Hibernate和postgresql。導出架構時出錯

當我使用Hibernate和postgresql啓動Spring Boot應用程序時，我遇到了10個錯誤。我該如何解決它們？有什麼問題？這裏是我的實體：Hibernate和postgresql。導出架構時出錯

Customer.java

@Entity 
@Access(AccessType.FIELD) // so I can avoid using setters for fields that won't change 
public class Customer { 

    @Id 
    @GeneratedValue(strategy = GenerationType.IDENTITY) 
    private Long customerId; 

    @Embedded 
    private FirstName firstName; 
    @Embedded 
    private LastName lastName; 
    @Embedded 
    private PhoneNumber phoneNumber; 

    @ManyToOne 
    @JoinColumn(name = "ADDRESS_ID") 
    private Address address; 

    @OneToOne 
    @JoinColumn(name = "USER_ID") 
    private User user; 

    // jpa requirement 
    public Customer() { 
    } 

    public Customer(FirstName firstName, LastName lastName, 
     PhoneNumber phoneNumber, Address address, User user) { 
    this.firstName = firstName; 
    this.lastName = lastName; 
    this.phoneNumber = phoneNumber; 
    this.address = address; 
    this.user = user; 
    } 

    public Long getCustomerId() { 
    return customerId; 
    } 

    public FirstName getFirstName() { 
    return firstName; 
    } 

    public LastName getLastName() { 
    return lastName; 
    } 

    public PhoneNumber getPhoneNumber() { 
    return phoneNumber; 
    } 

    // setter for phone number is needed because customer can change his phone number 
    public void setPhoneNumber(PhoneNumber phoneNumber) { 
    this.phoneNumber = phoneNumber; 
    } 

    public Address getAddress() { 
    return address; 
    } 

    // setter for address is needed because customer can change his address 
    public void setAddress(Address address) { 
    this.address = address; 
    } 

    public User getUser() { 
    return user; 
    } 

    @Override 
    public boolean equals(Object o) { 
    if (this == o) { 
     return true; 
    } 
    if (o == null || getClass() != o.getClass()) { 
     return false; 
    } 

    Customer customer = (Customer) o; 

    if (firstName != null ? !firstName.equals(customer.firstName) : customer.firstName != null) { 
     return false; 
    } 
    if (lastName != null ? !lastName.equals(customer.lastName) : customer.lastName != null) { 
     return false; 
    } 
    return user != null ? user.equals(customer.user) : customer.user == null; 
    } 

    @Override 
    public int hashCode() { 
    int result = firstName != null ? firstName.hashCode() : 0; 
    result = 31 * result + (lastName != null ? lastName.hashCode() : 0); 
    result = 31 * result + (user != null ? user.hashCode() : 0); 
    return result; 
    } 

    @Override 
    public String toString() { 
    return "Customer{" + 
     "firstName=" + firstName + 
     ", lastName=" + lastName + 
     ", phoneNumber=" + phoneNumber + 
     '}'; 
    } 
}

User.java

@Entity 
public class User { 

    @Id 
    @GeneratedValue(strategy = GenerationType.IDENTITY) 
    private Long userId; 

    @Embedded 
    private EmailAddress emailAddress; 
    @Embedded 
    private Password password; 

    @OneToOne 
    @JoinColumn(name = "CUSTOMER_ID") 
    private Customer customer; 

    @Column 
    @Enumerated(EnumType.STRING) 
    private UserRole userRole; 

    // jpa requirement 
    public User() { 
    } 

    public User(EmailAddress emailAddress, Password password) { 
    this.emailAddress = emailAddress; 
    this.password = password; 
    this.userRole = UserRole.USER; // on creation everyone is just a user 
    } 

    public Long getUserId() { 
    return userId; 
    } 

    public EmailAddress getEmailAddress() { 
    return emailAddress; 
    } 

    public void setEmailAddress(EmailAddress emailAddress) { 
    this.emailAddress = emailAddress; 
    } 

    public Password getPassword() { 
    return password; 
    } 

    public void setPassword(Password password) { 
    this.password = password; 
    } 

    public Customer getCustomer() { 
    return customer; 
    } 

    public void setCustomer(Customer customer) { 
    this.customer = customer; 
    } 

    public UserRole getUserRole() { 
    return userRole; 
    } 

    public void setUserRole(UserRole userRole) { 
    this.userRole = userRole; 
    } 
}

而且Book.java：

@Entity 
@Access(AccessType.FIELD) // so I can avoid using setters for fields that won't change 
public class Book { 

    @Id 
    @GeneratedValue(strategy = GenerationType.IDENTITY) 
    private Long bookId; 

    @Embedded 
    private Isbn isbn; 
    @Embedded 
    private Title title; 
    @Embedded 
    private Author author; 
    @Embedded 
    private Genre genre; 
    private Year publicationYear; 
    private BigDecimal price; 

    // jpa requirement 
    public Book() { 
    } 

    public Book(Isbn isbn, Title title, Author author, Genre genre, Year publicationYear, 
     BigDecimal price) { 
    this.isbn = isbn; 
    this.title = title; 
    this.author = author; 
    this.genre = genre; 
    this.publicationYear = publicationYear; 
    this.price = price; 
    } 

    public Long getBookId() { 
    return bookId; 
    } 

    public Isbn getIsbn() { 
    return isbn; 
    } 

    public Title getTitle() { 
    return title; 
    } 

    public Author getAuthor() { 
    return author; 
    } 

    public Genre getGenre() { 
    return genre; 
    } 

    public BigDecimal getPrice() { 
    return price; 
    } 

    public Year getPublicationYear() { 
    return publicationYear; 
    } 

    // setter for price is needed because price of the book can change (discounts and so on) 
    public void setPrice(BigDecimal price) { 
    this.price = price; 
    } 

}

我對PostgreSQL設置application.properties：

spring.datasource.url= jdbc:postgresql://localhost:5432/bookrest 
spring.datasource.username=postgres 
spring.datasource.password=password 

spring.jpa.hibernate.ddl-auto=create-drop

這裏是休眠部分堆棧跟蹤（ommitted所有controoller映射）：

可能重複：http://stackoverflow.com/questions/22959373/hibernate-奇怪的例外 – esin88

user是PostgreSQL中reserved keyword。我建議重新命名實體類的一些其它的名字，或者只是使用hibernate annotations@Table指定的PostgreSQL友好的表名，如下所示：

@Entity 
@Table(name = "library_user") 
public class User {...}

改變了，但我仍然收到一些錯誤 - >在編輯1中發佈它們。 – doublemc

@doublemc這可能是由你的'create-drop'策略引起的。 Hibernate試圖刪除舊錶，並且找不到這個新的'app_user'。我建議手動刪除所有表格和約束條件，然後重新運行你的應用程序。 – esin88

問題是我沒有用戶實體中的ID設置，謝謝你的幫助。 – doublemc

用戶在大多數（如果不是全部）數據庫中都是保留字。爲此目的使用其他名稱。
