这是我写的测试加载上下文的测试

@RunWith(SpringRunner.class)
@SpringBootTest
public class LoadContextTest {

    @Test
    public void can_load_normal_context() {
        // Test vide, pour tester le chargement de context normal.
    }
}

这是我的 application.java 类

// Entry Point
@SpringBootApplication
@EnableZuulProxy
public class Application {
    public static void main(String[] args) {
        run(Application.class, args);
    }
}

执行测试类时出现此错误：

验证后，DelegatingApplicationListener 存在

启动应用程序时出现此错误

谁能帮帮我？

    【解决方案1】：

    您正在混合 Spring 框架的版本。除非您有非常充分的理由，否则不要这样做，否则您将在运行时遇到问题。

    请参阅此博客了解更多信息，了解为什么不这样做，

    https://spring.io/blog/2016/04/13/overriding-dependency-versions-with-spring-boot

    您应该通过 BOM 处理 Spring Boot 和 Spring Cloud 版本的导入。如果您添加或部分相应的启动器，则将管理所需的 Spring 框架的任何组件。此外，您可以只扩展 Spring Parent POM，而不使用 spring-boot-dependencies BOM。有关更多信息，请参阅文档https://docs.spring.io/spring-boot/docs/current/reference/html/using-boot-build-systems.html

           <scope>provided</scope>
        </dependency>

    此外，当打包为 WAR 时，您的主类应该类似于，

    @SpringBootApplication
public class SpringBootWebApplication extends SpringBootServletInitializer {
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
    return application.sources(SpringBootWebApplication.class);
}

public static void main(String[] args) throws Exception {
    SpringApplication.run(SpringBootWebApplication.class, args);
}

    在此处查看一个工作示例。 https://www.mkyong.com/spring-boot/spring-boot-deploy-war-file-to-tomcat/
