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

MyEclipse導入工程，報錯如下：

這是因為YML文件解析需要引入的snakeyaml包未找到造成的，解決方式，在pom.xml文件<dependencies></dependencies>元素內添加如下語句：

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