java-如何在不继承“ spring-boot-starter-parent”模块的情况下测试我的Spring-Boot应用程序？

我有一个基于Spring Boot构建的非常简单的应用程序.但是由于内部公司的政治原因,它没有继承spring-boot-starter-parent.

>如何使我的测试与注解SpringApplicationConfiguration一起使用？
>更笼统地说,是否有一个“清单”可以使Spring Boot在不继承spring-boot-starter-parent的情况下工作(编译,测试,打包…)？

我的测试课：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(loader = SpringApplicationContextLoader.class)
@SpringApplicationConfiguration(classes = MyModule.class)
public class MyModuleTest { /* ... */ }

如果我使用spring boot parent来运行应用程序,那么就可以了(但是不能).

如果我在没有父母的情况下运行测试,则会出现此错误：

谢谢你的帮助

解决方法:

实际上,此错误不是我所想的那样是由于缺少插件引起的,而是由于春季版本(3.x)不好,而不是4.0.6.RELEASE(今天)引起的.

更改版本并将其添加到pom.xml中,此配置对我有用：

<project>
    <!-- ... -->
    <build>
        <plugins>
            <plugin>
                <artifactId>maven-war-plugin</artifactId>
                <configuration>
                    <failOnMissingWebXml>false</failOnMissingWebXml>
                </configuration>
            </plugin>
        </plugins>
    </build>

    <dependencyManagement>
        <dependencies>
            <dependency>
                <!-- Import dependency management from Spring Boot -->
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-dependencies</artifactId>
                <version>1.1.4.RELEASE</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>
</project>
