java jackson 忽略不存在的属性字段 和 按照属性名转json

@JsonAutoDetect(fieldVisibility = Visibility.ANY, getterVisibility = Visibility.NONE, isGetterVisibility = Visibility.NONE)
该注解的作用是：使用属性名称来转json。   防止不规范的属性报错，比如 app_id

@JsonIgnoreProperties(ignoreUnknown = true)
该注解的作用是：在进行json转对象是，防止传入的json串包含不存在的属性导致报错。

案例：
 
 
 1 @JsonAutoDetect(fieldVisibility = Visibility.ANY, getterVisibility = Visibility.NONE, isGetterVisibility = Visibility.NONE)
@JsonIgnoreProperties(ignoreUnknown = true)
public class UnifiedPayOrderResponse {
    
    private String code;
    
    private String message;
    
    private String main_order_code;
    
    private String app_id;

    public String getCode() {
        return code;
    }

    public void setCode(String code) {
        this.code = code;
    }

    public String getMessage() {
        return message;
    }

    public void setMessage(String message) {
        this.message = message;
    }

    public String getMain_order_code() {
        return main_order_code;
    }

    public void setMain_order_code(String main_order_code) {
        this.main_order_code = main_order_code;
    }

    public String getApp_id() {
        return app_id;
    }

    public void setApp_id(String app_id) {
        this.app_id = app_id;
    }

}
