【问题描述】：

我正在尝试在我的 SpringBoot IntegrationTest 中使用 SpyBean。我的测试类如下

@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@RunWith(SpringRunner.class)
@EnableAutoConfiguration
public class MyTest {

    @SpyBean
    private MyService myService;

    @Test
    public void test() {
    }
}

我的 build.gradle 测试如下

testCompile group: 'org.mockito', name: 'mockito-all', version: '1.10.19'
testCompile group: 'org.powermock', name: 'powermock-api-mockito', version: '1.7.4'
testCompile group: 'org.powermock', name: 'powermock-module-junit4', version: '1.7.4'
testCompile "org.powermock:powermock-classloading-xstream:1.7.4"

当我尝试运行测试时，它会抛出以下异常

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'MyService' Initialization of bean failed; nested exception is java.lang.NoSuchMethodError: org.mockito.MockSettings.verificationStartedListeners([Lorg/mockito/listeners/VerificationStartedListener;)Lorg/mockito/MockSettings;

【问题讨论】：

你使用的是什么版本的 Spring Boot？
@Andy WilKinson ，我使用 2.1.0.RELEASE 弹簧靴
移除那些依赖，使用spring-boo-starter-test作为依赖。您正在使用旧版本的 Mockito 和相关框架。你真的需要power mock吗？
是的，我的测试中需要 powermock

标签： spring-boot mockito integration-testing powermockito

【解决方案1】：

要使用@MockBean 和@SpyBean，Spring Boot 2.1.0 需要 Mockito 2。您的依赖配置已将 Mockito 降级到 1.10。

我认为你有两个选择：

避免使用 Powermock，以便您可以使用 @MockBean 和 @SpyBean 所需的最新版本的 Mockito
避免使用 @MockBean 和 @SpyBean 来满足 Powermock 对旧版本 Mockito 的需求
