1.安装好之后开始创建项目
2.选择Maven类型项目，选择JDK
3.设置Maven坐标
略......
4.需要给新项目Add Framework support
5.选择Java EE项目模板
6.项目结构
修改pom.xml文件增加以下依赖
<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.11</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.1.0</version>
</dependency>
<dependency>
<groupId>javax.servlet.jsp</groupId>
<artifactId>jsp-api</artifactId>
<version>2.2</version>
</dependency>
</dependencies>
7.配置Tomcat
8.需要注意的就是热部署问题。需要选择On frame dectivation为：Update classes and resources需要注意第一次不会有这个选项，需要先配置Deployment才可以
9.设置Deployment
10.如果需要可以设置Application context
11.运行Tomcat
12.jsp页面正确展现在浏览器中
13.新建一个Servlet
14.这里需要注意的是选中Create Java EE6 annotated class会默认创建带上注解的Serlvet，这里我们不选
不选的话会自动帮我们生成<servlet>标签，选了的话就没有了
15.在web.xml中配置Servlet
public class HelloServlet extends HttpServlet {
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html;charset=utf-8");
response.setCharacterEncoding("utf-8");
PrintWriter out = response.getWriter();
out.print(new Date().toLocaleString());
}
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
this.doPost(request,response);
}
}
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
version="3.1">
<servlet>
<servlet-name>HelloServlet</servlet-name>
<servlet-class>com.winner.HelloServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>HelloServlet</servlet-name>
<url-pattern>/hello</url-pattern>
</servlet-mapping>
</web-app>
16.部署方法
