CGlib 是一个强大的, 高性能和高质量代码生成工具, 通常可以用它在运行期, 扩展已有Java代码类的功能或者实现某些接口; 并不能代理静态方法;

JDK: 1.8 CGLib

代码示例

1 . 需要被代理的类

package com.test.reflect;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import java.time.LocalDateTime;

/**
 * @author Hinsteny
 * @Describtion
 * @date 2016/12/2
 * @copyright: 2016 All rights reserved.
 */
public class ScholarImpl implements Scholar {

    static final private Logger logger = LoggerFactory.getLogger(ScholarImpl.class);

    public static String printTime(){
        logger.info("Now time is {}", LocalDateTime.now().toString());
        return "Time";
    }

    @Override
    public String searching(String theme) {
        logger.info("Scholar do search {}", theme);
        return "success";
    }
}

package com.test.reflect;

/**
 * @author Hinsteny
 * @Describtion
 * @date 2016/12/2
 * @copyright: 2016 All rights reserved.
 */
public interface Scholar {

    String LOCAL = "CHIBA";

    String  searching(String theme);

    default String infoLocal(){
        return this.LOCAL;
    }
}

2 . 实现MethodInterceptor接口可以进行方法执行拦截代理

package com.test.reflect.CGLib;

import net.sf.cglib.proxy.MethodInterceptor;
import net.sf.cglib.proxy.MethodProxy;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import java.lang.reflect.Method;

/**
 * @author Hinsteny
 * @Describtion
 * @date 2016/12/7
 * @copyright: 2016 All rights reserved.
 */
public class MyInterceptor implements MethodInterceptor {

    static final private Logger logger = LoggerFactory.getLogger(MyInterceptor.class);

    @Override
    public Object intercept(Object obj, Method method, Object[] objects, MethodProxy methodProxy) throws Throwable {
        logger.info("do something before method {}", method.getName());
        logger.info("obj: {}", obj.getClass().getName());  //由CGLib动态生成的代理类的class name
        logger.info("method: {}", methodProxy.getSignature().getName()); //被代理对象中此次调用的方法名称
        logger.info("methodProxy: {}", methodProxy.getSuperName()); //代理对象中此次调用的方面名称

        Object object = methodProxy.invokeSuper(obj, objects);  //调用代理类实例上的methodProxy方法的父类方法
        logger.info("do something after method {}", method.getName());
        return object;
    }
}

3 . 生成代理示例的工具类

package com.test.reflect.CGLib;

import net.sf.cglib.proxy.Enhancer;
import net.sf.cglib.proxy.MethodInterceptor;

/**
 * @author Hinsteny
 * @Describtion
 * @date 2016/12/7
 * @copyright: 2016 All rights reserved.
 */
public class CGLibProxy {

    /**
     *
     * @param obj 被委托代理的对象
     * @param callback 代理注入的逻辑
     * @param <T> 被委托代理对象的类型
     * @return
     */
    public static <T> T getInstance(final T obj, MethodInterceptor callback){
        Enhancer enhancer = new Enhancer();  //增强类
        //不同于JDK的动态代理。它不能在创建代理时传obj对 象，obj对象必须被CGLIB包来创建
        enhancer.setSuperclass(obj.getClass()); //设置被代理类字节码（obj将被代理类设置成父类；作为产生的代理的父类传进来的）。CGLIB依据字节码生成被代理类的子类
        enhancer.setCallback(callback); //设置回调函数，即一个方法拦截
        return (T)enhancer.create(); //创建代理类
    }

    /**
     *
     * @param type 被委托代理的类型
     * @param callback 代理注入的逻辑
     * @param <T> 被委托代理对象的具体类型
     * @return
     */
    public static <T> T getInstance(final Class<T> type, MethodInterceptor callback){
        Enhancer enhancer = new Enhancer();  //增强类
        //不同于JDK的动态代理。它不能在创建代理时传obj对 象，obj对象必须被CGLIB包来创建
        enhancer.setSuperclass(type); //设置被代理类字节码
        enhancer.setCallback(callback); //设置回调函数，即一个方法拦截
        return (T)enhancer.create(); //创建代理类
    }

}

4 . 生成代理对象的关键代码

// 创建代理对象实例
private Object createHelper() {
    this.validate();
    if(this.superclass != null) {
        this.setNamePrefix(this.superclass.getName());
    } else if(this.interfaces != null) {
        this.setNamePrefix(this.interfaces[ReflectUtils.findPackageProtected(this.interfaces)].getName());
    }

    return super.create(KEY_FACTORY.newInstance(this.superclass != null?this.superclass.getName():null, ReflectUtils.getNames(this.interfaces), this.filter, this.callbackTypes, this.useFactory, this.interceptDuringConstruction, this.serialVersionUID));
}
//组装生成代理对象
public void generateClass(ClassVisitor v) {
            ClassEmitter ce = new ClassEmitter(v);
            Method newInstance = ReflectUtils.findNewInstance(this.keyInterface);
            if(!newInstance.getReturnType().equals(KeyFactory.class$java$lang$Object == null?(KeyFactory.class$java$lang$Object = KeyFactory.class$("java.lang.Object")):KeyFactory.class$java$lang$Object)) {
                throw new IllegalArgumentException("newInstance method must return Object");
            } else {
                Type[] parameterTypes = TypeUtils.getTypes(newInstance.getParameterTypes());
                ce.begin_class(46, 1, this.getClassName(), KeyFactory.KEY_FACTORY, new Type[]{Type.getType(this.keyInterface)}, "<generated>");
                EmitUtils.null_constructor(ce);
                EmitUtils.factory_method(ce, ReflectUtils.getSignature(newInstance));
                int seed = 0;
                CodeEmitter e = ce.begin_method(1, TypeUtils.parseConstructor(parameterTypes), (Type[])null);
                e.load_this();
                e.super_invoke_constructor();
                e.load_this();

                int hc;
                for(hc = 0; hc < parameterTypes.length; ++hc) {
                    seed += parameterTypes[hc].hashCode();
                    ce.declare_field(18, this.getFieldName(hc), parameterTypes[hc], (Object)null);
                    e.dup();
                    e.load_arg(hc);
                    e.putfield(this.getFieldName(hc));
                }

                e.return_value();
                e.end_method();
                e = ce.begin_method(1, KeyFactory.HASH_CODE, (Type[])null);
                hc = this.constant != 0?this.constant:KeyFactory.PRIMES[Math.abs(seed) % KeyFactory.PRIMES.length];
                int hm = this.multiplier != 0?this.multiplier:KeyFactory.PRIMES[Math.abs(seed * 13) % KeyFactory.PRIMES.length];
                e.push(hc);

                for(int fail = 0; fail < parameterTypes.length; ++fail) {
                    e.load_this();
                    e.getfield(this.getFieldName(fail));
                    EmitUtils.hash_code(e, parameterTypes[fail], hm, this.customizer);
                }

                e.return_value();
                e.end_method();
                e = ce.begin_method(1, KeyFactory.EQUALS, (Type[])null);
                Label var11 = e.make_label();
                e.load_arg(0);
                e.instance_of_this();
                e.if_jump(153, var11);

                int i;
                for(i = 0; i < parameterTypes.length; ++i) {
                    e.load_this();
                    e.getfield(this.getFieldName(i));
                    e.load_arg(0);
                    e.checkcast_this();

                    EmitUtils.not_equals(e, parameterTypes[i], var11, this.customizer);
                }

                e.push(1);
                e.return_value();
                e.mark(var11);
                e.push(0);
                e.return_value();
                e.end_method();
                e = ce.begin_method(1, KeyFactory.TO_STRING, (Type[])null);
                e.new_instance(Constants.TYPE_STRING_BUFFER);
                e.dup();
                e.invoke_constructor(Constants.TYPE_STRING_BUFFER);

                for(i = 0; i < parameterTypes.length; ++i) {
                    if(i > 0) {
                        e.push(", ");
                        e.invoke_virtual(Constants.TYPE_STRING_BUFFER, KeyFactory.APPEND_STRING);
                    }
