java - 在 Controller 建议中获取 Controller 名称和java服务路径

Question

大家好，我在 Spring Boot 应用程序中创建了一个全局异常处理程序，并在下面的代码中编写了 AWS cloudwatch 中发生的异常，工作正常，我能够在 cloudwatch 中编写异常，但挑战是我无法获取 Restcontroller 名称以及发生特定异常的服务路径。

示例java服务

@GetMapping(value = "DynamoDb/deleteTable")
public String deleteTable(@RequestParam String TableName) throws InterruptedException {
     Table table = dynamoDB.getTable(TableName);
        try {
            table.delete();
            table.waitForDelete();
        } catch (Exception e) {
            throw e;
        }
        return "Success";
    }

当发生异常时，控制权会转移到controlleradvice全局异常处理程序

这是我的代码

有人可以帮助我如何在全局异常处理程序中获取 Restcontroller 名称和服务路径吗？

大家好，感谢大家使用下面的代码，我能够得到客户建议的结果。希望这可以帮助某人。谢谢

        DescribeLogStreamsRequest logStreamRequest = DescribeLogStreamsRequest.builder()
                .logGroupName(logGroupName)
                .logStreamNamePrefix(logStreamName)

        DescribeLogStreamsResponse describeLogStreamsResponse = logsClient.describeLogStreams(logStreamRequest);

        // Assume that a single stream is returned since a specific stream name was
        // specified in the previous request.
        return describeLogStreamsResponse.logStreams().get(0).uploadSequenceToken();
    }

}

结果应该是这样的

{
    "errorMessage": "Table already exists: ProductFgh (Service: AmazonDynamoDBv2; Status Code: 400; Error Code: ResourceInUseException; Request ID: 6S14VS0E6ESUMG55DL937IC42JVV4KQNSO5AEMVJF66Q9ASUAAJG)",
    "timeStamp": "2020-Jan-22 11:53:58",
    "errorCode": 500,
    "projectName": "DynamoDB",
    "servicePath": "http://localhost:8090/DynamoDb/createTable",
    "controllerName": "class com.example.DynamoDB.DynamoDBController",
    "serviceName": "createExampleTable"
}

到目前为止，我已经通过上面的代码实现了这一点，如果有更好的方法可用，请告诉我。感谢大家
