MyEclipse2014中的web项目部署到tomcat中

一、MyEclipse中的web project目录结构

 

 

二、MyEclipse配置Tomcat插件

注：MyEclipse是完全破解的

1.点击下图中Preferences

 

2.搜索tomcat,配置tomcat7运行环境(如果电脑中没有安装Tomcat7,则需要先安装Tomcat7服务器)

 

3、选择服务器运行模式，选debug模式(开发模式)

 

4、启动tomcat7服务器，点击start按钮，控制台有信息输出

 

三、创建web工程

1、创建一个新工程

2、对工程进行设置，然后点击next

3、我们应将java代码放在src中，编译后的class文件会自动放置到class文件夹中，并会在将来被部署到tomcat服务器中，点击next

4、访问路径设置

图中的1指定部署到tomcat时，应用的名称(默认与工程名一致)，即将来会在tomcat下有个MyServlet的文件夹，我们访问时url是这样的http://locaolhost/MyServlet。若将该名称更改，则URL也应该做出相应的改变

图3是可选得，因为我们使用了web3.1，直接使用在java代码中使用注解技术来配置工程，或者也可以通过web.xml配置整个工程

5、编写MyServlet类，实现Servlet接口

点击next

点击Finish

33         PrintWriter out = response.getWriter();
34         out.println("<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.01 Transitional//EN\">");
35         out.println("<HTML>");

62     public void doPost(HttpServletRequest request, HttpServletResponse response)
63             throws ServletException, IOException {
64 
65         response.setContentType("text/html");

6、浏览器访问

/MySerlet是开始开始建立工程时指定的context root，即我们的应用名称。/HeollServlet是我们在该应用下的访问路径(一个应用下可以有多个Servlet)

四、热部署问题

为了解决我们修改工程之后需要重启Tomcat的问题，可以使用热部署来实现

1.修改tomcat安装目录下的context.xml文件

 

 在context标签中加入以下内容

　<Context reloadable="true">

 2.修改tomcat启动参数

 　　打开Eclipse下的Preferences，找到tomcat7的设置，修改其JDK参数
