【问题描述】:
我正在尝试将 Spring AOP 与 Spring MVC 控制器一起使用。 我有 3 个方面,并希望按特定顺序进行。为此,我使用了 Ordered 接口并实现了 getOrder 方法:
@Aspect
@Component
public class LoggingAspect implements Ordered{
public int getOrder() {
System.out.println("Abra");
return 1;
}
建议类:
@Component
@Controller
public class HomeController {
切入点:
@Aspect
public class SystemArchitecture {
@Pointcut("execution (* com.jajah.StorageManager.HomeController.*(..))")
public void inHomeController(){}
@Pointcut("execution (* com.jajah.StorageManager.HomeController.*(..))")
public void loggable(){}
@Pointcut("execution (* com.jajah.StorageManager.HomeController.*(..))")
public void authenticated(){}
}
配置:

getOrder 不能解决问题。 我将不胜感激任何实用的建议,或者如果您没有确切的答案,我将不胜感激有关 Spring 代理和编织机制的任何理论知识。
我会根据需要发布任何所需的代码/配置。 感谢阅读。
更新: 1. 我尝试@Order(1) 得到相同的结果。 2.我尝试将方面移动到同一个包中,它改变了它们的顺序,但我仍然无法控制它。
