關於mybatis對實體類參數綁定參數的問題

dao層的代碼：

public interface SupplierMapper extends BaseMapper<SupplierDbo>{
    /*List<SupplierDbo> getAllSupplier(@Param("type") String type,  @Param("cooperStatus") Integer cooperStatus,  @Param("name") String name,  @Param("supplierNo") String supplierNo);*/  List<SupplierDbo> getAllSupplier(@Param("supplierDbo") SupplierDbo supplierDbo,@Param("goodsClassDbo") GoodsClassDbo goodsClassDbo); }

傳入的參數為兩個實體類SupplierDbo、GoodsClassDbo

mapper中的代碼：

<select id="getAllSupplier" resultType="java.util.Map">  SELECT s.name,s.supplier_no,s.address,s.contacts,s.phone_number,
    s.contact_begin_date,s.contact_period,s.period_type,s.cooper_status,
    s.licence,s.permission,s.settle_cycle ,s.bank_account,s.bank_name,
    gc.class_name
    FROM busi_supplier s LEFT JOIN busi_supplier_rel_goods sg ON s.supplier_no = sg.supplier_no
    LEFT JOIN busi_goods_class gc ON gc.id = sg.goods_class_id
    WHERE 1=1
        <if test="goodsClassDbo.className != null and goodsClassDbo.className != ''">  AND gc.class_name = #{goodsClassDbo.className}
        </if>  <if test="supplierDbo.cooperStatus != null">  AND s.cooper_status = #{supplierDbo.cooperStatus}
        </if>  <if test="supplierDbo.name != null and supplierDbo.name != ''">  AND s.name = #{name}
        </if>  <if test="supplierDbo.supplierNo != null and supplierDbo.supplierNo != ''">  AND s.supplier_no = #{supplierDbo.supplierNo}
        </if> </select>

dao層中使用@Param，然后mapper中使用@Param中的參數對相應的參數取值。
