Thymeleaf href to controller : Could not parse as expression - spring-mvc

Question

I am using Thymleaf href inside a loop.
<th:block th:each="study : ${studyList}">
<tr>
<td th:text="${study.patient.name}"></td>
<td th:text="${study.status}"></td>
<td th:text="${study.description}"></td>
<td><a th:href="#{/updateStudy/{studyId} (studyId=${study.id})}>"</a>Update</td>
</tr>
</th:block>
And my controller definition is
#RequestMapping(value = "/updateStudy/{studyId}")
public void updateStudy(#RequestParam("studyId") long studyId
) {
....
}
The page is not rendering as I am getting parsing exception:
Could not parse as expression: "#{/updateStudy/{studyId}
(studyId=${study.id})}>"
Also in the html page it is complianing : Undefined attribute name ((studyId).
What I am missing here ? Kindly help.
UPDATE:
Apparently the expression should have been
<td><a th:href="#{/updateStudy/{studyId} (studyId=${study.id})}" >Update</a></td>
Now at least the parsing error is resolved. But I am getting this:
There was an unexpected error (type=Bad Request, status=400).
Required long parameter 'studyId' is not present
Hopefully it is not related to the href expression.
SOLVED
Just to complete the answer, I have changed the controller definition to
#GetMapping("/updateStudy/{studyId}")
public String updateSchedulePage(#PathVariable Long studyId, Model model) {
..}
And now everything works fine.

Answer 1

Try with this:
<td><a th:href="#{/updateStudy/${study.id}}" >Update</a></td>
Here is another problem in controller:
#RequestParam will be `#PathVariable `
Change to it:
#RequestMapping(value = "/updateStudy/{studyId}")
public void updateStudy(#PathVariable ("studyId") long studyId
) {
....
}
