spring启动编写Rest Application。 将我的服务代码公开为REST服务。

当我使用下面的Controller和Pojo类代码编写Post方法时，我能够在GET方法中公开我的服务。我得到405：Method Not Allowed错误。 不明白为什么？

我已经提到了这个链接。 和其他人有关，但我无法弄清楚问题是什么。

下面是我的控制器和Pojo与杰克逊Json注释的代码。

当我使用高级REST客户端 - Chrome网上应用店 - 谷歌进行呼叫并使用附加图像时，我得到以下错误。

在同一个类我有一些工作正常的GET方法。 错误：URL： http://localhost:8085/DBService/application/saveApplicationAnswer

{
"timestamp": 1470313096237
"status": 405
"error": "Method Not Allowed"
"exception": "org.springframework.web.HttpRequestMethodNotSupportedException"
"message": "Request method 'POST' not supported"
"path": "/DBService/application/saveApplicationAnswer"
}

DBService是我的上下文名称

因为我在application.properties设置了server.context-path=/DBService

import java.io.Serializable;
import java.util.List;

    @RequestMapping(value = "/saveApplicationAnswer", method = RequestMethod.POST, consumes = MediaType.APPLICATION_JSON_VALUE, produces = MediaType.APPLICATION_JSON_VALUE)
    public int saveApplicationAnswer(@ModelAttribute(ServicesConstants.SURVERY_ANSWER_FL) ApplicationAnswerDTO applicationAnswer) {

        LOG.info("ApplicationDBController fn saveApplicationAnswer BookingId {} {} {}",applicationAnswer.getBookingId(),  ServicesConstants.CUSTOMER_ID_FL, applicationAnswer.getCustomerId());
        return applicationDBService.saveapplicationAnswer(applicationAnswer);
    }

}

我的JSON：

{"answerId":1,"applicationQuestionId":1,"recommendId":1,"bookingId":123001,"customerId":19501,"reasonForCancelation":"I dont konw ","feedbackText":"I dont know what is this too bad design","applicationDate":"2016-08-04","funnelPageName":"I dont know what is the use of this.","applicationReferenceSource":"I dont knwo what is this field for","languageId":1}

我的Pojo用JSON注释：

提前感谢您提供任何信息和建议。

Answer 1

Can you check the method type which your are requesting.
In the screen shot which your shared it is displaying only get and head method are allowed.
I have tried your code in my Soap ui. It is displaying the below response.

HTTP/1.1 200 
Content-Type: application/json;charset=UTF-8
Transfer-Encoding: chunked
Date: Thu, 04 Aug 2016 13:03:11 GMT

1999999999



It is displaying the response which you shared when i try to call the same service using Get method.Below is the response.

    {
       "timestamp": 1470315684018,
       "status": 405,
       "error": "Method Not Allowed",
       "exception": "org.springframework.web.HttpRequestMethodNotSupportedException",
       "message": "Request method 'GET' not supported",
       "path": "/saveApplicationAnswer"
    }

和我用的代码是

  {
@RequestMapping(value = "/saveApplicationAnswer", method =        RequestMethod.POST, consumes = MediaType.APPLICATION_JSON_VALUE, produces =  MediaType.APPLICATION_JSON_VALUE)
public int saveApplicationAnswer(@ModelAttribute("hello")   ApplicationAnswerDTO applicationAnswer) {
    System.out.println(applicationAnswer);
    return 1999999999;
    }

请尝试使用不同的工具，最好是肥皂ui。

Answer 2

 @RequestMapping(value = "/saveApplicationAnswer", method = RequestMethod.POST, consumes = MediaType.APPLICATION_JSON_VALUE, produces = MediaType.APPLICATION_JSON_VALUE)
  public int saveApplicationAnswer(@RequestBody(ServicesConstants.SURVERY_ANSWER_FL) ApplicationAnswerDTO applicationAnswer) {

            LOG.info("ApplicationDBController fn saveApplicationAnswer BookingId {} {} {}",applicationAnswer.getBookingId(),  ServicesConstants.CUSTOMER_ID_FL, applicationAnswer.getCustomerId());
            return applicationDBService.saveapplicationAnswer(applicationAnswer);
        }

我已经更改了参考这篇文章的参数注释。

从

@ModelAttribute(ServicesConstants.SURVERY_ANSWER_FL) ApplicationAnswerDTO applicationAnswer

至

@RequestBody(ApplicationAnswerDTO applicationAnswer 

它对我有用。 似乎@RequestBody是正确的。 但我不知道@RequestBody和@ModelAttribute之间的区别。 如果有人知道不同请分享到这里。 这对某些人有帮助。

当我点缀@RequestBody(ApplicationAnswerDTO applicationAnswer)它对我@RequestBody(ApplicationAnswerDTO applicationAnswer) 。

任何方式感谢每一位人士的帮助和建议。
