Spring Boot Library project not picking External file configuration from /conf folder - spring

Question

Am migrating spring application to spring boot.Some configuration need to be set as external.Those files are place in /conf folder where the jar file exist.I have more than one project,one is parent and others are library project.Parent and library project could not pick /conf folder configuration files.
current project structure after migrate
Parent project Main class Configuration
#SpringBootApplication(exclude = { DataSourceAutoConfiguration.class, HibernateJpaAutoConfiguration.class,
org.springframework.boot.autoconfigure.gson.GsonAutoConfiguration.class })
#ComponentScan(basePackages = { "com.data.*" })
#Profile(ContextProfileNames.SERVICE)
#ImportResource(locations = {
"/conf/spring/service-config.xml",
"/conf/spring/datasource-config.xml"
})
public class ServiceMain {
public static void main(String[] args) {
ConfigurableApplicationContext applicationContext = new SpringApplicationBuilder(ServiceMain.class)
.properties("spring.config.name:application.properties",
"spring.config.location=/conf/application.properties")
.build()
.run(args);
for (String name : applicationContext.getBeanDefinitionNames()) {
}
}
}
Library project configuration
#Configuration
public class ConfigurationFactory
{
public static final String extConfPath="/conf";
public static final String REQ_CONF = extConfPath+"/Configuration.xml";
public static final String FILTER_XML_CONF = extConfPath+"/DocFilter.xml";
}

.run(args);
for (String name : applicationContext.getBeanDefinitionNames()) {

}
Library project configuration
#Configuration

How can i use spring.config.location instead of hardcoding the values in import resources and application.pproperties using the below comment.How can i read spring.config.location in java side
java -jar myproject.jar --spring.config.location=D:/Springboot/conf
How can i solve this issue?

Answer 1

Do not use slash at the beginning of the path, it will point to the root of the drive (both on Windows and Linux). Having the path without the slash (conf/application.properties) should work, as it will be a relative path then.
