在控制器建议中获取控制器名称和 java 服务路径
Get controller name and java service path in controller advice
大家好我已经在我的 spring 启动应用程序中创建了一个全局异常处理程序，并将异常发生在 AWS cloudwatch 中写入下面的代码工作正常我能够在 cloudwatch 中写入异常但挑战是我无法从发生特定异常的位置获取 Restcontroller 名称和服务路径。
样本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";
}
每当发生异常时，控制权都会转移到 controlleradvice 全局异常处理程序
这是我的代码

任何人都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？
您可以获取引发异常的 class 名称，如下所示：
ex.getStackTrace()[0].getClassName();
