本文介绍了架构验证：缺少表[hibernate_sequences]的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我使用Spring 4.3.3.RELEASE，Hibernate 5.2.2.Final，数据库是MySQL。
我想尝试 strategy = GenerationType.TABLE 。正如我对 GenerationType.SEQUENCE 所了解的，我需要数据库中的序列来生成ID。



这是我的实体。

  @Entity（name = CommentTable.TABLE_NAME）
 public class Comment {
 
 private Integer id; 
私有字符串标题; 
私人字符串消息; 
私人LocalDateTime createdDateTime; 
私人问题; 
 
 
 public注释（）{
} 
 
 @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; 
} 
 //其他getter和setter。 
}

Spring注解配置

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

Spring xml配置

当我运行我的应用程序时，我得到

解决方案

且发生红色，因为您还没有在 @GeneratedValue 中提到 generator ..以下是示例

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


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

<?xml version="1.0" encoding="UTF-8"?>

        <property name="url" value="jdbc:mysql://localhost:3306/spring_test" />
        <property name="username" value="user" />
        <property name="password" value="1111" />
    </bean>

    <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
        <property name="entityManagerFactory" ref="emf" />
        <property name="dataSource" ref="dataSource" />
    </bean>

    <tx:annotation-driven />

</beans>

When I run my application, I get

Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'emf' defined in class path resource [config.xml]: Invocation of init method failed; nested exception is javax.persistence.PersistenceException: [PersistenceUnit: default] Unable to build Hibernate SessionFactory

解决方案

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;
