我在升级到新版本的Spring时遇到了问题。我有一个配置类WebSecurityConfig。我曾经从WebSecurityConfigurerAdapter继承它，但在Spring的新版本中，他们删除了它。你能告诉我如何为新版本的Spring重写这个类吗？我想在Spring版本3.1.2中重写此代码

package ua.com.alevel.config.security;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;

import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.security.web.util.matcher.AntPathRequestMatcher;

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    private final UserDetailsService userDetailsService;

    @Autowired
    public WebSecurityConfig(@Qualifier("userDetailsServiceImpl") UserDetailsService userDetailsService) {
        this.userDetailsService = userDetailsService;
    }

    @Bean
    public BCryptPasswordEncoder bCryptPasswordEncoder() {
        return new BCryptPasswordEncoder();
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                .csrf().disable()
                .authorizeRequests()
                .antMatchers("/**").permitAll()
                .antMatchers("/api/v1/user/getActualUser").permitAll()
                .anyRequest()
                .authenticated()
                .and()

                .invalidateHttpSession(true)
                .clearAuthentication(false)
                .deleteCookies("JSESSIONID")
                .logoutSuccessUrl("/user/loginUser");
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) {
        auth.authenticationProvider(daoAuthenticationProvider());
    }

    @Bean
    protected PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder(12);
    }

    @Bean
    protected DaoAuthenticationProvider daoAuthenticationProvider() {
        DaoAuthenticationProvider daoAuthenticationProvider = new DaoAuthenticationProvider();
        daoAuthenticationProvider.setPasswordEncoder(passwordEncoder());
        daoAuthenticationProvider.setUserDetailsService(userDetailsService);
        return daoAuthenticationProvider;
    }

    @Bean
    @Override
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }
}
