mdb导入示例

实体

public class LsydDTO extends MdbBaseDTO {
    @NotNull(message = "pzmj(批准面积)不能为空")
    private BigDecimal landArea;
    @NotEmpty(message = "sqdw(申请单位)不能为空")
    private String landUseCompany;
}

注:mdb导入相关DTO必须继承MDBbaseDTO且配合javax.validation相关注解,不要使用lombok注解否则生成的getset会自动加入方法级的注解,会使验证信息重复。

public class MdbBaseDTO {
    @JSONField(
        name = "SHAPE_GEOMETRY"
    )
    @NotEmpty(
        message = "图形属性不能为空"
    )
    private JSONObject shapeGeometry;
    @JSONField(
        serialize = false,
        deserialize = false
    )
    private String shape;

    public MdbBaseDTO() {
    }

    public JSONObject getShapeGeometry() {
        return this.shapeGeometry;
    }

    public void setShapeGeometry(JSONObject shapeGeometry) {
        this.shapeGeometry = shapeGeometry;
    }

    public String getShape() {
        return this.shape;
    }

    public void setShape(String shape) {
        this.shape = shape;
    }
}
