Service layer doesn't delete entity? - spring-boot

Question

I have a controller that must delete my entity:
#GetMapping ("/delete")
#PreAuthorize ("hasAuthority ('Admin')")
public String deleteStudent (Long studentId, String keyword) {
studentService.removeStudent(studentId);
return "redirect:/students/index?keyword="+keyword;
}
and HTML page that represent my entity:
<div class="container mt-3">
<div class="card-header">List of Students</div>
<div class="card-body">
<table class="table mt-3">
<thead>
<tr class="text-center">
<th>Student Id</th>
<th>Student First Name</th>
<th>Student Last Name</th>
<th>Student Level</th>
</tr>
</thead>
<tbody>
<tr class="text-center" th:each="student: ${list}">
<td th:text="${student.getStudentId()}"></td>
<td th:text="${student.getFirstName()}"></td>
<td th:text="${student.getLastName()}"></td>
<td th:text="${student.getLevel()}"></td>
<td>
<a onclick="confirm ('Are you sure')" class="btn btn-danger"
th:href="#{students/delete(studentId=${student.getStudentId()}, keyword=${keyword})}"> Delete </a>
</td>
</tr>
</tbody>
</table>
</div>
My Service
public interface StudentService {
void removeStudent (Long studentId);
I run application, open http://localhost:8071/students/index everything work okay, but when I delete my entity I'm getting:
ERROR PAGE There was an unexpected error (type=Not Found, status=404).
-> http://localhost:8071/students/students/delete?studentId=1&keyword=

Answer 1

You have students duplicated in the path, hence 404:
http://localhost:8071/students/students/delete
Your line
th:href="#{students/delete(studentId=${student.getStudentId()}, keyword=${keyword})}"
Should be:
th:href="#{delete(studentId=${student.getStudentId()}, keyword=${keyword})}"
