Play Framework 完整实现一个APP（2）_.NET Framework

Play Framework 完整实现一个APP（二）

1.开发DataModel

在app\moders 下新建User.java

package models;import java.util.*;import javax.persistence.*;import play.db.jpa.*;@Entitypublic 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标识是一个JPA entity，继承自play.db.jpa.Model，提供了JPA实现

类的字段，会自动映射到DB表中，默认表明是"User"，如果要修改表明，在类上添加标签"@Table(name="blog_user")"

2.测试

运行

>play test yape

或在Eclipse中运行，Test Yet Another Blog Engine

访问 http://localhost:[email protected]，进入测试模式

选择Test, Start执行，成功会标记为绿色，失败会有提示

3.写测试用例

修改 /test/BasicTest.java

@Testpublic void createAndRetrieveUser() {    	//Create a new user and save it    	new User("[email protected]", "####", "Alex").save();    	    	//Retrieve the user with email address    	User user = User.find("byEmail", "[email protected]").first();    	    	//Test    	assertNotNull(user);    	assertEquals("Alex", user.fullname); }

创建User，查找User，进行断言

User继承自Model，提供了save\find等方法

User.java添加connect方法

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

添加测试用例

@Testpublic void tryConnectAsUser() {    	// Create a new user and save it    	new User("[email protected]", "####", "Bob").save();    	    	// Test         assertNotNull(User.connect("[email protected]", "####"));        assertNull(User.connect("[email protected]", "$$$$"));        assertNull(User.connect("[email protected]", "####"));}
