Question

以下是我使用jpa的junit测试用例

package com.msat.srt.dao;

import static org.junit.Assert.*;

import java.util.List;



import javax.persistence.EntityManager;  
import javax.persistence.EntityManagerFactory;  
import javax.persistence.Persistence;  
import javax.persistence.Query;

import org.apache.log4j.BasicConfigurator;  
import org.apache.log4j.Level;  
import org.apache.log4j.Logger;  
import org.junit.Before;  
import org.junit.BeforeClass;  
import org.junit.Ignore;  
import org.junit.Test;  


import com.msat.srt.vo.MarvalUpdateVO;

public class MarvalUpdateEJBTest {

      private static final String PERSISTENCE_UNIT_NAME = "SRTEJB";
      private static EntityManagerFactory emf;
      private EntityManager em;

    @BeforeClass
        public static void initializeLogging() {
          BasicConfigurator.configure();
          Logger.getLogger("org").setLevel(Level.ERROR);
        }

    @Before
      public void setUp() throws Exception {
         emf = Persistence.createEntityManagerFactory(PERSISTENCE_UNIT_NAME);
         em = emf.createEntityManager();

     }
    @Test
    public void testGetAllTicketTypes() {

        Query qry = em.createQuery("select tb from TblSrtttypemaster tb");
        assertTrue(qry.getResultList().size() == 4);
          }

    }

我收到以下错误消息..我不知道如何纠正它。我是否需要在上面的测试类中再次包含db连接的属性??

我正在使用JPA，这是我的persistence.xml

<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.0" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">
    <persistence-unit name="SRTEJB" transaction-type="JTA">
    <provider>org.hibernate.ejb.HibernatePersistence</provider>
    <jta-data-source>jdbc/srt</jta-data-source>

    <properties>
        <property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect"/>

这似乎是使用其中一个依赖项的问题

<dependency>  
   <groupId>javax</groupId>  
   <artifactId>javaee-api</artifactId>  
   <version>6.0</version>  
</dependency> 

OR

<dependency>  
   <groupId>javax</groupId>  
   <artifactId>javaee-web-api</artifactId>  
   <version>6.0</version>  
</dependency>

作为州here：

此依赖项为您提供Java EE API，而不是实现。虽然此依赖项适用于编译，但它不能用于执行代码（包括测试）。

mkyong的一个解决方案：

好的做法是始终从http://java.sun.com/javaee/获取原始完整版本的javaee.jar文件。只需下载并安装J2EE SDK，就可以在“\ J2EE_SDK_FOLDER \ lib”文件夹中找到javaee.jar。将它包含在您的本地Maven存储库或poject类路径中将消除上述错误消息。

community.jboss提供的另一种解决方案：

在两种情况下实际适用的另一种解决方案是使用[服务器供应商]提供的Java EE规范工件，例如

<dependency>
    <groupId>org.glassfish</groupId>
    <artifactId>javaee-api</artifactId>
    <version>3.1.1</version>
</dependency>

你可以search related issues。虽然＆＃34;缺席代码＆＃34;可能不一样，你会发现问题主要是由于＆＃34;空＆＃34; javaee-api jar
