试图与Mockito进行间谍时有例外

我想在Junit测试中窥探我的CustomerService。我找到了关于如何在没有AOP的情况下将我的间谍注入我的测试的完美答案：How to Mock, Spy, and Fake Spring Beans

这是我用于测试的@profile 

@Bean
@Primary
public CustomerService getCustomerService(CustomerService customerService) {
    return Mockito.spy(customerService);
}

当我运行测试时，整个spring应用程序上下文崩溃时出现以下异常：

Caught exception while allowing TestExecutionListener [org.springframework.test.context.web.ServletTestExecutionListener@5579bb86] to prepare test instance [CustomerControllerTest@451f3f66]

任何人都知道怎么做这个运行？

答案 0 :(得分：0)

我有同样的问题。我的问题是由@Transcational注释的方法引起的。可能当你拥有它们时，你正在嘲笑/监视代理对象而不是真正的bean。您可以按原样间谍这个bean，而是使用How to Mock, Spy, and Fake Spring Beans

中的“Spring Spring AOP上的Spy on Spring Bean”中描述的方法
