带有多个数据库的Spring Boot / Hibernate应用程序问题
[英]Spring boot/ Hibernate application problems with multiple databases
问题描述
Attempting to make a application with multiple databases but apparently I'm doing something terribly wrong. 
尝试使一个应用程序具有多个数据库，但显然我在做某件事。 Sorry if something I wrote below is stupid, but since I've started coding it won't be my first time. 抱歉，如果我在下面写的东西很蠢，但是自从我开始编码以来，这将不是我第一次。 Note I'm using multiple schemas. 注意我正在使用多个架构。 Not sure if this is the correct way to write an app like this with multiple databases. 不知道这是否是编写具有多个数据库的应用程序的正确方法。
Entities: 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) {

}
public String getBuyerAddress() {
return buyerAddress;
}
public void setBuyerAddress(String buyerAddress) {

}
public Set<Toner> getBuyerToner() {

}
public void setBuyerToner(Set<Toner> buyerToner) {

}
}

Your mappedBy value is incorrect. 您的mappedBy值不正确。 In your Manager class, make the following change: 在您的Manager类中，进行以下更改：
@OneToMany(targetEntity = Buyers.class, mappedBy = "manager", cascade = CascadeType.ALL, fetch = FetchType.LAZY)
private Set<Buyers> buyers;
The reason your code failed was because the ManyToOne it should point to is called manager and not called managers . 您的代码失败的原因是因为它应指向的ManyToOne称为manager而不是称为managers 。
