我们此时只要写一个Servlet就可以了:
public class UpdateMenuServlet extends HttpServlet {
/**
*
*/
private static final long serialVersionUID = 1L;
// 构造方法
public UpdateMenuServlet() {
super();
}
// 销毁方法
public void destroy() {
super.destroy();
}
// 响应Get请求
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/xml");
PrintWriter out = response.getWriter();
// 实例化dao
UpdateDao dao = new UpdateDaoImpl();
// 获得菜谱列表
List<Menu> list = dao.getMenuList();
// 拼XML格式数据
out.println("<?xml version=‘1.0‘ encoding=‘UTF-8‘?>");
// 根节点
out.println("<menulist>");
for (int i = 0; i <list.size(); i++) {
Menu m = list.get(i);
out.println("<menu>");
// 菜谱编号
out.print("<id>");
out.print(m.getId());
out.println("</id>");
// 分类
out.print("<typeId>");
out.print(m.getTypeId());
out.println("</typeId>");
// 名称
out.print("<name>");
out.print(m.getName());
out.println("</name>");
// 图片路径
out.print("<pic>");
out.print(m.getPic());
out.println("</pic>");
// 价格
out.print("<price>");
out.print(m.getPrice());
out.println("</price>");
// 备注
out.print("<remark>");
out.print(m.getRemark());
out.println("</remark>");
out.println("</menu>");
}
out.println("</menulist>");
out.flush();
out.close();
}
// 响应Post请求
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
doGet(request,response);
}
// 初始化方法
public void init() throws ServletException {
}
}
然后就是直接在浏览器中输入这个Servlet的具体网址就可以了
<?xml version="1.0" encoding="UTF-8" ?>
- <menulist>
- <menu>
<id>1</id>
<typeId>1</typeId>
<name>水煮鱼</name>
<pic>test</pic>
<price>20</price>
<remark>test</remark>
</menu>
- <menu>
<id>2</id>
<typeId>2</typeId>
<name>凉拌西红柿</name>
<pic>tets</pic>
<price>10</price>
<remark>test</remark>
</menu>
- <menu>
<id>3</id>
<typeId>3</typeId>
<name>tofu</name>
<pic>test</pic>
<price>8</price>
<remark>test</remark>
</menu>
</menulist>
