篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了org.h2.jdbc.JdbcSQLException:找不到表“ALL_SEQUENCES”相关的知识,希望对你有一定的参考价值。
有人可以告诉我以下错误的原因。
我在我的项目中使用Hibernate并在服务器启动期间面临以下错误
15:04:27.909 [localhost-startStop-1] ERROR o.h.tool.hbm2ddl.SchemaValidator - HHH000319: Could not get database metadata
org.h2.jdbc.JdbcSQLException: Table "ALL_SEQUENCES" not found; SQL statement:

当您在persistence-unit
中的persistence.xml
中使用错误的方言时,或者您对错误的数据库进行验证时会发生这种情况。例如,当您针对本地H2数据库运行应用程序时,最好的选择是删除方言,因为Hibernate可以识别没有此属性的数据库(如果Hibernate的版本足以识别新的数据库)。另一个解决方案是删除validate属性,但我不建议这样做,因为你在启动时没有数据库检查:
<properties>
<property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect" />
<property name="hibernate.hbm2ddl.auto" value="validate" />
</properties>
我使用了多个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 =更新
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

您必须确保创建表和序列。如果它被创建,那么它将起作用。
表"ALL_SEQUENCES"
未创建。请检查您的数据库是否存在?
您的问题是没有创建序列,也没有创建表。
Solution:
检查你的hibernate.cfg.xml。配置不好。为了您的澄清,我在下面给了一个cfg file:
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<!-- Database connection settings -->
<property name="connection.driver_class">org.h2.Driver</property>
<property name="connection.url">jdbc:h2:database/test</property>
<property name="connection.username">sa</property>
<property name="connection.password"/>
<property name="hibernate.default_schema">PUBLIC</property>
<!-- JDBC connection pool (use the built-in) -->
<property name="connection.pool_size">1</property>
<!-- SQL dialect -->
<property name="dialect">org.hibernate.dialect.H2Dialect</property>
<!-- Disable the second-level cache -->
<property name="cache.provider_class">org.hibernate.cache.internal.NoCacheProvider</property>
<!-- Echo all executed SQL to stdout -->
<property name="show_sql">true</property>
<!-- Drop and re-create the database schema on startup -->
<property name="hbm2ddl.auto">create</property>
<mapping class="au.com.ozblog.hibernate.h2.example.User"/>
</session-factory>
</hibernate-configuration>
