如何在JPA配置中设置默认架构名称?
我发现在hibernate配置文件中,我们可以设置参数hibernate.default_schema
:
<hibernate-configuration> <session-factory>
...
<property name="hibernate.default_schema">myschema</property>
...
</session-factory>
</hibernate-configuration>
现在,我正在使用JPA,我也想这样做。否则,我必须将参数添加schema
到每个@Table注释中,例如:
@Entity@Table (name = "projectcategory", schema = "SCHEMANAME")
public class Category implements Serializable { ... }
据我了解,此参数应该在配置的此部分中:
<bean id="domainEntityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"> <property name="persistenceUnitName" value="JiraManager"/>
<property name="dataSource" ref="domainDataSource"/>
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
<property name="generateDdl" value="false"/>
<property name="showSql" value="false"/>
<property name="databasePlatform" value="${hibernate.dialect}"/>
</bean>
</property>
</bean>
<bean id="domainDataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
<property name="driverClass" value="${db.driver}" />
<property name="jdbcUrl" value="${datasource.url}" />
<property name="user" value="${datasource.username}" />
<property name="password" value="${datasource.password}" />
<property name="initialPoolSize" value="5"/>
<property name="minPoolSize" value="5"/>
<property name="maxPoolSize" value="15"/>
<property name="checkoutTimeout" value="10000"/>
<property name="maxStatements" value="150"/>
<property name="testConnectionOnCheckin" value="true"/>
<property name="idleConnectionTestPeriod" value="50"/>
</bean>
…但是我在Google中找不到它的名字。有任何想法吗?
回答:
也不知道这个的JPA属性。但是你可以仅将Hibernate属性(假设你使用Hibernate作为提供程序)添加为
...<property name="hibernate.default_schema" value="myschema"/>
...
Hibernate should pick that up
