Could not load TestContextBootstrapper - Spring Unit testing
提问by Tariq
I have to execute Unit test on one of my Dao classes using Spring. Here is my unit test:
我必须使用 Spring 对我的 Dao 类之一执行单元测试。这是我的单元测试：
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"classpath:app-config.xml"})
@ActiveProfiles("local")
public class HouseDaoTest {
@Autowired
HouseDataDao houseDataDao;
@Test
public void saveTest(){
HouseData data = new HouseData();
Address add = new Address();
// Truncating for sake of simplicity
houseDataDao.save(data);
}
}
And My bean configuration files:
和我的 bean 配置文件：
app-config.xml:
应用程序配置文件：
<?xml version="1.0" encoding="UTF-8"?>

</beans>
Where BeanConfiguration-production.xml is same as above except for <beans profile="production" ...in it.
其中 BeanConfiguration-production.xml 与上面相同，除了<beans profile="production" ...在里面。
When I simply execute a maven test doing mvn testit fails throwing the following exception:

... 25 more
It looks like I am missing a dependency or something, because the stacktrace contains Caused by: java.lang.NoSuchMethodError: org.springframework.beans.BeanUtils.instantiateClass.
看起来我缺少依赖项或其他东西，因为堆栈跟踪包含Caused by: java.lang.NoSuchMethodError: org.springframework.beans.BeanUtils.instantiateClass.

It is probably a version conflict since you are using a old version of base spring (2.5.6) with very new one (4.1.4.RELEASE) for your test en context includes
这可能是版本冲突，因为您使用的是旧版本的基础 spring (2.5.6) 和非常新的 (4.1.4.RELEASE) 用于您的测试环境包括
回答by lmyers
In my case it was a version conflict caused by activemq-all. That dependency (5.12.2 in my case) includes an incompatible version of spring (I just upgraded to spring 4.3.4). So, save yourself a few hours of debugging and check not only the Dependency Hierarchy in your favorite IDE, but also look inside those jar files to see if any are embedding org.springframework packages.
就我而言，这是由 activemq-all 引起的版本冲突。该依赖项（在我的情况下为 5.12.2）包括不兼容的 spring 版本（我刚刚升级到 spring 4.3.4）。因此，为自己节省几个小时的调试时间，不仅要检查您最喜欢的 IDE 中的依赖关系层次结构，还要查看这些 jar 文件以查看是否有任何嵌入 org.springframework 包。
