问题 I'm trying to test some POJOs with hibernate annotations and I'm getting the same error on and on. I used the same configuration in another project and it all worked fine. I tested the jdbc connection that is used when the hib objects are tested - and the connction works fine. I have found a few other questions asked about the same error but nothing was helpful. The code in testing class with main method: public static void main(String[] args) { SessionFactory factory = new Configuration()

问题 I have the following design: One sports game has two scores (one per team) and each score has multiple player stats, one per jersey number. Both relationships are mapped as Map . This is just multi-level aggregation. Game entity: @Entity @Table(name = "\"Games\"") @NamedQuery(name = Game.FIND_ALL, query = "SELECT ga FROM Game ga") @NamedEntityGraph(name = Game.FETCH_SCORES, attributeNodes = {@NamedAttributeNode("scores")}) @NamedEntityGraph(name = Game.FETCH_SCORES_AND_PLAYER_STATS,

问题 I have the following design: For reference, I'm only posting the SimpleGame entity: @Entity @Table(name = "\"SimpleGames\"") @NamedQuery(name = SimpleGame.FIND_ALL, query = "SELECT ga FROM SimpleGame ga") @NamedQuery(name = SimpleGame.FIND_ALL_JOIN_SCORES_GROUP_BY_GAME_ID, query = "SELECT ga FROM SimpleGame ga JOIN ga.simpleScores sc GROUP BY ga.id") @NamedEntityGraph(name = SimpleGame.FETCH_SCORES, attributeNodes = {@NamedAttributeNode("simpleScores")}) public class SimpleGame implements

问题 I have a JPA-Project, which I'm trying to update to JPA 2.2.0 and EclipseLink 5.7.1 since I ran into bug 429992 of EclipseLink. With the new versions in place, I'm not able to execute my application anymore – EclipseLink throws an exception similar to the following (Short variant from my example below): [EL Warning]: metamodel: 2018-06-20 22:38:14.1--Thread(Thread[main,5,main])--The collection of metamodel types is empty. Model classes may not have been found during entity search for Java SE

问题 I am working Spring Data - Multi-column searches and Spring Data Jpa - The type Specifications<T> is deprecated where I wants to search for multiple columns like Date (Java 8 LocalDateTime , Instant , LocalDate etc.,), Integer and String data types. But as per my code, only String fields are getting considered (as per logs in where clause):: select employee0_.employee_id as employee1_0_, employee0_.birth_date as birth_da2_0_, employee0_.email_id as email_id3_0_, employee0_.first_name as first

问题 I have JPA a entity class that contains a blob field like this: @Entity public class Report { private Long id; private byte[] content; @Id @Column(name = "report_id") @SequenceGenerator(name = "REPORT_ID_GENERATOR", sequenceName = "report_sequence_id", allocationSize = 1) @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "REPORT_ID_GENERATOR") public Long getId() { return id; } public void setId(Long id) { this.id = id; } @Lob @Column(name = "content") public byte[] getContent()

问题 I've created a custom type for Hibernate to store an OffsetDateTime 's timestamp and offset (because the default JPA 2.2 / Hibernate 5.2 with java 8 support implementation loses the offset information): public class OffsetDateTimeHibernateType implements CompositeUserType { @Override public Class returnedClass() { return OffsetDateTime.class; } @Override public String[] getPropertyNames() { return new String[] {"dateTime", "zoneOffset"}; } @Override public Type[] getPropertyTypes() { // Not
