在Netbeans中使用Maven项目使用jUnit测试检查JDBC查找时出错

我试图为使用jdbc资源的文件创建一个测试。除了当我试图测试使用实体管理器的东西时，定期测试在整个项目中都能正常工作。我想我错过了一些简单的东西，并希望得到任何帮助。在Netbeans中使用Maven项目使用jUnit测试检查JDBC查找时出错

这是错误。

Feb 27, 2012 3:04:44 PM com.sun.enterprise.v3.server.ApplicationLifecycle deploy 
SEVERE: javax.naming.NamingException: Lookup failed for 'jdbc/foundation' in SerialContext[myEnv={com.sun.enterprise.connectors.jndisuffix=__pm, java.naming.factory.initial=com.sun.enterprise.naming.impl.SerialInitContextFactory, java.naming.factory.state=com.sun.corba.ee.impl.presentation.rmi.JNDIStateFactoryImpl, java.naming.factory.url.pkgs=com.sun.enterprise.naming} [Root exception is javax.naming.NameNotFoundException: foundation not found]

下面是一些我所采取的故障排除步骤：

添加了GlassFish群众演员Maven的POM
我已经把持久性文件中都/主/资源/测试/资源文件夹。
我已经尝试在DonationsFacadeTest文件的@BeforeClass方法中的上下文对象中添加属性，以及大约一百万种与下面类似的其他配置。

环境信息：

使用NetBeans 7.0.1
Maven项目
Glassfish的3.1

DonationsFacade.java - 这个类使用一个门面模式，以提供间接访问JPA实体。

@Stateless 
public class DonationsFacade extends AbstractFacade<Donations> { 
@PersistenceContext(unitName = "FoundationPU") 
private EntityManager em; 

protected EntityManager getEntityManager() { 
    return em; 
} 

public DonationsFacade() { 
    super(Donations.class); 
} 

public boolean setPaid(int id, String transId) 
{ 
    try{ 
     Donations don = em.find(Donations.class, id); 
     don.setStatus("Paid"); 
     don.setConfirmationnumber(transId); 
     em.persist(don); 
     em.flush(); 
     return true; 
    } 
    catch(Exception ex) 
    { 
     return false; 
    } 
}

测试文件 - 试图写一个简单的测试来验证数据。

public class DonationsFacadeTest { 

@Test 
public void testSetPaid() throws Exception { 
    int id = 1; 
    String transId = "123"; 
    EJBContainer ejbC = EJBContainer.createEJBContainer(); 
    Context ctx = ejbC.getContext();  
    DonationsFacade instance = (DonationsFacade)ctx.lookup("java:global/classes/DonationsFacade"); 
    boolean expResult = false; 
    boolean result = instance.setPaid(id, transId); 
    assertEquals(expResult, result); 
    ejbC.close(); 
} 
}

的persistence.xml

<?xml version="1.0" encoding="UTF-8"?> 
<persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence"...> 
    <persistence-unit name="FoundationPU" transaction-type="JTA"> 
    <jta-data-source>jdbc/foundation</jta-data-source> 
    <properties/> 
    </persistence-unit> 
</persistence>

与GlassFish resources.xml中

<resources> 
<jdbc-resource enabled="true" jndi-name="jdbc/foundation" object-type="user" pool-name="mysql_foundation_rootPool"> 
<description/> 
</jdbc-resource>

</jdbc-connection-pool> 
</resources>

再次感谢您的帮助，非常感谢。

Glassfish是否在执行测试时运行？什么是JNDI提供者？ – duffymo 2012-02-27 23:33:06

是的，glassfish正在运行。我认为这只是典型的MySQL jdbc提供程序。 – JCab 2012-02-27 23:36:59

不，JNDI命名服务是Glassfish的一部分。你如何告诉一个没有运行Glassfish的应用程序，比如你的单元测试，使用Glassfish JNDI命名服务？ – duffymo 2012-02-27 23:41:38

这里找出答案。我基本上把一个实体管理员注入了课堂。希望这对试图做同样事情的人有帮助。

public class DonationsFacadeTest { 


private EntityManager em; 
private EntityTransaction tx; 
DonationsFacade donations; 

public DonationsFacadeTest() { 
} 

@Before 
public void setUpClass() throws Exception { 

    EntityManagerFactory emf = Persistence.createEntityManagerFactory("Foundation2"); 
    em = emf.createEntityManager(); 
    tx = em.getTransaction(); 
    this.donations = new DonationsFacade(); 
    this.donations.em = em; 
} 

/** 
* Test of setPaid method, of class DonationsFacade. 
*/ 
@Test 
public void testSetPaid() throws Exception { 

    int id = 1; 
    String transId = "123"; 

    boolean expResult = false; 
    boolean result = donations.setPaid(id, transId); 
    assertEquals(expResult, result); 

} 
}

相应地修改了persistence.xml文件。

<persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence" ... > 
<persistence-unit name="Foundation2" transaction-type="RESOURCE_LOCAL"> 
    <class>org.scmc.foundation.session.DonationsFacadeTest</class> 
    <exclude-unlisted-classes>true</exclude-unlisted-classes> 
    <properties> 
     <property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver" /> 
     <property name="javax.persistence.jdbc.url" value="jdbc:mysql://localhost:3306/foundation"/> 
     <property name="javax.persistence.jdbc.user" value="root"/> 
     <property name="javax.persistence.jdbc.password" value="password"/> 
    </properties> 
</persistence-unit>

最后加入适当的驱动程序的POM文件。

<dependency> 
     <groupId>mysql</groupId> 
     <artifactId>mysql-connector-java</artifactId> 
     <version>5.1.18</version> 
    </dependency>
