在NetBeans中使用带有javen测试和Maven项目的JDBC查找检查错误

Question

我正在尝试为使用jdbc资源的文件创建测试。 常规测试在整个项目中都可以正常工作，但当我尝试使用实体管理器进行测试时除外。 我想这里缺少一些简单的东西，希望能对您有所帮助。

这是错误。

这是我已采取的一些故障排除步骤：

• 将玻璃鱼演员添加到行家POM
• 我将持久性文件放置在/ main / resources和/ test / resources文件夹中。
• 我尝试将属性添加到DonationsFacadeTest文件的@BeforeClass方法中的上下文对象中，以及大约一百万与以下类似的其他配置。

环境信息：

• 使用Netbeans 7.0.1
• Maven项目
• 玻璃鱼3.1

DonationsFacade.java-此类使用外观模式提供对JPA实体的间接访问。

@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-只是尝试编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();
}
}

再次感谢您的帮助，非常感谢。

Answer 1

在这里找出答案。 我基本上将一个entitymanager注入到该类中。 希望这对尝试做同样事情的人有所帮助。

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);

}
}

适当修改了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，将适当的驱动程序添加到POM文件中。

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