错误：Attempted to load applicationConfig: [classpath:/application.yml] but snakeyaml was not found on the classpath

MyEclipse导入工程，报错如下：

这是因为YML文件解析需要引入的snakeyaml包未找到造成的，解决方式，在pom.xml文件<dependencies></dependencies>元素内添加如下语句：

    <dependency>
            <groupId>org.yaml</groupId>
            <artifactId>snakeyaml</artifactId>
            <version>1.23</version>
        </dependency>
        
        <dependency>

            <artifactId>testng</artifactId>
