Java Spring如何模拟实现相同接口的bean

Question

我有一个bean，它是按照创建的

@Profile({"test", "dev", "int"})
@Bean
public CustomerEmailSenderImpl customerEmailSenderImpl(){
return new CustomerEmailSenderImpl ();
}

在一个测试课上，我嘲笑这个班如下：

@ActiveProfiles(profiles = {"test"})
.....
@MockBean
private CustomerEmailSenderImpl customerEmailSenderImpl;

现在。我必须创建第二个电子邮件类，该类必须在使用profile"时专门使用；测试"；。因此，我创建了一个接口(CustomerEmailSender(，这两个类都实现了该接口。bean的创建过程如下。

@Profile({"dev", "int"})
@Bean(name = "customerEmailSender")
public CustomerEmailSender customerEmailSenderImpl1(){
return new CustomerEmailSenderImpl1 ();
}
@Profile({"test"})
@Bean(name = "customerEmailSender")
public CustomerEmailSender customerEmailSenderImpl2(){
return new CustomerEmailSenderImpl2 ();
}

Mock我改了一个跟随

@ActiveProfiles(profiles = {"test"})
...
@MockBean
private CustomerEmailSender customerEmailSender;

应用程序启动时没有出现错误。但是该测试并没有模拟bean CustomerEmailSenderImpl2。bean总是被实例化，并且实际的代码被执行。即使在测试类中从Interface更改为类名也无济于事：

@MockBean
private CustomerEmailSenderImpl2 customerEmailSenderImpl2;

需要什么来模拟bean CustomerEmailSenderImpl2？

解决方案是使用@Qualifier，然后在测试类中使用限定符名称作为变量名称。

@Profile({"test"})
@Bean(name = "customerEmailSender")
@Qualifier(value="customerEmailSenderImpl2")
public CustomerEmailSender customerEmailSenderImpl2(){
return new CustomerEmailSenderImpl2 ();
}

@MockBean
private CustomerEmailSender customerEmailSenderImpl2;
