Java BeanCreationNotAllowedException在SpringBoot项目中的junit测试之后

我有一个Spring Boot项目。
它可以成功启动。
我添加了这样一个测试：

@WebAppConfiguration
@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest(classes = SopStart.class, webEnvironment = SpringBootTest.WebEnvironment.MOCK)
public class Test{
    @Test
    public void test(){
        System.out.println("success!");
    }
}

“成功！”可以成功打印。但最后我得到了一个例外：

它正在拾取默认的

应用程序

类。尝试为测试类定义您的WIN配置，该测试类不包括某些自动配置的bean，包括

EurekaClientAutoConfiguration

，这是您的测试抱怨的主要原因

您可能也不需要

@WebAppConfiguration

。您甚至可能会得到一个

java.lang.IllegalStateException

举个例子,

@ActiveProfiles("test")
//@WebAppConfiguration
@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest(classes = TestExample.class, webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@ContextConfiguration(classes = {Test.CustomConfiguration.class})
public class Test {

    @Configuration
    @EnableConfigurationProperties
    @EnableAutoConfiguration(exclude = {HibernateJpaAutoConfiguration.class,
            JpaRepositoriesAutoConfiguration.class,
            DataSourceAutoConfiguration.class,  
            EurekaClientAutoConfiguration.class})
    static class CustomConfiguration {

    }

    @Test
    public void test() {
        System.out.println("success!");
    }
}
