    }
    // The constructor for `Cell` is private, and it's in such a central location I don't really
    // want to make it public. Brace yourselves.

Example 3 with MethodInterceptor

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

the class ProxyFactory method getProxyObj.

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

        hancer.setCallbacks(methodInterceptors);
    } else {
