Mockitoをスパイしようとしたときに例外が発生する

Question

JunitテストでCustomerServiceを偵察したいと思います。私はその後、私のテスト全体の春のアプリケーションコンテキストを実行すると、これは私が私のテスト

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

に使用私の@profileですHow to Mock, Spy, and Fake Spring Beans

：私はAOPなしで私のテストに私のスパイを注入する方法については、この完璧な答えを見つけましたこの例外が発生してクラッシュする：

これを実行する方法を知っている人はいますか？

Answer 1

私は同じ問題がありました。私の問題は、@Transcationalによって注釈が付けられたメソッドによって引き起こされました。おそらくあなたがそれらを持っているときにあなたは真実のbeanではないプロキシオブジェクトを嘲笑/スパイしているでしょう。このBeanをそのままスパイすることはできますが、「Spring AOPでプロキシされたSpring Beanのスパイ」（How to Mock, Spy, and Fake Spring Beans）
