java - 如何使用泛型类型解析来自其余调用的 json 列表？

Question

我正在尝试解析下面的 json:

{

    ]
  }
}

我正在使用下面的代码集从 Rest 接收 Json:

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

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/。有人可以解释我做错了什么吗？

将属性名称重命名为 Json 字段名称。例如端口描述 -> 端口描述
