我正在尝试运行TestNG + Spring + JPA + Hibernate'Hello World'测试。执行结果为NullPointerException，tiles configurer bean失败。

我的applicationContext.xml，只显示了瓷砖配置bean def：
<bean id="tilesConfigurer"
class="org.springframework.web.servlet.view.tiles2.TilesConfigurer">
<property name="definitions">
<list>
<value>/WEB-INF/tiles/tiles.xml</value>
</list>
</property>
</bean>

@Inject

@Test(groups = { "fast" })
@Rollback(value = false)

Faculty f = new Faculty();
f.setFirstName("John");
f.setLastName("Frost");
f.setCpsoNumber("23198");
f = facultyDao.makePersistent(f);

}
@Test(groups = { "fast" })

}
任何指针都将非常感激。
答案 0 :(得分：4)
您的测试加载了特定于Web应用程序的配置文件，但您的测试环境未提供所需的文件：
您需要将Web应用程序特定的配置与不适用于Web应用程序上下文的配置分开。
然后使用没有Web应用程序的测试。
对于您的意思是：删除测试配置的Tiles配置。因为在测试中/WEB-INF/tiles/tiles.xml文件不可用。
