抽取公共页面

1、抽取公共片段
<div th:fragment="copy">
© 2011 The Good Thymes Virtual Grocery
</div>
2、引入公共片段
<div th:insert="~{footer :: copy}"></div>
~{templatename::selector}：模板名::选择器
~{templatename::fragmentname}:模板名::片段名
3、默认效果：
insert的公共片段在div标签中
如果使用th:insert等属性进行引入，可以不用写~{}：
行内写法可以加上：[[~{}]];[(~{})]；

三种引入公共片段的th属性：
th:insert：将公共片段整个插入到声明引入的元素中
th:replace：将声明引入的元素替换为公共片段
th:include：将被引入的片段的内容包含进这个标签中

<footer th:fragment="copy">
© 2011 The Good Thymes Virtual Grocery
</footer>
引入方式
<div th:insert="footer :: copy"></div>
<div th:replace="footer :: copy"></div>
<div th:include="footer :: copy"></div>

效果
<div>
<footer>
© 2011 The Good Thymes Virtual Grocery
</footer>
</div>

以Customers为例，对应html部分为：

<li class="nav-item">
	<a class="nav-link" href="http://getbootstrap.com/docs/4.0/examples/dashboard/#">
		<svg xmlns="http://www.w3.org/2000/svg" width="24" height="24" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="2" stroke-linecap="round" stroke-linejoin="round" class="feather feather-users">

			<circle cx="9" cy="7" r="4"></circle>
			<path d="M23 21v-2a4 4 0 0 0-3-3.87"></path>
			<path d="M16 3.13a4 4 0 0 1 0 7.75"></path>
		</svg>
		Customers
	</a>
</li>

发现里没有什么，所以重新做一个对应的页面（第二步）。因为点击顾客调到新的页面上要保留原来的导航栏和搜索栏，所以把现有页面的导航栏和搜索栏抽取出来，复用（第三步）。

2.新开页面的后台程序

package Main.controller;


import Main.dao.EmployeeDao;
import Main.entities.Department;
import Main.entities.Employee;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;

import java.util.Collection;

@Controller
public class EmployeeController {
    @Autowired
    EmployeeDao employeeDao;

    //查询所有员工，返回列表页面
    @GetMapping("/emps")
    public String list(Model model){
        //查询到所有员工
        Collection<Employee>  employees = employeeDao.getAll();
        //放到请求域中,这样在页面就可以使用这个变量名
        model.addAttribute("emps",employees);
        //默认拼串，下面的返回相当于： classpath/templates/xxx.html
        return "emp/list";
    }
}

返回语句找到页面的原理：

springboot引用公共模块_xml_02


输入对应的网页，进入了对应的页面，但是没有高亮对应栏，且直接点击栏是没有效果的，说明入口对了，接下来提取公共页面并高亮

springboot引用公共模块_xml_03

3.抽取公共页面

3.1 怎么知道抽取哪部分呢？

直接看网页对应的源码，点击源码，找到想要抽取的部分。

springboot引用公共模块_bootstrap_04


这样就知道搜索栏是哪部分源码了。

3.2抽取

springboot引用公共模块_xml_05

<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
    <nav class="navbar navbar-dark sticky-top bg-dark flex-md-nowrap p-0" th:fragment="topBar">
        <a class="navbar-brand col-sm-3 col-md-2 mr-0" href="http://getbootstrap.com/docs/4.0/examples/dashboard/#">Company name</a>
        <input class="form-control form-control-dark w-100" type="text" placeholder="Search" aria-label="Search">
        <ul class="navbar-nav px-3">
            <li class="nav-item text-nowrap">
                <a class="nav-link" href="http://getbootstrap.com/docs/4.0/examples/dashboard/#">Sign out</a>
            </li>
        </ul>
    </nav>
</body>
</html>

引用：

springboot引用公共模块_ci_06


相同的方法抽取导航栏并应用：

springboot引用公共模块_ci_07


如果用id：注意下面有个#

springboot引用公共模块_bootstrap_08


引用

springboot引用公共模块_ci_09


emps网页对应的list都要引用

springboot引用公共模块_springboot引用公共模块_10


运行后和原来一样，说明抽取成功

springboot引用公共模块_springboot引用公共模块_11

3.3 高亮显示

对应页面代码写判断语句，判断是否高亮

springboot引用公共模块_xml_12


springboot引用公共模块_xml_13


这里能成功的原因是controller里面定义的入口是/emps（映射到emps/list.html），实际在链接上和/emps.html一样，所以能正常显示。

<a class="nav-link active"
th:class="${activeUri=='main.html'?'nav-link active':'nav-link'}"
href="#" th:href="@{/main.html}">

对应页面引用时传入是否高亮的参数

springboot引用公共模块_xml_14


springboot引用公共模块_ci_15

4.对应的代码
