spring-boot-starter-graphql: getting 404 for /graphql endpoint - spring-boot

Question

I am using the new Spring for Graphql in my Spring Boot application. My problem is, that the server always responds 404 when making a POST request to the /graphql endpoint.
These are my gradle dependencies
implementation 'org.springframework.boot:spring-boot-starter-data-jpa'
implementation 'org.springframework.boot:spring-boot-starter-graphql'
implementation 'org.springframework.boot:spring-boot-starter-mail'
implementation 'org.springframework.boot:spring-boot-starter-security'
implementation 'org.springframework.boot:spring-boot-starter-validation'
implementation 'org.springframework.boot:spring-boot-starter-web'
implementation 'org.springframework.boot:spring-boot-starter-websocket'
implementation 'org.flywaydb:flyway-core'
compileOnly 'org.projectlombok:lombok'
runtimeOnly 'org.postgresql:postgresql'
annotationProcessor 'org.projectlombok:lombok'
I followed the steps in this tutorial to create the controllers (formerly known as resolvers, I actually changed all my old Graphql resolvers to the new #QueryMapping and #MutationMapping annotations)
This is the code for my StepController
#Slf4j
#Controller
#RequiredArgsConstructor
public class StepController {
private final StepService stepService;
private final TokenService tokenService;
#QueryMapping
public ArrayList<Step> getSteps(String templateId) {
return stepService.getSteps(templateId);
}
#MutationMapping
public Step createStep(StepInput input, DataFetchingEnvironment env) {
return stepService.createStep(input, tokenService.getUserId(env));
}
}
I am also using WebSecurity in my project, changed my deprecated WebSecurityConfigurerAdapter to the more modern way of doing this by creating a Bean inside a SecurityConfig.class
#Configuration
public class SecurityConfiguration {
#Bean
public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
http.cors()
.configurationSource(request -> {
var cors = new CorsConfiguration();
cors.setAllowedOrigins(List.of("http://localhost:4200", "electron://altair"));
cors.setAllowedMethods(List.of("GET", "POST", "DELETE", "OPTIONS"));
cors.setAllowedHeaders(List.of("*"));
cors.setAllowCredentials(true);
return cors;
})
.and()
.csrf().disable()
.authorizeRequests()
.antMatchers(HttpMethod.POST, "/graphql").permitAll()
.antMatchers(HttpMethod.GET, "/stomp/**").permitAll()
.anyRequest().authenticated()
.and()
// this disables session creation on Spring Security
.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);
return http.build();
}
}
My GraphQl Schema is structured in resources/graphql in a folder structure, I had no problem with this before I switched to the new Spring Boot Graphql
UPDATE To be on the safe side: I deleted the whole folder structure and replaced it with one schema.graphqls file that has just the Login mutation and a query that is never used, just to avoid the Query needed compiler error
type Mutation {
login(email: String!, password: String!): Login!
}
type Login {
token: String
}
// unused, just to make the compiler happy
type Query {
getLogin: Login
}
application.properties
spring.banner.location=classpath:logo.txt

spring.output.ansi.enabled=ALWAYS
spring.main.allow-bean-definition-overriding=true
spring.mail.host=mail.blablabla

I hope I provided enough information as to how my project is set up. I would really appreciate any help that can solve this issue. I searched the whole evening yesterday, finally now posting this question here. I hope someone can help me. Thanks

Please add this property in application.properties file and try again.
spring.graphql.graphiql.enabled=true
