所以我正在使用Spring和JWT进行身份验证，但是当我创建//类时遇到了这个错误，我做了一些研究，但是没有什么对我有用
这是一个类：
@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class WebSec extends WebSecurityConfigurerAdapter {
@Autowired
private JwtAuthenticationEntry jwtAuthenticationEntry;
@Autowired
private JwtRequestFilter jwtRequestFilter;
@Autowired
private UserDetailsService jwtService;
@Bean
@Override
public AuthenticationManager authenticationManagerBean() throws Exception{
return super.authenticationManagerBean();
}
@Override
protected void configure(HttpSecurity httpSecurity) throws Exception{
httpSecurity.cors();
httpSecurity.csrf().disable()
.authorizeHttpRequests().antMatchers("/authen").permitAll()
.antMatchers(HttpHeaders.ALLOW).permitAll()
.anyRequest().authenticated()
.and()
.exceptionHandling().authenticationEntryPoint(jwtAuthenticationEntry)
.and()
.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);
httpSecurity.addFilterBefore(jwtRequestFilter, UsernamePasswordAuthenticationFilter.class);
}
@Bean
public PasswordEncoder passwordEncoder(){
return new BCryptPasswordEncoder();
}
@Autowired
public void configure(AuthenticationManagerBuilder authenticationManagerBuilder) throws Exception{
/*this*/authenticationManagerBuilder.userDetailsService(jwtService).passwordEncoder(passwordEncoder());
}
}这是错误，它说我在一行中有错误，我用双斜线划了它

您没有显示JwtRequestFilter的源代码。该异常意味着您注入到WebSec中的其中一个bean对WebSec具有间接依赖性。例如，它可以是：
你能做什么？
我建议将WebSec中没有明确使用的东西移到一个单独的类中：
passwordEncoder()configure(AuthenticationManagerBuilder)或者，您可以对会导致循环引用的bean使用惰性初始化，但是循环依赖可能会在以后导致新的问题。
除此之外，还有另一个问题：bean WebSec提供了一个类型为PasswordEncoder的bean，但在方法
configure()中，您直接调用方法passwordEncoder()。因此，在某些地方，您将拥有一个由Spring控制的bean，在其他地方，您将只有一个Java对象。在这种特定情况下，这不会导致问题。但在其他情况下，它可能会。例如，如果您使用AOP来修改某些bean的行为，它将仅应用于Spring bean，而不是不使用Spring创建的普通Java对象。
