所以，我重新安裝操作系統，現在我有這樣的例外： javax.persistence.RollbackException：錯誤，同時提交事務javax.persistence.RollbackException：錯誤，同時提交事務
我persistance.xml：
<persistence-unit name="BookUnit">
<provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
<class>Entities.BooksEntity</class>
<properties>
<property name="hibernate.connection.url" value="jdbc:postgresql://localhost:5432/postgres"/>
<property name="hibernate.connection.driver_class" value="org.postgresql.Driver"/>
<property name="hibernate.connection.username" value="admin"/>
<property name="hibernate.connection.password" value="admin"/>
<property name="hibernate.archive.autodetection" value="class"/>
<property name="hibernate.show_sql" value="true"/>
<property name="hibernate.format_sql" value="true"/>
<property name="hbm2ddl.auto" value="update"/>
</properties>
</persistence-unit>
BookEntity：
@Entity
@Table(name = "books", schema = "public", catalog = "postgres")
public class BooksEntity {
private int id;
private String title;
private String description;
@Id
@Column(name = "id")
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
@Basic
@Column(name = "title")
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
@Basic
@Column(name = "description")
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
}
測試：
public class test {
@Test
public void test_db(){
BooksEntity book = new BooksEntity();
book.setDescription("Well this fine now");
book.setTitle("BOOOK");
EntityManager em = Persistence.createEntityManagerFactory("BookUnit").createEntityManager();
em.getTransaction().begin();
em.persist(book);
em.getTransaction().commit();
em.close();
}
}
