【问题描述】:
我收到以下错误
Caused by: java.lang.IllegalArgumentException: Could not resolve placeholder 'rate' in string value "${rate}"
at org.springframework.util.PropertyPlaceholderHelper.parseStringValue(PropertyPlaceholderHelper.java:174) ~[spring-core-4.3.5.RELEASE.jar:4.3.5.RELEASE]
at org.springframework.util.PropertyPlaceholderHelper.replacePlaceholders(PropertyPlaceholderHelper.java:126) ~[spring-core-4.3.5.RELEASE.jar:4.3.5.RELEASE]
使用的spring boot版本是
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.4.3.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
服务器的yml文件是
server:
port: 9000
spring:
cloud:
config:
server:
git:
uri: https://github.com/kswat/microservices
search-paths:
- 'station*'
服务器启动正常,在 9000 端口。
客户项目: 使用相同版本的 spring boot。
spring:
application:
name: s1rates
profiles:
active: default
cloud:
config:
uri: http://localhost:9000
enabled: true
控制器代码:
@RestController
public class RateController {
@Value("${rate}")
String rate;
@RequestMapping("/rate")
public String getRate(){
return rate;
}
}
8888端口有限制吗? 为什么我的客户从寻找 8888 开始
:: Spring Boot :: (v1.4.3.RELEASE)

如果我在配置服务器中使用 8888,那么客户端可以干净地工作,无一例外。 什么是 8888 魔法,为什么我必须坚持它?这是启动版本的问题还是我的错误?
