spring boot thymeleaf簡單使用

spring4推薦使用thymeleaf模板進行開發,剛好最近需要使用,一起來學習一下

1.加入maven依賴

<dependency>
   <groupId>net.sourceforge.nekohtml</groupId>
   <artifactId>nekohtml</artifactId>
   <version>1.9.22</version>
</dependency>
<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>

2.簡單配置application.yml

spring:
    thymeleaf:
            mode: LEGACYHTML5
            prefix: classpath:/templates/
            suffix: .html
            cache: false
            encoding: utf-8

3.編寫html

<!DOCTYPE html>
<html lang="zh" xmlns:th="http://www.thymeleaf.org">
<META HTTP-EQUIV="pragma" CONTENT="no-cache"> 
<META HTTP-EQUIV="Cache-Control" CONTENT="no-cache, must-revalidate"> 
<META HTTP-EQUIV="expires" CONTENT="0">
<head th:fragment="head">
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    <title>title</title>
    <meta name="renderer" content="webkit">
    <meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
    <meta http-equiv="Access-Control-Allow-Origin" content="*">
    <meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1">
    <meta name="apple-mobile-web-app-status-bar-style" content="black">
    <meta name="apple-mobile-web-app-capable" content="yes">
    <meta name="format-detection" content="telephone=no">
    <link rel="icon" href="favicon.ico">
    <link rel="stylesheet"  th:href="@{/layui/css/layui.css}">
    <link rel="stylesheet" href="//at.alicdn.com/t/font_tnyc012u2rlwstt9.css" media="all" />
    <link rel="stylesheet"  media="all" th:href="@{/css/main.css}"/>
    <script src="" th:src="@{/js/jquery-1.8.0.min.js}"></script>

    <script type="text/javascript">
        var WEB_ROOT = '[[${#httpServletRequest.contextPath}]]' + "/";
    </script>

</head>
<body>

</body>
</html>

我這裡寫的是一個簡單的公共的html用到了th:fragment="head"用來定義用於載入的塊,在我們需要使用的頁面使用

<head th:replace="header :: head">就可以替換head標籤裡的內容,當然還可以使用th:include

th:include 和 th:replace的區別

th:include和th:replace都可以引入模組,兩者的區別在於  th:include:引入子模組的children,依然保留父模組的tag。  th:replace:引入子模組的所有,不保留父模組的tag。

在js中還寫了一串js程式碼,用來獲取專案名

<script type="text/javascript"> var WEB_ROOT = '[[${#httpServletRequest.contextPath}]]' + "/"; </script>

這樣的話需要在調後臺服務的地方拼寫WEB_ROOT就不用擔心把路徑搞錯了

4.編寫controller

@Controller
@RequestMapping("/test")
public class TestController {
    @RequestMapping("/toIndex")
    public String toIndex(){
        return "index";
    }
}

在controller裡面返回檢視就可以了
