Spring Security -不能访问javax.servlet.Filter

Question

我正在使用Spring Security编写具有基本身份验证和授权的Spring Boot项目。我有一个扩展WebSecurityConfigurerAdapter的配置类(我想稍后去掉它，因为它已被弃用)。所以，我的配置类看起来像这样:

@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.inMemoryAuthentication().withUser("spring_user")
.password("password123")
.roles("ADMIN");
}
@Bean
public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
http
.authorizeHttpRequests((authz) -> authz.anyRequest().authenticated())
.httpBasic(Customizer.withDefaults());
return http.build();
}
@Bean
public static PasswordEncoder passwordEncoder() {
return new BCryptPasswordEncoder();
}
}

pom.xml文件:

注意我有spring-boot-starter-web依赖。

项目的其余部分没有什么有趣的。当我尝试运行应用程序时，显示以下消息:

java: cannot access javax.servlet.Filter
class file for javax.servlet.Filter not found

IDEA将我重定向到配置文件。(但没有一行代码用红色下划线)

这可能是什么原因?

Answer 1

所以，解决方案很简单。如果你要迁移到Spring 6，你应该放弃使用WebSecurityConfigurerAdapter类，而不是在没有它的情况下配置你的安全。

我已经写了一个新的配置(它做相同的操作以及在问题中提供的配置)，现在它看起来像这样:

@Configuration
@EnableWebSecurity
public class SpringSecurityConfig {
@Bean
public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {
http
.authorizeHttpRequests((authorize) -> authorize.anyRequest().authenticated())
.httpBasic(Customizer.withDefaults())
.formLogin(Customizer.withDefaults());
return http.build();
}
@Bean
public UserDetailsService userDetailsService() {
PasswordEncoder encoder = PasswordEncoderFactories.createDelegatingPasswordEncoder();
UserDetails user = User
.withUsername("spring_user")
.password(encoder.encode("password123"))
.roles("USER")
.build();
return new InMemoryUserDetailsManager(user);
}
}

这是Spring Security 6提供基本身份验证、默认密码编码器(建议使用)和内存用户所需的最小配置。
