从java调用RestAPI :找不到UsernamePasswordAuthenticationToken的AuthenticationProvider

@Configuration
@EnableWebSecurity

    private CustomAuthenticationProvider authenticationProvider;

    @Override

                .antMatchers("/api/**").authenticated()
                .and()
                .httpBasic();
    }
}

@Component
public class CustomAuthenticationProvider implements AuthenticationProvider {

    @Override
    public Authentication authenticate(Authentication authentication) throws AuthenticationException {
        String username = authentication.getName();
        String password = authentication.getCredentials().toString();

        // 在此处进行自定义的身份验证逻辑

        return new UsernamePasswordAuthenticationToken(username, password, new ArrayList<>());
    }

    @Override
    public boolean supports(Class<?> authentication) {
        return authentication.equals(UsernamePasswordAuthenticationToken.class);
    }
}
