1.MVC 模式简介
MVC 模式代表 Model-View-Controller(模型-视图-控制器) 模式。这种模式用于应用程序的分层开发。
Model(模型):模型代表一个存取数据的对象或 JAVA POJO。它也可以带有逻辑,在数据变化时更新控制器。
View(视图):视图代表模型包含的数据的可视化。
Controller(控制器) :控制器作用于模型和视图上。它控制数据流向模型对象,并在数据变化时更新视图。它使视图与模型分离开。
2.示例Demo
class Student { private String name; private String number; public void setName(String name) { this.name = name; } public String getName() { return name; } public void setNumber(String number) { this.number = number; } public String getNumber() { return number; } } class StudentView { public void updateView(Student student) { System.out.println("Student:"); System.out.println("Name: " + student.getName()); System.out.println("Number: " + student.getNumber()); } } class StudentControler { private Student model; private StudentView view; public StudentControler(Student model, StudentView view) { this.model = model; this.view = view; } public void setStudentName(String name) { model.setName(name); } public String getStudentName() { return model.getName(); } public void setStudentNumber(String number) { model.setNumber(number); } public String getStudentNumber() { return model.getNumber(); } public void updateView() { view.updateView(model); } } public class MVCPatternDemo { public static void main(String args[]) { Student model = new Student(); model.setName("ZhangShan"); model.setNumber("123456789"); StudentView view = new StudentView(); StudentControler control = new StudentControler(model, view); control.updateView(); } }
