Question

在具有反应性并使用jwt的spring boot应用程序中，在我的spring-cloud-gateway中，我有此代码。

@EnableDiscoveryClient
@SpringBootApplication
public class GatewayServiceApplication {

    public static void main(String[] args) {
        SpringApplication.run(GatewayServiceApplication.class, args);
    }

}

@Configuration
@EnableWebFluxSecurity
@EnableReactiveMethodSecurity
public class SpringSecurityWebFluxConfig {

    private final UserServiceImpl userService;
    private final JwtTokenUtil tokenUtil;

    private static final String[] AUTH_WHITELIST = {
        "/resources/**",
        "/webjars/**",
        "/authorize/**",
        "/favicon.ico"};


    public SpringSecurityWebFluxConfig(JwtTokenUtil tokenUtil, UserServiceImpl userService) {
        this.tokenUtil = tokenUtil;
        this.userService = userService;
    }
    ..
}

@Service
public class UserServiceImpl implements ReactiveUserDetailsService, UserService {

    private final UserRepository userRepository;

    public UserServiceImpl(final UserRepository userRepository) {
        this.userRepository = userRepository;
    }
    ...

}

@Repository
public interface UserRepository extends ReactiveCrudRepository<User, Integer>{
}

public class JWTHeadersExchangeMatcher implements ServerWebExchangeMatcher {
    @Override
    public Mono<MatchResult> matches(final ServerWebExchange exchange) {
    }
}

public class JWTReactiveAuthenticationManager implements ReactiveAuthenticationManager {
    ...

    public JWTReactiveAuthenticationManager(final PasswordEncoder passwordEncoder, final UserServiceImpl userService) {
        this.passwordEncoder = passwordEncoder;
        this.userService = userService;
    }
}


public class JwtTokenUtil {
    ...
}

public class TokenAuthenticationConverter implements Function<ServerWebExchange, Mono<Authentication>> {
     private final JwtTokenUtil tokenProvider;

    public TokenAuthenticationConverter(JwtTokenUtil tokenProvider) {
        this.tokenProvider = tokenProvider;
    }
}

public class TokenAuthenticationConverter implements Function<ServerWebExchange, Mono<Authentication>> {
     private final JwtTokenUtil tokenProvider;

    public TokenAuthenticationConverter(JwtTokenUtil tokenProvider) {
        this.tokenProvider = tokenProvider;
    }
}

试图将其自动接线

在SpringSecurityWebFluxConfig类中的UserServiceImpl上
在UserServiceImpl类的UserRepository上
在JWTReactiveAuthenticationManager.class的UserServiceImpl上

但出现相同错误

编辑

如果我使用

@ EnableR2dbcRepositories到GatewayServiceApplication，我没有此错误，但它搜索有关DatabaseClient的信息

Answer 1

请在UserServiceImpl类中为构造函数或变量级别中的UserRepository变量添加@Autowired注释。

通过带有userRepository的构造函数参数1表示的不满意依赖性
