Scala学习笔记-Servlet环境搭建
之前用的Scala的IDE,发现没有Web开发插件,所以重新下载了个J2EE的eclipse,然后安装scala插件。
还有准备好Tomcat,配置好Eclipse的web开发环境。
Tomcat我用的8,java也是8,eclipse是4.5.1 。
之后新建web项目,在web项目上右键->Configure->Add Scala Nature ,然后就可以使用scala了。
之后右键新建servlet,这个servlet是java的,基于注解的,然后run一下,就能正常访问这个servlet。
之后新建scala的class,
下面直接上代码。
项目结构:
First代码:
package day02; import java.io.IOException; import javax.servlet.ServletException; import javax.servlet.annotation.WebServlet; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; /** * Servlet implementation class First */ @WebServlet("/First") public class First extends HttpServlet { private static final long serialVersionUID = 1L; /** * Default constructor. */ public First() { // TODO Auto-generated constructor stub } /** * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse * response) */ protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { // TODO Auto-generated method stub response.getWriter().append("Served at: ").append(request.getContextPath()); } /** * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse * response) */ protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { // TODO Auto-generated method stub doGet(request, response); } }
ServletA代码:
package day02 import java.io.IOException; import javax.servlet.ServletException; import javax.servlet.annotation.WebServlet; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; @WebServlet(Array("/A")) class ServletA extends HttpServlet { override def doGet(req: HttpServletRequest, res: HttpServletResponse) { res.getWriter().print("hello,this is a servlet written by scala"); } }
部署的时候可能需要单独加上scala的依赖包。
以上就是这次的内容。
