Example 16 with Enhancer

use of net.sf.cglib.proxy.Enhancer in project blade by biezhi.

the class ProxyFactory method getProxyObj.

/*
	 * 获得代理对象

public static Object getProxyObj(Class<?> clazz) throws Exception {
    Enhancer hancer = new Enhancer();
    // 设置代理对象的父类

    if (null != methodInterceptors && methodInterceptors.length > 0) {
        hancer.setCallbacks(methodInterceptors);
