我收到以下错误
Caused by: java.lang.IllegalArgumentException: Could not resolve placeholder 'rate' in string value "${rate}"
at org.springframework.util.PropertyPlaceholderHelper.parseStringValue(PropertyPlaceholderHelper.java:174) ~[spring-core-4.3.5.RELEASE.jar:4.3.5.RELEASE]
at org.springframework.util.PropertyPlaceholderHelper.replacePlaceholders(PropertyPlaceholderHelper.java:126) ~[spring-core-4.3.5.RELEASE.jar:4.3.5.RELEASE]
使用的春季启动版本是
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.4.3.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
服务器的yml文件是
server:
port: 9000
spring:
cloud:
config:
server:
git:
uri: https://github.com/kswat/microservices
search-paths:
- 'station*'
服务器启动正常并在端口9000。
客户项目: 使用相同版本的弹簧靴。
spring:
application:
name: s1rates
profiles:
active: default
cloud:
config:
uri: http://localhost:9000
enabled: true
控制器代码:
@RestController
public class RateController {
@Value("${rate}")
String rate;
@RequestMapping("/rate")
public String getRate(){
return rate;
}
}
端口8888有限制吗? 为什么我的客户开始寻找8888

如果我在配置服务器中使用8888,那么客户端无一例外地干净地工作。 什么是8888魔法,为什么我必须坚持下去?是这个启动版本问题还是我的错误?

已解决 - 将云客户端项目application.yml文件名更改为bootstrap.yml 服务器端口9000工作
bootstrap.yml在application.yml

非常重要,客户端应用程序名称必须与存储库中的属性名称相同。例如,您的配置客户端应用程序名称为config-client,则存储库中的属性文件应为config-client-dev .properties。否则,您将收到“无法解析占位符$ {xxx}”错误。

使用 git 作为属性源的 Spring 云服务器以 git 风格与存储库一起工作,因此它可以使用不同的分支,以及关于该问题的重要事项 - 必须提交更改才能可见强>.
