实体bean(二)开发实体类，注解

1.开发实体类

package com.persia.jpa;

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

@Entity
public class Person {
	
	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;
	}
	
	

}

 

2.，在persistence.xml添加hibernate属性通过部署来自动创建数据库表

<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/persistence
    http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd" version="1.0">
    
	<persistence-unit name="JPA01PU" transaction-type="JTA">
  		<jta-data-source>java:/jpa</jta-data-source>
  		<properties>
  		<property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect"/>
  		<property name="hibernate.hbm2dll.auto" value="update"/>
  		</properties>
	</persistence-unit>
  
</persistence>

 

我这边没自动生成表，不知道在哪里可以配置。
