package org.springframework.aop.framework;

import org.springframework.core.NamedThreadLocal;

public abstract class AopContext {
    private static final ThreadLocal<Object> currentProxy = new NamedThreadLocal("Current AOP proxy");

    public AopContext() {
    }

    public static Object currentProxy() throws IllegalStateException {
        Object proxy = currentProxy.get();
        if (proxy == null) {
            throw new IllegalStateException("Cannot find current proxy: Set 'exposeProxy' property on Advised to 'true' to make it available.");
        } else {
            return proxy;
        }
    }

    static Object setCurrentProxy(Object proxy) {
        Object old = currentProxy.get();
        if (proxy != null) {
            currentProxy.set(proxy);
        } else {
            currentProxy.remove();
        }

        return old;
    }
}

需要进行内部调用的实例，直接通过调用self().xxMethord()就可以事务生效 

public interface ProxySelf<T> {
    /**
     * 取得当前对象的代理.
     * 
     * @return 代理对象,如果未被代理,则抛出 IllegalStateException
     */
    @SuppressWarnings("unchecked")
    default T self() {
        return (T) AopContext.currentProxy();
    }
}
