@JsonSerialize的使用

前后端对状态类字段不统一，需转换

@JsonSerialize注解,主要用于数据转换,该注解作用在该属性的getter()方法上。

public class MySerializerUtils extends JsonSerializer<Integer> {
    @Override
    public void serialize(Integer status, JsonGenerator jsonGenerator, SerializerProvider serializerProvider) throws IOException, JsonProcessingException {
        String statusStr = "";
        switch (status) {
            case 0:
                statusStr = "暂存";
                break;
            case 1:
                statusStr = "待上报";
                break;
            case 2:
                statusStr = "待审核";
                break;
            case 3:
                statusStr = "已审";
                break;
            case 4:
                statusStr = "退回";
                break;
            case -1:
                statusStr = "已删";
                break;
            default:
                statusStr = "状态信息不符合";
        }
        jsonGenerator.writeString(statusStr);
    }
}

/**
 * 文字型状态值
 */
@JsonSerialize(using = MySerializerUtils.class)
private int status;
