java - 如何为 Spring Data JPA 查询设置默认架构名称？

Question

我想为 postgresql 设置默认架构。当我尝试设置属性(“hibernate.default_schema”)并使用 schema 属性更新表注释时，hibernate 仍然会生成没有任何架构名称的查询，如下所示；

select log0_.id as id1_0_ from log log0_

当我将表名更改为“dbo.log”时，我可以获得结果集，没有任何错误。

 @Table(name = "dbo.log")

有没有办法为 postgresql 查询设置默认模式？

@Configuration
@EnableJpaRepositories(
    basePackages = "com.test.repository.postgresql",
    entityManagerFactoryRef = "postgresqlEntityManagerFactory",
    transactionManagerRef = "postgresqlTransactionManager"
)
public class PostgreSQLConfig {

    ....

    @Bean(name = "postgresqlEntityManagerFactory")
    public EntityManagerFactory entityManagerFactory(@Qualifier("postgresqlDatasource") DataSource postgresqlDatasource) {

        Properties jpaProperties = new Properties();
        jpaProperties.setProperty("hibernate.dialect", hibernateDialect);
        jpaProperties.setProperty("hibernate.show_sql", hibernateShowSql);
        jpaProperties.setProperty("hibernate.ddl-auto", hibernateDDLAuto);
        jpaProperties.setProperty("hibernate.naming.physical-strategy", hibernatePhysicalStrategy);
        jpaProperties.setProperty("hibernate.default_schema", "dbo");

        HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
        vendorAdapter.setDatabase(Database.POSTGRESQL);
        LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();
        factory.setJpaVendorAdapter(vendorAdapter);
        factory.setJpaProperties(jpaProperties);
        factory.setPackagesToScan("com.test.entity.postgresql");
        factory.setDataSource(postgresqlDatasource);
        factory.afterPropertiesSet();
        return factory.getObject();
    }

}

这是我的实体类；

@Entity
@Table(name = "log", schema = "dbo")
public class Log{
    ....
}

如果您正在使用application.properties

spring.datasource.url=jdbc:postgresql://myserver:5432/mydb

spring.jpa.properties.hibernate.default_schema=myschema

spring.datasource.username=myuser

spring.datasource.password=mypassword

spring.datasource.driver-class-name=org.postgresql.Driver
