Call REST API from Java

Question

I am trying to call JIRA REST API from Java function and I am not really sure how to do it.

Currently, I am using something like

String baseURL = ComponentAccessor.getApplicationProperties().getString(APKeys.JIRA_BASEURL);
String address = baseURL + "/rest/api/2/issue/" + issueID;
URL url = new URL(address);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod("GET");
conn.setRequestProperty("Accept", "application/json");

which fails on authorization (401). I have found some suggestions to include encoded login and password to the request, but I would like to use the current logged user.

I found some tutorials for JIRA REST Java Client, but cant seem to get it working.

Can someone point me out to some simple example of calling internal REST API using logged users credentials? If such thing is even possible.

For most cases, yes, but I am trying to create an entity link (link between a Jira project and a Confluence space) and the only way I found was through a private REST API.

@Mathieu YargeauI dont remember exactly, but I think you can access most of the data from internal APIs directly through some accessors (like pulling out an issue or list of custom fields).
