Java 如何使用泛型类型从rest调用解析json列表？

我正在尝试解析以下json：

{
  "00:00:08:00:27:5d:39:55": {
    "version": "OF_13",
    "port_desc": [

我使用以下代码集从Rest接收Json：

Map<String, SwitchAllJson> switchMap = response.getEntity(new GenericType<Map<String, SwitchAllJson>>(){});

Map switchMap=response.getEntity（新的GenericType（）{}）；

下面是我的Java类：

public class SwitchAllJson {
    private String version;
    private List<PortDescriptionJson> portDesc =new  ArrayList<PortDescriptionJson>();

    public String getVersion() {
        return version;
    }
    public void setVersion(String version) {
        this.version = version;
    }
    public List<PortDescriptionJson> getPortDesc() {
        return portDesc;
    }
    public void setPortDesc(List<PortDescriptionJson> portDesc) {
        this.portDesc = portDesc;
    }

}


public class PortDescriptionJson {

      private String portNumber;
      private String hardwareAddress;
      private String name;
      private List<String> config;
      private List<String> state;
      private List<String> currentFeatures;
      private List<String> advertisedFeatures;
      private List<String> supportedFeatures;
      private List<String> peerFeatures;
      private String currSpeed;
      private String maxSpeed;

    public String getHardwareAddress(){
         return this.hardwareAddress;
    }

    public String getPortNumber(){
         return this.portNumber;
    }

    public void setHardwareAddress(String hardwareAddress){
         this.hardwareAddress=hardwareAddress;
    }

    public void setPortNumber(String portNumber){
         this.portNumber=portNumber;
    }


    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public List<String> getConfig() {
        return config;
    }

    public void setConfig(List<String> config) {
        this.config = config;
    }

    public List<String> getState() {
        return state;
    }

    public void setState(List<String> state) {
        this.state = state;
    }

    public List<String> getCurrentFeatures() {
        return currentFeatures;
    }

    public void setCurrentFeatures(List<String> currentFeatures) {
        this.currentFeatures = currentFeatures;
    }

    public List<String> getAdvertisedFeatures() {
        return advertisedFeatures;
    }

    public void setAdvertisedFeatures(List<String> advertisedFeatures) {
        this.advertisedFeatures = advertisedFeatures;
    }

    public List<String> getSupportedFeatures() {
        return supportedFeatures;
    }

    public void setSupportedFeatures(List<String> supportedFeatures) {
        this.supportedFeatures = supportedFeatures;
    }

    public List<String> getPeerFeatures() {
        return peerFeatures;
    }

    public void setPeer_features(List<String> peerFeatures) {
        this.peerFeatures = peerFeatures;
    }

    public String getCurrSpeed() {
        return currSpeed;
    }

    public void setCurrSpeed(String currSpeed) {
        this.currSpeed = currSpeed;
    }

    public String getMaxSpeed() {
        return maxSpeed;
    }

    public void setMaxSpeed(String maxSpeed) {
        this.maxSpeed = maxSpeed;
    }

我能够解析

00:00:08:00:27:5d:39:55

和版本，但我在

port_desc

中得到

null

。有人能解释一下我做错了什么吗？

将属性的名称重命名为Json字段名。e、 g.portDesc->port_desc

主题外提示：如果您想增加获得正确答案的机会，请尽量将示例限制在最低限度。没有多少人愿意调试数百行代码。阅读更多关于：/。此外，在创建这样一个最小的示例时，您很有可能会找到问题的原因。这是因为您必须在json文本和java类中使用相同的名称，否则反序列化程序将无法正确映射它们。您可以使用将json转换为java类
