查詢, 結(jié)果集為AssociatedInfo:

<select resultMap='AssociatedInfo'> SELECT r.requisition_number AS business_code, r.id AS header_id, r.document_type_id AS reportTypeId, r.applicant_id as employeeId FROM fec_expense.exp_report_payment_schedule b,fec_expense.exp_report_header r WHERE b.exp_report_header_id=r.id and r.`status`=1004 and b.frozen_flag ='Y' and r.applicant_id=#{applicationId} <if test='reportNumber!=null and reportNumber != ’’'> AND r.requisition_number LIKE concat( ’%’, concat(#{reportNumber,jdbcType=VARCHAR}, ’%’)) </if> <if test='documentTypeId !=null and reportNumber != ’’'> AND r.document_type_id = #{documentTypeId} </if> <if test='formTypes != null and formTypes.size > 0'> AND r.document_type_id IN <foreach collection='formTypes' item='formId' open='(' separator=',' close=')'>#{formId} </foreach> </if> AND ( b.amount - ( SELECT COALESCE(sum( c.write_off_amount ), 0) AS write_off_amount FROM csh_write_off c WHERE c.document_header_id = b.exp_report_header_id AND c.document_line_id = b.id AND ( c.STATUS = ’Y’ OR ( c.STATUS = ’P’ AND c.operation_type = ’WRITE_OFF’ ) ) ) - ( SELECT COALESCE(sum( a.amount ), 0) AS commit_amount FROM csh_data_relation_acp a WHERE a.report_head_id = b.exp_report_header_id AND a.report_line_id = b.id AND a.document_type = ’ACP_REQUISITION’ ) > 0 ) GROUP BY r.requisition_number, b.exp_report_header_id, r.document_type_id, b.applicant_id ORDER BY r.requisition_number </select>

結(jié)果集 AssociatedInfo: 使用collection 實(shí)現(xiàn)1對(duì)多的場景, CashDataPublicReportHeaderDTO實(shí)體里包含一個(gè)行的集合List<CashDataPublicReportLineDTO> lines:

包含列表的實(shí)體類 CashDataPublicReportHeaderDTO :
