Hibernate通过JDBC语句执行DDL时出错

标签： java mysql hibernate jdbc

我真的需要帮助，我在stackoverflow上找到的所有问题都搜索过，没有任何效果。我之前从未使用过hibernate而且我不知道我做错了什么。
这是我的存储库：https://github.com/ionutincau/test_db

我收到这个错误：

11 个答案:

答案 0 :(得分：62)

在您的CFG文件中

请更改休眠方言

<!-- SQL dialect -->
    <property name="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</property>

答案 1 :(得分：33)

尝试使用名称＆＃34; User＆＃34;创建JPA实体时出现此错误。 （在Postgres中）是保留的。 所以它的解决方法是通过@Table注释更改表名：

@Entity
@Table(name="users")
public class User {..}

或手动更改表名。

答案 2 :(得分：3)

当我尝试制作一个名为“admin”的表时，我遇到了同样的错误。 然后我使用了@Table注释，给了表一个不同的名字，比如 @Table（name =“admins”）。我认为有些词是保留的（例如： - java中的关键词），你不能使用它们。

@Entity
@Table(name = "admins")
public class Admin extends TrackedEntity {

}

答案 3 :(得分：1)

我猜你使用的是旧版本的hibernate。您可以从here下载最新版本5.2。

答案 4 :(得分：1)

你需要做的第一件事是正确的@JavaLearner解释的hibernate方言版本。然后，您确保所使用的所有hibernate依赖项版本都是最新的。通常，您需要：数据库驱动程序，如mysql-connector-java，hibernate依赖项：hibernate-core和hibernate实体管理器：hibernate-entitymanager。最后，不要忘记检查您使用的数据库表是否不是order，group，limit等保留字。它可能会让您省去很多麻烦。< / p>

答案 5 :(得分：1)

方言在最近的SQL中已删除，因此请使用

  <property name="hibernate.dialect" value="org.hibernate.dialect.MySQL57Dialect"/>

答案 6 :(得分：1)

您必须小心，因为重新输入的单词不仅用于表名，还必须检查列名，我的错误是我的其中一列被命名为“用户”。如果您使用的是PostgreSQL，则正确的方言是：org.hibernate.dialect.PostgreSQLDialect

欢呼。

答案 7 :(得分：0)

spring.jpa.hibernate.ddl-auto = update

将update更改为create，然后运行

安全运行后，再次将create更改为update，这样就不会再创建所有表，您可以使用以前的数据

答案 8 :(得分：0)

与此相关的另一个偷偷摸摸的问题是用-而不是_来命名您的列。

这种情况在创建表时会触发错误。

@Column(name="verification-token")

答案 9 :(得分：0)

在 application.properties 文件中添加此配置以轻松解决此问题。

spring.jpa.properties.hibernate.globally_quoted_identifiers=true

答案 10 :(得分：0)

可能会帮助某人： 就我而言，正如@Kirill Ch 所说，但我的表名被称为“订单”。在我将其更改为“订单”并将我的休眠方言更改为 spring.jpa.com.human.HibernateConn.hibernate.dialect=org.hibernate.dialect.HSQLDialect 之后，一切都变得很有吸引力。 如果以上都不适合您，我建议您检查数据库的所有保留关键字列表。这是 MySQL 的一个： https://dev.mysql.com/doc/refman/8.0/en/keywords.html。
