我正在为我的springboot应用程序使用H2内存数据库。我已经启用了hibernate.ddl-auto
。当hib创建模式时,我遇到以下异常
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]
'''
下面是实体类:
@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);
}
}
以下是数据库的application.yml
内容
spring:
profiles: mock
jpa:
database-platform: org.hibernate.dialect.H2Dialect
generate-ddl: true
hibernate:

请尝试更正此错误:
到
由于
OFFSET
是保留关键字,因此您应该强制Hibernate在Map文档中将列名括在反引号中,从而在生成的SQL中引用标识符。uinbv5nw2#
我面对同样的问题,但没有一个解决方案起作用,但如果我做了下面的工作很好。
更新了“spring.jpa.database-platform=org.hibernate.dialect.H2Dialect”之前的方言
返回到“spring.jpa.properties.休眠方言= org.hibernate.dialect.H2方言”
