在我将 spring webflux （spring boot 2.2.0.m3 到 2.2.2.RELEASE ）和 r2dbc （spring-data-r2dbc 1.0.0.M2 到 1.0.0.RELEASE ）和 r2dbc-postgresql （1.0 .0.M7 到 0.8.0.M8) 项目我不断收到此错误

java.lang.IllegalArgumentException: Identifier 'password' is not a valid identifier. Should be of the pattern '\$([\d]+)'.
at io.r2dbc.postgresql.ExtendedQueryPostgresqlStatement.getIndex(ExtendedQueryPostgresqlStatement.java:197) ~[r2dbc-postgresql-0.8.0.RC2.jar:0.8.0.RC2]

我失败的业务逻辑就像上面

public Mono<LoggedIn> login(LoginRequest request) {

return Hashing.hashPassword(request.getPassword())
    .flatMap(hashedPassword -> {
      log.info(hashedPassword);
      return userAccountRepository.findByUsernameAndPassword(request.getUsername(), hashedPassword);
    })
    .doOnError(throwable -> log.error(throwable.getMessage(), throwable))
    .doOnNext(userAccountEntity -> log.info("Login attempt : {}", userAccountEntity))
    .switchIfEmpty(Mono.error(ErrorHandlerFactory.newException(ErrorCode.USER_NOT_FOUND_ERROR)))
    .map(userAccount -> {
      String accessToken = util.generateToken(userAccount.getUuid(), Role.USER);
      return LoggedIn.builder()
          .name(userAccount.getFirstName())
          .surname(userAccount.getLastName())
          .profilePictureUrl(Optional.empty())
          .company(Company.builder().name("Netax AS").description("description here").build()) // todo fix here
          .accessToken(accessToken)
          .build(); // todo omitted feature
    });}

你能帮我找出为什么我会收到这个错误吗？

我得到了同样的错误。我不知道您的存储库是什么样的，但在我的：

@Query("select id, title from user where title ilike $1")
Flux<User> findAllSpecial(String title);

错误“java.lang.IllegalArgumentException：标识符'title'不是有效的标识符。应该是模式'\$（[\d]+）'。”

@Query("select id, title from user where title ilike :title")
Flux<User> findAllSpecial(String title);

作品。
