Why is my anchor tag in Thymeleaf is not redirecting to the local file - thymeleaf

Question

I am trying to redirect to another local web page using a tag in Thymeleaf and Spring boot but it is
not working. I am redirecting from index.html to addEdit.html which are in the same folder.
Here is my code.
index.html
<div class="container">
<p th:text="${message}"></p>
<a th:href="#{/addEdit.html}" class="btn btn-outline-info">Add Employee</a> //not working
<table class="table table-bordered table-dark">
<thead class="">
<tr>
<th>#</th>
<th>Name</th>
<th>Departmen</th>
<th>Position</th>
<th></th>
<th></th>
</tr>
</thead>
<tbody>
<tr th:each="employee : ${employees}" >
<th th:text="${employee.id}"></th>
<td th:text="${employee.name}"></td>
<td th:text="${employee.department}"></td>
<td th:text="${employee.position}"></td>
<td>
<form action="delete">
<input type="submit" value="Delete" class="btn btn-outline-warning"/>
</form>
</td>
<td>
<form action="edit">
<input type="submit" value="Edit" class="btn btn-outline-info"/>
</form>
</td>
</tr>
</tbody>
</table>
</div>
my EmployeeController
#Autowired
private employeeRepo repo;
#RequestMapping("/")
public String home(Model model) {
List<Employee> list = new ArrayList<>();
list = repo.findAll();
model.addAttribute("employees",list);
return "index";
}
#PostMapping("/addEmployee")
public void addEmployee(Employee employee,Model model) {
repo.save(employee);
model.addAttribute("message","Add Successfully");
home(model);
}
my addEdit.html
<div class="container bg-light">
<form action="addEmployee">
<input class="form-control form-control-sm" type="text" placeholder="Name" name="name"><br>
<input class="form-control form-control-sm" type="text" placeholder="Department" name="department"><br>
<input class="form-control form-control-sm" type="text" placeholder="Position" name="postion"><br/>
<input type="submit" value="Add Employee" class="btn btn-outline-success btn-lg btn-block">
</form>
</div>

Answer 1

You should not include the .html in your link. The link should point to a URL that your controller exposes. There is currently no controller method that exposes the /addEdit url for example.
So update your controller:
#GetMapping
public String addEmployee(Model model) {
// add model attributes here as needed first
return "addEdit" // This refers to the view, so 'addEdit.html'
}
Now update the link to:
<a th:href="#{/addEdit}" class="btn btn-outline-info">Add Employee</a>
