Spring Testing: How to enable auto-scan of beans
提问by user3594176
For example, now in each test class I have to do
例如，现在在每个测试类中我必须做
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(loader=AnnotationConfigContextLoader.class)
I want to get rid of
我想摆脱
@ContextConfiguration(loader=AnnotationConfigContextLoader.class)
and want Spring to scan all the beans in my project.
并希望 Spring 扫描我项目中的所有 bean。
How can I do that?
我怎样才能做到这一点？

If you have your spring configuration in an xml file you would use something like:
如果您在 xml 文件中有您的 spring 配置，您将使用以下内容：
@ContextConfiguration(locations="classpath:applicationContext.xml")
If you use Java Config then you would use
如果您使用 Java Config 那么您将使用
@ContextConfiguration(classes=Config.class)
I used generic names in the above samples, you'll of course need to adapt to your project's configuration.
我在上面的示例中使用了通用名称，您当然需要适应您的项目配置。
In both cases Spring's component scanning will need to be enabled for Spring to pickup the annotated classes.
在这两种情况下，都需要启用 Spring 的组件扫描，以便 Spring 拾取带注释的类。

You can do this:
你可以这样做：
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration
public class MyTest {
@Test
public void testSomething() {
}
@Configuration
@ComponentScan("basepackage")
public static class SpringConfig {
}
}
By default @ContextConfigurationwill look for static inner classes annotated with @Configuration, which is why this set up will just work.
默认情况下，@ContextConfiguration将查找用 注释的静态内部类@Configuration，这就是为什么这个设置会起作用的原因。
You can get rid of loader param altogether, that is not required
您可以完全摆脱 loader 参数，这不是必需的

You can also simply add @SpringBootTestif using Spring Boot.
@SpringBootTest如果使用 Spring Boot，您也可以简单地添加。
