flink 版本是 1.9.1 release
Doc
完整不太好给因为涉及到业务信息了，抱歉，但可以给一个片段，这就是一个普通Pojo，里面只有一层，所有类型都是基础类型（及衍生）+String，大约
30 多个字段，我理解这跟字段数关系不大
```
import org.apache.commons.lang3.builder.ToStringBuilder;
import
org.apache.flink.shaded.jackson2.com.fasterxml.jackson.annotation.JsonIgnoreProperties;
/**
* @author liaoxu Date: 2020/1/13 Time: 12:03 下午.
*/
@JsonIgnoreProperties(ignoreUnknown = true)
public class Doc {
private String suv;
private Float factor = 1F;
private String st;
private String agentId;
private Long timestamp;
... // omit some, omit getters and setters
```
希望有帮助，或者您可以在钉钉联系我（钉钉号 ib1x1zy）
