Msg

PageResult

package com.geespace.microservices.data.computing.model.server.response;import java.io.Serializable;
import java.util.List;import lombok.Data;/**** @param <T>*            Construct return entity* @author liudz* @since Oracle JDK1.8**/

BusinessDomainEnum(枚举)

}

EsDocumentConstants(常量)

package com.geespace.microservices.directory.assets.constants;/*** 资产目录功能相关符号常量* @author: liudz* @date: 2020/9/15*/
public final class EsDocumentConstants {private EsDocumentConstants(){}public static final String FILE_NAME = "file_name";public static final String FILE_TYPE = "file_type";public static final String DATABASE_NAME = "database_name";public static final String TABLE_NAME = "table_name";public static final String INCLUDE_FIELDS = "include_fields";public static final String BUSINESS_DOMAIN = "business_domain";public static final String STORE_TYPE = "store_type";public static final String UPDATE_TIME = "update_time";public static final String WHETHER_ONLINE = "whether_online";public static final String FOREIGN_ID = "foreign_id";
