2. jsp （這里不一樣，因為jsp還是以前的，所有要建一個web項目，然后會有web.xml文件）
2.1 pom.xml 引包

<!--
JSTL（JSP Standard Tag Library，JSP標准標簽庫)是一個不斷完善的開放源代碼的JSP標簽庫，是由apache的jakarta小組來維護的。
JSTL只能運行在支持JSP1.2和Servlet2.3規范的容器上，如tomcat 4.x。在JSP 2.0中也是作為標准支持的。
不然報異常信息：
javax.servlet.ServletException: Circular view path [/helloJsp]:
would dispatch back to the current handler URL [/helloJsp] again. Check your ViewResolver setup! (Hint: This may be the result of an unspecified view, due to default view name generation.)
