mybatis是一個(gè)非常好用且靈活的持久層框架，但也正是因?yàn)樘^(guò)靈活，導(dǎo)致有時(shí)候參數(shù)很難整理。我把我在項(xiàng)目中遇到的一個(gè)特殊情況列出來(lái)，希望下次再碰到時(shí)，也有個(gè)印象。

實(shí)體類如下：

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;//發(fā)貨開(kāi)始時(shí)間@DateTimeFormat(pattern = 'yyyy-MM-dd')private Date endTime;//發(fā)貨結(jié)束時(shí)間 private Integer page;//當(dāng)前頁(yè)private Integer rows;//每頁(yè)記錄數(shù)private String stockName;//倉(cāng)庫(kù)名private String supplierName;//供應(yīng)商名稱private List<Long> condSupplierIds;//供應(yīng)商IDsprivate List<Integer> condStatuss;//狀態(tài)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;} }

這里的實(shí)體類中，包含了一個(gè)List對(duì)象，所以在寫(xiě)xml文件的時(shí)候多少對(duì)我這種菜鳥(niǎo)有點(diǎn)難度。

<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>

標(biāo)紅的地方，即為應(yīng)用。在foreach循環(huán)中，引用index作為list的下標(biāo)，這樣即可將對(duì)象中的所有數(shù)據(jù)取出。

以上為個(gè)人經(jīng)驗(yàn)，希望能給大家一個(gè)參考，也希望大家多多支持好吧啦網(wǎng)。
