試圖與Mockito進行間諜時有例外

Question

我想在Junit測試中監視我的CustomerService。 我找到了關於如何在沒有AOP的情況下將我的間諜注入我的測試的完美答案： 如何模擬，間諜和假春豆

這是我用於測試的@profile

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

然后當我運行我的測試時，整個spring應用程序上下文崩潰時出現以下異常：

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

任何人都知道如何運行？

Answer 1

我遇到過同樣的問題。 我的問題是由@Transcational注釋的方法引起的。 可能當你擁有它們時，你正在嘲笑/監視代理對象而不是真正的bean。 您可以原樣監視這個bean，而不是使用如何模擬，間諜和假春豆在“Spring Spring AOP上的Spy on Spring Bean”中描述的方法
