org.h2.jdbc.JdbcSQLException：Column＆＃34; X＆＃34;在视图+ H2数据库1.4.190 + Hibernate 4.2.0.Final上找不到

标签： java spring hibernate jdbc h2

我直接使用目标数据库运行我的单元测试：Oracle 10g，我被要求在H2数据库下运行它们。

因此，在生成了不同的SQL脚本并配置了H2数据库（通过XML配置。使用Spring）后，我意识到我的一些测试失败了，而其中一些测试失败了......

我有以下视图（视图视图），它返回不同的列：

CREATE OR REPLACE FORCE VIEW ##.VIEW_OLB_SAT_COVERAGE
(
   SAT_CODE,
   ORBITAL_POSITION,
   COVERAGE_DOWN,
   COVERAGE_UP
)
AS
     SELECT DISTINCT sat_code,
                     orbital_position,
                     coverage_down,
                     coverage_up
       FROM ##.VIEW_OLB_TXP_COVERAGE
   ORDER BY sat_code ASC;

视图＆＃34; VIEW_OLB_TXP_COVERAGE＆＃34;如下：

CREATE OR REPLACE FORCE VIEW ##.VIEW_OLB_TXP_COVERAGE
(
   SAT_CODE,
   ORBITAL_POSITION,
   TXP_NO,
   COVERAGE_DOWN,
   COVERAGE_UP,
   POLARIZATION_DOWN,
   POLARIZATION_UP
)
AS
     SELECT DISTINCT ##.OLB_AVAILABLE_TXP.SAT_CODE,
                     ###.SAT_DEP.ORBIT_LOC / 3600 ORBITAL_POSITION,
                     ##.OLB_AVAILABLE_TXP.TXP_NO,
                     ###.TXP.CUR_DN_COVERAGE COVERAGE_DOWN,
                     ###.TXP.CUR_UP_COVERAGE COVERAGE_UP,
                     ###.TXP.TXP_DN_POL,
                     ###.TXP.TXP_UP_POL

      ... The rest is omitted for clarity

Hibernate实体如下：

@Component(value = "viewOlbSatCoverage")
@Scope("prototype")
@Entity
@Table(name = "VIEW_OLB_SAT_COVERAGE", schema = "##")
public class ViewOlbSatCoverage implements Serializable {

    private static final long serialVersionUID = -6728959649786852446L;

    @Id
    private ViewOlbSatCoverageId viewOlbSatCoverageId;

    public ViewOlbSatCoverageId getViewOlbSatCoverageId() {
        return viewOlbSatCoverageId;
    }

    public void setViewOlbSatCoverageId(ViewOlbSatCoverageId viewOlbSatCoverageId) {
        this.viewOlbSatCoverageId = viewOlbSatCoverageId;
    }

    @Override
    public String toString() {
        return "ViewOlbSatCoverage : [viewOlbSatCoverageId=" + viewOlbSatCoverageId == null ? "null"
                : viewOlbSatCoverageId.toString() + "]";
    }
}

@Component(value = "viewOlbSatCoverageId")
@Scope("prototype")
@Embeddable
public class ViewOlbSatCoverageId implements Serializable {

    private static final long serialVersionUID = 2822316442843031126L;

    @Column(name = "COVERAGE_DOWN")
    private String coverageDown;

    @Column(name = "COVERAGE_UP")
    private String coverageUp;

    @Column(name = "SAT_CODE")
    private String satCode;

    @Column(name = "ORBITAL_POSITION")
    private BigDecimal orbitalPosition;

    public ViewOlbSatCoverageId() {

    }

    public ViewOlbSatCoverageId(String satCode, BigDecimal orbitalPosition, String coverageDown, String coverageUp) {
        setSatCode(satCode);
        setOrbitalPosition(orbitalPosition);
        setCoverageDown(coverageDown);
        setCoverageUp(coverageUp);
    }

// Getters, setters omitted for clarity ...

}

正如我所提到的，目标数据库是Oracle 10g，并且一切正常（当应用程序运行时）。 但是当我运行H2数据库进行单元测试时，以下方法（findDistinctAllOrbitalPositions）不起作用：

    @Repository
    public class ViewOlbSatCoverageDaoImpl extends GenericDaoImpl<ViewOlbSatCoverage> implements ViewOlbSatCoverageDao {

        public ViewOlbSatCoverageDaoImpl() {
            setGenericClass(ViewOlbSatCoverage.class);
            setDaoLogger(ViewOlbSatCoverageDaoImpl.class);
        }

        @Override
        @SuppressWarnings("unchecked")
        public List<BigDecimal> findDistinctAllOrbitalPositions() {
            Query query = sessionFactory.getCurrentSession().createQuery(
                    "select distinct(viewOlbSatCoverageId.orbitalPosition) from " + genericClass.getSimpleName()
                    + " order by viewOlbSatCoverageId.orbitalPosition asc"); // genericClass is ViewOlbSatCoverage
            return query.list();
        }

}

如您所见，我使用的是HQL，但也使用了Criteria API。

当我从命令行启动maven时：

mvn clean -Dtest=ViewOlbSatCoverageDaoImplTestCase test

它给了我以下内容：

我已经阅读了很多内容，但我无法找到问题所在（错误的SQL脚本需要适应H2数据库，或者可能是H2数据库配置。列别名很重要？）。

注意：模式已被混淆。

提前感谢指针。

答案 0 :(得分：0)

我找到了解决问题的方法。 在我的“applicationContext-test.xml”文件中声明的SQL脚本（其中一些在SOF中发布的示例中被省略）没有很好地排序，导致视图具有INVALID状态。 - ＆GT;导致Hibernate完成生成的SQL查询，抱怨某些表和/或列未找到。

由于优秀的H2网络服务器允许我查看内存数据，我发现了问题（以及解决方案）。在SCHEMA_INFORMATION部分，我看到了VIEWS，当点击它时，我看到STATUS = INVALID。

为了使用Spring XML配置添加H2 Web服务器，您可以轻松添加：

<bean id="h2Server" class="org.h2.tools.Server" factory-method="createTcpServer" init-method="start" destroy-method="stop" depends-on="h2WebServer">
        <constructor-arg value="-tcp,-tcpAllowOthers,-tcpPort,9992"/>
    </bean>

    <bean id="h2WebServer" class="org.h2.tools.Server" factory-method="createWebServer" init-method="start" destroy-method="stop">
        <constructor-arg value="-web,-webAllowOthers,-webPort,8882"/>
    </bean>

不要忘记将值为“h2Server”的依赖属性（所以：depends-on =“h2Server”）添加到数据源bean ，否则它将无法按预期工作！< / p>
