Play Framework + Spring：从application.conf注入URL

Question

I'm using Spring 4.1.x with Play 2.3.x and I'm trying to inject a property value from Play's application.conf file.

I can access properties thanks to this:

@PropertySource("classpath:application.conf")

@Bean
public static PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer() {
    return new PropertySourcesPlaceholderConfigurer();
}

I have a URL value in my application.conf :

photo.url="https://our-photo-storage.net"

Note the quotes . If I remove them, Play will throw com.typesafe.config.ConfigException$Parse .

I am injecting property value like this:

@Autowired
public PhotoToUrlMapper(@Value("${photo.url}") url) {
    // trim quotes :-/
}

Spring will inject the value with the quotes . I can obviously just trim them, but I'd like to be able to inject the url without the quotes.

Notes:

• I could probably create a separate .properties file, but I'd like to avoid that (more configuration)
• I could probably use horrible static Play's Play.current.configuration.getString("photo.url") , but I actually like to write unit tests ...

Is there a reasonable workaround for this?

I guess the only way to so is to use the properties file, i don't think that's too much configuration to do, since it provides you with a better readability for your code. quoted a sample of the code you need to include your properties file

<bean id="placeholderProperties"                
        class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="locations">
            <list>
                <value>classpath:/url.properties</value>
            </list>
        </property>
        <property name="ignoreUnresolvablePlaceholders" value="true" />
        <property name="order" value="1" />
    </bean>
