Java Spring REST獲取工作就好了，但發佈json時，我得到404錯誤

我遇到了Spring REST Web服務的問題。當我嘗試發佈JSON時，我總是得到404錯誤。獲取請求可以正常工作，但不會發布。搜索整個互聯網，但無法找到類似的問題。也許你們可以幫助我。這裏是我的代碼：Java Spring REST獲取工作就好了，但發佈json時，我得到404錯誤

控制器：

package com.java.rest; 
import com.java.dto.IncomingTemperature; 
import com.java.dto.SensorsTemperature; 
import com.java.service.GetSensorsTemperature; 
import com.java.service.TemperatureService; 
import org.slf4j.Logger; 
import org.slf4j.LoggerFactory; 
import org.springframework.beans.factory.annotation.Autowired; 
import org.springframework.http.HttpStatus; 
import org.springframework.http.ResponseEntity; 
import org.springframework.web.bind.annotation.*; 


@RestController 
@RequestMapping("/rest") 
public class TemperatureRestController { 

final static Logger logger = LoggerFactory.getLogger(TemperatureRestController.class); 

@Autowired 
TemperatureService temperatureService; 
@Autowired 
GetSensorsTemperature sensorService; 

@RequestMapping(value = "/temperature", method = RequestMethod.POST, produces = "application/json") 
@ResponseBody 
public ResponseEntity<?> addTemperature(@RequestBody IncomingTemperature temperature){ 
    logger.info("Temperature: {} recieved", temperature); 
    temperatureService.addTemperature(temperature); 
    return new ResponseEntity<HttpStatus>(HttpStatus.CREATED); 
} 

@RequestMapping(value = "/temperature/{sensorId}", method = RequestMethod.GET, produces = "application/json") 
public SensorsTemperature getTemperature(@PathVariable("sensorId") Long sensorId){ 
    logger.info("Getting temperatures for sensor{}", sensorId); 
    return sensorService.getSensorsTemperature(sensorId); 
}

}

型號：

package com.java.dto; 


import com.fasterxml.jackson.annotation.JsonFormat; 

import java.io.Serializable; 
import java.util.Date; 

public class IncomingTemperature implements Serializable{ 

    private long sensorId; 

    private double temperature; 

    @JsonFormat(shape= JsonFormat.Shape.STRING, pattern="yyyy-MM-dd HH:mm:ss") 
    private Date date; 

    public long getSensorId() { 
     return sensorId; 
    } 

    public void setSensorId(long sensorId) { 
     this.sensorId = sensorId; 
    } 

    public double getTemperature() { 
     return temperature; 
    } 

    public void setTemperature(double temperature) { 
     this.temperature = temperature; 
    } 

    public Date getDate() { 
     return date; 
    } 

    public void setDate(Date date) { 
     this.date = date; 
    }

的JSON我發帖：

{ 
"sensorId" : 1, 
"temperture" : 20, 
"date" : "2016-10-20 22:10:10" 
}

編輯：

錯誤，我得到：

{ 
    "timestamp": 1477601444227, 
    "status": 404, 
    "error": "Not Found", 
    "message": "No message available", 
    "path": "/rest/temperature/" 
}

預先感謝您！

編輯2：

我剛剛創建新的項目使用相同的控制器，一切工作得很好。由於我發現問題出在春季安全問題上，出於某種原因，即使我允許所有請求，Post和Put方法也不起作用。所以那是我的問題。

404是客戶端錯誤，您需要發佈您的請求 – Jaiwo99

你能分享你的郵件curl嗎？ –

您正在發佈/休息/溫度或/休息/溫度/？注意最後的「/」。 –

使用@RestController，你並不需要在方法@ResponseBody。你得到404因爲該方法不能接受任何形式的主體內容。當方法只從HTTP請求接收內容，但不發回正文內容，您只需要consumes。除了HttpStatus，ResponseEntity<xxx>定義了方法返回的主體內容。如果它沒有返回正文內容並且只有HttpStatus，則必須使用ResponseEntity<Void>。請嘗試以下

@RequestMapping(value = "/temperature", method = RequestMethod.POST, consumes = MediaType.APPLICATION_JSON_VALUE) 
public ResponseEntity<Void> addTemperature(@RequestBody IncomingTemperature temperature){ 
    logger.info("Temperature: {} recieved", temperature); 
    temperatureService.addTemperature(temperature); 
    return new ResponseEntity<Void>(HttpStatus.CREATED); 
}

現在你應該得到的HTTPStatus 201 Created上的客戶端。

嘗試添加「消耗=」應用/ JSON的」在你的@RequestMapping這樣的：

@RequestMapping(value = "/temperature", method = RequestMethod.POST, produces = "application/json", consumes="application/json")

已經嘗試過，但可惜它不會幫助。可能有一些問題，因爲我在同一個應用程序中使用spring mvc控制器和thymeleaf？ –

嘗試增加「標題= 」接受=應用/ JSON的「在你的RequestMapping」是這樣的：

@RequestMapping(value = "/temperature", method = RequestMethod.POST, headers = "Accept=application/json")
