@SpringBootTest在加载上下文时未创建内部bean
问题说明
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})
正确答案
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.
But putting 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).
