无法使用Webflux在Spring Boot 2.x中通过repo-->delete删除文档

完整的源代码演示应用程序可以在这里看到github.com网站 Source code link

这是我的文档类:

@Document(collection = "users")
public class Employee implements Serializable {

    @Id
    private String id = UUID.randomUUID().toString();

    private String firstName;

    private String lastName;

    private String email;

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getFirstName() {
        return firstName;
    }

    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }

    public String getLastName() {
        return lastName;
    }

    public void setLastName(String lastName) {
        this.lastName = lastName;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }
}

 public Mono<ServerResponse> deleteAnEmployee(ServerRequest request) {
        String employeeId = request.pathVariable("id");
        return employeeRepository.findById(employeeId)
                .flatMap(employee -> {
                    employeeRepository.delete(employee);
                    return ServerResponse.ok().build();
                }).switchIfEmpty(ServerResponse.notFound().build());
    }

我是不是漏了什么suggest.pom路由器、repo等请参阅描述中提供的gihub链接。
