如何使用OracleDataTypeFactory为Oracle配置Spring Data

Question

我是该社区的新手，不确定是否在正确的位置发布...还将其发布在Oracle的OTN上。

我是Oracle的老手，但是对Spring Data还是陌生的，在postGIS上做了一些工作，但是现在尝试将其应用于Oracle。

我的问题：我有一个新的maven项目，其中包含Entity和Repository类，以及一个使用DbUnit预加载测试数据的JUnit测试程序。

当前配置使用beans.xml文件进行设置：

<bean id="entityManagerFactory"
  class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">...
  <property name="jpaProperties">....

<bean id="vendorAdapter"
  class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
  <property name="databasePlatform" value="org.hibernate.dialect.Oracle10gDialect" />
  <property name="generateDdl" value="false" />
</bean>

<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"
  destroy-method="close">
  <property name="driverClass" value="oracle.jdbc.OracleDriver" />
  <property name="jdbcUrl"
   value="jdbc:oracle:thin:@localhost:2632:BLADE" />...

<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>

repos.count（）的测试正常。

调用repos.findByName（String）的测试失败（下面的堆栈）。

现在，当前设置不处理SDO_GEOMETRY或TIMESTAMP（0），但将管理TIMESTAMP（6）。

以下警告显示我正在使用“ DefaultDataTypeFactory”，并且可能应该使用OracleDataTypeFactory。

我还找到了OracleDataSource类，并进行了尝试，但仍然遇到相同的数据类型问题。

好的，主要问题是：

1. 谁能给我一个例子来配置dataSource或vendorAdapter以使用OracleDataTypeFactory并检索这些数据类型？

2. 我应在Java中为“几何”列使用哪种数据类型？

谢谢，

菲尔

Answer 1

好的，我们终于弄清楚了。 这里有两个问题。

首先，UnsupportedOperationException是由于在Entity中使用了错误的Java类。 对于Oracle SDO_GEOMETRY列，使用：

 import oracle.spatial.geometry.JGeometry;

 @Column(name = "Q_POINT")
 private JGeometry qPoint;

其次，可以通过将dbUnit配置为使用正确的类型工厂来解决来自dbUnit的警告。 此处的示例使用beans.xml创建具有正确设置的Bean，然后由dbunit使用：

    <bean id="vendorAdapter"
        class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
        <property name="database" value="ORACLE" />
        <property name="databasePlatform" value="org.hibernate.dialect.Oracle10gDialect" />
        <property name="generateDdl" value="false" />
    </bean>

  <!-- Beans to support DBunit for unit testing with Oracle. -->
  <bean id="dbUnitDatabaseConfig" class="com.github.springtestdbunit.bean.DatabaseConfigBean">
    <property name="datatypeFactory">
      <bean class="org.dbunit.ext.oracle.OracleDataTypeFactory"/>
    </property>
  </bean>
  <bean id="dbUnitDatabaseConnection" class="com.github.springtestdbunit.bean.DatabaseDataSourceConnectionFactoryBean">
    <property name="databaseConfig" ref="dbUnitDatabaseConfig"/>
    <property name="dataSource" ref="dataSource"/>
    <property name="schema" value="MAIN"/>
  </bean>

  <!-- Oracle connection pool -->
  <bean id="dataSource" class="oracle.jdbc.pool.OracleDataSource"
    destroy-method="close">
    <property name="connectionCachingEnabled" value="true" />
    <property name="URL">
       <value>jdbc:oracle:thin:@<dbhost>:<dbport>:<dbSID></value>
    </property>
    <property name="user">
      <value>myuser</value>
    </property>
    <property name="password">
      <value>mypwd</value>
    </property>
    <property name="connectionCacheProperties">
      <value>
        MinLimit:1
        MaxLimit:20
        InitialLimit:1
        ConnectionWaitTimeout:120
        InactivityTimeout:180
        ValidateConnection:true
      </value>
    </property>
  </bean>
