IntelliJ IDEA 2018.3.6 x64

新创建项目（New Project），选Spring Initializr，SDK使用1.8，使用默认的https://start.spring.io创建

项目元数据：注意Artifact，Packaging和Java Version Dependencies中选上Web -> Spring Web，注意选择Sping Boot的版本，这里使用的是2.7.3
指定项目名称和路径
完成后，生成项目。

在项目的根目录下的pom.xml中增加依赖（dependency）

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-jpa</artifactId>
        </dependency>

新建目录jars，引入GBase 8s的jdbc驱动和hibernate方言包（需要与hibernate版本对应或者兼容）这里使用到hibernate版本是5.6.10，对应的GBase 8s方言包可以在https://gbasedbt.com/dl/hibernate/3.0/ 中找到。

在项目src\main\resources下的application.properties配置文件中，增加spring和jpa的配置信息

spring.datasource.driver-class-name=com.gbasedbt.jdbc.Driver
spring.datasource.username=gbasedbt
spring.datasource.password=GBase123
spring.datasource.url=jdbc:gbasedbt-sqli://h01.gbasedbt.com:9089/testdb:GBASEDBTSERVER=gbase01;DB_LOCALE=zh_CN.utf8;CLIENT_LOCALE=zh_CN.utf8;IFX_LOCK_MODE_WAIT=60

# 让控制器输出json字符串格式
spring.jackson.serialization.indent-output=true
spring.jpa.hibernate.ddl-auto=create
spring.jpa.show-sql=true
# 设置数据库引擎
spring.jpa.database-platform=org.hibernate.dialect.GBasedbtDialect

创建pojo类（com.gbasedbt.springboothibernategbase8s.pojo.User.java）
创建dao接口（com.gbasedbt.springboothibernategbase8s.dao.UserDao.java）
创建service接口（com.gbasedbt.springboothibernategbase8s.service.UserService.java）
创建serviceimpl类（com.gbasedbt.springboothibernategbase8s.serviceimpl.UserServiceImpl.java）
创建Controller类（com.gbasedbt.springboothibernategbase8s.UserController.java）

启动环境
在浏览器中插入用户
在浏览器中查询用户（以id为条件）
在浏览器中删除用户（以id为条件）
后台日志显示相应的语句

大佬想问个问题，我也是这样引入gbase驱动的，可是项目打包后就加载不了gbase驱动，pom里加了如下类似配置也没用 src/mai/resource lib BOOT-INF/lib/ **/*.jar

@GBase用户9527：请问后来是怎么解决的？

如果将自动创建库表ddl配置设置为update，启动会报错。
spring.jpa.hibernate.ddl-auto=update

报错信息如下：
