Package scriptella.driver.spring

Spring Framework Integration Driver for Scriptella.

See: Description

Package scriptella.driver.spring Description

Spring Framework Integration Driver for Scriptella.

This driver allows working in The Spring Framework environment and provides an ability to locate Spring-managed data sources.

This driver acts as a proxy and relies on JDBC Bridge.

Important:

The driver requires EtlExecutorBean to operate, see examples below.

General information

Driver class:scriptella.driver.spring.Driver
URL:Name of the DataSource bean specified in the bean factory/application context
Runtime dependencies:Spring Framework

Driver Specific Properties

Name Description Required

ETL Executor Configuration

EtlExecutorBean is intended to be configured from Spring XML configuration files. See EtlExecutorBean Javadoc for details on how to configure the executor in Spring.

Example

This example creates a table Spring_Table using a connection from Spring Datasource.

Spring Application Context

Spring application context declares a datasource and an executor. Additional properties and dependencies like progress indicator may also be injected.
<beans>
    <bean id="datasource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName"><value>org.hsqldb.jdbcDriver</value></property>
        <property name="url"><value>jdbc:hsqldb:mem:spring</value></property>
        <property name="username"><value>sa</value></property>
        <property name="password"><value></value></property>
    </bean>
    <bean id="progress" class="scriptella.interactive.ConsoleProgressIndicator"/>
    <bean id="executor" class="scriptella.driver.spring.EtlExecutorBean">
        <property name="configLocation"><value>etl.xml</value></property>
        <property name="progressIndicator"><ref local="progress"/></property>
        <property name="properties"><map>
            <entry key="tableName"><value>Spring_Table</value></entry>
            </map>
        </property>
    </bean>
</beans>
ETL file etl.xml
<etl>
    <connection driver="spring" url="datasource"/>
    <script>
        CREATE TABLE ${tableName} (
            ID INT
        )
    </script>
</etl>
The usage of executor is straightforward:
EtlExecutor exec = (EtlExecutor) beanFactory.getBean("executor");
exec.execute();
Additionally you can use java.util.concurrent.Callable or java.lang.Runnable invocation interface to avoid unnecessary dependency on Scriptella in application code:
Callable exec = (Callable) beanFactory.getBean("executor");
exec.call();

Batched execution of ETL files

BatchEtlExecutorBean provides an API to execute ETL files in a batch.
