测试发现新的代理类生成模块不支持泛型，cglib是支持的；可以ProxyManager.me().setProxyFactory(new CglibProxyFactory());改为cglib的方式；

package jfdemo;

import com.jfinal.aop.Interceptor;

import com.jfinal.aop.Invocation;

public class EmptyInterceptor implements Interceptor {

@Override

public void intercept(Invocation inv) {

inv.invoke();

}

}

package jfdemo;

import com.jfinal.aop.Before;

public class A<T> {

private T obj;

@Before(EmptyInterceptor.class)

public T getObj() { // 泛型不支持

return obj;

}

@Before(EmptyInterceptor.class)

public void setObj(T obj) { // 泛型不支持

this.obj = obj;

}

}

package jfdemo;

import com.jfinal.aop.Aop;

import com.jfinal.aop.Before;

import com.jfinal.ext.proxy.CglibProxyFactory;

import com.jfinal.proxy.ProxyManager;

public class B extends A<String> {

@Before(EmptyInterceptor.class)

public void show() {

System.out.println(getObj());

}

public static void main(String[] args) {

//ProxyManager.me().setProxyFactory(new CglibProxyFactory());

B b = Aop.get(B.class);

b.setObj("aaa");

System.out.println(b.getClass().getName());

b.show();

}

}

生成的代码如下：

package jfdemo;

import com.jfinal.aop.Invocation;

public class B$$EnhancerByJFinal extends B {

public  void show() {

Invocation inv = new Invocation(this, 1L,

args -> {

B$$EnhancerByJFinal.super.show(

);

return null;

}

);

inv.invoke();

}

public  T getObj() {

Invocation inv = new Invocation(this, 2L,

args -> {

return  B$$EnhancerByJFinal.super.getObj(

);

}

);

inv.invoke();

return inv.getReturnValue();

}

public  void setObj(T p0) {

Invocation inv = new Invocation(this, 3L,

args -> {

B$$EnhancerByJFinal.super.setObj(

(T)args[0]

);

return null;

}

, p0);

inv.invoke();

}

}
