感觉这种模式转换成seajs module,写法更加优美

	(function (root, factory) {
	//seajs module define
	define(function(require, exports, module) {
	var jQuery = require('jquery');
	factory(jQuery);
	});
	}(this, function ($) {
	//export module
	return $;
	}));

JPA @onetomany 级联删除Many端



	When we use JPA @oneToMany

	if you remove a dependent object from a OneToMany collection it will not be deleted, JPA1.0 don’t support it itself, it requires that you explicitly call remove() on it.
	In JPA2.0 ,you need do add “orphanRemoval” to “@OneToMany” ,
	just like this:
	@OneToMany(mappedBy = "A", orphanRemoval=true,cascade = CascadeType.ALL)
