@SpringBootTest在加载上下文时未创建内部bean

问题描述

我想了解为什么在尝试进行如下所示的测试时未创建内部bean:

I would like to learn why inner beans are not created while trying to test like below :

RunWith(SpringRunner.class)
@SpringBootTest(classes=MyTest.class)
public class MyTest {

     @SpyBean A a;



     @Test
     public  void  myTest() {
       assertTrue(a.some());
     }


    @Component
    class A {
      private B b;
      A(B dependency) {
        this.b = dependency;
      }
      boolean some() {
        return b.value();
      }
    }

    @Configuration
    class B {


      boolean value() { return true; }
    }

}

错误:No qualifying bean of type 'com.example.MyTest$B' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations:

尽管使用@Configuration注释内部类，但在测试方法时并未创建Bean.

Despite annotating the inner class with @Configuration it is not creating the bean while testing the method.

请注意，当我在@SpringBootTest(classes=MyTest.class,MyTest.B.class,MyTest.A.class})

推荐答案

将@ContextConfiguration(classes = MyTest.B.class)添加到MyTest类中.但将配置放入测试类中并不是最好的主意.最好创建单独的配置类MyTestConfig，该类创建所有需要测试的bean，并由@ContextConfiguration(classes = MyTestConfig.class)在测试类中使用它.

Add @ContextConfiguration(classes = MyTest.B.class) to the MyTest class.
Butputting configuration into a test class isn't the best idea. It's better to create separate configuration class MyTestConfig that create all need beans for test and use it in the test class by @ContextConfiguration(classes = MyTestConfig.class).
