[英]JPA / Hibernate / Derby TableGenerator use negative values
[英]initialValue attribute of @TableGenerator shows issue in Hibernate but not in JPA
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;
}
}
“此POJO在JPA中将初始值为1001,在Hibernate中为1作为初始值”还有一个疑问,如何在此处使用注释设置增量步长在JPA中,当我使用增量策略时,它没有问题,但是增量问题
请帮助我,在此先感谢
我只是有同样的问题。 它与休眠的旧生成器和JPA不匹配。
您需要将此添加到您的配置中
请参阅休眠文档: http : //docs.jboss.org/hibernate/annotations/3.5/reference/en/html/ch01.html#d0e200
