mybatis配置对象包含对象以及List的方式

mybatis配置对象包含对象及List

这里隐藏get set方法

mybatis参数为对象中包含list情况处理

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IDs

	private List<Integer> condStatuss;//状态s
	public 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 id="selectPurchaseDeliverByPrimaryKeySelective" resultMap="purchaseResultMap">
    select
	t2. name stock_name,
	t3. supplier_name, t1.*
		from
			T_SC_PURCHASE_DELIVER t1
		left join T_SC_STOCK t2 on t1.purchase_stock_id = t2.id
		left 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我们。
