No constructor find in...及NullPointerException错误

1.No constructor find in...错误

org.apache.ibatis.executor.ExecutorException: No constructor found in (....)

Users类代码如下：

public class User {    private Integer userId;    private String userName;    private String password;    private String name;    private String sex;    private String email;    public User(Integer userId, String userName, String password, String name, String sex, String email, Integer age,Integer tel, String locked, String del, Date createTm, String createPerson, Date updateTm,String updatePerson) {super();this.userId = userId;this.userName = userName;this.password = password;this.name = name;this.sex = sex;this.email = email;this.age = age;this.tel = tel;this.locked = locked;this.del = del;this.createTm = createTm;this.createPerson = createPerson;this.updateTm = updateTm;this.updatePerson = updatePerson;}

未找到合适的构造函数，

后加上空参构造器，即解决问题。

public User() {super();}

看别人的博客，有的说是int与Integer的问题。不知为何

2.NullPointerException

空指针错误，

1.有未赋值的内部成员

2.有未自动装配的成员变量，即未添加 @Autuwired注解
