问题描述
我有此代码，
@RunWith(SpringJUnit4ClassRunner.class)
public class JunitDemo {
@Test
public void testAssertArrayEquals() {
byte[] expected = "trial".getBytes();
byte[] actual = "trial".getBytes();
Assert.assertArrayEquals("fail", expected, actual);
}
}
并运行测试，有错误
然后，我找到与SO相同的Q，解决方案是
then, i find a same Q with SO,the solution is
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration
public class JunitDemo {
@Resource
private ApplicationContext ApplicationContext;
@Test
public void testAssertArrayEquals() {
byte[] expected = "trial".getBytes();
byte[] actual = "trial".getBytes();
Assert.assertArrayEquals("fail", expected, actual);
}
}
事实上，对于本pojo，我不需要xml配置.我会收到其他错误
in fact，for this pojo, i do'nt need the xml config.and i will get other error
如何正确运行我的程序?

推荐答案
来自 @ ContextConfiguration docs:
注释本身具有属性loader，文档说:
Annotation itself has property loader and doc says:
在运行时选择的默认具体实现.
The default concrete implementation chosen at runtime.
因此您可以指定上下文.要导航到直接配置，请对XML使用locations，对带注释的类config使用classes.
So you can specify context loader directly with loader property. To navigate to direct configuration use locations for xml and classes for annotated class config.
在您看来是弹簧选择GenericXmlContextLoader进行上下文加载的情况下，您无需指定位置，因此ApplicationConext将从"classpath:/com/example/< _test_class_name >-context.xml"
In you case looks like spring chosen GenericXmlContextLoader for context loading, you don't specify location so ApplicationConext will be loaded from "classpath:/com/example/<your_test_class_name>-context.xml"
这是关于它的好文章.
这篇关于@RunWith(SpringJUnit4ClassRunner.class)无法使用NULL'contextLoader'加载ApplicationContext的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
