1、Function函数publicstaticvoidmain(Stringargs){TestControllertnewTestController();newTestController().aaa(3,valuet.bbb(value));}

删除行A表数据如下id(String)       name(String)\1                       aaa2                      bbb3                      ccc\

curlPostJson$curliXPOSTH"'Contenttype':'application/xwwwformurlencoded','charset':'utf8','Accept':'text/plain'"d'json_data{"a":"aaa","b":"bbb","data

★ 数组转Collection使用ApacheJakartaCommonsCollections：1.importorg.apache.commons.collections.CollectionUtils;  3.String\\strArray{"aaa","bbb","ccc"};  4.L

操作linux通过xshell进行连接；基本操作介绍1.shutdownh关机  shutdownr重启2.mkdiraaa新建目录aaa　rmdiraaa删除目录aaa3.cd切换路径  cd~回到home目录文件操作4.touchaaa.txt创建一个文档5.viaaa.txt对aa

1、块级作用域使用let和const2、解构赋值letarr\1,2,3,4,5,6,7,8,9\;let\a,b,c\arr;letobj{foo:'aaa',bar:'bbb'};let{bar,foo}obj;//bar等于'bbb'，foo等于'aaa'（

1、开启Mongodb如图进入D盘：!(https://oscimg.oschina.net/oscnet/850cf1762f99053852417636f1012b6a36c.png)D:\\aaa\\db\\mongodb3.4.15\\binD:\\aaa\\db\\mongodb3.4.15\\data再开一个cmd：D:\

packagecom.fgy.demo;publicclassdemo06{publicstaticvoidmain(Stringargs){Stringstr1"aaa";Stringstr2null;
