Answer 1

问题在于Unsatisfied dependency expressed through constructor parameter 0: Could not convert argument value of type [java.lang.String] to required type [java.lang.Class]:，意思是在使用ChinaOlyAuthMapper的参数是[java.lang.Class]类型，但是绑定参数传的类型是[java.lang.String]，所以无法创建ChinaOlyAuthMapper的bean，可以详细看下ChinaOlyAuthMapper绑定参数是否有误
