春季4，REST服務從Tomcat返回415錯誤

Question

我正在嘗試使用Spring 4在REST服務中測試POST方法。在與MockMvcBuilders.standaloneSetup集成測試中，它可以正常工作，但是我將其部署在Tomcat 8.5.8中，我不明白為什么它不起作用。 我收到此消息：

                              HTTP Status 415 -

   type Status report

   message

   description The server refused this request because the request entity
   is in a format not supported by the requested resource for the
   requested method.
     ________________

但是Tomcat服務器收到此請求（從wirehark中提取）：

POST /app-1.0-SNAPSHOT/v1.0/concentrators/ HTTP/1.1 
User-Agent: curl/7.35.0 
Host: x.x.x.x:8080 
Accept: */* 
Content-Type: application/json 
Content-Length: 528 {"street":"street","num":"num","code":"code","town":"town"
,"descriptionRoom":"descriptionRoom","btPwd":"btPwd"
,"gprsPwd":"gprsPwd","gprsLogin":"gprsLogin","gprsApn":"gprsApn"
,"gprsPin":"gprsPin","motherboardId":"motherboardId","logLevel":0
,"frameSendPeriod":0,"frameCapturePeriod":0,"mQTTServerPwd":"mQTTServerPwd"
,"mQTTServerUser":"mQTTServerUser","mQTTServerIp":"mQTTServerIp"
,"ftpServerPwd":"ftpServerPwd","ftpServerUser":"ftpServerUser"
, "ftpServerIp":"ftpServerIp","numSerie" :"numSerie","idConcentrator":-1,"infoCameras":[]}

似乎很好，我不知道哪里出了問題。

我的REST服務是：

@RequestMapping(value = "/", method = RequestMethod.POST, consumes = { "application/json" }, produces = { "application/json" })
public ResponseEntity<String> post(@RequestBody ConfigurationConcentrator configurationConcentrator) {
    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.APPLICATION_JSON);
    try {
        configureConcentrator.create(configurationConcentrator);
    } catch (IncorrectDBOperation | ErrorSendMessageException e) {
        return new ResponseEntity<String>(e.getMessage(), headers, HttpStatus.BAD_REQUEST);
    }
    return new ResponseEntity<String>(HttpStatus.CREATED);
}

另外，它檢查了傑克遜的依賴關系（數據綁定，核心和注釋），並將它們添加到.war文件中。 這是我的curl命令：

 curl -X POST -H "Content-Type: application/json" --data  @addConcentrator2.json http://x.x.x.x:8080/app-1.0-SNAPSHOT/v1.0/concentrators/

看來，它無法正確解決哪個攔截器需要，但我看不到問題所在：

    @RequestMapping(value = "/{id}", method = RequestMethod.GET, consumes = { "application/json" }, produces = { "application/json" })
    public @ResponseBody ResponseEntity<ConfigurationConcentrator> get(@PathVariable("id") String id) {
....
    }

    @RequestMapping(value = "/", method = RequestMethod.POST, consumes = { "application/json" }, produces = { "application/json" })
    public ResponseEntity<String> post(@RequestBody ConfigurationConcentrator configurationConcentrator) {
....

    }

    @RequestMapping(value = "/{id}", method = RequestMethod.PUT, consumes = { "application/json" }, produces = { "application/json" })
    public ResponseEntity<String> put(@PathVariable("id") String id, @RequestBody ConfigurationConcentrator configurationConcentrator) {
....

    }

    @RequestMapping(value = "/{id}/cameras/{idcamera}", method = RequestMethod.PUT, consumes = { "application/json" }, produces = { "application/json" })
    public ResponseEntity<String> putCameras(@PathVariable("id") String id, @PathVariable("idcamera") String idCamera,
....

    }

    @RequestMapping(value = "/{id}/cameras", method = RequestMethod.POST, consumes = { "application/json" }, produces = { "application/json" })
    public ResponseEntity<String> postCameras(@PathVariable("id") String id, @RequestBody List<ConfigurationCamera> configurationCameras) {
....
    }

    @RequestMapping(value = "/{id}/initialconfiguration", method = RequestMethod.GET, consumes = { "application/json" }, produces = { "application/json" })
    public ResponseEntity<StatusInitialConfiguration> getInitialConfiguration(@PathVariable("id") String numSerie) {
....


    }

UPDATE1：我使用Accept標頭更新了curl命令。

curl -X POST -H "Content-Type: application/json" -H "Accept: application/json" --data  @addConcentrator2.json http://x.x.x.x:8080/app-1.0-SNAPSHOT/v1.0/concentrators/

UPDATE2：我認為，它正在檢測兩個攔截器：

UPDATE3：

映射JSON的類：

配置相機

package gasnatural.models;

public class ConfigurationCamera {
    private String numSerie = null;
    private String numCamera = null;
    private String cups = null;

    private String status = null;

    public ConfigurationCamera() {

    }

    public ConfigurationCamera(String numSerie, String numCamera, String cups, String status) {
        this.numSerie = numSerie;
        this.numCamera = numCamera;
        this.cups = cups;
        this.status = status;
    }

    public String getStatus() {
        return status;
    }

    public String getNumSerie() {
        return numSerie;
    }

    public String getNumCamera() {
        return numCamera;
    }

    public String getCups() {
        return cups;
    }

    public void setNumSerie(String numSerie) {
        this.numSerie = numSerie;
    }

    public void setNumCamera(String numCamera) {
        this.numCamera = numCamera;
    }

    public void setCups(String cups) {
        this.cups = cups;
    }

    public void setStatus(String status) {
        this.status = status;
    }

}

更新4

我簡化了映射的對象類，並且收到相同的錯誤。

public class DTOConfigurationConcentrator {
    private String street;
    private String num;

    public DTOConfigurationConcentrator() {
        super();
    }

    public String getStreet() {
        return street;
    }

    public void setStreet(String street) {
        this.street = street;
    }

    public String getNum() {
        return num;
    }

    public void setNum(String num) {
        this.num = num;
    }

}

似乎與json序列化工具有關，但我不知道該如何檢查。

我忘了用@EnableWebMvc標記我的配置類...
