我想运行一个Maven安装，但是我得到了一个“org.springframework.beans.factory.BeanCreationException”异常。以Maven目标启动可以正常工作。不幸的是，我找不到为什么示例没有被填充的错误。
这个项目是一个 Boot 应用程序，它有一个Jswing用户界面，可以调用几个api，并包含自己的rest控制器。
主类：

我通过向pom.xml添加以下插件（包括配置）解决了这个问题。

<plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <version>2.19.1</version>
            <configuration>
                <testFailureIgnore>true</testFailureIgnore>
            </configuration>
        </plugin>

在那之后，我再也没有遇到任何例外。
