spring工程数据源使用的jndi如何junit做测试用例?报错

                    <pre>使用jndi数据源,需要依赖容器,所以不直接只用springtest做测试用例,使用junit的before方法绑定jndi.</pre> 

@Before
public void init() {
    System.out.println("ehcache缓存目录:" + System.getProperty("java.io.tmpdir"));

    try {
        ClassPathXmlApplicationContext app = new ClassPathXmlApplicationContext("classpath:spring/springtest/InitJndi.xml");
        DataSource ds = (DataSource) app.getBean("dataSource");
        SimpleNamingContextBuilder builder = new SimpleNamingContextBuilder();
        builder.bind("java:comp/env/jdbc/db1", ds);
        builder.activate();
        System.out.println("java:comp/env/jdbc/OracleDB init success...");

        ClassPathXmlApplicationContext appcontext = new ClassPathXmlApplicationContext("classpath:spring/spring.xml");

        //这里提取测试bean
        testCacheService = (TestCacheService) appcontext.getBean("testCacheService");
        sqlService = (SqlService) appcontext.getBean("sqlService");

        baseDao = (BaseDao) appcontext.getBean("baseDao");
        hibernateTemplate = (HibernateTemplate) appcontext.getBean("hibernateTemplate");

    } catch (Exception e) {
        e.printStackTrace();
    }
}

                        回复 <a class="referer" target="_blank">@tianxia007</a>  : 为何我还是有错
                    

                        此方法亲测可用
                    

                    <p>你好，请问能否把这两个配置文件贴出来呀</p>
