如何修复 org.h2.jdbc.JdbcSQLSyntaxErrorException：SQL 语句中的语法错误预期 "identifier"

Question

我正在为我的 springboot 应用程序使用 H2 内存数据库。我启用 hibernate.ddl-auto 的地方。 hibernate 正在创建模式时出现异常

Caused by: org.h2.jdbc.JdbcSQLSyntaxErrorException:
Syntax error in SQL statement "CREATE TABLE PRODUCT_OFFSET_INFO (ID BIGINT NOT NULL, MODIFIED_TIMESTAMP TIMESTAMP, OFFSET[*] BIGINT, TOPIC_NAME VARCHAR(255), PRIMARY KEY (ID))"; expected "identifier"; SQL statement:
create table PRODUCT_OFFSET_INFO (ID bigint not null, MODIFIED_TIMESTAMP timestamp, OFFSET bigint, TOPIC_NAME varchar(255), primary key (ID)) [42001-200]
'''

下面是实体 class:

@Entity
@Table(name="PRODUCT_OFFSET_INFO")
public class ProductOffsetInfo implements Serializable
{
   private static final long serialVersionUID = -2147468513335906679L;
    
   @Id
   @Column(name="ID")
   private Long ProductId;
    
   @Column(name="TOPIC_NAME")
   private String topic_name;
    
   @Column(name="OFFSET")
   private Long offset;
    
   @Column(name = "MODIFIED_TIMESTAMP")
   private Date modified;
    
   public Long getProductId() {
       return ProductId;
   }
   public void setProductId(Long ProductId) {
       this.ProductId = ProductId;
   }
    
   public String getTopic_name() {
       return topic_name;
   }
   public void setTopic_name(String topic_name) {
       this.topic_name = topic_name;
   }
    
   public Long getOffset() {
       return offset;
   }
   public void setOffset(Long offset) {
       this.offset = offset;
   }
    
   public Date getModified() {
       return modified;
   }
    
   public void setModified(Date modified) {
       this.modified = modified;
   }
}

下面是数据库配置文件：

@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(
    entityManagerFactoryRef = "productEntityManagerFactory",
    transactionManagerRef = "productTransactionManager",
    basePackages = {"com.product.repository.product"}
)
@ComponentScan({"com.product.repository.product.impl"})
@EntityScan({"com.product.commons.entities.product.models","com.product.models.product"})
public class ProductDbConfig {

        @Autowired
        private JpaProperties jpaProperties;
        @Primary
        @Bean("productHikariConfig")
        @ConfigurationProperties(prefix = "spring.datasource")
        public HikariConfig hikariConfig() {
            return new HikariConfig();
        }
    
        @Primary
        @Bean(name = "productDataSource")
        @DependsOn("productHikariConfig")
        public DataSource dataSource(@Qualifier("productHikariConfig") HikariConfig hikariConfig) {
            return new HikariDataSource(hikariConfig);
        }
    
        @Primary
        @Bean(name = "productEntityManagerFactory")
        @PersistenceContext(unitName = "product")
        public LocalContainerEntityManagerFactoryBean entityManagerFactory(
                EntityManagerFactoryBuilder builder, @Qualifier("productDataSource") DataSource datasource) {
            return builder
                    .dataSource(datasource).properties(jpaProperties.getProperties())
                    .packages("com.product.commons.entities.product.models","com.product.models.product")
                    .persistenceUnit("product")
                    .build();
        }
    
        @Primary
        @Bean(name = "productTransactionManager")
        public PlatformTransactionManager transactionManager(
                @Qualifier("productEntityManagerFactory") EntityManagerFactory entityManagerFactory) {
            return new JpaTransactionManager(entityManagerFactory);
        }
    }

下面是 DB

的 application.yml 内容

    spring:
      profiles: mock
      jpa:
        database-platform: org.hibernate.dialect.H2Dialect
        generate-ddl: true
        hibernate:
          ddl-auto: create
      datasource:
        jdbcUrl: jdbc:h2:mem:PRODUCT
        driver-class-name: org.h2.Driver
        maximumPoolSize: 10
        minimumIdle: 5
        idleTimeout: 60000
        maxLifetime: 120000
        leakDetectionThreshold: 180000
        poolName: "product"

Answer 1

尝试更正此问题：

@Column(name="OFFSET")
private Long offset;

到

@Column(name="`OFFSET`")
private Long offset;

因为 OFFSET 是休眠文档的 reserved keyword you should force Hibernate to quote an identifier in the generated SQL by enclosing the column name in backticks in the mapping document. See this section。
