Spring-Boot: How do I reference application.properties in an @ImportResource

Question

I have an applicationContext.xml file in my Spring Boot application. In this file, it has a property placeholder - ${profile.services.url} - that\'s used to configure the \"

I've got the following code:

package demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.ImportResource;

import java.util.Collection;

@ComponentScan
@EnableAutoConfiguration
public class Application {

    public static void main(String[] args) {
        ApplicationContext applicationContext = SpringApplication.run(Application.class, args);
        Collection<Foo> shouldBeConfigured = applicationContext.getBeansOfType(Foo.class).values();
        System.out.println(shouldBeConfigured.toString());
    }
}

@Configuration
@ImportResource("/another.xml")
class XmlImportingConfiguration {
}

class Foo {
    private String name;

    public void setName(String name) {
        this.name = name;
    }

    @Override
    public String toString() {
        return "Foo{" +
                "name='" + name + '\'' +
                '}';
    }

}

I have a Spring XML configuration file, another.xml:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">

    <context:property-placeholder location="another.properties" />

    <!-- this property value is defined in another.properties, which we install in this XML file
    -->
    <bean class="demo.Foo" >
        <property name="name" value="${name.property}"/>
    </bean>

    <!-- this property value is defined in application.properties, which Spring Boot automatically installs for us.
    -->
    <bean class="demo.Foo" >
        <property name="name" value="${some.property}"/>
    </bean>

</beans>

I have the following pom.xml:

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

            </snapshots>

</project>

Finally, I have two .properties files, another.properties, and application.properties:

# application.properties 
some.property=Test

and..

# another.properties 
name.property=Another

When I run this, the output is:

[Foo{name='Another'}, Foo{name='Test'}]

Which would seem to work.

I'm not quite sure I am understanding the error. Can you elaborate, or confirm this seems satisfactory behavior for you, too please?

Answer 2

I was able to workaround my issue by configuring my Soap service in JavaConfig instead of XML:

@Value("${profile.services.url}")
private String profileServiceUrl;

@Bean
public ProfileSoapService profileSoapService() {
    final JaxWsProxyFactoryBean jaxWsProxyFactoryBean = new JaxWsProxyFactoryBean();
    jaxWsProxyFactoryBean.setServiceClass(ProfileSoapService.class);
    jaxWsProxyFactoryBean.setAddress(profileServiceUrl);
    jaxWsProxyFactoryBean.getOutInterceptors().add(getSecurityInterceptor());
    return (ProfileSoapService) jaxWsProxyFactoryBean.create();
}


private WSS4JOutInterceptor getSecurityInterceptor() { ... }
