Spring boot

Hi, I am a beginner at Spring Boot and I tried to configure my API espcially for user connexion. I have a database which is connected and it works. But I try to create a SecurityConfig and I have this error : java: variable userService not initialized in the default constructor In the code (after this message), I use @RequiredArgsConstructor so it should work... I have a problem with the model User for the database because it says it doesnt find getters but I use @Data with Loombook and it works on another model. Can someone please try to explain me ?

                        authorizeRequests.requestMatchers(
                                "/api/users/login",
                                "/api/users/register"
                        ).permitAll().anyRequest().authenticated())
                .build();
    }

    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }

        DaoAuthenticationProvider daoAuthenticationProvider = new DaoAuthenticationProvider();
        daoAuthenticationProvider.setUserDetailsService(userService);
        daoAuthenticationProvider.setPasswordEncoder(passwordEncoder);
        return new ProviderManager(daoAuthenticationProvider);

        /*

        auth.userDetailsService(userService).passwordEncoder(passwordEncoder);
        return auth.build();

        if (user == null) {
            throw new UsernameNotFoundException("User not found with email: " + username);
        }
        return new org.springframework.security.core.userdetails.User(
                user.getEmail(),

can you show your lombok configuration in pom

MaxenceOP•2w ago

message.txt

MaxenceOP•2w ago

on another model, @Data works but not with User

ayylmao123xdd•2w ago

what if instead of data you use @Getter @Setter @NoArgsConstructor @AllArgsConstructor

MaxenceOP•2w ago

Oh I just realize that I don't use getters with the other model so I can't have this error I try I have to put the four ?

ayylmao123xdd•2w ago

yes comment out @data and put these four and if that doesnt work

MaxenceOP•2w ago

it doesnt change anything

ayylmao123xdd•2w ago

 <path>
                            <groupId>org.projectlombok</groupId>
                            <artifactId>lombok</artifactId>
                            <version>${org.projectlombok.version}</version>
                        </path>

 <path>
                            <groupId>org.projectlombok</groupId>
                            <artifactId>lombok</artifactId>
                            <version>${org.projectlombok.version}</version>
                        </path>

in your annotation processor path add the version tags

 <properties>
        <org.projectlombok.version>1.18.30</org.projectlombok.version>
    </properties>

 <properties>
        <org.projectlombok.version>1.18.30</org.projectlombok.version>
    </properties>

add to properties maybe that is the problem

MaxenceOP•2w ago

here ?

ayylmao123xdd•2w ago

yea and in properties add this

  <org.projectlombok.version>1.18.30</org.projectlombok.version>

  <org.projectlombok.version>1.18.30</org.projectlombok.version>

and reload the project

MaxenceOP•2w ago

MaxenceOP•2w ago

I don't understand why I didn't have this, because when I create my project with IntellJ, I choose Lombok, so why it doesnt add all the dependencies need ? thanks

ayylmao123xdd•2w ago

MaxenceOP•2w ago
