It appears you're not looking at the right place for the issue.
The logger outputs that you have an error with the request URI /users/1:
Request URI = /users/1
and your testing method is trying to get /account/1:
mockMvc.perform(get("/account/1"))
As for the error itself, MethodArgumentTypeMismatchException:
Exception that indicates that a method argument has not the expected type.
In other words, the method which is annotated by #GetMapping("/users/{id}") has the wrong #PathVariable parameter type.
In your case, you're using UUID as parameter:
public #ResponseBody ResponseEntity<AccountDTO> getAccount(#PathVariable UUID id) {
However, in your test, you're not passing a UUID, you're passing a numerical value (long/int) in your test.
If you want to generate a random UUID, you can use UUID.randomUUID():
#Test
public void getAccount()throws Exception {
mockMvc.perform(get("/account/" + UUID.randomUUID()))
.andDo(print())
.andExpect(status().isOk())
.andExpect(view().name("/account/"));
}
Alternatively, you could use long instead of uuid in your mapping method:
#GetMapping(value = "/{id}")
#ApiOperation(value = "Retrieve account.")
public #ResponseBody ResponseEntity<AccountDTO> getAccount(#PathVariable Long id) {
return accountService.retreiveById(id).map(ResponseEntity::ok)
.orElseGet(() -> ResponseEntity.notFound().build());
}
though in that case, you'll probably have to change your AccountService.retrieveById(id) method.
Good luck!
