如何使用OracleDataTypeFactory为Oracle配置Spring Data

Question

I'm new to this community, not sure if I'm posting in the right place... also posted this on Oracle's OTN.

I'm an Oracle old-hand, but new to Spring Data, having done a bit on postGIS, but now trying to apply it to Oracle.

My problem: I have a new maven project, with Entity and Repository classes, and a JUnit test program that uses DbUnit to preload test data.

The current config uses a beans.xml file to set up:

<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>

Test of repos.count() works ok.

Test to call repos.findByName(String) fails, (stack below).

Now, the current setup doesn't handle SDO_GEOMETRY, or TIMESTAMP(0), but will manage TIMESTAMP(6).

The warnings below show that I'm using "DefaultDataTypeFactory" and should probably be using OracleDataTypeFactory.

I've also found the OracleDataSource class, and tried that, but still get the same data type issues.

Ok, the big questions:

1. Can anyone point me at an example to configure the dataSource, or vendorAdapter, to use the OracleDataTypeFactory, and retrieve these data types?

2. What data type should I be using in Java for the geometry column?

Thanks,

Phil

Answer 1

Ok, we've finally figured it out. There are two problems here.

Firstly, the UnsupportedOperationException was due to using the wrong Java class in the Entity. For an Oracle SDO_GEOMETRY column, use:

 import oracle.spatial.geometry.JGeometry;

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

Secondly, the warnings from dbUnit can be resolved by configuring dbUnit to use the correct type factory. Example here uses beans.xml to create beans with the correct settings, which are then used by dbunit:

    <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>
