I'm doing the CORS in SpringBoot and I've had a series of problems that I solved by importing 1 dependency.

The pom.xml:

  <!-- Spring Boot -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-core</artifactId>
    <version>5.0.0.RELEASE</version>
 </dependency>
      <!-- JPA Data -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-jpa</artifactId>
        </dependency>

           <!-- MySQL Connector-J -->
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <scope>runtime</scope>
        </dependency>

        <dependency>
            <!-- Tomcat embedded container -->
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-tomcat</artifactId>
            <scope>provided</scope>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-devtools</artifactId>
            <optional>true</optional>
        </dependency>

          <!-- Data REST -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-rest</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-jdbc</artifactId>
        </dependency>


        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-security</artifactId>
        </dependency>
    </dependencies>

And WebSecurityConfigurerAdapter

package com.service.configure;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.PropertySource;
import org.springframework.http.HttpMethod;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.builders.WebSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.config.http.SessionCreationPolicy;

@Configuration
@EnableWebSecurity
@ComponentScan(basePackages = "com.service")

public class ServiciosConfig  extends WebSecurityConfigurerAdapter {

    //@Value("${usrRest}")
   // private String usrRest; 

    //@Value("${passRest}")
   // private String passRest; 
    //@PropertySource("file:${ruta_properties}")

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.csrf().disable();
        http.authorizeRequests().antMatchers("/").permitAll().anyRequest().authenticated().and().httpBasic().and()
                .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);
    }

    @Override

    public void configure(WebSecurity web) throws Exception {
        web.ignoring().antMatchers(HttpMethod.OPTIONS);
    }



    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
        auth.inMemoryAuthentication().withUser("admin").password("admin").roles("USER");

    }

}

At the beginning I got an error, but I solved it with

 <dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-core</artifactId>
    <version>5.0.0.RELEASE</version>
 </dependency>

Because he said he had problems with one of the imports ...

The fact is that after adding that dependency, update the project, I execute and I get:

java.lang.IllegalArgumentException: There is no PasswordEncoder mapped for the id "null"

On the web:

Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

@Autowired

    auth.inMemoryAuthentication().withUser("admin").password("admin").roles("USER");

}

for

@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
    auth.userDetailsService(userDetailsService());

}
@Bean
@Override
public UserDetailsService userDetailsService() {
    UserDetails user =
            User.withDefaultPasswordEncoder()
                    .username("admin")
                    .password("admin")
                    .roles("USER")
                    .build();

    return new InMemoryUserDetailsManager(user);
}

Explanation:

The InMemoryUserDetailsManager is responsible for the creation of users by you through its constructor:

 public InMemoryUserDetailsManager(UserDetails... users) {
    UserDetails[] var2 = users;
    int var3 = users.length;

    for(int var4 = 0; var4 < var3; ++var4) {
        UserDetails user = var2[var4];
        this.createUser(user);
    }

}
