请帮我解决这个问题。我试图用mySql做一个序列。这是我的域类

@Entity
@Table(name="PATIENT")
public class Patient {
    @Id
    @Column(name="id", nullable=false)
    @SequenceGenerator(name="patient_seq", sequenceName="patient_id_seq")
    @GeneratedValue(strategy = GenerationType.SEQUENCE ,generator="patient_seq")
    private Integer id;

    @Column private String name;
    @Column private Integer age;
    @Column private String illness;

这里显示了我的休眠属性

jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/test
jdbc.username=root
jdbc.password=


hibernate.dialect=org.hibernate.dialect.MySQLDialect
hibernate.show_sql=true
hibernate.hbm2ddl.auto=update
hibernate.generate_statistics=true

这里显示了我的输出错误

Caused by: org.hibernate.MappingException: Dialect does not support sequences

Mysql不支持序列。

解决此问题的一种方法是，创建一个只有一个字段的表并将生成器指向该表。例如：

 <id column="id" name="id" type="java.lang.Long">
      <generator class="org.hibernate.id.enhanced.SequenceStyleGenerator"> 
            <param name="sequence_name">HIBERNATE_SEQUENCE</param>
            <param name="optimizer">none</param>
            <param name="increment_size">1</param> 
         </generator>
    </id>

在 Spring Boot 中，它会抛出一个错误，说“org.hibernate.dialect.MySQL5Dialect 不支持池化序列”。因为 Mysql 不支持序列。发生此错误是因为您在实体类中使用了以下行。

 @SequenceGenerator(name="patient_seq", sequenceName="patient_id_seq")
    @GeneratedValue(strategy = GenerationType.SEQUENCE ,generator="patient_seq")

您只需要将上面的代码行替换为，

@GeneratedValue(strategy=GenerationType.AUTO)

确保您的 application.properties 文件具有以下行。

spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
