springmvc设置json过滤:
1、spring boot 返回的json中保留值为null的属性
@JsonSerialize(include= JsonSerialize.Inclusion.ALWAYS)
public class Config {

    private String cfCode;
    private Integer cfFlag;
    private String cfVal;
    private String cfExplain;
    private Integer orderNum;

    ......
}

2、spring boot 返回的json中去掉值为null的属性

@JsonSerialize(include= JsonSerialize.Inclusion.NON_NULL)

public class Config {

    private String cfCode;
    private Integer cfFlag;
    private String cfVal;
    private String cfExplain;
    private Integer orderNum;

    ......
}
