为ID“ null”映射的PasswordEncoder

Question

我正在SpringBoot中进行CORS，并遇到了一系列问题，这些问题可以通过导入1个依赖项来解决。

public class ServiciosConfig  extends WebSecurityConfigurerAdapter {

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

    @Override

                .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");

    }

}

起初我错了，但是我用

解决了

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

因为他说他在进口某件商品时遇到了问题...

事实是，添加依赖项后，更新项目，然后执行并得到：

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

There was an unexpected error (type=Internal Server Error, status=500).
There is no PasswordEncoder mapped for the id "null"

我尝试过：

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

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

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

    }

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