Spring AuthenticationManager StackOverflowError with Kotlin - kotlin

Question

I have SecurityConfig for my application on Kotlin with Spring. So when I try to authenticate I get java.lang.StackOverflowError: null. I found it returns when runs this:
authenticationManager.authenticate(new
UsernamePasswordAuthenticationToken(authRequest.getUsername(), authRequest.getPassword()));
So this is my config.
#EnableWebSecurity
#EnableGlobalMethodSecurity(prePostEnabled = true)
class SecurityConfig() : WebSecurityConfigurerAdapter() {
#Override
override fun configure(http: HttpSecurity) {
http
.csrf().disable()
}
#Bean
fun passwordEncoder(): BCryptPasswordEncoder? = BCryptPasswordEncoder()
#Override
#Bean
override fun authenticationManagerBean(): AuthenticationManager =
super.authenticationManagerBean()
}
Ant this is exception:
java.lang.StackOverflowError: null

I found a lot of same problems but none of them have helped me.
Where the problem is?
The same config on Java work correctly

Answer 1

So, I solved my problem.
A basic authenticationManager check username and password
fun createAuthToken(#RequestBody authRequest: JwtRequest): ResponseEntity<Any?> {
try {
authenticationManager.authenticate(
UsernamePasswordAuthenticationToken(
authRequest.username,
authRequest.password
))
So it is necessary authenticationManager to know how to check username and password. We should override special method loadUserByUsername in UserService and make UserService extends UserDetailsService like this/
enter code here
#Override
#Transactional
override fun loadUserByUsername(username: String): UserDetails {
val user: User = findByUsername(username) ?: throw
UsernameNotFoundException(("User ${username} not found"))
return org.springframework.security.core.userdetails.User(
user.userName,
user.password,
mapRolesToAuthorities(user.getRoles())
)}
