目前在zipkin brave已经提供功能在我们使用logback或log4j等时可以在日志信息中将traceId和spanId等信息打印到运行日志，这样可能对我们通过日志查看解决问题有比较大的帮助。
示例：
pom.xml中添加zipkin相关jar
<dependency>
<groupId>io.zipkin.brave</groupId>
<artifactId>brave-instrumentation-spring-web</artifactId>
<version>5.4.3</version>
</dependency>
<dependency>
<groupId>io.zipkin.brave</groupId>
<artifactId>brave</artifactId>
<version>5.4.3</version>
</dependency>
<dependency>
<groupId>io.zipkin.brave</groupId>
<artifactId>brave-context-slf4j</artifactId>
<version>5.4.3</version>
</dependency>
<dependency>
<groupId>io.zipkin.brave</groupId>
<artifactId>brave-instrumentation-spring-webmvc</artifactId>
<version>5.4.3</version>
</dependency>
注入zip相关bean：
Configuration
@Import({
TracingClientHttpRequestInterceptor.class,
SpanCustomizingAsyncHandlerInterceptor.class
})
public class TracingConfiguration extends WebMvcConfigurerAdapter {
@Bean
public DelegatingTracingFilter getDelegatingTracingFilter() {
return new DelegatingTracingFilter();
}
@Bean
Sender sender() {
return OkHttpSender.create("http://127.0.0.1:9411/api/v2/spans");
}
@Bean
AsyncReporter<Span> spanReporter() {
return AsyncReporter.create(sender());
}
@Bean
Tracing tracing(@Value("${zipkin.service:brave-webmvc-example}") String serviceName) {
return Tracing.newBuilder()
.localServiceName(serviceName)
.propagationFactory(ExtraFieldPropagation.newFactory(B3Propagation.FACTORY, "user-name"))
.spanReporter(spanReporter()).currentTraceContext(ThreadLocalCurrentTraceContext.newBuilder()
//添加日志相关的处理器
.addScopeDecorator(MDCScopeDecorator.create()).build()).build();
}
@Bean
HttpTracing httpTracing(Tracing tracing) {
return HttpTracing.create(tracing);
}
@Autowired
TracingClientHttpRequestInterceptor clientInterceptor;
@Bean
public RestTemplate restTemplate() {
RestTemplate restTemplate = new RestTemplate();
List<ClientHttpRequestInterceptor> interceptors =new ArrayList<>(restTemplate.getInterceptors());
interceptors.add(clientInterceptor);
restTemplate.setInterceptors(interceptors);
return restTemplate;
}
@Autowired
SpanCustomizingAsyncHandlerInterceptor serverInterceptor;
@Override
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(serverInterceptor);
}
}
运行日志：
@RequestMapping("start")
public String start(HttpServletRequest request1,HttpServletResponse response1) throws InterruptedException, IOException {
logger.info("start");
String data = restTemplate.getForObject("http://localhost:9090/foo", String.class);
return data;
}
logback.xml相关配置：
主要添加这个打印格式：
<property name="CONSOLE_LOG_PATTERN" value="%d [%X{traceId}/%X{spanId}] [%thread] %-5level %logger{36} - %msg%n"/>
logback.xml示例：
<?xml version="1.0" encoding=www.dasheng178.com/"UTF-8"?>
<configuration>
<include resource="org/springframework/boot/logging/logback/defaults.xml"/>
<springProperty scope="context" name="springAppName" source="spring.application.name"/>
<!-- Example for logging into the build folder of your project -->
<property name="LOG_FILE" value="logs\\${springAppName}.log"/>?
<!-- You can override this to have a custom pattern www.mcyllpt.com-->
<property name="CONSOLE_LOG_PATTERN" value="%d [%X{traceId}/%X{spanId}] [%thread] %-5level %logger{36} - %msg%n"/>
<!-- Appender to log to console -->
<appender name="console"www.ysyl157.com class="www".hjylp178.com"ch.qos.logback.core.ConsoleAppender">
<filter class="ch.qos.logback.classic.filter.ThresholdFilter">
<!-- Minimum logging level to be presented in the console logs-->
<level>INFO</level>
</filter>
<encoder>
<pattern>${CONSOLE_LOG_PATTERN}</pattern>
<charset>utf8</charset>
</encoder>
</appender>
<!-- Appender to log to file -->?
<appender name=www.yigouyule2.cn "flatfile" class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>${LOG_FILE}</file>
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<fileNamePattern>${LOG_FILE}.www.hengy178.com%d{yyyy-MM-dd}.gz</fileNamePattern>
<maxHistory>7</maxHistory>
</rollingPolicy>
<encoder>
<pattern>${CONSOLE_LOG_PATTERN}</pattern>
<charset>utf8</charset>
</encoder>
</appender>
<root level="INFO"www.120xh.cn>
<appender-ref ref="console"/>
<!-- uncomment this to have also JSON logs -->
<appender-ref ref="flatfile"/>
</root>
</configuration>
日志打印信息：
2018-10-20 21:24:28,656 [af49581a0f632677/af49581a0f632677] [http-nio-8080-exec-1] INFO c.t.controller.HomeController - start
