You must set the nullValue of the PropertyPlaceholderConfigurer. For the example I'm using the string @null but you can also use the empty string as nullValue.

<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <!-- config the location(s) of the properties file(s) here -->
    <property name="nullValue" value="@null" />
</bean>
Now you can use the string @null to represent the null value

@Value("${stuff.value:@null}")
private String value;

If you look at the code for JdbcTemplate (one of the execute(...) methods) you will see

Connection con = DataSourceUtils.getConnection(getDataSource());
Which tries to retrieve a Connection from a ConnectionHolder registered with a TransactionSynchronizationManager.

If there is no such object, it just gets a connection from the DataSource and registers it (if it is in a transactional environment, ie. you have a transaction manager). Otherwise, it immediately returns the registered object.

This is the code (stripped of logs and stuff)
