propertySources 显示为空（Spring Cloud Config）答案

【问题标题】：propertySources Shows Empty (Spring Cloud Config)propertySources 显示为空（Spring Cloud Config）
【发布时间】：2021-09-19 20:17:08
【问题描述】：

我正在尝试学习 Spring Cloud。所以我使用 Spring Starter（一个非常基础的）创建了一个新项目

我像这样配置了我的application.properties：

server.port=9090
spring.cloud.config.server.native.searchLocations=file://H:/opt/app/app.static.properties
spring.profiles.active=native

但是当我启动我的 Spring Boot 应用程序时，它可以正常启动（据我所知），但是当我点击 URL http://localhost:9090/config/default/master

我在浏览器上得到输出：

{"name":"config","profiles":["default"],"label":"master","version":null,"state":null,"propertySources":[]}

我的控制台输出是：

propertySources 不应该充满属性文件条目吗？我是新来的。所以主要是从教程和指南中学习。我的理解正确吗？

任何帮助将不胜感激。谢谢。

【问题讨论】：

尝试在记录器中启用DEBUG选项并检查日志。
你在windows机器上吗？如果是，那么您在配置文件的绝对路径中缺少一个额外的“/”
@Nemanja 我在 Windows 机器上。后来我意识到了这一点，并添加了它。但结果是一样的。我成功了spring.cloud.config.server.native.search-locations=file:///H:/opt/app/app.static.properties
@GnanaJeyam 我添加了属性logging.level.web=DEBUG，但我没有看到任何有价值的东西。但这可能是因为我不知道我在寻找什么。我已经用完整的控制台输出更新了主要问题。
而不是原生配置文件。您可以尝试使用dev 配置文件，例如spring.profiles.active=dev，并确保您到达正确的端点。

标签： spring spring-boot spring-cloud spring-cloud-config

【解决方案1】：

searchLocations 属性接受文件和/或子目录的位置。尝试spring.cloud.config.server.native.searchLocations=file://H:/opt/app/ 而不是spring.cloud.config.server.native.searchLocations=file://H:/opt/app/app.static.properties 并点击http://localhost:9090/config/default/master/app.static.properties

【讨论】：

我必须使用spring.cloud.config.server.native.searchLocations=file:///H:/opt/app/ 和您提供的 URL 才能使其正常工作。谢谢！
@hell_storm2004 是的，对于 Windows 机器，您必须添加一个额外的 /

【解决方案2】：

按照以下步骤，我得到了同样的错误。

应用属性如下：

spring.application.name=spring-cloud-config-server
server.port=8888
logging.level.web=DEBUG
spring.cloud.config.server.git.uri=file:///C:/Users/DELL/git-localconfig-repo

添加依赖：

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-bootstrap</artifactId>
</dependency>

在限制服务pom.xml 文件中

如果还是不行，请尝试删除limits-service.properties并创建一个新的，或者尝试创建limits-service-dev.properties、limits-service-prod.properties并通过URL调用它们http://localhost:8888/limits-service/dev并检查它们是否有效..

问题主要是我猜路径或文件名。
