dynamic proxy is fundamentally the core of Java technologies model, AOP model were implemented. Now we use the Spring EJB3 Hibernate, and most have a dynamic proxy framework where, but expression isn't apparent when in use.
JDK dynamic proxy itself give the API, although not prominent due to performance or functionality, so these frameworks would be to specialized byte code library Code Era Library,Office Pro Plus 2007, Code Era Library, currently you'll find CGLib (according to ASM) and Javassist.
efficiency now than ever before prior to JDK six.0 version of one.four has significantly improved, I lately utilized this write-up Why do you think CGLib proxies are quicker than JDK Proxies? The check code are around the JDK and CGLib Javassist 3 dynamic agent properties had been examined and found fantastic outcomes, to not say that certain database efficiency bytecode faster than the JDK, at least Javassist slow.
JDK and CGLib check code inside the TSS article, I test to Javassist, and JDK are:
public course 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, Approach m, Approach proceed, 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 results are as follows:
JDK six and CGLib cglib-nodep-2.two.jar comparative outcomes:
JDK Proxy: one,049,937 calls / s
CGLIB: 2,820,130 calls / s
If you're utilizing previous versions of cglib, faster efficiency:
JDK Proxy: 1,037,575 calls / s
CGLIB: three,112,727 calls / s
the JDK 6 and JavaAssit three.11 Test outcomes are as follows:
JDK Proxy: 1,037,Office Home And Stude/nt 2010,575 calls / s
JAVAASSIST: 626,695 calls / s
JAVAASSIST even slower than JDK six, fantastic.
worse is,Office 2007 Activation Key, Hibernate three.3 or later on to make use of JavaAssit, considering that the two are JBoss, due to it,Office 2007 Enterprise Key,
Tapstry5 also use JAVAASSIST, Javassist vs. Each Other Bytecode Library Available
optimize performance of each and every move, little accumulation, will type a significant impact.
