参数:

o1 -

o2 -

true if either o1==o2 or (o1!=null and o1.equals(o2))

isNullOrEmpty

public static boolean isNullOrEmpty(java.lang.Object[] array)

concat

public static <E> E[] concat(E[] array1,
                             E[] array2,
                             java.lang.Class<E> itemClass)

beanToString

public static java.lang.String beanToString(java.lang.Object bean)

Utility method to create a simple String representation of a JavaBean Object by showing all properties p which can be called by getP() on the Object.

参数:

bean -

返回:

String representation of the form className(p1=value,p2=value,...)
