PlayFramework completely implements an APP (2)

1. Develop DataModel

Create a new User.java under appmoders

package models;

import java.util.*;
import javax.persistence.*;
import play.db.jpa.*;

@Entity
public class User extends Model {
public String email;
public String passWord;
public String fullname;
public String isAdmin;

public User(String email, String password, String fullname) {
this.email = email;
this.password = password;
this.fullname = fullname;
}
}

@Entity identifier is a JPA entity, inherited from play.db.jpa.Model, which provides fields of the JPA implementation

class, which will automatically Map to the DB table, the default indication is "User", if you want to modify the indication, add the label "@Table(name="blog_user")" to the class

2. Test

Run

> play test yape

or run in Eclipse, Test Yet Another Blog Engine

Visit http://localhost:9000/@tests, enter the test mode

Select Test, Start execution, success will be marked as Green, failure will prompt

3. Write test case

Modify /test/BasicTest.java

@Test
public void createAndRetrieveUser() {
  //Create a new user and save it
new User(" alex@Gmail.com", "####", "Alex").save();

//Retrieve the user with email address
User user = User.find("byEmail", "alex@gmail. com").first();

//Test
assertNotNull(user);
assertEquals("Alex", user.fullname);
}

Create User, find User, make assertions

User inherits from Model , provides savefind and other methods

User.java adds the connect method

public static User connect(String email, String passowrd) {
return find("byEmailAndPassword", email, passowrd).first();
}

　

Add test case

@Test
public void tryConnectAsUser() {
// Create a new user and save it
new User("bob@gmail.com", "####", "Bob" ) .save ();

// test
assertnotnull (user.connect ("bob@gmail.com", "####");
assertnull (user.connect ("bob@gmail.com", "$$$$"));
assertNull(User.connect("tom@gmail.com", "####"));
}
