javax.persistence.RollbackException：提交事務時出錯

Question

因此，我已經重新安裝了操作系統，現在出現了以下異常： javax.persistence.RollbackException ：提交事務時出錯

我的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();
}
}

我搜索了此錯誤，但是解決方案沒有幫助我。 我想由Permision引起的問題被拒絕...

Answer 1

至於你提到的問題是：你對表有沒有許可books

Caused by: org.postgresql.util.PSQLException: ERROR: permission denied for relation books

也許下次不要顯示您的密碼，即使它在localhost

<property name="hibernate.connection.password" value="admin"/>
