java - Schema-validation: missing table [hibernate_sequences]

Question

I use Spring 4.3.3.RELEASE, Hibernate 5.2.2.Final, the database is MySQL. I wanted to try strategy = GenerationType.TABLE. As I know for GenerationType.SEQUENCE I need sequences in the database to generate ids.

This is my entity.

@Entity(name = CommentTable.TABLE_NAME)
public class Comment {

    private Integer id;
    private String title;
    private String message;
    private LocalDateTime createdDateTime;
    private Issue issue;


   public Comment() {
   }

   @Id
   @GeneratedValue(strategy = GenerationType.TABLE)
   @Column(name = CommentTable.COLUMN_ID, unique = true, nullable = false)
   public Integer getId() {
       return id;
   }

   public void setId(Integer id) {
       this.id = id;
   }
//Other getters and setters.
}

Spring annotation configuration

@Configuration
@ComponentScan("com.ita.training.otm") 
@ImportResource("classpath:/config.xml") // XML with DataSource bean
@EnableTransactionManagement
public class AppConfiguration {
}

Spring xml configuration

When I run my application, I get

Answer 1

The exception is occured because you haven't mentioned generator in @GeneratedValue..Below is the example

    @GeneratedValue(strategy=GenerationType.TABLE, generator="course")
        @TableGenerator(
                name="course",
                table="GENERATOR_TABLE",
                pkColumnName = "key",
                valueColumnName = "next",
                pkColumnValue="course",
                allocationSize=30
            )
    private int id;
