dynamic proxy is fundamentally the core of Java technology model, AOP model were applied. Now we use the Spring EJB3 Hibernate, and most possess a dynamic proxy framework through which, but expression is not apparent when in use.
JDK dynamic proxy itself provide the API, although not prominent because of overall performance or performance, so these frameworks would be to specialized byte code library Code Era Library, Code Era Library, currently there are actually CGLib (according to ASM) and Javassist.
efficiency now than ever before JDK six.0 version of one.four has significantly improved, I recently utilized this post Why do you think CGLib proxies are faster than JDK Proxies? The check code are on the JDK and CGLib Javassist three dynamic agent properties were examined and discovered incredible results, to not say that particular database overall performance bytecode quicker than the JDK,
Buy Office 2007, a minimum of Javassist slow.
JDK and CGLib test code in the TSS write-up, I check to Javassist, and JDK are:
public class ProxyPerformanceComparison2 {
public static void main (String [] args) throws Exception {
Callable jdkProxy = (Callable)
Proxy.newProxyInstance (ClassLoader.getSystemClassLoader (), new Class []
Callable.class,
new JdkHandler (new Counter ()));
ProxyFactory f = new ProxyFactory ();
f.setInterfaces (new Class [] Callable.class);
Class c = f.createClass ();
Callable cglibProxy = (Callable) c.newInstance ();
((ProxyObject) cglibProxy). setHandler
(new JavaAssitInterceptor (new Counter ()));
for (int i2 = 0; i2
public Object invoke
(Object self,
Office 2010 Keygen, Method m, Strategy move forward, Object [] args) throws Throwable
return m.invoke (delegate, args);
}
static class Counter implements Callable {
int count = 0;
public Integer call () throws Exception
return count + +;
}
}
test The outcomes are as follows:
JDK six and CGLib cglib-nodep-2.two.jar comparative results:
JDK Proxy: 1,049,937 calls / s
CGLIB: two,820,130 calls / s
Should you be employing prior versions of cglib, faster performance:
JDK Proxy: 1,037,575 calls / s
CGLIB: three,112,
Windows 7 Starter Key,727 calls / s
the JDK 6 and JavaAssit three.11 Check results are as follows:
JDK Proxy: 1,037,575 calls / s
JAVAASSIST: 626,695 calls / s
JAVAASSIST even slower than JDK six, incredible.
even worse is,
Microsoft Office 2007 Enterprise, Hibernate three.3 or later on to make use of JavaAssit,
Office Professional Plus, since the two are JBoss, due to it,
Tapstry5 also use JAVAASSIST, Javassist vs. Every single Other Bytecode Library Available
optimize performance of each and every move, small accumulation, will form a huge effect.
