我是 Spring Boot的新手,我试图在Spring Boot中使用Apache Derby作为我的数据库创建一个简单的用户登录应用程序,不幸的是,在运行Spring Boot应用程序时,我遇到了错误.
org.hibernate.tool.schema.spi.CommandAcceptanceException: Error executing DDL “create table user (user_id integer not null, active integer, email varchar(255), last_name varchar(255), name varchar(255), password varchar(255), primary key (user_id))” via JDBC Statement
Caused by: java.sql.SQLSyntaxErrorException: Syntax error: Encountered “user” at line 1, column 14.
在检查我的pojo课时,我无法确定实际出了什么问题.
我尝试将“ spring.jpa.hibernate.ddl-auto = update”添加到我的application.properties文件中,但这似乎无济于事
以下是我的课程和Stacktrace,非常感谢您的帮助

最佳答案
好吧,这个问题是由于您使用的是SQL保留字(如usertable).
您可以看一下SQL reserved words for Derby,您有两种选择
>将用户表重命名为所需的user_account或表名.
@Table(name = "user_account")
public class User { ... }
>强制使用用户表名称.
@Table(name = "\"user\"")
public class User { ... }
