org.h2.jdbc.JdbcSQLException: Table "ALL_SEQUENCES" not found

Question

Could someone please tell me the reasons for the below error.

I am using Hibernate in my project and face the below error during server startup

15:04:27.909 [localhost-startStop-1] ERROR o.h.tool.hbm2ddl.SchemaValidator - HHH000319: Could not get database metadata

Answer 1

This happens when you use either a wrong dialect in your persistence-unit inside your persistence.xml, or you validate against the wrong database. For example, when you run your application against a local H2 database, the best choice would be to remove the dialect, since Hibernate can recognize the database without this property (if the Version of Hibernate is new enough to recognize newer databases). Another solution would be to remove the validate attribute, but I would not recommend that, since you have no database checks at startup then:

<properties>
    <property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect" />
    <property name="hibernate.hbm2ddl.auto" value="validate" />
</properties>

Answer 2

I used multiple dataSources

OracleDb1Configuration

@Primary
@Bean(name = "oracleDb1EntityManager")
public LocalContainerEntityManagerFactoryBean oracleDb1EntityManagerFactory(EntityManagerFactoryBuilder builder) {
    return builder
            .dataSource(oracleDb1DataSource)
            .properties(hibernateProperties())
            .packages("com.fengxin58.user.ddd.domain.model.oracle.db1")//设置实体类所在位置
            .persistenceUnit("oracleDb1PersistenceUnit")
            .build();
}

private Map<String, Object> hibernateProperties() {

    String env = monitorService.env();
    if(log.isDebugEnabled()) {
        log.debug("current profile: {}", env);
    }
    Resource resource = null;
    if(EnvEnum.TEST.key().equals(env)) {
        resource = new ClassPathResource("hibernate-oracle-db1-test.properties");
    }else {
        resource = new ClassPathResource("hibernate-oracle-db1.properties");
    }
    try {
        Properties properties = PropertiesLoaderUtils.loadProperties(resource);
        return properties.entrySet().stream()
                .collect(Collectors.toMap(
                        e -> e.getKey().toString(),
                        e -> e.getValue())
                );
    } catch (IOException e) {
        return new HashMap<String, Object>();
    }
}

hibernate-oracle-db1-test.properties

hibernate.hbm2ddl.auto=update

application-test.yml oracle: db1: datasource: url: jdbc:h2:mem:test driver-class-name: org.h2.Driver username: root password: db2: datasource: url: jdbc:h2:mem:test driver-class-name: org.h2.Driver username: root password:
