用于测试 EJB 的 JUnit 和 OpenEJB 中的问题

编程问答 2022-05-01

问题描述

我是单元测试的初学者。我在 Eclipse Kepler 和 Maven 以及 jboss 5.0 和 Java 8 中构建了一个 EJB 应用程序。 我想用 JUnit 和 openEJB 测试 EJB，但是当我想配置时，我遇到了问题。我正在努力解决这个问题

这是我的 oracle-ds.xml：

<!DOCTYPE xml>
<datasources>
    <local-tx-datasource>
        <jndi-name>OracleDS</jndi-name>
        <connection-url>url</connection-url>
        <driver-class>oracle.jdbc.driver.OracleDriver</driver-class>
        <user-name>user</user-name>
        <password>pass</password>

            <type-mapping>Oracle9i</type-mapping>
        </Metadata>
    </local-tx-datasource>
</datasources>

这里是persistence.xml文件：

<persistence version="1.0"
    xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">
    <persistence-unit name="EjbComponentPU" transaction-type="JTA">
    <provider>org.hibernate.ejb.HibernatePersistence</provider>
        <jta-data-source>java:/OracleDS</jta-data-source>
        <class>ir.simorgh.entity.Book</class>
        <exclude-unlisted-classes>false</exclude-unlisted-classes>
        <properties>
            <property name="hibernate.hbm2ddl.auto" value="update" />
            <property name="hibernate.dialect" value="org.hibernate.dialect.Oracle9iDialect" />
        </properties>
    </persistence-unit>
</persistence>

这是我的测试：

package ir.simorgh.stateless;

import ir.simorgh.stateless.LibraryPersistentBean;
import java.util.Properties;
import javax.ejb.EJB;
import javax.ejb.embeddable.EJBContainer;
import javax.naming.Context;

import junit.framework.TestCase;

public class LibraryPersistentBeanTest extends TestCase {
    @EJB
    private LibraryPersistentBean libraryPersistentBean;

    private Context initialContext;

    protected void setUp() throws Exception {
        final Properties props = new Properties();
        props.put("OracleDS","new://Resource?type=DataSource");
        props.put("OracleDS.jdbcDriver ","org.hsqldb.jdbcDriver");
        props.put("OracleDS.jdbcUrl ","jdbc:hsqldb:mem:moviedb");
        props.put("EjbComponentPU.hibernate.dialect ","org.hibernate.dialect.HsqlDialect");
        initialContext = EJBContainer.createEJBContainer(props).getContext();
    }

    public void test() throws Exception {
        Object obj = initialContext.lookup("LibraryPersistentBeanRemote");
        assertNotNull(obj);
        assertTrue(obj instanceof LibraryPersistentBeanRemote);
    }
}

提前致谢。
