1. 在实体bean里加上注解之后，依旧无效

public class SynchronizedBean {
    @JsonProperty
    private String exceptionId;
    @JsonProperty
    private String[] cityIds;
    
    
    @JsonIgnore
    public String getExceptionId() {
        return exceptionId;
    }
    @JsonIgnore
    public void setExceptionId(String exceptionId) {
        this.exceptionId = exceptionId;
    }
    @JsonIgnore
    public String[] getCityIds() {
        return cityIds;
    }
    @JsonIgnore
    public void setCityIds(String[] cityIds) {
        this.cityIds = cityIds;
    }
    
}

2.在上传的JSON中实体类的名称(SynchronizedBean封装成的实体类名要与你定义的类名一致)

var json = "SynchronizedBean={"exceptionId":""+exceptionId+"","cityIds":["

3.至于实体类名中的首字母大小写与上传的JSON中对于的属性的大小写是否需要一致，暂不太清楚
