Eclipse创建一个Maven Web项目

在这篇文章中，我们将演示如何在Eclipse IDE中使用maven创建一个动态Web项目。

使用的工具和技术 

  • Eclipse Jee Oxygen
  • Maven 3.3.3
  • JavaSE 1.8
  • Servlet API 3.1.0
  • Apache Tomcat 7.0.47 (Embeded)

下面开始一步一步在Eclipse中使用maven创建一个web项目。

第1步

转到 New 菜单 Other.. -> Maven -> Maven Project ，然后单击 Next 。如下图所示 -

第2步

在New Maven Project向导中，选择Create a simple project并指定项目保存的目录(如：F:\worksp\Maven\webproject)，然后单击Next。如下图所示 -

第3步

在下一个向导中，添加项目信息，如下所示，然后单击Finish。

 

第4步

打开pom.xml文件并在其中添加servlet依赖项和Tomcat maven插件，如下代码所示，pom.xml

在更改pom.xml文件之后，更新maven web项目。

要更新web maven项目，请右键单击项目名称(如：webproject)-> Maven -> Update Project... 来更新项目。

第5步

查看maven web项目结构，如下图所示 -

第6步

现在，创建一个包：com.yiibai.servlet，并在此包下创建一个HelloWorldServlet类，并在其中写入以下代码。文件：HelloWorldServlet.java -

@WebServlet("/hello")
public class HelloWorldServlet extends HttpServlet {
 
    private static final long serialVersionUID = 1L;
 
    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        resp.setContentType("text/plain");
        resp.getWriter().write("Hello World! Maven Web Project Example.");
    }
}

　　

第7步

使用以下maven命令构建项目。

mvn clean install
Shell

要在Eclipse IDE中执行maven命令，请右键点击项目名称，打开Run菜单 -> Run Configuration..以创建新配置。

在运行配置向导中，双击Maven Build并提供配置信息(Name，Base directory和Goals)，如下图所示。

然后点击运行(Run)并在控制台中输出结果如下 -

第8步

使用以下命令运行嵌入式tomcat服务器。

mvn tomcat7:run
Shell

要在Eclipse IDE中执行maven命令，请创建一个新的配置，如下图所示 -

现在运行配置启动tomcat服务器。 控制台输出如下图所示 -

第9步

打开浏览器并在地址栏中输入URL: http://localhost:8080/hello ，得到以下结果 -
