代码：UserDaoImplementation

Question

我正在尝试登录但无法登录，因为在DAOimplementation中findOne查询失败。我放了一系列system.out.println来看看哪里出了问题。

我得到了这个

email: abcdef Password : 123123

email2: abcdef Password2: 123123

check 1

check 2

由于某种原因，程序不会达到检查3，检查4和内部是否条件用户！= null。

我尝试使用mongoTemplate，mongoOperations，使用addCriteria而没有条件，但没有运气。

使用适当的Java（Beans）命名约定：

首字母小写的CamelCase：

public User(String id, long userId, String firstname, String lastname, String email, String password, String role, long countryCode, long mobileNumber, String city, String address) 
{
  super();
  this.id = id;
  this.userId = userId;
  this.firstname = firstname;
  this.lastname = lastname;
  this.email = email;
  this.password = password;
  this.role = role;
  this.countryCode = countryCode;
  this.mobileNumber = mobileNumber;
  this.city = city;
  this.address = address;
}

Getter和Setter应为字段名称，首字母大写，并以get或set为前缀（如果存在）。

查询/字符串中引用的属性与字段名称相同。

注意：实际Java Bean规范存在一些偏差，例如：没有默认构造函数的选项。
