java-返回 traceID 与 本机ip

1. pom依赖

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-sleuth</artifactId>
    <version>2.2.2.RELEASE</version>
</dependency>

2. 代码

2.1. 获取traceId逻辑

使用该依赖所加载的bean:

同时tracer.currentSpan().context().traceId()返回的traceId是十进制，最后只要转成十六进制就可以了。

package org.example.config;


import brave.Tracer;
import cn.hutool.core.util.ObjectUtil;
import lombok.extern.slf4j.Slf4j;
import org.example.util.IpUtil;
import org.example.vo.LogTracerVo;
import org.springframework.stereotype.Component;


import javax.annotation.Resource;


/**
* @author 杨镇宇
* @date 2024/11/26 10:48
* @version 1.0
*/
@Component
@Slf4j
public class LogTracer {


    @Resource
    private Tracer tracer;


    public LogTracerVo getTrace(){
        String traceId = ObjectUtil.isNotNull(tracer.currentSpan()) ? Long.toHexString(tracer.currentSpan().context().traceId()) :"no traceId";
        String hostAddress = IpUtil.getIp();
        return LogTracerVo.builder().traceId(traceId).ip(hostAddress).build();
    }
}

2.2. 对于获取本机ip逻辑

package org.example.util;


import java.io.BufferedReader;
import java.io.InputStreamReader;


/**
* Utility class for retrieving the local machine's IP address.
* Supports both Linux and Windows environments.
*
* @author 杨镇宇
* @date 2024/11/26 10:42
* @version 1.0
*/
public class IpUtil {


    private static class SingleIpUtil {


        private static String getIp() {


            String ip = "";
            try {
                String os = System.getProperty("os.name").toLowerCase();
                Process process;
                boolean linuxFlag = os.contains("nix") || os.contains("nux") || os.contains("mac");


                if (os.contains("win")) {
                    // Windows system: use ipconfig command
                    process = Runtime.getRuntime().exec("ipconfig");
                } else if (linuxFlag) {
                    // Linux or macOS system: use hostname -I command
                    process = Runtime.getRuntime().exec("hostname -I");
                } else {
                    return "Unsupported OS";
                }


                // Read the output with correct encoding (GBK for Windows)
                BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream(), "GBK"));
                String line;
                boolean found = false;
                while ((line = reader.readLine()) != null) {
                    if (os.contains("win") && line.contains("IPv4")) {
                        // Extract the IPv4 address from the line containing "IPv4"
                        ip = line.split(":")[1].trim();
                        found = true;
                        break;
                    }
                    // On Linux/macOS, get the first non-empty line
                    if (linuxFlag && !line.trim().isEmpty()) {
                        ip = line.trim();
                        found = true;
                        break;
                    }
                }
                if (!found) {
                    return "IP address not found.";
                }
                System.out.println("Current IP Address: " + ip);
                return ip;
            } catch (Exception e) {
                e.printStackTrace();
                return "Error fetching IP";
            }
        }
    }


    private IpUtil() {
        // Prevent instantiation
    }


    public static String getIp() {
        return SingleIpUtil.getIp();
    }
}

package org.example.vo;


import lombok.*;


/**
* @author 杨镇宇
* @date 2024/11/26 10:49
* @version 1.0
*/
@Data
@Builder
@AllArgsConstructor
@NoArgsConstructor
@EqualsAndHashCode(callSuper = false)
public class LogTracerVo {
    private String traceId;
    private String ip;
}
