Spring Integration Testing: Could not detect default resource locations
提问by lanoxx
I am running integration tests for my Spring Boot application with Maven's Failsafe plugin. When I create a simple test such as this one:
我正在使用 Maven 的 Failsafe 插件为我的 Spring Boot 应用程序运行集成测试。当我创建一个像这样的简单测试时：
@RunWith (SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(App.class)
public class MyTestIT {
@Test
public void test() {
assertTrue (true);
}
}
And then run mvn verifyI see the following log entries just before the Spring application starts (e.g. even before the Spring Boot banner):
然后运行mvn verify我在 Spring 应用程序启动之前（例如甚至在 Spring Boot 横幅之前）看到以下日志条目：
Running org.....MyTestIT
2016-04-14 13:25:01.166 INFO ???? --- [ main]
or.sp.te.co.su.AbstractContextLoader :
Could not detect default resource locations for test class

{-context.xml, Context.groovy}.
2016-04-14 13:25:01.175 INFO ???? --- [ main]

2016-04-14 13:25:01.185 INFO ???? --- [ main]

Followed by the Spring Boot banner. The tests then run through without any error. While these messages are printed with an INFO log level and the tests run fine, I guess everything is fine, but I still find these messages irritating.So is there something wrong with my configuration? Should I worry about these messages?
其次是 Spring Boot 横幅。然后测试通过而没有任何错误。虽然这些消息是用 INFO 日志级别打印的，并且测试运行良好，但我想一切都很好，但我仍然觉得这些消息很烦人。那么我的配置有问题吗？我应该担心这些消息吗？
Even if there was nothing wrong, I would still like to understand whats happending there and what the messages mean.
即使没有任何问题，我仍然想了解那里发生了什么以及消息的含义。
My maven-failsafe-pluginis just using the default configuration and my App.javais just a simple class annotated with @SpringBootApplication.
我maven-failsafe-plugin只是使用默认配置，而我App.java只是一个用@SpringBootApplication.
UPDATE 1:
更新1：
Here is the configuration of my test plugins:
这是我的测试插件的配置：
<plugin>
<artifactId>maven-surefire-plugin</artifactId>
<configuration>
<!-- Ignore any tests that are marked by the @IntegrationTest annotation of Spring Boot -->
<excludedGroups>org.springframework.boot.test.IntegrationTest</excludedGroups>
</configuration>
</plugin>
<plugin>
<artifactId>maven-failsafe-plugin</artifactId>
<version>2.19.1</version>
<executions>
<execution>
<id>integration-test</id>
<goals>
<goal>integration-test</goal>
</goals>
</execution>
</executions>
</plugin>
I also have a spring-boot-starter-testdependency configured and I am using spring-boot-devtools. Besides that everything else is not test related.
我还spring-boot-starter-test配置了一个依赖项，我正在使用spring-boot-devtools. 除此之外，其他一切都与测试无关。
The project it self is pretty standard, using hibernate and mysql and web-mvc for rest endpoints. I have two configuration classes for spring security on the class pass.
它本身的项目非常标准，使用 hibernate 和 mysql 以及 web-mvc 作为休息端点。我在班级通行证上有两个用于 spring 安全性的配置类。
In the main/resourcesfolder I have an application.propertiesfile and a log4j2.xml. There is no test/resourcesfolder, but when I just copy the main/resources folder to test/resourcesthe above log messages still appear.
在main/resources文件夹中，我有一个application.properties文件和一个 log4j2.xml。没有test/resources文件夹，但是当我只是将 main/resources 文件夹复制到test/resources上述日志消息时仍然出现。
UPDATE 2:I just created a small sample application trying to recreate the issue, and it seems the mentioned log-output starts to appear as soon as I put a log4j2.xmlfile into a resources folder. I tried putting it in src/mainor src/testor both with identical effects.
更新 2：我刚刚创建了一个小的示例应用程序来尝试重新创建该问题，似乎一旦我将log4j2.xml文件放入资源文件夹中，提到的日志输出就会开始出现。我试图把它src/main或src/test或两者具有相同的效果。

This is the default behaviour when running Spring integration tests.
这是运行 Spring 集成测试时的默认行为。
From the reference documentation
从参考文档
If you omit both the locations and value attributes from the @ContextConfiguration annotation, the TestContext framework will attempt to detect a default XML resource location. Specifically, GenericXmlContextLoader and GenericXmlWebContextLoader detect a default location based on the name of the test class. If your class is named com.example.MyTest, GenericXmlContextLoader loads your application context from "classpath:com/example/MyTest-context.xml".
如果您从 @ContextConfiguration 注释中省略了 location 和 value 属性，TestContext 框架将尝试检测默认的 XML 资源位置。具体来说，GenericXmlContextLoader 和 GenericXmlWebContextLoader 根据测试类的名称检测默认位置。如果您的类名为 com.example.MyTest，GenericXmlContextLoader 将从“classpath:com/example/MyTest-context.xml”加载您的应用程序上下文。
So, it's not related whatsoever to Maven, log4j or the positioning/assistance of resource folder.
因此，它与 Maven、log4j 或资源文件夹的定位/帮助无关。
Should I worry about these messages?
我应该担心这些消息吗？
Not at all, apparently.
完全没有，显然。
but I still find these messages irritating
但我仍然觉得这些信息很烦人
Don't know if and how to turn off that check (Course you can eliminate it by changing the log level of AbstractContextLoaderto WARN).
不知道是否以及如何关闭该检查（当然您可以通过将日志级别更改为AbstractContextLoaderto来消除它WARN）。

You can annotate you test class with more specific configs for loader and use Java Config
您可以使用更具体的加载器配置来注释测试类并使用 Java Config
Something like:
就像是：
@ContextConfiguration(loader=AnnotationConfigContextLoader.class, classes = ScalaTestConfig.class)
Where ScalaTestConfig class is annotated with:
其中 ScalaTestConfig 类注释为：
@Configuration
@ComponentScan(basePackages = {"***", "***"})
Based on Kulasangar's link.
