Question

我正在使用Java和Servlet创建一个简单的Web应用程序，但我似乎无法访问应该可用的地址：http://localhost:8080/Financeiro/oi-mundo。
这是我的Servlet：

import java.io.IOException;
import java.io.PrintWriter;

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 OiMundoServlet
*/
@WebServlet("/oi-mundo")
public class OiMundoServlet extends HttpServlet {
     private static final long serialVersionUID = 1L;

     /**
       * @see HttpServlet#doGet(HttpServletRequest request, 
     HttpServletResponse response)
     */
     protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    // TODO Auto-generated method stub
         PrintWriter out = response.getWriter();
         System.out.println("Ola mamae");
         out.print("<html>");
         out.print("<body><h1>Oi Mundo</h1></body>");
         out.print("</html>");
         out.flush();
     }

 }

这是pom.xml：

 <project xmlns="http://maven.apache.org/POM/4.0.0" 
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 

xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

            <configuration>
                <source>1.8</source>
                <target>1.8</target>
            </configuration>
        </plugin>
    </plugins>
  </build>

  <dependencies>
    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>javax.servlet-api</artifactId>
        <version>3.1.0</version>
        <scope>provided</scope>
    </dependency>
  </dependencies>

</project>

项目和控制台中没有错误，只有警告：
[SetPropertiesRule]{Server/Service/Engine/Host/Context} Setting property 'source' to 'org.eclipse.jst.jee.server:Financeiro' did not find a matching property。
尝试访问地址时，控制台中也不会显示任何消息，但我不确定是否应该这样做。
