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。
