創建具有多對一關系的表在 Spring 引導中出現錯誤

[英]Creating table with Many-to-One relationship gives error in Spring Boot

問題描述

我正在嘗試使用 JPA 和 Hibernate 在 Spring 引導中創建多對一一對多關系。 不幸的是，我在啟動應用程序時不斷收到異常。

這是我的貸款實體的樣子：

@Entity
public class Loan {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "loan_id")
    private Long loanId;

    @ManyToOne
    @JoinColumn(name="payments_id")
    private TotalPayment totalPayment;

    private String from;

    private String to;

    private double amount;

    public Loan(String from, String to, double amount) {
        this.from = from;
        this.to = to;
        this.amount = amount;
    }

    public Loan() {
    }
}

TotalPayment 實體如下所示：

@Entity
public class TotalPayment {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "payments_id")
    private Long paymentsId;

    @OneToMany(fetch = FetchType.LAZY, mappedBy = "totalPayment")
    private List<Loan> loans;

    private LocalDate date;

    public TotalPayment(LocalDate date) {
        this.loans = new ArrayList<>();
        this.date = date;
    }

    public TotalPayment() {
    }
}

這是我執行應用程序時的控制台 output：

from和to是 MariaDB 中的特殊關鍵字，您需要更改這些列的名稱。 或者您可以嘗試：

@Column(name = "`from`")
private String from;

@Column(name = "`to`")
private String to;
