How to test afterPropertiesSet method in my spring application?
提问by AKIWEB
I am working on writing some junit test for my spring application. Below is my application which implements InitializingBean interface,
我正在为我的 spring 应用程序编写一些 junit 测试。下面是我实现 InitializingBean 接口的应用程序，
public class InitializeFramework implements InitializingBean {
@Override
public void afterPropertiesSet() throws Exception {
try {
} catch (Exception e) {
}
}
}
Now I want to call afterPropertiesSetmethod from my junit test but somehow, I am not able to understand what is the right way to do this? I thought, I can use reflection to call this method but I don't think, it's a right way to do that?
现在我想afterPropertiesSet从我的 junit 测试中调用方法，但不知何故，我无法理解这样做的正确方法是什么？我想，我可以使用反射来调用这个方法，但我不认为，这是一个正确的方法吗？
Can anyone provide me a simple example for this on how to write a simple junit test that will test afterPropertiesSetmethod in InitializeFrameworkclass?
任何人都可以为我提供一个简单的例子，说明如何编写一个简单的 junit 测试来测试类中的afterPropertiesSet方法InitializeFramework？

InitializingBean#afterProperties()without any ApplicationContextis just another method to implement and call manually.
InitializingBean#afterProperties()没有任何ApplicationContext只是另一种手动实现和调用的方法。
@Test
public void afterPropertiesSet() {
InitializeFramework framework = new InitializeFramework();
framework.afterPropertiesSet();
// the internals depend on the implementation
}
Spring's BeanFactoryimplementations will detect instances in the context that are of type InitializingBeanand, after all the properties of the object have been set, call the afterPropertiesSet()method.
Spring 的BeanFactory实现将检测上下文中类型的实例，InitializingBean并在设置对象的所有属性后调用该afterPropertiesSet()方法。
You can test that too by having your InitializeFrameworkbean be constructed by an ApplicationContextimplementation.
您也可以通过让您的InitializeFrameworkbean 由ApplicationContext实现构造来测试它。
Say you had
说你有
@Configuration
public class MyConfiguration {
@Bean
public InitializeFramework initializeFramework() {
return new InitializeFramework();
}
}
And somewhere in a test (not really junit worthy though, more of an integration test)
在测试中的某个地方（虽然不是真正的 junit，但更多的是集成测试）
AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext(MyConfiguration.class);
When the context loads you will notice that the afterPropertiesSet()method of the InitializeFrameworkbean is called.
当上下文加载时，您会注意到调用afterPropertiesSet()了InitializeFrameworkbean的方法。
