Json文件返回多個值，我希望我的getter和setter在將其設置為第一個值后拒絕其他值

Question

我的json API返回了多個網絡值，我的網站僅顯示了第一個值，當我的pojo為即將到來的值重置並為接收到的最后一個值設置自身時，我正在嘗試以這樣的方式更改我的pojo文件：設置拒絕或不接受另一對。 我是json和jackson的新手，所以如果我想問更多有關您答案的問題，請放輕松，我正嘗試將json中的數據與實時網站中的數據進行比較。

我嘗試過this.name = name == null ? this.name : throw_(); this.name = name == null ? this.name : throw_(); 但這並不能解決問題。

pojo的示例-

@JsonIgnoreProperties(ignoreUnknown = true)
public class Networks{
    private String banner;
    private String description;
    private boolean is_locked;
    private String logo;
    private String name;
    private String network_analytics;
    private Number network_id;
    private String slug;
    private String thumbnail_url;
    private String url;

    public String getBanner(){
        return this.banner;
    }
    public void setBanner(String banner){
        this.banner = banner;
    }
    public String getDescription(){
        return this.description;
    }
    public void setDescription(String description){
        this.description = description;
    }
    public boolean getIs_locked(){
        return this.is_locked;
    }
    public void setIs_locked(boolean is_locked){
        this.is_locked = is_locked;
    }
    public String getLogo(){
        return this.logo;
    }
    public void setLogo(String logo){
        this.logo = logo;
    }
    public String getName(){
        return this.name;
    }
    public void setName(String name){
        this.name = name == null ? this.name : throw_();
    }
    public String getNetwork_analytics(){
        return this.network_analytics;
    }
    public void setNetwork_analytics(String network_analytics){
        this.network_analytics = network_analytics;
    }
    public Number getNetwork_id(){
        return this.network_id;
    }
    public void setNetwork_id(Number network_id){
        this.network_id = network_id;
    }
    public String getSlug(){
        return this.slug;
    }
    public void setSlug(String slug){
        this.slug = slug;
    }
    public String getThumbnail_url(){
        return this.thumbnail_url;
    }
    public void setThumbnail_url(String thumbnail_url){
        this.thumbnail_url = thumbnail_url;
    }
    public String getUrl(){
        return this.url;
    }
    public void setUrl(String url){
        this.url = url;
    }
     public String throw_() {
         throw new RuntimeException("Network name is already set, second network not allowed");
     }
}

我已將網絡列表的JsonGen代碼更改為-

public void setNetworks(List networks) {
    Networks.add(networks);
    this.networks = networks.subList(0, 1);
}

它會添加所有列表，子列表會為您提供第一個值。
