java通过反射调用实现类

package com.commons.util;

import java.lang.reflect.Constructor;
import java.lang.reflect.InvocationTargetException;

@SuppressWarnings("all")
public class ReflectionUtil {

public static Object getBean(String className) {
try {
Class cls = Class.forName(className);
Constructor cons = cls.getConstructor();
Object object = cons.newInstance(new String[]{});
return object;
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (NoSuchMethodException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SecurityException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (InstantiationException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalAccessException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalArgumentException e) {

e.printStackTrace();
} catch (InvocationTargetException e) {
// TODO Auto-generated catch block
e.printStackTrace();

return null;
