Hibernate注解方法使用主键生成策略@GeneratedValue（三）

@GeneratedValue(strategy=GenerationType.IDENTITY)

一般情况下都要写在get方法上，不容易出错

package com.bjsxt.hibernate;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;

import org.hibernate.annotations.BatchSize;

@Entity

public class Category {
private int id;
private String name;
@Id
@GeneratedValue
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
