X-Ray跟踪未显示内部方法调用。

为要检测的每个方法启用X-Ray分析，以及在代码中添加子段落。

以下是一些代码示例：

在Lambda函数中，为每个方法启用X-Ray：

import com.amazonaws.xray.AWSXRay; import com.amazonaws.xray.entities.Subsegment;

public void lambdaHandler(Request request, Context context) { Subsegment subsegment = AWSXRay.beginSubsegment("handler"); try { handleRequest(request); } catch (Exception e) { subsegment.addException(e); } finally { AWSXRay.endSubsegment(); } }

在方法中添加子段落：

import com.amazonaws.xray.AWSXRay; import com.amazonaws.xray.entities.Subsegment;

public void handleRequest(Request request) { Subsegment subsegment = AWSXRay.beginSubsegment("handleRequest"); try { doSomething(); } catch (Exception e) { subsegment.addException(e); } finally { AWSXRay.endSubsegment(); } }

public void doSomething() { Subsegment subsegment = AWSXRay.beginSubsegment("doSomething"); try { // code here } catch (Exception e) { subsegment.addException(e); } finally { AWSXRay.endSubsegment(); } }
