POST request with multipart data in spring webflux - spring-boot

Question

i am working with spring webflux when i added security to my app,the multipart or payload data on POST request coudnt be found in the controller, you can find below my security configuration class and my custom webfilter class
import java.util.Collections;
import org.springframework.context.annotation.Bean;
import org.springframework.security.config.annotation.method.configuration.EnableReactiveMethodSecurity;
import org.springframework.security.config.annotation.web.reactive.EnableWebFluxSecurity;
import org.springframework.security.config.web.server.SecurityWebFiltersOrder;
import org.springframework.security.config.web.server.ServerHttpSecurity;
import org.springframework.security.web.server.SecurityWebFilterChain;
import org.springframework.security.web.server.csrf.CookieServerCsrfTokenRepository;
import org.springframework.web.cors.CorsConfiguration;
import org.springframework.web.cors.reactive.CorsConfigurationSource;
import org.springframework.web.cors.reactive.UrlBasedCorsConfigurationSource;
#EnableWebFluxSecurity
#EnableReactiveMethodSecurity
public class SecurityConfiguration {
#Bean
public SecurityWebFilterChain securityWebFilterChain(ServerHttpSecurity http) {
// #formatter:off
return http
.csrf()
.csrfTokenRepository(CookieServerCsrfTokenRepository.withHttpOnlyFalse())
.and().addFilterBefore( new CustomWebFilter(), SecurityWebFiltersOrder.ANONYMOUS_AUTHENTICATION)
.authorizeExchange()
.pathMatchers("/ws/**").permitAll()
.anyExchange().authenticated()
.and()
.oauth2Login()
.and()
.oauth2ResourceServer()
.jwt().and().and().build();
// #formatter:on
}
#Bean
CorsConfigurationSource corsConfigurationSource() {
CorsConfiguration configuration = new CorsConfiguration();
configuration.setAllowCredentials(true);
configuration.setAllowedOrigins(Collections.singletonList("http://localhost:4200"));
configuration.addAllowedMethod(CorsConfiguration.ALL);
configuration.setAllowedHeaders(Collections.singletonList("*"));
UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
source.registerCorsConfiguration("/**", configuration);
return source;
}
}
this is my custom webfilter class
i made a cutom filter for multipart filter to integrate it in spring security chain but the problem is that the filter is servlet based
import org.springframework.core.Ordered;
import org.springframework.core.annotation.Order;
import org.springframework.stereotype.Component;
import org.springframework.web.multipart.support.MultipartFilter;
import org.springframework.web.server.ServerWebExchange;
import org.springframework.web.server.WebFilter;
import org.springframework.web.server.WebFilterChain;
import lombok.extern.slf4j.Slf4j;
import reactor.core.publisher.Mono;
#Component
#Order(Ordered.HIGHEST_PRECEDENCE)
#Slf4j
public class CustomWebFilter implements WebFilter {
#Override
public Mono<Void> filter(ServerWebExchange exchange, WebFilterChain chain) {
log.info("My Custom Web Filter.");
new MultipartFilter();//java.lang.NoClassDefFoundError: javax/servlet/Filter
return chain.filter(exchange);
}
}
this is the original error that is raised when i call the controller to save a file
