springdata jpa自動建表

application.properties文件內容為：

spring.datasource.driverClassName=com.mysql.cj.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/demo?characterEncoding=utf-8&serverTimezone=GMT%2B8
spring.datasource.username=root
spring.datasource.password=root
spring.jpa.hibernate.ddl-auto=update
spring.jpa.show-sql=true

自動建表實體對象為：

package com.ysoo.entity;

import org.hibernate.annotations.GenericGenerator;

import javax.persistence.*;
import java.io.Serializable;

@Entity
@Table(name = "t_user")
public class User implements Serializable {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO, generator = "uuid")
    @GenericGenerator(name = "uuid", strategy = "uuid2")
    @Column(name = "id")
    private String id;

    @Column(name = "name")
    private String name;

    @Column(name = "password")
    private String password;

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }
}

@GeneratedValue和@GenericGenerator注解需要如上配置 否則會出現建表不成功或者生成hibernate_sequence多余的表
