java - How do I log response in Spring RestTemplate?

Question

I am using RestTemplate to make calls to a web service.

String userId = restTemplate.getForObject(createUserUrl, String.class);

If this fails to return a user ID I just get returned null but I don't know why. How do I output the actual XML response to a log?

Answer 1

Depending on which method of making the HTTP connection you are using, you could look at turning up the logging within the actual HTTP connection classes.

For example, if you are using commons HttpClient, you can set

log4j.logger.httpclient.wire=DEBUG

The commons-httpclient project has an entire page in the documentation on their logging practices.
