SpringCloud整合skywalking实现链路追踪和日志采集

1.部署skywalking

https://blog.csdn.net/qq_40942490/article/details/144701194

2.添加依赖

        <!-- 日志采集 --><dependency><groupId>org.apache.skywalking</groupId><artifactId>apm-toolkit-logback-1.x</artifactId><version>9.3.0</version></dependency><!-- 自定义链路追踪 《如果不需要就会用默认的》 --><dependency><groupId>org.apache.skywalking</groupId><artifactId>apm-toolkit-trace</artifactId><version>9.3.0</version></dependency>

3.增加日志配置文件

增加logback-spring.xml文件：

文件内容如下：

<?xml version="1.0" encoding="UTF-8"?>
<configuration scan="false" scanPeriod="10 seconds"><contextName>logback</contextName><property name="log.path" value="./log/bztc-study01"/><!--1. 输出到控制台--><appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender"><encoder class="ch.qos.logback.core.encoder.LayoutWrappingEncoder"><layout class="org.apache.skywalking.apm.toolkit.log.logback.v1.x.TraceIdPatternLogbackLayout"><Pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%tid] [%thread] %-5level %logger{36} -%msg%n</Pattern></layout></encoder></appender><root level="info"><appender-ref ref="STDOUT"/></root>
</configuration>

4.打印日志

其中，TID需要打印出来

5. windos环境–在IDEA中配置SkyWalking

下载地址 https://skywalking.apache.org/downloads/

在运行的程序配置jvm参数，如下图所示：

-javaagent:C:\Users\admin\Downloads\skywalking-agent\skywalking-agent.jar
-Dskywalking.agent.service_name=portrait-model
-Dskywalking.collector.backend_service=172.16.2.43:11800

6.skywalking网页查询链路

在搜索框中查询TID：

7.自定义链路追踪

7.1代码中使用traceId

@RequestMapping("/list")
public List<User> list(){//TraceContext可以绑定key-valueTraceContext.putCorrelation("name", "fox");Optional<String> op = TraceContext.getCorrelation("name");log.info("name = {} ", op.get());//获取跟踪的traceIdString traceId = TraceContext.traceId();log.info("traceId = {} ", traceId);return userService.list();
}

7.2@Trace 将方法加入追踪链路

调用链路中显示返回值，以及参数值信息，使用@Tag或者@Tags
@Tag注解中key=方法名 value=returnedObj 返回值 agr[0] 参数
param标识参数，returnedObj标识返回值

    @RequestMapping("/add")@Trace@Tag(key = "add",value ="returnedObj")public String add() {System.out.println("下单成功");// String forObject = restTemplate.getForObject("http://localhost:8083/stock/reduct", String.class);String forObject = restTemplate.getForObject("http://stock-service/stock/reduct", String.class);//int a= 1/0;return "add order " + forObject;}@RequestMapping("/getById/{id}")@Trace@Tags({@Tag(key = "getById",value ="returnedObj"),@Tag(key="param",value = "arg[0]")})public String getById(@PathVariable("id") Integer id) {return "根据id获取信息";}

8.日志收集

<?xml version="1.0" encoding="UTF-8"?>
<configuration scan="false" scanPeriod="10 seconds"><contextName>logback</contextName><property name="log.path" value="./log/bztc-study01"/><!--1. 输出到控制台--><appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender"><encoder class="ch.qos.logback.core.encoder.LayoutWrappingEncoder"><layout class="org.apache.skywalking.apm.toolkit.log.logback.v1.x.TraceIdPatternLogbackLayout"><Pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%tid] [%thread] %-5level %logger{36} -%msg%n</Pattern></layout></encoder></appender><!--2. 日志收集--><appender name="grpc-log" class="org.apache.skywalking.apm.toolkit.log.logback.v1.x.log.GRPCLogClientAppender"><encoder class="ch.qos.logback.core.encoder.LayoutWrappingEncoder"><layout class="org.apache.skywalking.apm.toolkit.log.logback.v1.x.mdc.TraceIdMDCPatternLogbackLayout"><Pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%X{tid}] [%thread] %-5level %logger{36} -%msg%n</Pattern></layout></encoder></appender><root level="info"><appender-ref ref="STDOUT"/><appender-ref ref="grpc-log"/></root>
</configuration>

9.重新启动服务 然后查看skywalking网页的Log
