输入的参数应该是一个model，有id属性，当插入完成后，新产生的表中的自增id会赋值为输入的参数对象中的id
<insert id="addFinanceApply" parameterType="com.....model.FinanceApply"> <selectKey resultType="int" keyProperty="id" order="AFTER"> SELECT last_insert_id() </selectKey> INSERT INTO finance_apply (money, from_account_id, to_account_id, apply_type, applier_id, apply_time, approver_id, <if test="approvedTime!= null"> approved_time, </if> status, remark, business_id, bank_order_id, qcompany_id, qaccount_id, payer, approval_remark, recharge_date, is_company, applier_name, approver_name, customer_name, customer_account, customer_account_number, customer_city, <if test="resetStatus != null"> reset_status, </if> <if test="manualClaimStatus != null"> manual_claim_status, </if> <if test="financialSystemType != null and financialSystemType != '' "> financialSystem_Type, </if> transfer_type, transaction_id )VALUES( #{money}, #{fromAccountId}, #{toAccountId}, #{applyType}, #{applierId}, now(), #{approverId}, <if test="approvedTime != null"> #{approvedTime}, </if> #{status}, #{remark}, #{businessId}, #{bankOrderId}, #{qcompanyId}, #{qaccountId}, #{payer}, #{approvalRemark}, #{rechargeDate}, #{isCompany}, #{applierName}, #{approverName}, #{customerName}, #{customerAccount}, #{customerAccountNumber}, #{customerCity}, <if test="resetStatus != null"> #{resetStatus}, </if> <if test="manualClaimStatus != null"> #{manualClaimStatus}, </if> <if test="financialSystemType != null and financialSystemType != '' "> #{financialSystemType}, </if> #{transferType}, #{transactionId} ); </insert>
