在浏览器输入：http://localhost:8080/myapp/mytestMap.html
访问到mytestMap.jsp页面，单击左上角的“操作”按钮，结果如下：
在输入框中输入测试数据，点击提交，将会提交至insert_map.jsp页面，并在insert_map.jsp页面上显示出数据库中所有的点（包括刚刚添加的这个点），效果如下图：
再次在浏览器中访问地图页面，可以看到地图上已经多出了刚刚添加的那个点，如下图：
至此，基本操作算是完成。
后续需要做的工作有：
1，使点击提交后仍然显示在当前页面，且对地图进行刷新。
2，完善delete功能、修改功能
3，点击“操作”按钮后可以选择添加、删除或修改。 |
