【中文标题】Spring Boot 库项目未从 /conf 文件夹中选择外部文件配置【英文标题】：Spring Boot Library project not picking External file configuration from /conf folder 【发布时间】：2020-02-23 14:36:39 【问题描述】：正在将spring应用程序迁移到spring boot。一些配置需要设置为外部。这些文件放在jar文件所在的/conf文件夹中。我有多个项目，一个是父项目，其他是库项目。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";
错误日志

现在又出现一个错误

如何使用 spring.config.location 而不是使用以下注释硬编码导入资源和 application.pproperties 中的值。如何在 java 端阅读 spring.config.location p>
java -jar myproject.jar --spring.config.location=D:/Springboot/conf
我该如何解决这个问题？
【问题讨论】：
第二次编辑请查看***.com/a/25862357/4929038 【参考方案1】：不要在路径的开头使用斜杠，它将指向驱动器的根目录（Windows 和 Linux 上都如此）。没有斜杠 (conf/application.properties) 的路径应该可以工作，因为它将是一个相对路径。
【讨论】：
我已经改变了，基于你的 cmets.now 得到另一个错误。 快速谷歌搜索链接到this SO 主题。希望对您有所帮助。 无法理解这一点。我可以加载 application.property 文件，但无法使用 @ImportantResource() 导入外部 xml 文件以上是关于Spring Boot 库项目未从 /conf 文件夹中选择外部文件配置的主要内容，如果未能解决你的问题，请参考以下文章
Spring Boot 应用程序未从 Spring Cloud Config Server 读取属性值
Spring Boot、Spring Cloud AWS 和 AWS SQS 未从队列中读取
未从 application.properties 中提取 Spring Boot JOOQ sql 方言
Spring Boot 未从 application.properties 加载用户名
前端 (HTML) 未从 Microsoft Azure 中的 mysql 数据库获取 Spring Boot 应用程序中的数据
