cannot get proxied via CGLIB

改了一些代码，启动时有个INFO的提示，虽然说是INFO提示，但之前没见过；

2017-09-27 09:49:46,982 INFO (o.s.a.f.CglibAopProxy:) - Final method [private final void xxxx.xxx.AbstractDalService.baseValid(xxx.xxx.BasicDto)] cannot get proxied via CGLIB: Calls to this method will NOT be routed to the target instance and might lead to NPEs against uninitialized fields in the proxy instance.

因而打开CglibAopProxy类，看了一下缘由；

/**
	 * Checks for final methods on the given {@code Class}, as well as package-visible
	 * methods across ClassLoaders, and writes warnings to the log for each one found.
	 */
	private void doValidateClass(Class<?> proxySuperClass, ClassLoader proxyClassLoader, Set<Class<?>> ifcs) {
		if (proxySuperClass != Object.class) {
			Method[] methods = proxySuperClass.getDeclaredMethods();
			for (Method method : methods) {
				int mod = method.getModifiers();
				if (!Modifier.isStatic(mod)) {
					if (Modifier.isFinal(mod)) {
						if (implementsInterface(method, ifcs)) {
							logger.warn("Unable to proxy interface-implementing method [" + method + "] because " +
									"it is marked as final: Consider using interface-based JDK proxies instead!");
						}
						logger.info("Final method [" + method + "] cannot get proxied via CGLIB: " +
								"Calls to this method will NOT be routed to the target instance and " +
								"might lead to NPEs against uninitialized fields in the proxy instance.");
					}
					else if (!Modifier.isPublic(mod) && !Modifier.isProtected(mod) && !Modifier.isPrivate(mod) &&
							proxyClassLoader != null && proxySuperClass.getClassLoader() != proxyClassLoader) {
						logger.info("Method [" + method + "] is package-visible across different ClassLoaders " +
								"and cannot get proxied via CGLIB: Declare this method as public or protected " +
								"if you need to support invocations through the proxy.");
					}
				}
			}
			doValidateClass(proxySuperClass.getSuperclass(), proxyClassLoader, ifcs);
		}
	}

这就好改了嘛，将AbstractDalService.baseValid方法改为 static的就ok了，提示消失；

TODO

下来仔细分析一下，由其是AOP那么事；
