You can lookup the answers for this question: Spring security : migrating 4.0 to 5.0 - Error -There is no PasswordEncoder mapped for the id “null”

However, for Spring Security 5, the correct definition would be:

<bean id ="passwordEncoder" class = "org.springframework.security.crypto.password.NoOpPasswordEncoder" factory-method = "getInstance" />
