1、spring boot客戶端git

一、在spring boot的項目pom.xml添加依賴github

<dependency>
    <groupId>io.opentracing.contrib</groupId>
    <artifactId>opentracing-spring-web-autoconfigure</artifactId>
    <version>0.0.4</version>
</dependency>

<!--添加jaeger-->
<dependency>
    <groupId>com.uber.jaeger</groupId>
    <artifactId>jaeger-core</artifactId>
    <version>0.21.0</version>
</dependency>

注入jaeger beanweb

@Bean
public io.opentracing.Tracer jaegerTracer() {
    return new Configuration("spring-boot", new Configuration.SamplerConfiguration(ProbabilisticSampler.TYPE, 1),
        new Configuration.ReporterConfiguration())
        .getTracer();

其中須要指定jaeger IP地址，默認是localhostspring

若是要修改地址docker

Configuration.SamplerConfiguration(ProbabilisticSampler.TYPE, 1, "jaeger IP地址:端口")

Configuration.ReporterConfiguration(
        false,
        "jaeger agent host",
        "jaeger agent port(int)",
        1000,
        100)

編寫測試 HelloController.javaapp

@RestController
public class HelloController {

    @Autowired
    private RestTemplate restTemplate;

    @RequestMapping("/hello")
    public String hello() {
        return "Hello from Spring Boot!";
    }

    @RequestMapping("/chaining")
    public String chaining() {
        ResponseEntity<String> response = restTemplate.getForEntity("http://localhost:8080/hello", String.class);
        return "Chaining + " + response.getBody();
    }
}

運行jaeger，以docker形式運行maven

docker run --rm -it --network=host jaegertracing/all-in-one

訪問:http://localhost:16686查看ui頁面spring-boot

運行spring boot程序post

訪問:http://localhost:8080/hello 和 http://localhost:8080/chaining

查看UI頁面，能夠看到

2、若是是spring cloud程序

則替換maven

<dependency>
   <groupId>io.opentracing.contrib</groupId>
   <artifactId>opentracing-spring-cloud-starter</artifactId>
   <version>0.0.4</version>
</dependency>


<!--添加jaeger-->
<dependency>
    <groupId>com.uber.jaeger</groupId>
    <artifactId>jaeger-core</artifactId>
    <version>0.21.0</version>
</dependency>

一樣方式運行
