Question

我在我的应用程序中使用spring boot和hibernate，下面是Model类中的配置。

@Id
@SequenceGenerator(name="SCHEMA1.INQUIRY_QUEUE_SEQ", sequenceName="SCHEMA1.INQUIRY_QUEUE_SEQ",allocationSize=1)
@GeneratedValue(strategy=GenerationType.SEQUENCE, generator="SCHEMA1.INQUIRY_QUEUE_SEQ")
@Column(name="INQ_ID")
private Integer inquiryId;

以前是数据库映射的xml配置，如下所示。

    <hibernate-mapping>
     <class name="com.company.domain.model.AnalystInquiryForm" table="INQUIRY_QUEUE" schema="SCHEMA1">
        <id name="inquiryId" type="java.lang.Integer">
        <column name="INQ_ID"/>
           <generator class="sequence">
             <param name="sequence">SCHEMA1.INQUIRY_QUEUE_SEQ</param>
           </generator>
        </id>
        <property name="transactionDate" type="java.sql.Timestamp">
          <column name="INQ_ADD_DT" />
        </property>
    </class>

    </hibernate-mapping>

获得以下错误

16:08:36.873 [http-nio-8551-exec-2] DEBUG org.hibernate.SQL - select schema1.inquiry_queue_seq.nextval from dual
16:08:37.419 [http-nio-8551-exec-2] WARN  org.hibernate.engine.jdbc.spi.SqlExceptionHelper - SQL Error: 942, SQLState: 42000

我的春季启动配置如下。

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.5.1.RELEASE</version> 
    <relativePath />
</parent>
<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-jpa</artifactId>
    </dependency>

    <dependency>
        <groupId>ojdbc</groupId>
        <artifactId>ojdbc15</artifactId>
        <version>11.2.0.2.0</version>
    </dependency>
    <dependency>
        <groupId>commons-lang</groupId>
        <artifactId>commons-lang</artifactId>
        <version>2.5</version>
    </dependency>
    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-ehcache</artifactId>
    </dependency>

中间层是

@Autowired
private AnalystInquiryFormRepository analystInquiryFormRepository;
public void addToInquiryQueue(AnalystInquiryForm form) {
     analystInquiryFormRepository.save(form);
}

我的存储库是..

import org.springframework.data.repository.CrudRepository;
import com.company.user.model.AnalystInquiryForm;
public interface AnalystInquiryFormRepository extends 
CrudRepository<AnalystInquiryForm, Integer>{

}

Answer 1

您正在使用

@GeneratedValue(strategy=GenerationType.SEQUENCE, generator="SCHEMA1.INQUIRY_QUEUE_SEQ")

这意味着DB应该有一个名为SCHEMA1.INQUIRY_QUEUE_SEQ的表。

如果该表已存在，请确保您访问此表的用户具有所有适当的权限。

Answer 2

查询中不存在表格或视图或问题，请检查查询是否准确。
