冬眠 - 外鍵查詢失敗

Question

請找我的兩個表

CREATE TABLE "DBS_P2P"."KW_PAYMENT_IMAGEE_TEST"(IMAGE_KEY INTEGER PRIMARY KEY NOT NULL GENERATED ALWAYS AS IDENTITY ( START WITH +1 INCREMENT BY +1 MINVALUE +1 MAXVALUE +2147483647 NO CYCLE CACHE 20 NO ORDER),REQUEST_ID INTEGER,IMAGE_CONTENT CLOB(5120000),FOREIGN KEY(REQUEST_ID) REFERENCES KW_PAYMENT_LINK_MASTER_TEST(REQUEST_ID)) 



CREATE TABLE "DBS_P2P"."KW_PAYMENT_IMAGEE_TEST"(IMAGE_KEY INTEGER PRIMARY KEY NOT NULL GENERATED ALWAYS AS IDENTITY ( START WITH +1 INCREMENT BY +1 MINVALUE +1 MAXVALUE +2147483647 NO CYCLE CACHE 20 NO ORDER),REQUEST_ID INTEGER,IMAGE_CONTENT CLOB(5120000),FOREIGN KEY(REQUEST_ID) REFERENCES KW_PAYMENT_LINK_MASTER_TEST(REQUEST_ID)) 


<hibernate-mapping> 
<class name="xyz" table="KW_PAYMENT_LINK_MASTER_TEST" catalog="xyz"> 
    <id name="requestId" type="int"> 
     <column name="REQUEST_ID"/> 
     <generator class="identity" /> 
    </id> 

    <property name="referenceWalletId" type="string"> 
     <column name="REFERENCE_ID"/> 
    </property> 

</class> 

<hibernate-mapping> 
<class name="com.kony.p2p.bo.KwPaymentImagetest" table="KW_PAYMENT_IMAGEE_TEST" catalog="DBS_P2P"> 

    <id name="imageKey" type="int"> 
     <column name="IMAGE_KEY" /> 
     <generator class="identity" /> 
    </id> 

    <many-to-one name="KwPaymentLinkMastertest" class="com.kony.p2p.bo.KwPaymentLinkMastertest" fetch="select" lazy="false"> 
     <column name="REQUEST_ID" not-null="false" /> 
    </many-to-one> 

    <property name="imageContent" type="string"> 
     <column name="IMAGE_CONTENT" not-null="false" /> 
    </property> 

</class> 
<filter-def name="myFilter"> 

林能插入但不能夠檢索結果。

session.createCriteria(KwPaymentLinkMastertest.class).add(Restrictions.eq("requestId", Integer.parseInt(transactionReferenceNumber))).uniqueResult(); 


    KwPaymentImagetest image = (KwPaymentImagetest) session.createCriteria(KwPaymentImagetest.class).add(Restrictions.eq("kwPaymentLinkMastertest", kwPaymentLinkMastertest)).uniqueResult(); 

收到以下錯誤

org.hibernate.QueryException：無法解析屬性：kwPaymentLinkMastertest的：com.kony.p2p.bo.KwPaymentImagetest

請幫助解決

Answer 1

我認爲你在這裏輸入錯誤。

<many-to-one name="KwPaymentLinkMastertest" with K is upper case 
while Restrictions.eq("kwPaymentLinkMastertest" with k is lower case. 

Answer 2

亞， 你是對的。

問題在於小寫字母和大寫字母，這有助於解決我的問題。

謝謝。
