HSQL org.hsqldb.HsqlException:模式名称无效

Question

我正在使用HSQL在我的java应用程序上运行许多单元测试.我正在使用Spring + Hibernate.从MySQL切换到HSQL时遇到问题.测试在MySQL上完美运行,但每当我改为HSQL时,我都会遇到以下异常:

Caused by: org.hsqldb.HsqlException: invalid schema name: LMS
at org.hsqldb.error.Error.error(Unknown Source)
at org.hsqldb.error.Error.error(Unknown Source)
at org.hsqldb.SchemaManager.getSchemaHsqlName(Unknown Source)

at org.hsqldb.Session.compileStatement(Unknown Source)

我的Spring配置如下:

<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
    <property name="driverClassName" value="org.hsqldb.jdbc.JDBCDriver" />
    <property name="url" value="jdbc:hsqldb:file:lms" />
    <property name="username" value="SA"/>
    <property name="password" value=""/>
</bean>


<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />

    <property name="packagesToScan">
        <list>
            <value>com.dreamteam.lms.**.*</value>
        </list>
    </property>

    <property name="hibernateProperties">
        <props>
            <!--<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>-->
            <prop key="hibernate.dialect">org.hibernate.dialect.HSQLDialect</prop>
            <prop key="hibernate.generate_statistics">true</prop>
            <prop key="hibernate.show_sql">false</prop>
            <prop key="hibernate.cache.use_second_level_cache">true</prop>
            <prop key="hibernate.cache.use_query_cache">true</prop>
            <prop key="hibernate.cache.provider_class">net.sf.ehcache.hibernate.SingletonEhCacheProvider</prop>
        </props>
    </property>
</bean>

我的一个类上的示例注释:

@Entity
@Table(name = "answer", catalog = "lms")
public class Answer implements Cloneable, Serializable, IPojoGenEntity, IAnswer {
.
.

任何见解将不胜感激.

Answer 1

制作"create-schema.sql"文件

CREATE SCHEMA lms;

添加"dataSourceInitializer"bean

<bean id="dataSourceInitializer" class="org.springframework.jdbc.datasource.init.DataSourceInitializer">
    <property name="dataSource" ref="dataSource" />
    <property name="databasePopulator">
        <bean class="org.springframework.jdbc.datasource.init.ResourceDatabasePopulator">
            <property name="continueOnError" value="true" />
            <property name="scripts">
                <list>
                    <value>classpath:SQL/create-schema.sql</value>
                </list>
            </property>
        </bean>
    </property>
</bean> 

将"depends-on"属性设置为"sessionFactory"bean

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean" depends-on="dataSourceInitializer">
...

Answer 2

我在测试期间使用以下bean来创建模式.

public class HSQLSchemaCreator {

    private String schemaName;

    private DataSource dataSource;

    public HSQLSchemaCreator(String schemaName, DataSource dataSource) {
        this.schemaName = schemaName;
        this.dataSource = dataSource;
    }


    @PostConstruct
    public void postConstruct() throws Exception {
        JdbcTemplate jdbcTemplate = new JdbcTemplate(dataSource);
        jdbcTemplate.execute("CREATE SCHEMA " + schemaName + " AUTHORIZATION DBA");
    }

}

弹簧配置:

  <bean id="hsqlSchemaCreator" class="....HSQLSchemaCreator">
       <constructor-arg name="schemaName" value="..."/>
       <constructor-arg name="dataSource" ref="dataSource"/>
  </bean>

<!-- Override entityManagerFactory to depend on hsqlSchemaCreator for tests  -->
<bean id="entityManagerFactory"  class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean" depends-on="hsqlSchemaCreator">

等等...
