springboot 项目添加jaeger调用链监控

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();

}
