当前环境下thymeleaf无疑是使用最为广泛的模板引擎,随着spring完善,出现了许多优秀的页面渲染技术,jsp技术已经越来越少人使用,thymeleaf无疑是主流,一起来学习thymeleaf整合thymeleaf.
引入jar包
当我们不知道pom依赖是什么的时候,可以去maven中心仓库中搜索,点进去复制坐标,粘贴到pom中即可.
在项目pom文件中加入依赖 这里注意引入的是spring-boot-starter-thymeleaf,引错会报找不到映射.
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
这里我们选择版本号,让maven自动导入.我们可以看到默认导入了最新版3.0.11.RELEASE版

编写入门案例
本案例参考https://github.com/wuyouzhuguli/SpringAll thymeleaf章节书写.
首先建立一个bean与一个控制器
package com.springboot.blog.bean;
public class Account {
private String account;
private String name;
private String password;
private String accountType;
private String tel;
public Account(String account, String name, String password, String accountType, String tel) {
super();
this.account = account;
this.name = name;
this.password = password;
this.accountType = accountType;
this.tel = tel;
}
public String getAccount() {
return account;
}
public void setAccount(String account) {
this.account = account;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getAccountType() {
return accountType;
}
public void setAccountType(String accountType) {
this.accountType = accountType;
}
public String getTel() {
return tel;
}
public void setTel(String tel) {
this.tel = tel;
}
}
package com.springboot.blog.controller;
import com.springboot.blog.bean.Account;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import java.util.ArrayList;
import java.util.List;
@Controller
public class IndexController {
@RequestMapping("/account")
public String index(Model m) {
List<Account> list = new ArrayList<Account>();
list.add(new Account("KangKang", "康康", "e10adc3949ba59abbe56e", "超级管理员", "17777777777"));
list.add(new Account("Mike", "麦克", "e10adc3949ba59abbe56e", "管理员", "13444444444"));
list.add(new Account("Jane","简","e10adc3949ba59abbe56e","运维人员","18666666666"));
list.add(new Account("Maria", "玛利亚", "e10adc3949ba59abbe56e", "清算人员", "19999999999"));
m.addAttribute("accountList",list);
return "account";
}
}

table {
margin: 20px 40px 20px 0px;
width: 100%;
border-collapse: collapse;
border-spacing: 0;
table-layout:auto;
word-wrap: break-word;
}
table>tbody>tr:nth-of-type(odd) {
background-color: #F7F7F7
}
th, td {
padding: 8px;
text-align: left;
vertical-align: middle;
font-weight: normal;
font-size: 12px;
border-bottom: 1px solid #fff;
}
th {
padding-bottom: 10px;
color: #fff;
font-weight: 700;
background: rgba(66, 185, 131, .9)
}
td {
border-bottom-width: 1px
}
<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
<title>account</title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<link rel="stylesheet" th:href="@{/css/style.css}" type="text/css">
</head>
<body>
<table>
<tr>
<th>no</th>
<th>account</th>
<th>name</th>
<th>password</th>
<th>accountType</th>
<th>tel</th>
</tr>
<tr th:each="list,stat : ${accountList}">
<td th:text="${stat.count}"></td>
<td th:text="${list.account}"></td>
<td th:text="${list.name}"></td>
<td th:text="${list.password}"></td>
<td th:text="${list.accountType}"></td>
<td th:text="${list.tel}"></td>
</tr>
</table>
</body>
</html>
修改yml配置
spring:
thymeleaf:
cache: false #关闭缓存
运行http://127.0.0.1:8080/account

成功配置第一个thymeleaf 页面.
自己遇到的问题
在配置所有代码后请求提示This application has no explicit mapping for /error, so you are seeing this as a fallback.,在排除application入口文件位置没有错误的情况下,最终发现是yml配置出现问题,可能在网上复制的配置存在特殊字符还是啥的.清空yal,运行正常,解决.
