CGlib概述：
cglib（）是一个强大的,高性能,高质量的Code生成类库。它可以在运行期扩展Java类与实现Java接口。
cglib封装了asm，可以在运行期动态生成新的class。
cglib用于AOP，jdk中的proxy必须基于接口，cglib却没有这个限制。
CGlib应用：
以一个实例在简单介绍下cglib的应用。
我们模拟一个虚拟的场景，关于信息的管理。
1）原始需求是任何人可以操作信息的create，update，delete，query操作。
InfoManager.java－－封装对信息的操作
public class InfoManager {
// 模拟查询操作
public void query() {
System.out.println("query");
}
// 模拟创建操作
public void create() {
System.out.println("create");
}
// 模拟更新操作
public void update() {
System.out.println("update");
}
// 模拟删除操作
public void delete() {
System.out.println("delete");
}
}
InfoManagerFactory.java－－工厂类
public class InfoManagerFactory {
private static InfoManager manger = new InfoManager();
/**
* 创建原始的InfoManager
*
* @return
*/
public static InfoManager getInstance() {
return manger;
}
}
client.java－－供客户端调用
public class Client {
public static void main(String[] args) {
Client c = new Client();
c.anyonecanManager();
}
/**
* 模拟：没有任何权限要求，任何人都可以操作
*/
public void anyonecanManager() {
System.out.println("any one can do manager");
InfoManager manager = InfoManagerFactory.getInstance();
doCRUD(manager);
separatorLine();
}
/**
* 对Info做增加／更新／删除／查询操作
*
* @param manager
*/
private void doCRUD(InfoManager manager) {
manager.create();
manager.update();
manager.delete();
manager.query();
}
/**
* 加一个分隔行，用于区分
*/
private void separatorLine() {
System.out.println("################################");
}
}
至此，没有涉及到cglib的内容，因为需求太简单了，但是接下来，需求发生了改变，要求：
2）只有一个叫“maurice”的用户登录，才允许对信息进行create，update，delete，query的操作。
怎么办？难道在每个方法前，都加上一个权限判断吗？这样重复逻辑太多了，于是乎想到了Proxy（代理模式），但是原先的InfoManager也没有实现接口，不能采用jdk的proxy。那么cglib在这边就要隆重登场。
一旦使用cgblig，只需要添加一个MethodInterceptor的类以及修改factory代码就可以实现这个需求。
AuthProxy.java－－权限校验代理类
public class AuthProxy implements MethodInterceptor {
private String name; // 会员登录名
public AuthProxy(String name) {
this.name = name;
}
/**
* 权限校验，如果会员名为:maurice，则有权限做操作，否则提示没有权限
*/
@Override
public Object intercept(Object obj, Method method, Object[] args, MethodProxy proxy) throws Throwable {
if (!"maurice".equals(this.name)) {
System.out.println("AuthProxy:you have no permits to do manager!");
return null;
}
return proxy.invokeSuper(obj, args);
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
InfoManagerFactory.java－－代码变动如下：
public class InfoManagerFactory {
/**
* 创建带有权限检验的InfoManager
*
* @param auth
* @return
*/
public static InfoManager getAuthInstance(AuthProxy auth) {
Enhancer enhancer = new Enhancer();
enhancer.setSuperclass(InfoManager.class);
enhancer.setCallback(auth);
return (InfoManager) enhancer.create();
}
}
client.java－－代码修改如下
public class Client {
public static void main(String[] args) {
Client c = new Client();
c.haveNoAuthManager();
c.haveAuthManager();
}
/**
* 模拟：登录会员没有权限
*/
public void haveNoAuthManager() {
System.out.println("the loginer's name is not maurice,so have no permits do manager
");
InfoManager noAuthManager = InfoManagerFactory.getAuthInstance(new AuthProxy("maurice1"));
doCRUD(noAuthManager);
separatorLine();
}
/**
* 模拟：登录会员有权限
*/
public void haveAuthManager() {
System.out.println("the loginer's name is maurice,so have permits do manager");
InfoManager authManager = InfoManagerFactory.getAuthInstance(new AuthProxy("maurice"));
doCRUD(authManager);
separatorLine();
}
/**
* 对Info做增加／更新／删除／查询操作
*
* @param manager
*/
private void doCRUD(InfoManager manager) {
manager.create();
manager.update();
manager.delete();
manager.query();
}
/**
* 加一个分隔行，用于区分
*/
private void separatorLine() {
System.out.println("################################");
}
} 执行下代码,发现这时client端中已经加上了权限校验。
同样是InfoManager，为什么这时能多了权限的判断呢？Factory中enhancer.create()返回的到底是什么对象呢？这个疑问将在第三部分CGlib中解释。
这边的代码,其实是介绍了cglib中的enhancer功能.
到这里，参照上面的代码，就可以使用cglib带来的aop功能了。但是为了更多介绍下cglib的功能，模拟需求再次发生变化：
3）由于query功能用户maurice才能使用，招来其他用户的强烈的抱怨，所以权限再次变更，只有create，update，delete，才需要权限保护,query任何人都可以使用。
怎么办？采用AuthProxy，使得InfoManager中的所有方法都被代理，加上了权限的判断。当然，最容易想到的办法，就是在AuthProxy的intercept的方法中再做下判断，如果代理的method是query，不需要权限验证。这么做，可以，但是一旦逻辑比较复杂的时候，intercept这个方法要做的事情会很多，逻辑会异常的复杂。
幸好，cglib还提供了CallbackFilter。使用CallbackFilter，可以明确表明，被代理的类（InfoManager）中不同的方法，被哪个拦截器（interceptor)拦截。
AuthProxyFilter.java
public class AuthProxyFilter implements CallbackFilter {
private static final int AUTH_NEED = 0;
private static final int AUTH_NOT_NEED = 1;
/**
*
* 选择使用的proxy
* 如果调用query函数，则使用第二个proxy
* 否则，使用第一个proxy
*
*/
@Override
public int accept(Method method) {
if ("query".equals(method.getName())) {
return AUTH_NOT_NEED;
}
return AUTH_NEED;
}
} 这段代码什么意思？其中的accept方法的意思是说，如果代理的方法是query()，那么使用第二个拦截器去拦截，如果代理的方法不是query(),那么使用第一个拦截器去拦截。所以我们只要再写一个拦截器，不做权限校验就行了。（其实，cglib中的NoOp.INSTANCE就是一个空的拦截器，只要配置上这个就可以了。）
InfoManagerFactory.java－－代码修改如下：（配置不同的拦截器和filter）
public class InfoManagerFactory {
/**
* 创建不同权限要求的InfoManager
*
* @param auth
* @return
*/
public static InfoManager getSelectivityAuthInstance(AuthProxy auth) {
Enhancer enhancer = new Enhancer();
enhancer.setSuperclass(InfoManager.class);
enhancer.setCallbacks(new Callback[] { auth, NoOp.INSTANCE });
enhancer.setCallbackFilter(new AuthProxyFilter());
return (InfoManager) enhancer.create();
}
}
记住：setCallbacks中的拦截器(interceptor)的顺序，一定要和CallbackFilter里面指定的顺序一致！！切忌。
Client.java
public class Client {
public static void main(String[] args) {
Client c = new Client();
c.selectivityAuthManager();
}
/**
* 模拟：没有权限的会员，可以作查询操作
*/
public void selectivityAuthManager() {
System.out.println("the loginer's name is not maurice,so have no permits do manager except do query operator");
InfoManager authManager = InfoManagerFactory.getSelectivityAuthInstance(new AuthProxy("maurice1"));
doCRUD(authManager);
separatorLine();
}
/**
* 对Info做增加／更新／删除／查询操作
*
* @param manager
*/
private void doCRUD(InfoManager manager) {
manager.create();
manager.update();
manager.delete();
manager.query();
}
/**
* 加一个分隔行，用于区分
*/
private void separatorLine() {
System.out.println("################################");
}
} 此时，对于query的权限校验已经被去掉了。
通过一个模拟需求，简单介绍了cglib aop功能的使用。
CGlib应用非常广，在spring，hibernate等框架中，被大量的使用。
CGlib原理：
cglib神奇吗？其实一旦了解cglib enhancer的原理，一切就真相大白了。
刚才在第二部分中，有个疑问：enhancer.create()到底返回了什么对象？
其实在刚才的例子中，cglib在代码运行期，动态生成了InfoManager的子类，并且根据CallbackFilter的accept方法，覆写了InfoManager中的所有方法－－去执行相应的MethodInterceptor的intercept方法。
有兴趣的朋友可以看看我反编译的InfoManager的子类，就可以很明白知道具体的实现了。（需要有耐心才可以）
