我正在尝试在已使用MySQL驱动程序运行Restful服务的项目中构建基于MongoDB的restful服务。以下是我得到的例外情况。

更新：
当我将我的依赖关系更新到下面时它起作用了。但请好好解释一下原因。
依赖项{
compile 'org.codehaus.groovy:groovy-all:2.3.7'
//Spring Boot dependency
compile "org.springframework.boot:spring-boot-starter-web"
compile("org.springframework.boot:spring-boot-starter-data-mongodb")
compile('mysql:mysql-connector-java:5.1.6')
