最近启动springboot项目的时候突然提示以下错误， 完全懵逼，之前的代码完全没有改动过， 过几天突然就报了这么一个错误

Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'appPackageDownloadCountController': Unsatisfied dependency expressed through field 'appPackageDownloadCountService'; nested exception is org.springframework.beans.factory.BeanNotOfRequiredTypeException: Bean named 'appPackageDownloadCountService' is expected to be of type 'com.seengene.ar.core.arcore.impl.AppPackageDownloadCountService' but was actually of type 'com.sun.proxy.$Proxy83'

Description:

The bean 'appPackageDownloadCountService' could not be injected as a 'com.seengene.ar.core.arcore.impl.AppPackageDownloadCountService' because it is a JDK dynamic proxy that implements:
    com.seengene.ar.core.arcore.dao.AppPackageDownloadCountDao


Action:

Consider injecting the bean as one of its interfaces or forcing the use of CGLib-based proxies by setting proxyTargetClass=true on @EnableAsync and/or @EnableCaching.


Process finished with exit code 1

原因：借鉴这里写链接内容
解决办法：在启动类中加上@EnableTransactionManagement(proxyTargetClass = true)就可以了

@SpringBootApplication(scanBasePackages = "com.seengene.ar")
@EnableTransactionManagement(proxyTargetClass = true)
public class RestfulApplication {

    public static void main(String[] args) {
        SpringApplication.run(RestfulApplication.class, args);
    }
}
