如何使用日志记录和追踪来帮助调试Java函数？

import java.util.logging.Logger;

public class MyFunction {

    private static final Logger logger = Logger.getLogger(MyFunction.class.getName());

    public static void main(String[] args) {
        // 记录一条提示信息
        logger.info("函数开始执行");

        // 记录一条警告信息
        logger.warning("检测到潜在问题");

        // 记录一条错误信息
        logger.error("发生异常", new Exception("错误消息"));
    }
}

import com.google.cloud.functions.CloudEventsFunction;
import com.google.cloud.trace.v2.Span;
import com.google.cloud.trace.v2.SpanContext;
import com.google.cloud.trace.v2.SpanId;
import com.google.cloud.trace.v2.TraceContext;
import com.google.cloud.trace.v2.TraceId;
import com.google.cloud.trace.v2.TraceRecord;
import com.google.cloud.trace.v2.TraceServiceClient;
import com.google.cloud.trace.v2.TraceSpan;

public class MyTracedFunction implements CloudEventsFunction {

    private TraceServiceClient traceServiceClient;

    // 构造函数用于创建TraceServiceClient
    public MyTracedFunction() {
        // 在函数中使用TraceServiceClient时，需要进行认证
        // 参考：https://googleapis.dev/java/google-cloud-trace/latest/index.html
        traceServiceClient = TraceServiceClient.create();
    }

    @Override
    public void accept(CloudEvent event) {
        // 获取事件中的追踪信息
        SpanContext spanContext = TraceContext
            .newBuilder()
            .setTraceId(TraceId.of(event.getId()))
            .build();

        // 创建一个新的跟踪范围
        Span span = Span
            .newBuilder()
            .setSpanId(SpanId.create())
            .setName("my-function")
            .setSpanContext(spanContext)
            .build();

        try (TraceRecord traceRecord = TraceRecord.newBuilder().addSpans(span).build()) {
            // 在传递控制权给被追踪函数之前将跟踪记录发送到Stackdriver
            traceServiceClient.createTraceRecord(traceRecord);

            // 在这里将跟踪范围传递给要追踪的函数
        } finally {
            // 发送最后一个跟踪范围的结束时间
            traceServiceClient.createTraceRecord(TraceRecord.getDefaultInstance());
        }
    }
}
