Spring Cloud Config客户端未从配置服务器加载配置 [英] spring cloud config client not loading configuration from config server

问题描述

我正在关注此链接: http://cloud.spring.io/spring-cloud-config/spring-cloud-config.html#_client_side_usage

我一遍又一遍地进行了测试，但没有看到Spring cloud客户端正在从云服务器加载配置，请帮助查看错误在哪里:

I tested this again and again and not seeing Spring cloud client is loading configuration from cloud server, please help to see where is the error:

POM:

<dependencies>
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter</artifactId>
    </dependency>

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>

    </dependency>
</dependencies>

应用程序:

@Configuration
@EnableAutoConfiguration
@RestController
public class ConfigclientApplication {
    
    @Value("${spring.cloud.config.uri}")
    String url;
    
    @Value("${production.host}")
    String host;
    
    
    @RequestMapping("/")
    public String home() {
        return "Host is  => " + this.host ;
    }
    
    public static void main(String[] args) {
        SpringApplication.run(ConfigclientApplication.class, args);
    }
}

bootstrap.properties:spring.cloud.config.uri = http://localhost:8888

bootstrap.properties: spring.cloud.config.uri=http://localhost:8888

1. 配置服务器很好:http://localhost:8888/spirent/default

{
  "name": "spirent",
  "profiles": [
    "default"
  ],
  "label": "master",
  "propertySources": [
    {
      "name": "classpath:/spirent.yml",
      "source": {
        "production.host": "server1",
        "production.port": 9999,
        "production.value1": 12345,
        "test.host": "server2.com",
        "test.port": 4444,
        "test.value": "hello123"
      }
    }
  ]
}

1. 现在完全无法启动http://localhost:8080/.

1. now http://localhost:8080/ can not be started at all.

创建名称为'configclientApplication'的bean时出错似乎@Value的自动注入无法找到production.host环境值.

Error creating bean with name 'configclientApplication' It seemed the auto inject of @Value can not find the production.host environment value.

从配置服务器加载后，如何读取客户端中的配置?

How can I read the configuration in client once loaded from config server?

感谢您的帮助.

推荐答案

正如Deinum所暗示的，我将确保您已将客户端配置为 parent 作为spring-cloud-starter-parent并给出它是一个版本.当您将Spring Cloud提供的依赖项包含在依赖项中时，请记住，Spring和boot是一个不同的项目，它将无法正常工作.更改为:

As Deinum implies, I'd ensure you have the client configured with the parent as spring-cloud-starter-parent and give it a version. Maven plugins provided by spring cloud wont work when you include in your dependencies and remember cloud is a different project than boot. Change it to:

<parent>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-parent</artifactId>
    <version>1.0.0.RELEASE</version>
    <relativePath /> <!-- lookup parent from repository -->
</parent>

第二，作为一门新学科(这里可能不是您的问题)，我将在您的应用程序上使用新注释，而不是@Configuration和@EnableAutoConfiguration

Second, as a new discipline (and likely not your problem here), I'd use the new annotation on your Application instead of @Configuration and @EnableAutoConfiguration

@SpringBootApplication

第三，再次检查您的配置服务器上是否有@EnableConfigServer

Third, double check you have @EnableConfigServer on your config server

第四，请确保您的客户端上的bootstrap.properties指定了您的spring应用程序名称:

Fourth, be sure your bootstrap.properties on your client has your spring application name specified:

spring.application.name=spirent

最后，如果您使用了spring-cloud-config示例项目，则必须在URI中设置默认的用户名和安全密码:

Finally, if you used the spring-cloud-config example project, there is a default user and security password that you have to set in your URI:

http://user:ddf4757e-0077-42e4-b2ad-2ae04340b08c@localhost:8888

否则，请尝试从此处的spring-cloud-config项目开始，以确保正确设置了配置服务器:

Otherwise, try starting from the spring-cloud-config project located here to ensure your config server is setup correctly:
