如何在本地为AWS运行Java Lambda函数并使用无服务器（SLS）检查日志

Question

I know how to answer my question for python and nodejs.

It is simply: sls invoke local --function functionName for invocation and sls logs -f functionName to view logs. I am confused with java since function is inside class. Any suggestions is appreciated. Thanks.

Answer 1

I found the answer myself. I was looking for following: serverless.yml should contains something like:

functions:
  your-lambda-function-name:
    handler: package_name.class_name::lambda_method_name
    ...................................................
    ...................................................

then we can invoke:

sls invoke -f your-lambda-function-name

if we are using any stage like prod or nonprod then

sls invoke --stage prod/nonprod -f your-lambda-function-name

invoke with logs:

sls invoke -f your-lambda-function-name -l 

only for logs

sls logs -f your-lambda-function-name

or to monitor live

sls logs -f your-lambda-function-name -t
