Spring Boot库项目不从 /conf文件夹中选择外部文件配置

Question

正在将Spring应用程序迁移到Spring引导。有些配置需要设置为外部。这些文件放在 /confjar文件所在的文件夹中。我有不止一个项目，一个是家长项目，其他是图书馆项目。父项目和库项目无法选择 /conf文件夹配置文件。

迁移后的当前项目结构

父项目主类配置

@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()) {

        }

    }
}

库项目配置

@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";
}

        for (String name : applicationContext.getBeanDefinitionNames()) {

        }

    }
}

库项目配置

@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";
}

现在它得到了另一个错误

如何使用Spring。配置。位置，而不是硬编码导入资源和应用程序中的值。p使用以下注释创建属性。我怎样才能读《Spring》。配置。java端的位置

java -jar myproject.jar --spring.config.location=D:/Springboot/conf

我如何解决这个问题？

不要在路径的开头使用斜杠，它将指向驱动器的根（在Windows和Linux）。没有斜杠的路径（conf/application.properties）应该可以工作，因为它将是一个相对路径。
