最近,我开始使用spring cloud sleuth来跟踪应用程序中的请求,并编写了示例项目来测试此功能,但是当应用程序运行时,日志显示每个新的http请求都有不同的跟踪ID
这里可能是代码: Config.java
package com.cloud;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
@Configuration
@ComponentScan()
@EnableAutoConfiguration()
@EnableWebMvc
public class Config {
}
Controller.java
package com.cloud;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.cloud.sleuth.Span;
import org.springframework.cloud.sleuth.SpanAccessor;
import org.springframework.context.annotation.Bean;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.client.RestTemplate;
@RestController
public class Controller {
@Autowired
SpanAccessor spanAccessor;
@Autowired
RestTemplate restTemplate;
int port = 8080;
private static final Logger LOGGER = LoggerFactory.getLogger(Controller.class);
@RequestMapping("/")
public String hi() throws InterruptedException {
LOGGER.debug("you called hi");
debug();
String s = this.restTemplate
.getForObject("http://localhost:" + this.port + "/cloud/hi2", String.class);
return "hi/" + s;
}
@RequestMapping("/hi2")
public String hi2() throws InterruptedException {
LOGGER.debug("you called hi2");
debug();
return "welcome";
}
public void debug(){
Span span = spanAccessor.getCurrentSpan();
LOGGER.info("span id is "+span.getSpanId()+" and trace id is "+span.getTraceId());
}
@Bean
public RestTemplate restTemplate(){
return new RestTemplate();
}
}
这是log:
you called hi: span id is 6716502497271349964 and trace id is 6716502497271349964
you called hi2: span id is -4542377791493777157 and trace id is -4542377791493777157
答案 0 :(得分:1)
我复制/粘贴您的代码并且它有效,但我应该提一些差异:
首先也是最重要的,我当然是用一个主要的女巫和springboot anotation运行它:
@SpringBootApplication(scanBasePackages =" com.cloud&#34)
第二,我删除了你的Config类,因为它没有做任何事情。
三,mi spring版本的1.5.1.RELEASE和春云版本的Dalston.BUILD-SNAPSHOT这是日志:
