First, build the project
case this paper there are three main project components: a server-zipkin, its main role using ZipkinServer functions, collect call data and display; a service-hi, the external exposure hi interfaces; a service-miya, Foreign miya exposed interfaces; both service can call each other; and only called, server-zipkin will collect the data, which is why the calls traced. Learn springcloud architecture can be added to beg: Er Siqi Liu Er San Sanwu Wujiu
Second, to build server-zipkin
build a spring-boot project named server-zipkin, introducing rely on its pom:
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
<dependency>
<groupId>io.zipkin.java</groupId>
<artifactId>zipkin-server</artifactId>
</dependency>
<dependency>
<groupId>io.zipkin.java</groupId>
<artifactId>zipkin-autoconfigure-ui</artifactId>
</dependency>
</dependencies>
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-dependencies</artifactId>
<version>Camden.SR6</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
Program entry in its class, annotate @EnableZipkinServer, open ZipkinServer features:
@SpringBootApplication
@EnableZipkinServer
public class ServerZipkinApplication {
public static void main(String[] args) {
SpringApplication.run(ServerZipkinApplication.class, args);
}
}
In the configuration file application.yml designated port for the service:
server.port=9411
Third, create a service-hi
incorporated start dependent spring-cloud-starter-zipkin thereon pom, code is as follows:
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<!--compile('org.springframework.cloud:spring-cloud-starter-zipkin')-->
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-zipkin</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
</dependencies>
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-dependencies</artifactId>
<version>Dalston.RC1</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
Specified in its configuration file application.yml zipkin server address, by arranging the head "spring.zipkin.base-url" specifies:
@SpringBootApplication
@EnableZipkinServer
public class ServerZipkinApplication {
public static void main(String[] args) {
SpringApplication.run(ServerZipkinApplication.class, args);
}
}
By introducing a spring-cloud-starter-zipkin provided spring.zipkin.base-url and dependent on it.
External exposure Interface:
@SpringBootApplication
@RestController
public class ServiceHiApplication {
public static void main(String[] args) {
SpringApplication.run(ServiceHiApplication.class, args);
}
private static final Logger LOG = Logger.getLogger(ServiceHiApplication.class.getName());
@Autowired
private RestTemplate restTemplate;
@Bean
public RestTemplate getRestTemplate(){
return new RestTemplate();
}
@RequestMapping("/hi")
public String callHome(){
LOG.log(Level.INFO, "calling trace service-hi ");
return restTemplate.getForObject("http://localhost:8989/miya", String.class);
}
@RequestMapping("/info")
public String info(){
LOG.log(Level.INFO, "calling trace service-hi ");
return "i'm service-hi";
}
@Bean
public AlwaysSampler defaultSampler(){
return new AlwaysSampler();
}
}
Fourth, the service-miya creating
process of creating pain service-hi, introduced into the same dependence configuration spring.zipkin.base-url.
External exposure Interface:
@SpringBootApplication
@RestController
public class ServiceMiyaApplication {
public static void main(String[] args) {
SpringApplication.run(ServiceMiyaApplication.class, args);
}
private static final Logger LOG = Logger.getLogger(ServiceMiyaApplication.class.getName());
@RequestMapping("/hi")
public String home(){
LOG.log(Level.INFO, "hi is being called");
return "hi i'm miya!";
}
@RequestMapping("/miya")
public String info(){
LOG.log(Level.INFO, "info is being called");
return restTemplate.getForObject("http://localhost:8988/info",String.class);
}
@Autowired
private RestTemplate restTemplate;
@Bean
public RestTemplate getRestTemplate(){
return new RestTemplate();
}
}
Specified in its configuration file application.yml zipkin server address, by arranging the head "spring.zipkin.base-url" specifies:
server.port=8988
spring.zipkin.base-url=http://localhost:9411
spring.application.name=service-hi
By introducing a spring-cloud-starter-zipkin provided spring.zipkin.base-url and dependent on it.
External exposure Interface:
@SpringBootApplication
@RestController
public class ServiceHiApplication {
public static void main(String[] args) {
SpringApplication.run(ServiceHiApplication.class, args);
}
private static final Logger LOG = Logger.getLogger(ServiceHiApplication.class.getName());
@Autowired
private RestTemplate restTemplate;
@Bean
public RestTemplate getRestTemplate(){
return new RestTemplate();
}
@RequestMapping("/hi")
public String callHome(){
LOG.log(Level.INFO, "calling trace service-hi ");
return restTemplate.getForObject("http://localhost:8989/miya", String.class);
}
@RequestMapping("/info")
public String info(){
LOG.log(Level.INFO, "calling trace service-hi ");
return "i'm service-hi";
}
@Bean
public AlwaysSampler defaultSampler(){
return new AlwaysSampler();
}
}
Start project, demonstration track
in turn starts the above three projects, open the browser to access: http: // localhost: 9411 / , will appear the following interface:
Access: http: // localhost: 8989 / miya, the browser appears:
i’m service-hi
Then open http: // localhost: 9411 / interface, click Dependencies, dependency services can be found:
Click find traces, you can see specific data service call each other:
