micrometer

对于那些关注此博客的人来说，难怪我会经常使用InfluxDB。 我喜欢这样一个事实，它是一个真正的单一用途的数据库（时间序列），具有许多功能，并且还带有企业支持。

Spring也是我选择的工具之一。 因此，在本博客中，我们将把spring与micrometer和InfluxDB集成在一起。

我们的应用程序将是用于工作的rest api。 最初，它会从GitHub的工作API如图所示取乔布斯[在这里][Link 1] 。

让我们从pom开始

             </dependency> 
        </dependencies>  </project>

让我们添加GitHub的Job Repository。

package com.gkatzioura.jobs.repository;  import java.util.List;  import org.springframework.http.HttpMethod;  import org.springframework.stereotype.Repository;  import org.springframework.web.reactive.function.client.WebClient;  import com.gkatzioura.jobs.model.Job;  import reactor.core.publisher.Mono;  @Repository  public class GitHubJobRepository { 
         private WebClient githubClient; 
         public GitHubJobRepository() { 
             this .githubClient = WebClient.create( " https://jobs.github.com " ); 
         } 
         public Mono<List<Job>> getJobsFromPage( int page) { 
             return githubClient.method(HttpMethod.GET) 
                                .uri( "/positions.json?page=" + page) 
                                .retrieve() 
                                .bodyToFlux(Job. class ) 
                                .collectList(); 
         }  }

工作模式

package com.gkatzioura.jobs.model;  import lombok.Data;  @Data  public class Job { 
         private String id; 
         private String type; 
         private String url; 
         private String createdAt; 
         private String company; 
         private String companyUrl; 
         private String location; 
         private String title; 
         private String description;  }

控制器

package com.gkatzioura.jobs.controller;  import java.util.List;  import org.springframework.web.bind.annotation.GetMapping;  import org.springframework.web.bind.annotation.PathVariable;  import org.springframework.web.bind.annotation.RequestMapping;  import org.springframework.web.bind.annotation.RestController;  import com.gkatzioura.jobs.model.Job;  import com.gkatzioura.jobs.repository.GitHubJobRepository;  import reactor.core.publisher.Mono;  @RestController  @RequestMapping ( "/jobs" )  public class JobsController { 
         private final GitHubJobRepository gitHubJobRepository; 
         public JobsController(GitHubJobRepository gitHubJobRepository) { 
             this .gitHubJobRepository = gitHubJobRepository; 
         } 
         @GetMapping ( "/github/{page}" ) 
         private Mono<List<Job>> getEmployeeById( @PathVariable int page) { 
             return gitHubJobRepository.getJobsFromPage(page); 
         }  }

最后但并非最不重要的主要应用程序。

com.gkatzioura; package com.gkatzioura;  import org.springframework.boot.SpringApplication;  import org.springframework.boot.autoconfigure.EnableAutoConfiguration;  import org.springframework.boot.autoconfigure.SpringBootApplication;  import org.springframework.boot.autoconfigure.security.reactive.ReactiveSecurityAutoConfiguration;  @SpringBootApplication  @EnableAutoConfiguration (exclude = { 
             ReactiveSecurityAutoConfiguration. class  })  public class Application { 
         public static void main(String[] args) { 
             SpringApplication.run(Application. class , args); 
         }  }

在下一个[博客中，][Link 2]我们将与InfluxDB和测微仪集成。
