java - 无法从Spring云配置服务器中的GIT读取属性源

Question

我无法从 git 读取属性在 spring-cloud-config-server ,

我有两个应用程序配置客户端和配置服务器，我想从配置客户端读取配置服务器 git 中存在的属性存储库。

请在下面找到我的代码:

配置客户端

ConfigClientApplication.java

@SpringBootApplication
public class ConfigClientApplication {

    public static void main(String[] args) {
        SpringApplication.run(ConfigClientApplication.class, args);
    }
}

消息资源.java

@RestController
@RequestMapping("/rest")
public class MessageResource {

    @Value("${message: Defalut Hello}")
    private String message;

    @GetMapping("")
    public String getMessage() {
        return message;
    }

}

bootstrap.properties

spring.application.name=config-client
server.port=8091
management.endpoints.web.exposure.include=*
spring.cloud.config.uri=http://localhost:8888

配置客户端.properties

message = Hello World

我已在定义的 git URL 中提交了此文件，但我无法在其余 API 中获取消息属性。

当我启动配置客户端应用程序时，它会访问配置服务器 URL 但返回默认属性，

这是我的客户端和服务器日志。

在这里我可以看到它是从不同的目录加载的，而不是从 bootstrap.properties 中定义的 GIT 存储库加载的，请帮助我。

提前致谢。

Answer 1

缺少添加 your repository config-client.properties，因为您有一个名为catalog-service.properties。

如果这对您有帮助，请告诉我。

已更新

此外，您还需要更新一些内容。

配置服务器

根据documentation配置名称必须与项目名称相同。

spring.config.name=config-server

配置客户端

将 application.properties 重命名为 bootstrap.properties，因为当您放置 bootstrap 时，会在应用程序上下文之前读取属性。
