我目前正在开发一个Web应用程序，我在Sping Boot 中为后端编写Java程序。我正在尝试配置Spring Security，以便只有拥有JWT-Token的用户才能访问任何端点。我甚至不确定这是否是问题所在，但每次启动应用程序时，我都会收到以下错误：

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.springframework.security.config.annotation.web.configuration.WebSecurityConfiguration': Unsatisfied dependency expressed through method 'setFilterChains' parameter 0: Error creating bean with name 'securityFilterChain' defined in class path resource [com/myapp/backend/config/SecurityConfiguration.class]: Failed to instantiate [org.springframework.security.web.SecurityFilterChain]: Factory method 'securityFilterChain' threw exception with message: Cannot invoke "Object.getClass()" because "filter" is null

编译器将以下代码标记为已弃用：

package com.myapp.backend.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.authentication.AuthenticationProvider;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;

import org.springframework.security.config.http.SessionCreationPolicy;
import org.springframework.security.web.SecurityFilterChain;
import org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter;

import jakarta.servlet.Filter;
import lombok.RequiredArgsConstructor;

@Configuration
@EnableWebSecurity
@RequiredArgsConstructor
public class SecurityConfiguration {

    private AuthenticationProvider authenticationProvider;
    private JwtAuthenticationFilter jwtAuthFilter;

    @Bean
    public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {
        http
        .csrf()
        .disable()
        .authorizeHttpRequests()
        .requestMatchers("/auth/**")
        .permitAll()

        .and()
        .authenticationProvider(authenticationProvider)
        .addFilterBefore(jwtAuthFilter,  UsernamePasswordAuthenticationFilter.class);
                
        return http.build();
    }
}
