मेरे पास एक जावा ईई एप्लिकेशन है जो कि कुछ इकाई वर्गों के साथ टोमकैट पर चल रहा है और eclipselink 2.1 और jpa 2.0 का उपयोग कर रहा है। संस्थाएं ईमेल नोटिफिकेशन और ईमेल नॉटिफिकेशन्यूयूयूआरओ हैं।इकाई बुनाई नहीं है। Eclipselink 2.1 + गतिशील बुनाई
@Entity
public class EmailNotification implements Serializable, IEntity<Integer> {
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy = GenerationType.AUTO, generator = "emailGen")
@SequenceGenerator(name = "emailGen", sequenceName = "SQ_EMAIL_NOTIFICATIONS", allocationSize=1)
@Basic(optional = false)
@Column(name = "EMAIL_ID")
private Integer emailId;
@Basic(optional = false)
@Column(name = "EMAIL_SUBJECT")

@Column(name = "BCC_EMAIL_ADDRESS")
private String bccEmailAddress;
@Column(name = "PROJECT_ID")
private Integer projectId;
//getters and setters
}
@Entity
public class EmailNotificationQueueRow implements Serializable, IEntity<Integer> {
private static final long serialVersionUID = 1L;
@Id
@Basic(optional = false)
@Column(name = "EMAIL_QUEUE_ID")
private Integer emailQueueId;
@Basic(optional = false)
@Column(name = "EMAIL_ID")
private int emailId;
@Basic(optional = false)
@Column(name = "REQUEST_DATE")
@Temporal(TemporalType.TIMESTAMP)
private Date requestDate;
@Basic(optional = false)
@Column(name = "MESSAGE_SENT_FLAG")
private String messageSentFlag;
@Column(name = "MESSAGE_SENT_DATE")
@Temporal(TemporalType.TIMESTAMP)
private Date messageSentDate;
@JoinColumn(name = "EMAIL_ID", referencedColumnName = "EMAIL_ID", updatable = false, insertable = false)
@OneToOne(fetch = FetchType.LAZY)
private EmailNotification emailNotification;
//getters and setters
}
जब भी मैं FetchType.LAZY को emailNotification चर के संबंध सेट (ऊपर के रूप में) वर्ग बुना नहीं है। यह बुनाई के लिए पंजीकृत है लेकिन कभी नहीं है।
लॉग नीचे है। ईमेल नोटिफिकेशन इकाई बुनाई है लेकिन ईमेल नॉटिफिकेशन्यूयूयूआरओ इकाई नहीं है। कोई विचार?

मैं eclipselink javaagent स्ट्रिंग का उपयोग कर रहा बिल्ला शुरू करने। इसके अलावा अन्य वनटोन मैपिंग भी हैं जो मेरी परियोजना में आलसी हैं जो बुनाई प्राप्त करते हैं। इसकी केवल एक ही कक्षा (ईमेल नॉटिफिकेशन क्यूयूआरओ) जो बुनाई नहीं होती है।
क्या आप कोशिश कर सकते हैं कि किसी भी झूठे बदलावों के लिए OneToOne पर JoinColumn या 'वैकल्पिक' पर 'शून्य' सेटिंग सेट करें? इसके अलावा, आप ग्रहण लिंक का कौन सा संस्करण उपयोग कर रहे हैं? –
