我想编写一个不属于Spring bean的方法的建议(Spring Boot 1.4.4.RELEASE):
@Component
@Aspect
...
@Around("execution(public * com.netflix.appinfo.InstanceInfo.getId())")
我添加了aspectjrt和spring-instrument(??)依赖项
我添加了@EnableAspectJAutoProxy和@EnableLoadTimeWeaving(aspectjWeaving = AspectJWeaving.ENABLED)注释
我添加了VM参数:
-javaagent:d:\.m2\repository\org\springframework\spring-instrument\4.3.6.RELEASE\spring-instrument-4.3.6.RELEASE.jar
-javaagent:d:\.m2\repository\org\aspectj\aspectjweaver\1.8.9\aspectjweaver-1.8.9.jar
处理bean(postconstruct日志),但没有截获执行。 有没有人对我可能错过的东西有所了解? Thx提前

好的,对于那些感兴趣的人来说,这是一个技巧,单例模式处理对LTW和Spring的单例的访问,因此在被LTW编织后可以注入Spring依赖项:
@Configuration
@Aspect
public class MyAspect {
@Value("${mycompany.property}")
private String myKey;
@Around("execution(public * com.mycompany.NotASpringean.getProperty())")
public String weave(ProceedingJoinPoint jp) throws Throwable {
String value = (String) jp.proceed();
// transform the value thx to injected myKey value
return value;
}
@Bean("post-construct-aspect")
public MyAspect init() {
return MyAspect.aspectOf(); // get existing instance via factory method
}
private static MyAspect instance = new MyAspect();
/** Singleton pattern used by LTW then Spring */
public static MyAspect aspectOf() {
return instance;
}
}

尝试使用@Pointcut
注释,如下所示:
@Pointcut("execution(public * com.netflix.appinfo.InstanceInfo.getId())")
public void pointcut() {}
@Around("pointcut()")
public Object whatever(ProceedingJoinPoint joinPoint) throws {...}
