问题描述
package com.sb.firstjpaexample.pojo;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.SequenceGenerator;
import javax.persistence.Table;
import javax.persistence.TableGenerator;
@Entity
@Table(name = "EMPLOYEE")
public class Employee {
@Id
@TableGenerator(name = "TABLE_GEN", table = "SEQUENCE_TABLE", pkColumnName = "SEQ_NAME", valueColumnName = "SEQ_COUNT", pkColumnValue = "EMP_SEQ", initialValue = 1001, allocationSize = 5)
@GeneratedValue(strategy = GenerationType.TABLE, generator = "TABLE_GEN")
private int employeeId;
@Column
private String employeeName;
@Column
private String designation;
@Column
private double salary;
public int getEmployeeId() {
return employeeId;
}
public void setEmployeeId(int employeeId) {
this.employeeId = employeeId;
}
public String getEmployeeName() {
return employeeName;
}
public void setEmployeeName(String employeeName) {
this.employeeName = employeeName;
}
public String getDesignation() {
return designation;
}
public void setDesignation(String designation) {
this.designation = designation;
}
public double getSalary() {
return salary;
}
public void setSalary(double salary) {
this.salary = salary;
}
}
这个 POJO 在 JPA 中的初始值为 1001,但在 Hibernate 中将 1 作为初始值"还有一个疑问是如何使用注释在此处设置增量步长在 JPA 中,当我使用增量策略时,它显示没有问题,但显示增量问题
"This POJO takes initial value as 1001 in JPA but takes 1 as initial value in Hibernate" One more doubt how to set increment step here using annotations In JPA it shows no problem but problem in increment when i use increment strategies
请帮助我并提前致谢
