Question

Currently I got the main class:

package com.recweb.springboot;

import org.springframework.boot.SpringApplication;
im         


        

Answer 1

@Override
public void configure(AuthenticationManagerBuilder auth) throws Exception{    
    auth.inMemoryAuthentication().passwordEncoder(NoOpPasswordEncoder.getInstance())
            .withUser("test").password("test123").roles("USER").and()
            .withUser("test1").password("test123").roles("ADMIN");
}

Answer 2

You need to set the password encoder like this:

@Bean
public PasswordEncoder passwordEncoder() {
  return PasswordEncoderFactories.createDelegatingPasswordEncoder();
}

It's required to use the passwordEncoder for the users and also for the clients in Spring Boot 2

Check out this repository https://github.com/dzinot/spring-boot-2-oauth2-authorization-jwt

You can see how the passwordEncoder is set up and how to use it with users and clients in the database.

Answer 3

I simply added

 @Bean
public static NoOpPasswordEncoder passwordEncoder() {
 return (NoOpPasswordEncoder) NoOpPasswordEncoder.getInstance();
}

To the configuration class
