mybatis配置对象包含对象以及List的方式

这里隐藏get set方法

public class BatchManagerViewVo implements Serializable{ /*** @Description: serialVersionUID : TODO*/ private static final long serialVersionUID = 1L; private List<ResourcesItemDto> resourceItem;private List<PriceInfoDto> priceInfo;/** * 主键（PM200600001） */ @Id @Column(name = 'ID') private String id; public List<ResourcesItemDto> getResourceItem() {return resourceItem;}public void setResourceItem(List<ResourcesItemDto> resourceItem) {this.resourceItem = resourceItem;}public List<PriceInfoDto> getPriceInfo() {return priceInfo;}public void setPriceInfo(List<PriceInfoDto> priceInfo) {this.priceInfo = priceInfo;} /** * 场次名称 */ @Column(name = 'BATCH_NAME') private String batchName; /** * 会员名称 */ @Column(name = 'MEMBER_NAME') private String memberName; /** * 发起竞价的会员代码 */ @Column(name = 'MEMBER_CODE') private String memberCode; /** * 委托状态：0-已生成，1-已发布，2.竞价中 3-已撤消，4--已作废，5-已完成 */ @Column(name = 'BATCH_STATE') private String batchState; /** * 委托申请时间 */ @Column(name = 'BATCH_DATE') private Date batchDate; /** * 结束时间 */ @Column(name = 'END_TIME') private Date endTime; /** * 开始时间 */ @Column(name = 'START_TIME') private Date startTime; /** * 履约保证金是否已经支付 1 - 已经支付 0 - 未支付(只有此状态为1才允许开始拍卖) */ @Column(name = 'BOND_PAYMENT_STATUS') private String bondPaymentStatus; /** * 结算方式：1-场外结算（默认） 2- 场内结算 */ @Column(name = 'SETTLEMENT_MODE') private String settlementMode; /** * 作废时间 */ @Column(name = 'INVALID_DATE') private Date invalidDate; /** * 审核操作员 */ @Column(name = 'AUDIT_OPERATOR') private String auditOperator; /** * 终止操作员 */ @Column(name = 'STOP_OPERATOR') private String stopOperator; /** * 作废操作员 */ @Column(name = 'INVALID_OPERATOR') private String invalidOperator; /** * 申请操作员 */ @Column(name = 'APPLY_OPERATOR') private String applyOperator; /** * 公告日 */ @Column(name = 'ANNOUNCEMENT_DAY') private Date announcementDay; /** * 竞价日 */ @Column(name = 'BID_DAY') private Date bidDay; /** * 买方保证金 */ @Column(name = 'BUYER_DEPOSIT') private BigDecimal buyerDeposit; /** * 卖家保证金 */ @Column(name = 'SELLER_BOND') private BigDecimal sellerBond; /** * 强制终止理由 */ @Column(name = 'FORCED_TERMINATION_REASON') private String forcedTerminationReason; /** * 终止委托审核理由（待定） */ @Column(name = 'AUDIT_STOP_REASON') private String auditStopReason; /** * 终止委托审核时间（待定） */ @Column(name = 'AUDIT_STOP_DATE') private Date auditStopDate; /** * 终止委托申请理由（待定） */ @Column(name = 'APPLY_STOP_REASON') private String applyStopReason; /** * 终止委托申请时间（待定） */ @Column(name = 'APPLY_STOP_DATE') private Date applyStopDate; /** * 拒绝审核委托理由（待定） */ @Column(name = 'REFUSE_AUDIT_REASON') private String refuseAuditReason; /** * 委托审核时间（待定） */ @Column(name = 'AUDIT_TIME') private Date auditTime; /** * 定向竞价0否1是1 */ @Column(name = 'IS_DIRECTIONAL_BID') private String isDirectionalBid; /** * 定向的原因，当场次定向时必须输入 */ @Column(name = 'DIRECTIONAL_REASON') private String directionalReason; /** * 是否需要发送短信0不发送1发送 */ @Column(name = 'IS_SEND_MESSAGE') private String isSendMessage; /** * 是否显示中标价格 */ @Column(name = 'IS_SHOW_DEAL_PRICE') private String isShowDealPrice; /** * 是否显示定价 */ @Column(name = 'IS_SHOW_ORDER_PRICE') private String isShowOrderPrice; /** * 是否显示中标会员 */ @Column(name = 'IS_SHOW_DEAL_MEMBER') private String isShowDealMember; /** * 最少响应人数 */ @Column(name = 'MINIMUM_RESPONSE') private String minimumResponse; /** * 是否显示成交结果 */ @Column(name = 'ISSHOWDEALRESULT') private String isshowdealresult; /** * 竞价模式：1-公开增价，2自由报价,3-荷式竞价 */ @Column(name = 'BIDDING_TYPE') private String biddingType; /** * 报盘方式：1-单价，2-总价 */ @Column(name = 'OFFER_TYPE') private String offerType; /** * 是否显示起拍价 1显示（默认） 2不显示 */ @Column(name = 'IS_SHOW_STARTING_PIRCE') private String isShowStartingPirce; /** * 域名 */ @Column(name = 'DOAMIN') private String doamin; /** * 协议 */ @Column(name = 'EDITMENT') private String editment;}

mybatis是一个非常好用且灵活的持久层框架，但也正是因为太过灵活，导致有时候参数很难整理。我把我在项目中遇到的一个特殊情况列出来，希望下次再碰到时，也有个印象。

实体类如下：

package com.kxlive.erp.sc.stock.vo; import java.util.Date;import java.util.List; import org.springframework.format.annotation.DateTimeFormat; import com.kxlive.erp.sc.stock.po.PurchaseDeliver; public class QueryPurchaseDeliverVo extends PurchaseDeliver{ private Long merchantId;private Long stockId;@DateTimeFormat(pattern = 'yyyy-MM-dd')private Date startTime;//发货开始时间@DateTimeFormat(pattern = 'yyyy-MM-dd')private Date endTime;//发货结束时间 private Integer page;//当前页private Integer rows;//每页记录数private String stockName;//仓库名private String supplierName;//供应商名称private List<Long> condSupplierIds;//供应商IDsprivate List<Integer> condStatuss;//状态spublic Date getStartTime() {return startTime;}public void setStartTime(Date startTime) {this.startTime = startTime;} public Date getEndTime() {return endTime;} public void setEndTime(Date endTime) {this.endTime = endTime;} public Integer getPage() {return page;} public void setPage(Integer page) {this.page = page;} public Integer getRows() {return rows;} public void setRows(Integer rows) {this.rows = rows;} public String getStockName() {return stockName;} public void setStockName(String stockName) {this.stockName = stockName;} public String getSupplierName() {return supplierName;} public void setSupplierName(String supplierName) {this.supplierName = supplierName;} public List<Long> getCondSupplierIds() {return condSupplierIds;} public void setCondSupplierIds(List<Long> condSupplierIds) {this.condSupplierIds = condSupplierIds;} public List<Integer> getCondStatuss() {return condStatuss;} public void setCondStatuss(List<Integer> condStatuss) {this.condStatuss = condStatuss;} public Long getMerchantId() {return merchantId;} public void setMerchantId(Long merchantId) {this.merchantId = merchantId;} public Long getStockId() {return stockId;} public void setStockId(Long stockId) {this.stockId = stockId;} }

这里的实体类中，包含了一个List对象，所以在写xml文件的时候多少对我这种菜鸟有点难度。

<select resultMap='purchaseResultMap'> selectt2. name stock_name,t3. supplier_name, t1.*fromT_SC_PURCHASE_DELIVER t1left join T_SC_STOCK t2 on t1.purchase_stock_id = t2.idleft join T_SC_SUPPLIER t3 on t1.supplier_id = t3.id <where> <if test='queryCondition.ifDel != null'> and t1.if_del=#{queryCondition.ifDel,jdbcType=INTEGER} </if> <if test='queryCondition.condSupplierIds != null'> and t1.supplier_id in <foreach collection='queryCondition.condSupplierIds' item='supplierId' index='index' separator=',' open='(' close=')'> #{queryCondition.condSupplierIds[${index}],jdbcType=BIGINT} </foreach> </if> <if test='queryCondition.condStatuss != null'> and t1.status in <span style='color:#ff0000;'><foreach collection='queryCondition.condStatuss' item='status' separator=',' index='index' open='(' close=')'> #{queryCondition.condStatuss[${index}],jdbcType=INTEGER} </foreach></span> </if> <if test='queryCondition.merchantId != null'> and t1.merchant_id=#{queryCondition.merchantId,jdbcType=BIGINT} </if><if test='queryCondition.stockId != null'> and t1.purchase_stock_id=#{queryCondition.stockId,jdbcType=BIGINT} </if> <if test='queryCondition.startTime != null'> <![CDATA[ and DATE_FORMAT(t1.create_time, ’%Y-%m-%d’) >= DATE_FORMAT(#{queryCondition.startTime}, ’%Y-%m-%d’)]]> </if> <if test='queryCondition.endTime != null'> <![CDATA[ and DATE_FORMAT(t1.create_time, ’%Y-%m-%d’) <= DATE_FORMAT(#{queryCondition.endTime}, ’%Y-%m-%d’)]]> </if> <if test='queryCondition.name != null and queryCondition.name != ’’ '> and t1.name like CONCAT(’%’, #{queryCondition.name, jdbcType=VARCHAR}, ’%’) </if> <if test='queryCondition.deliverNo != null'> and t1.deliver_no like CONCAT(’%’, #{queryCondition.deliverNo, jdbcType=VARCHAR}, ’%’) </if> </where> order by t1.create_time desc </select>

标红的地方，即为应用。在foreach循环中，引用index作为list的下标，这样即可将对象中的所有数据取出。

以上为个人经验，希望能给大家一个参考，也希望大家多多支持好吧啦网。
