spring-cloud - Spring Cloud 配置客户端未从配置服务器中选择值
问题描述
我的配置客户端没有从配置服务器中选择属性值。
http://localhost:8888/customer_service/default
以上配置服务器端点正在为配置客户端返回正确的值,
{
"name": "customer_service",
"profiles": [
"default"
],
"label": null,
"version": "c7648db5662dc65aeaad9c91abbf58b41010be7c",
"state": null,
"propertySources": [
{
"name": "https://github.com/prasadrpm/MicroService_config.git/customer_service.properties",
"source": {
"customer.config.location": "XXXX",
"customer.config.name": "YYYY"
}
}
]
}
配置客户端 bootstrap.properties
server.port=8080
spring.application.name=customer_service
spring.cloud.config.enabled=true
spring.cloud.config.name=config_server
spring.cloud.config.uri=http://localhost:8888

解决方案
返回正确属性/配置的 URL 是:localhost:8888/customer_service/default
客户端应用程序正在根据以下数据查询属性:
c.c.c.ConfigServicePropertySourceLocator : Fetching config from server at : http://localhost:8888
c.c.c.ConfigServicePropertySourceLocator : Located environment: name=config_server, profiles=[default], label=null, version=c7648db5662dc65aeaad9c91abbf58b41010be7c, state=null
b.c.PropertySourceBootstrapConfiguration : Located property source: [BootstrapPropertySource {name='bootstrapProperties-configClient'}]
com.customer.CustomerServiceApplication : No active profile set, falling back to default profiles: default
...
因此,有效地,客户端应用程序正在调用:
localhost:8888/config_server/default
所以,有两种解决方案:
- 删除
spring.cloud.config.name=config_server
bootstrap.properties 中的属性,您的应用程序应该能够获取属性。 - 更新服务
spring.cloud.config.name
的价值customer_service
。但是如果您没有spring.cloud.config.name
明确提供,那么客户端将spring.application.name
使用spring.cloud.config.name
.
