自定义分页标签结合spring mvc、bootstrap、mybatis、mysql的使用

最终效果如图：

pager.tld

	Pager
	1.0
	page
	
	
		createPager
		com.test.utils.Pager
		JSP
		
			curPage
			true
			true
			java.lang.Integer
		
		
			totalPage
			true
			true
			java.lang.Integer
		
		
			pageSize
			true
			true
			java.lang.Integer
		
		
			totalCount
			true
			true
			java.lang.Integer
		
		
			formId
			true
			true
			java.lang.String
