java - @TableGenerator 的初始值属性在 Hibernate 中显示问题，但在 JPA 中则不然

Question

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;
}

}

“该 POJO 在 JPA 中将初始值设置为 1001，但在 Hibernate 中将初始值设置为 1” 还有一个疑问如何使用注释在这里设置增量步长 在 JPA 中，它显示没有问题，但当我使用增量策略时增量出现问题

请帮助我并提前致谢

我刚刚遇到了同样的问题。这是与 hibernate 旧版生成器和 JPA 不匹配。

您需要将其添加到您的配置中

参见 hibernate 文档:http://docs.jboss.org/hibernate/annotations/3.5/reference/en/html/ch01.html#d0e200
