Returns true if the given class is a proxy class.

Usage

From source file:Main.java

/**
 * Helper method used to weed out dynamic Proxy types; types that do
 * not expose concrete method API that we could use to figure out
 * automatic Bean (property) based serialization.
 *//*  ww  w  .java 2  s  . co  m*/
public static boolean isProxyType(Class<?> type) {
    // Then: well-known proxy (etc) classes
    if (Proxy.isProxyClass(type)) {
        return true;
    }
    String name = type.getName();
    // Hibernate uses proxies heavily as well:
    if (name.startsWith("net.sf.cglib.proxy.") || name.startsWith("org.hibernate.proxy.")) {
        return true;
    }
    // Not one of known proxies, nope:
    return false;
