阿里云-接入SLS日志

地址：

https://sls.console.aliyun.com/lognext/profile

创建project（存储日志的位置）

接入数据

java应用的业务日志

java应用集成LogService的SDK，上报日志

配置Slf4j的日志直接写入到SLS

配置日志（直接把日志写入到SLS）

获取traceId

package org.draymond.arms.utils;

import jakarta.servlet.http.HttpServletRequest;

import cn.hutool.core.lang.UUID;
import com.alibaba.arms.tracing.Span;
import com.alibaba.arms.tracing.Tracer;
import org.apache.commons.lang3.StringUtils;
public class TraceIdUtil {

    public static String getTraceIdHttpRequest(HttpServletRequest request) {
        Span span = Tracer.builder().getSpan();
        String traceId = span.getTraceId();
        if (StringUtils.isNotBlank(traceId)) {
            return traceId;
        } else {
            traceId = StringUtils.isBlank(request.getHeader("trace_id")) ? request.getHeader("traceId") : request.getHeader("trace_id");
            return StringUtils.isNotBlank(traceId) ? traceId : UUID.fastUUID().toString();
        }
    }

    public static String getTraceId() {
        Span span = Tracer.builder().getSpan();
        String traceId = span.getTraceId();
        return StringUtils.isNotBlank(traceId) ? traceId : UUID.fastUUID().toString();
    }
}

业务使用

@Slf4j
@Component
public class ArmsService {


    /**
     * 测试cpu占用
     *
     * @param number
     * @return
     */
    public ArmsModel cpuTest(Integer number) {
        MDC.put("traceId", TraceIdUtil.getTraceId());
        log.info("cpu测试, number={}", number);
        sleepNumberTime(number);
        ArmsModel build = ArmsModel.build(number);
        return build;
    }

}

SLS效果

后续可以根据traceId查询分布式日志

arms中使用traceId查询调用链

全链路
