You can use spring bean profiles or conditional beans.You can use following configuration to define propertyplaceholder beans for each environment.

        <beans profile="environment1">
<bean 
    class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">

    <property name="location">
        <value>database_env1.properties</value>
    </property>
</bean>
</beans>

<beans profile="environment2">
<bean 
    class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">

    <property name="location">
        <value>database_env2.properties</value>
    </property>
</bean>
</beans>

For database configuration, a possible approach is to define the JDBC DataSource as a JNDI resource directly in your application server that you then use (see how) - this way your WAR file doesn't contain the connection information, the runtime environment does hold this info instead.

One advantage of this approach is that the connection information then can be managed by a server administrator instead of the application developer.

Not sure it meets your "no configuration outside project" requirement though.
