ProxyFactory

ProxyFactory Hierarchy:

AbstractProxyFactory

public <T> T getProxy(Invoker<T> invoker) throws RpcException {
Class<?>[] interfaces = null;
// createProxy时创建invoker时已将interface传入
String config = invoker.getUrl().getParameter("interfaces");
if (config != null && config.length() > 0) {
String[] types = Constants.COMMA_SPLIT_PATTERN.split(config);
if (types != null && types.length > 0) {
interfaces = new Class<?>[types.length + 2];
interfaces[0] = invoker.getInterface();
interfaces[1] = EchoService.class;
for (int i = 0; i < types.length; i ++) {
interfaces[i + 1] = ReflectUtils.forName(types[i]);
}
}
}
if (interfaces == null) {
interfaces = new Class<?>[] {invoker.getInterface(), EchoService.class};
}
// 调用子类的实现
return getProxy(invoker, interfaces);

JavassistProxyFactory

public <T> T getProxy(Invoker<T> invoker, Class<?>[] interfaces) {
return (T) Proxy.getProxy(interfaces).newInstance(new InvokerInvocationHandler(invoker));
}

getProxy的相关代码:

public static Proxy getProxy(Class<?>... ics)
{
return getProxy(ClassHelper.getCallerClassLoader(Proxy.class), ics);
}

动态类的实现:

public static Proxy getProxy(ClassLoader cl, Class<?>... ics)
{
//some ops...
try
{
ccp = ClassGenerator.newInstance(cl);
Set<String> worked = new HashSet<String>();
List<Method> methods = new ArrayList<Method>();
// 反射获取interface的相关信息并build code string，然后交给javassist动态生成实现类。
for(int i=0;i<ics.length;i++)
{
if( !Modifier.isPublic(ics[i].getModifiers()) )
{
String npkg = ics[i].getPackage().getName();
if( pkg == null )
{
pkg = npkg;
}
else
{
if( !pkg.equals(npkg) )
throw new IllegalArgumentException("non-public interfaces from different packages");
}
}
ccp.addInterface(ics[i]);
for( Method method : ics[i].getMethods() )
{
String desc = ReflectUtils.getDesc(method);
if( worked.contains(desc) )
continue;
worked.add(desc);
int ix = methods.size();
Class<?> rt = method.getReturnType();
Class<?>[] pts = method.getParameterTypes();
StringBuilder code = new StringBuilder("Object[] args = new Object[").append(pts.length).append("];");
for(int j=0;j<pts.length;j++)
code.append(" args[").append(j).append("] = ($w)$").append(j+1).append(";");
// 注意这里 handler.invoke(),代理的统一处理
code.append(" Object ret = handler.invoke(this, methods[" + ix + "], args);");
if( !Void.TYPE.equals(rt) )
code.append(" return ").append(asArgument(rt, "ret")).append(";");
methods.add(method);
ccp.addMethod(method.getName(), method.getModifiers(), rt, pts, method.getExceptionTypes(), code.toString());
}
}
if( pkg == null )
pkg = PACKAGE_NAME;
// 接口的实现类
String pcn = pkg + ".proxy" + id;
ccp.setClassName(pcn);
ccp.addField("public static java.lang.reflect.Method[] methods;");
ccp.addField("private " + InvocationHandler.class.getName() + " handler;");
ccp.addConstructor(Modifier.PUBLIC, new Class<?>[]{ InvocationHandler.class }, new Class<?>[0],"handler=$1;"); // $1等表示传入的参数，具体参考javassist官方文档
ccp.addDefaultConstructor();
Class<?> clazz = ccp.toClass();
clazz.getField("methods").set(null, methods.toArray(new Method[0]));
// 生成当前Proxy的子类，实现newInstance()方法
String fcn = Proxy.class.getName() + id;
ccm = ClassGenerator.newInstance(cl);
ccm.setClassName(fcn);
ccm.addDefaultConstructor();
ccm.setSuperClass(Proxy.class);
ccm.addMethod("public Object newInstance(" + InvocationHandler.class.getName() + " h){ return new " + pcn + "($1); }");
Class<?> pc = ccm.toClass();
proxy = (Proxy)pc.newInstance();
}
// some ops...
return proxy;
