为什么 bootstrap.properties 被 spring-cloud-starter-config 忽略?
Why bootstrap.properties is ignored by spring-cloud-starter-config?
我的目标是从 config-service
.
获取 world-service
的配置
架构:
config-service
依赖于 spring-cloud-config-server
在 localhost:8888
world-service
依赖 spring-web
和 spring-cloud-starter-config
.
我做了什么:
- 我已设置配置服务器并向
http://localhost:8888/hello-service/master
发送 GET 请求,配置服务器从 the config-repo repository. (If you need the config-service
's source code, I will push it to this repository 获取 hello-service.properties
。)
我的预期结果:
world-service
使用端口 8081。
我的实际结果:
world-service
使用端口 8080。
bootstrap.properties
spring.application.name=world-service
spring.cloud.config.uri=http://localhost:8888

在 Spring Cloud 2020 中,他们改变了 bootstrap 的工作方式,您必须包括一个新的入门者:spring-cloud-starter-bootstrap
.
折腾了一天,终于找到了解决办法。它可能会帮助其他人
您需要添加新的依赖项
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-bootstrap</artifactId>
</dependency>
Bootstrap, provided by spring-cloud-commons, is no longer enabled by
default. If your project requires it, it can be re-enabled by
properties or by a new starter.
To re-enable by properties set spring.cloud.bootstrap.enabled=true or
spring.config.use-legacy-processing=true. These need to be set as an
environment variable, java system property or a command line argument.
The other option is to include the new spring-cloud-starter-bootstrap
(in your POM file).
我使用了第一个选项并且对我有用。
Spring Boot 2.4 引入了一种通过 spring.config.import 属性 导入配置数据的新方法。这是现在绑定到配置服务器的默认方式。
要连接到配置服务器,请在 application.yml 中设置以下内容:
spring:
application:
name: APPLICATION_NAME
config:
import: optional:configserver:http://USER:PASSWORD@MY_HOST:PORT/
