1.添加maven依赖
<dependency>
<groupId>io.opentracing.contrib</groupId>
<artifactId>opentracing-spring-cloud-starter</artifactId>
<version>0.1.8</version>
</dependency>
<dependency>
<groupId>com.uber.jaeger</groupId>
<artifactId>jaeger-core</artifactId>
<version>0.26.0</version>
</dependency>
<dependency>
<groupId>com.uber.jaeger</groupId>
<artifactId>jaeger-b3</artifactId>
<version>0.26.0</version>
</dependency>
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
<version>4.5.5</version>
</dependency>
2.启动类 application添加bean
注意：http://192.168.181.99:30668/api/traces 为对应的jaeger collector地址
service-c 为服务名称
@Bean
public io.opentracing.Tracer jaegerTracer() {
Reporter reporter = new RemoteReporter.Builder().withFlushInterval(10)
.withMaxQueueSize(65000)
.withSender(new HttpSender("http://192.168.181.99:30668/api/traces"))
.withMetrics(new Metrics(new NoopMetricsFactory()))
.build();
Builder builder = new Builder("service-c")
.withReporter(reporter)
.withSampler(new ConstSampler(true))
.registerInjector(Format.Builtin.HTTP_HEADERS, new B3TextMapCodec())
.registerExtractor(Format.Builtin.HTTP_HEADERS, new B3TextMapCodec());
return builder.build();
}
