多个数据库的Spring启动/ Hibernate应用程序问题

时间:2017-05-13 01:57:45

标签: java spring hibernate

尝试使用多个数据库创建一个应用程序但显然我正在做一些非常错误的事情。对不起,如果我在下面写的东西是愚蠢的,但是因为我已经开始编码它不会是我的第一次。注意我正在使用多个模式。不确定这是否是使用多个数据库编写这样的应用程序的正确方法。

实体:

@Entity
@Table(name = "buyers",schema = "toner_buyer")
public class Buyers {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name = "BUYER_ID")
    private int buyerId;

    @Column(name = "FIRST_NAME")
    private String firstName;

    @Column(name = "LAST_NAME")
    private String lastName;

    @Column(name = "BUYER_ADDRESS")
    private String buyerAddress;

    @ManyToOne
    @JoinColumn(name = "MANG_ID")
    private Manager manager;

    @OneToMany(targetEntity = Toner.class, mappedBy = "buyers",
            cascade = CascadeType.ALL, fetch = FetchType.LAZY)
    private Set<Toner> toners;

    public Buyers(){}

    public Buyers(String firstName, String lastName, String buyerAddress, Set<Toner> buyerToner) {
        this.firstName = firstName;
        this.lastName = lastName;
        this.buyerAddress = buyerAddress;
        this.toners = buyerToner;
    }

    public int getBuyerId() {
        return buyerId;
    }

    public void setBuyerId(int buyerId) {
        this.buyerId = buyerId;
    }

    public String getFirstName() {
        return firstName;
    }

    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }

    public String getLastName() {
        return lastName;
    }

    public void setLastName(String lastName) {
        this.lastName = lastName;
    }

    public String getBuyerAddress() {
        return buyerAddress;
    }

    public void setBuyerAddress(String buyerAddress) {
        this.buyerAddress = buyerAddress;
    }

    public Set<Toner> getBuyerToner() {
        return toners;
    }

    public void setBuyerToner(Set<Toner> buyerToner) {
        this.toners = buyerToner;
    }
}

第二

@Entity
@Table(name = "managers", schema = "toner_manager")
public class Manager {

    @GeneratedValue(strategy = GenerationType.AUTO)
    @Id
    @Column(name = "MANG_ID")
    private int mid;

    @Column(name = "FIRST_NAME")
    private String firstName;

    @Column(name = "LAST_NAME")
    private System lastName;

    @OneToMany(targetEntity = Buyers.class, mappedBy = "managers", cascade = CascadeType.ALL, fetch = FetchType.LAZY)
    private Set<Buyers> buyers;
}

第三

@Entity
@Table(name = "toners",schema = "toner_stock")
public class Toner {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name = "TONER_ID")
    private long id;

    @Column(name = "TONER_NAME")
    private String tonerName;

    @Column(name = "TONER_PRICE")
    private int tonerPrice;

    @Column(name = "TONER_QUANTITY")
    private int tonerQuantity;

    @ManyToOne
    @JoinColumn(name = "BUYER_ID")
    private Buyers buyers;

    public Toner(){}

    public Toner(int tonerId){
        this.id = tonerId;
    }

    public Toner(String tonerName, int tonerPrice, int tonerQuantity) {
        this.tonerName = tonerName;
        this.tonerPrice = tonerPrice;
        this.tonerQuantity = tonerQuantity;
    }

    @Override
    public String toString() {
        return "Toner{" +
                "id=" + id +
                ", tonerName='" + tonerName + '\'' +
                ", tonerPrice=" + tonerPrice +
                ", tonerQuantity=" + tonerQuantity +
                '}';
    }

    public long getId() {
        return id;
    }

    public void setId(long id) {
        this.id = id;
    }

    public String getTonerName() {
        return tonerName;
    }

    public void setTonerName(String tonerName) {
        this.tonerName = tonerName;
    }

    public int getTonerPrice() {
        return tonerPrice;
    }

    public void setTonerPrice(int tonerPrice) {
        this.tonerPrice = tonerPrice;
    }

    public int getTonerQuantity() {
        return tonerQuantity;
    }

    public void setTonerQuantity(int tonerQuantity) {
        this.tonerQuantity = tonerQuantity;
    }
}

您的mappedBy值不正确。在Manager课程中,进行以下更改:

@OneToMany(targetEntity = Buyers.class, mappedBy = "manager", cascade = CascadeType.ALL, fetch = FetchType.LAZY)
private Set<Buyers> buyers;

您的代码失败的原因是因为它应指向的ManyToOne被称为manager而未被称为managers
