使用tomcat服务器启动项目的时候,报了error creating bean with name 'citycontroller': injection of autowired dependencies failed;
nested exception is org.springframework.beans.factory.beancreationexception: could not autowire field: private com.formstest.service.icityservice com.formstest.controller.citycontroller.icityservice;
nested exception is org.springframework.beans.factory.nosuchbeandefinitionexception: no qualifying bean of type [com.formstest.service.icityservice] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. dependency annotations: {@org.springframework.beans.factory.annotation.autowired(required=true)}
这样的问题之前也出现过,主要是因为在编写service实现类的时候忘记添加:implements 进行接口实现,从而导致无法创建bean:citycontroller
