The templates are quite flexible and you are not limited to one template
per path segment. You can have a templates like the following:
"{column1},{column2}"
"({column1},{column2})"
"[{column1}]:[{column2}]"
"1={column1},2={column2}"
Be careful of using the ';' because Jersey, by default, will think that
the path segment contains zero or more matrix parameters, and these will
be stripped from the path before matching occurs. This can be viewed as
a bug, templates with ';' should override matrix parameters, but off the
top of my head this might be rather tricky to fix (the workaround is to
turn off matrix param support by setting the feature to false in the
resource config).
