Take the student information management system as an example to demonstrate the addition, deletion, modification and query of student information. Here, the student's Bean class is defined as:

Student.java

Public class Student {

Private String studentId

Private String name

Private int weight

Private int height

Private Date birthday

Public String getStudentId () {

Return studentId

}

Public void setStudentId (String studentId) {

This.studentId = studentId

}

Public String getName () {

Return name

}

Public void setName (String name) {

This.name = name

}

Public int getWeight () {

Return weight

}

Public void setWeight (int weight) {

This.weight = weight

}

Public int getHeight () {

Return height

}

Public void setHeight (int height) {

This.height = height

}

Public Date getBirthday () {

Return birthday

}

Public void setBirthday (Date birthday) {

This.birthday = birthday

}

@ Override

Public String toString () {

Return "Student [studentId=" + studentId + ", name=" + name

+ ", weight=" + weight + ", height=" + height + ", birthday="

+ birthday + "]"

}

Public Student (String studentId, String name, int weight, int height

Date birthday) {

Super ()

This.studentId = studentId

This.name = name

This.weight = weight

This.height = height

This.birthday = birthday

}

Public Student () {

}

}

The API for adding, deleting, modifying and querying students is defined as follows:

IStudentDao.java

Public interface IStudentDao {

Void insert (Student s)

Void update (Student s)

Void delete (String studentId)

}

The API implementation file for manipulating MongoDB is as follows

IStudentDaoImpl.java

Public class IStudentDaoImpl implements IStudentDao {

@ Override

Public void insert (Student s) {

/ / not implemented yet

}

@ Override

Public void update (Student s) {

/ / not implemented yet

}

@ Override

Public void delete (String studentId) {

/ / not implemented yet

}

}
