封装AopContext.currentProxy()对象失败

最近在项目中封装工具类SpringUtils，其中有一个静态方法是获取aop代理对象，但是使用的时候确产生了如下的异常：

java.lang.IllegalStateException: Cannot find current proxy: Set 'exposeProxy' property on Advised to 'true' to make it available, and ensure that AopContext.currentProxy() is invoked in the same thread as the AOP invocation context.
	at org.springframework.aop.framework.AopContext.currentProxy(AopContext.java:69)
	at com.jlkj.jwxt.common.core.util.SpringUtils.getAopProxy(SpringUtils.java:98)
	at com.jlkj.jwxt.admin.service.impl.SysRoleServiceImpl.selectRoleAll(SysRoleServiceImpl.java:99)
	at com.jlkj.jwxt.admin.service.impl.SysRoleServiceImpl$$FastClassBySpringCGLIB$$b8930bc3.invoke()
	at org.springframework.cglib.proxy.MethodProxy.invoke(MethodProxy.java:218)

@Component
public final class SpringUtils implements BeanFactoryPostProcessor {


    @SuppressWarnings("unchecked")
    public static  T getAopProxy(T invoker) {
        return (T) AopContext.currentProxy();
    }
}
  

@EnableFeignClients
@SpringBootApplication
@EnableDiscoveryClient
@EnableAsync
@MapperScan("com.lfc.admin.mapper.**")
public class AdminSystemApplication {
    public static void main(String[] args) {
        SpringApplication.run(AdminSystemApplication.class, args);
    }
}

通过报错信息可以看出缺少了属性 exposeProxy ，那么查找AOP相关的文档，或者开启的方式是在启动类上增加相应注解即可：
@EnableAspectJAutoProxy(exposeProxy = true, proxyTargetClass = true)

@EnableFeignClients
@SpringBootApplication
@EnableDiscoveryClient
@EnableAsync
@MapperScan("com.lfc.admin.mapper.**")
@EnableAspectJAutoProxy(exposeProxy = true, proxyTargetClass = true)
public class AdminSystemApplication {
    public static void main(String[] args) {
        SpringApplication.run(AdminSystemApplication.class, args);
    }
}
