在我的spring boot / hibernate应用程序中，我需要连接到属于“dbo”架构的Postgres数据库“ax2012_1”。
我有以下application.properties：
# Database
db.driver: org.postgresql.Driver
db.url: jdbc:postgresql://localhost:5432/ax2012_1
db.username: my_user_name
db.password: my_password
spring.datasource.url= jdbc:postgresql://localhost:5432/ax2012_1
spring.datasource.username=my_user_name
spring.datasource.password=my_password
spring.datasource.schema=dbo
spring.jpa.hibernate.ddl-auto=validate
# Hibernate
hibernate.dialect: org.hibernate.dialect.PostgreSQLDialect
hibernate.show_sql: true
hibernate.hbm2ddl.auto: update
entitymanager.packagesToScan: com.mycompany.myproduct.data
我的DatabaseConfig.java看起来像这样：
package com.uptake.symphony.data.configs;

return dataSource;
}

@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
LocalContainerEntityManagerFactoryBean entityManagerFactory =
new LocalContainerEntityManagerFactoryBean();
entityManagerFactory.setDataSource(dataSource);
// Classpath scanning of @Component, @Service, etc annotated class
entityManagerFactory.setPackagesToScan(
env.getProperty("entitymanager.packagesToScan"));
// Vendor adapter
HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
entityManagerFactory.setJpaVendorAdapter(vendorAdapter);

additionalProperties.put(

"hibernate.hbm2ddl.auto",
env.getProperty("hibernate.hbm2ddl.auto"));
entityManagerFactory.setJpaProperties(additionalProperties);
additionalProperties.put("hibernate.default_schema", "dbo");
return entityManagerFactory;
}
/**

@Bean

JpaTransactionManager transactionManager =

transactionManager.setEntityManagerFactory(
entityManagerFactory.getObject());
return transactionManager;

return new PersistenceExceptionTranslationPostProcessor();
}
@Autowired

}
从启动日志中我可以看出，hibernate实际上是在发现我的表“可以”：

我该怎么做才能解决这个问题？
答案 0 :(得分：27)
对于Hibernate，作为JPA提供者使用
spring.jpa.properties.hibernate.default_schema=dbo
对于普通JDBC，将其添加到连接字符串中：
jdbc:postgresql://localhost:5432/mydatabase?currentSchema=myschema
另一种选择是在每个查询对象的早期运行语句set schema 'dbo'。 （呸！）
BTW你的
spring.datasource.schema=dbo
可能是错误，因为此属性指定包含您的架构的sql文件的名称（CREATE / ALTER语句）
