Description

Return the default ClassLoader to use: typically the thread context ClassLoader, if available; the ClassLoader that loaded the ClassUtils class will be used as fallback.

Demo Code



public class Main{
    public static void main(String[] argv) throws Exception{
        System.out.println(getDefaultClassLoader());
    }/* w ww.j av a2 s  . co  m*/
    /**
     * Return the default ClassLoader to use: typically the thread context
     * ClassLoader, if available; the ClassLoader that loaded the ClassUtils
     * class will be used as fallback.
     * <p>Call this method if you intend to use the thread context ClassLoader
     * in a scenario where you absolutely need a non-null ClassLoader reference:
     * for example, for class path resource loading (but not necessarily for
     * <code>Class.forName</code>, which accepts a <code>null</code> ClassLoader
     * reference as well).
     * @return the default ClassLoader (never <code>null</code>)
     * @see java.lang.Thread#getContextClassLoader()
