帶有多個數據庫的Spring Boot / Hibernate應用程序問題
[英]Spring boot/ Hibernate application problems with multiple databases
問題描述
嘗試使一個應用程序具有多個數據庫，但顯然我在做某件事。 抱歉，如果我在下面寫的東西很蠢，但是自從我開始編碼以來，這將不是我第一次。 注意我正在使用多個架構。 不知道這是否是編寫具有多個數據庫的應用程序的正確方法。
實體：
@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值不正確。 在您的Manager類中，進行以下更改：
@OneToMany(targetEntity = Buyers.class, mappedBy = "manager", cascade = CascadeType.ALL, fetch = FetchType.LAZY)
private Set<Buyers> buyers;
您的代碼失敗的原因是因為它應指向的ManyToOne稱為manager而不是稱為managers 。
