Spring Cloud配置客户端未从配置服务器中拾取值

Question

My Config客户端没有从配置中拾取属性值服务器

http://localhost:8888/customer_service/default 

上述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"
}
}
]
}

配置客户端引导程序.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

Answer 1

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基于以下数据查询属性：

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，实际上，客户端应用程序正在调用：

localhost:8888/config_server/default 

因此，有两种解决方案：

• 删除bootstrap.properties中的spring.cloud.config.name=config_server属性，您的应用程序应该能够获取属性
• 将CCD_ 3的值更新为CCD_。但若并没有显式地提供spring.cloud.config.name，那个么客户端将使用spring.application.name作为spring.cloud.config.name的默认值

Answer 2

您在这里使用了什么注释？这样可以很容易地检索到它。

@Value("${customer.config.location}")
private String someOtherProperty;

并且不需要

spring.cloud.config.name=config_server
