1.功能模块细分
接下来实现 后台账户管理
功能,我们继续完善 iot-cloud-web-admin
项目。
首先,我们将功能模块细化为:auth
和 iot
,将涉及账户相关功能放在 auth
模块下,将涉及物联网相关功能放在 iot
模块下。
然后,构建模块结构:
- 在
net.work100.training.stage2.iot.cloud.web.admin.web.controller
包下新增auth
和iot
包 - 在
webapp/WEB-INF/views
文件夹下新增auth
和iot
文件夹
2.新建ManagerController控制器
在 web.controller.auth
包下新建 ManagerController
类,代码如下:
package net.work100.training.stage2.iot.cloud.web.admin.web.controller.auth;
import net.work100.training.stage2.iot.cloud.web.admin.service.AuthManagerService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
/**
* <p>Title: ManagerController</p>
* <p>Description: </p>
* <p>Url: http://www.work100.net/training/monolithic-project-iot-cloud-admin.html</p>
*
* @author liuxiaojun
* @date 2020-03-01 14:01
* ------------------- History -------------------
* <date> <author> <desc>
* 2020-03-01 liuxiaojun 初始创建
* -----------------------------------------------
*/
@Controller
@RequestMapping(value = "auth/manager")
public class ManagerController {
@Autowired
private AuthManagerService authManagerService;
@RequestMapping(value = "list", method = RequestMethod.GET)
public String list(){
return "auth/manager_list";
}
}
说明:
ManagerController
类上的注解 @RequestMapping(value = "auth/manager")
- 作用:控制器下的所有方法的请求路径都将增加前缀,即:
auth/manager/*
- 举例:
list
方法,请求路径为:auth/manager/list
3.新建manager_list.jsp页面
在 views/auth/
文件夹下新建 manager_list.jsp
页面,代码如下:
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>后台账户</title>
</head>
<body>
账户列表
</body>
</html>
4.运行并查看效果
启动 Tomcat
登录后,点击菜单 后台账户 - 查新列表
,界面如下图:
5.通过include引入公用文件
5.1.通用布局
参照我们的 首页布局
,可见界面布局上有一些通用部分,如下图:
其中红色区域为每个页面都包含的,蓝色区域为每个页面特有的。
既然每个页面都包含红色区域的 通用部分
,那么我们就需要将其提取出来,这里将使用 <jsp:include >
来实现。
5.2.提取通用布局到文件
在 views
文件夹下新增一个 includes
文件夹,然后提取下表的通用内容为文件,并存储到 includes
下:
文件位置 | 作用 |
---|---|
includes/resources_head.jsp | 在页面 header 标签中引入 资源
|
includes/resources_body.jsp | 在页面 body 标签中引入 资源
|
includes/layout_header.jsp | 页面顶部通用部分 |
includes/layout_left.jsp | 页面左侧通用部分(菜单) |
includes/layout_footer.jsp | 页面底部通用部分(版权信息) |

5.3.重构 main.jsp
将 main.jsp
文件的通用部分替换为我们提取出来的 includes
文件,重构后的 main.jsp
文件代码如下:
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<!DOCTYPE html>
<html>
<head>
<title>控制台 | IoT-Admin</title>
<jsp:include page="includes/resources_head.jsp" />
</head>
<body class="hold-transition sidebar-mini">
<div class="wrapper">
<jsp:include page="includes/layout_header.jsp" />
<jsp:include page="includes/layout_left.jsp" />
<!-- Content Wrapper. Contains page content -->
<div class="content-wrapper">
<!-- Content Header (Page header) -->
<div class="content-header">

5.4.重构 auth/manager_list.jsp
将通用布局文件包含到 auth/manager_list.jsp
文件中,代码如下:
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<!DOCTYPE html>
<html>
<head>
<title>查询列表 | 后台账户 | IoT-Admin</title>
<jsp:include page="../includes/resources_head.jsp" />
</head>
<body class="hold-transition sidebar-mini">
<div class="wrapper">
<jsp:include page="../includes/layout_header.jsp" />
<jsp:include page="../includes/layout_left.jsp" />
<!-- Content Wrapper. Contains page content -->
<div class="content-wrapper">
<!-- Content Header (Page header) -->
<div class="content-header">
<div class="container-fluid">
<div class="row mb-2">
<div class="col-sm-6">
<h1 class="m-0 text-dark">查询列表</h1>
</div><!-- /.col -->
<div class="col-sm-6">
<ol class="breadcrumb float-sm-right">
<li class="breadcrumb-item"><a href="#">后台账户</a></li>
<li class="breadcrumb-item active">查询列表</li>
</ol>
</div><!-- /.col -->
</div><!-- /.row -->
</div><!-- /.container-fluid -->
</div>
<!-- /.content-header -->
<!-- Main content -->
<div class="content">
<div class="container-fluid">
列表内容
</div>
<!-- /.container-fluid -->
</div>
<!-- /.content -->
</div>
<!-- /.content-wrapper -->
<jsp:include page="../includes/layout_footer.jsp" />
</div>
<!-- ./wrapper -->
<jsp:include page="../includes/resources_body.jsp" />
</body>
</html>
重构后的页面效果如下图:
