篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Spring Boot整合Thymeleaf相关的知识，希望对你有一定的参考价值。
项目结构
一、创建Spring Boot项目，引入Thymeleaf依赖
二、编写配置文件application.properties
# thymeleaf页面缓存设置（默认为true），开发中方便调试应设置为false，上线稳定后应保持默认true
spring.thymeleaf.cache=false
# 配置国际化文件基础名
spring.messages.basename=i18n.login
server.port=8086
三、创建控制类
package com.uos.thymeleaf.controller;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import java.util.Calendar;
@Controller
public class LoginController {
/**
* 获取并封装当前年份跳转到登录页login.html
*/
@GetMapping("/toLoginPage")
public String toLoginPage(Model model){
model.addAttribute("currentYear", Calendar.getInstance().get(Calendar.YEAR));
return "login";
}
}
LoginController
四、创建模板页面并引入资源静态文件
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1,shrink-to-fit=no">
<title>用户登录界面</title>
<link th:href="@{/login/css/bootstrap.min.css}" rel="stylesheet">
<link th:href="@{/login/css/signin.css}" rel="stylesheet">
</head>
<body class="text-center">
<!-- 用户登录form表单 -->
<form class="form-signin">
<img class="mb-4" th:src="@{/login/img/login.jpg}" width="72" height="72">
<h1 class="h3 mb-3 font-weight-normal" th:text="#{login.tip}">请登录</h1>
<input type="text" class="form-control"
th:placeholder="#{login.username}" required="" autofocus="">
<input type="password" class="form-control"
th:placeholder="#{login.password}" required="">
<div class="checkbox mb-3">
<label>
<input type="checkbox" value="remember-me"> [[#{login.rememberme}]]
</label>
</div>
<button class="btn btn-lg btn-primary btn-block" type="submit" th:text="#{login.button}">登录</button>
<p class="mt-5 mb-3 text-muted">© <span th:text="${currentYear}">2018</span>-<span th:text="${currentYear}+1">2019</span></p>
<a class="btn btn-sm" th:href="@{/toLoginPage(l=\'zh_CN\')}">中文</a>
<a class="btn btn-sm" th:href="@{/toLoginPage(l=\'en_US\')}">English</a>
</form>
</body>
</html>
五、使用Thymeleaf配置国际化页面
1、编写多语言国际化文件
login.tip=\\u8BF7\\u767B\\u5F55
login.username=\\u7528\\u6237\\u540D
login.password=\\u5BC6\\u7801
login.rememberme=\\u8BB0\\u4F4F\\u6211
login.button=\\u767B\\u5F55
login.properties
login.tip=Please sign in
login.username=Username
login.password=Password
login.rememberme=Remember me
login.button=Login
login_en_US.properties
2、定制区域化解析器
package com.uos.thymeleaf.config;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.lang.Nullable;
import org.springframework.util.StringUtils;
import org.springframework.web.servlet.LocaleResolver;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.util.Locale;
@Configuration
public class MyLocalResovel implements LocaleResolver {
// 自定义区域解析方式
@Override
public Locale resolveLocale(HttpServletRequest httpServletRequest) {
// 获取页面手动切换传递的语言参数l
String l = httpServletRequest.getParameter("l");
// 获取请求头自动传递的语言参数Accept-Language
String header = httpServletRequest.getHeader("Accept-Language");
Locale locale = null;
// 如果手动切换参数不为空，就根据手动参数进行语言切换，否则默认根据请求头信息切换
if(!StringUtils.isEmpty(l)){
String[] split = l.split("_");
locale=new Locale(split[0],split[1]);
}else {
// Accept-Language: en-US,en;q=0.9,zh-CN;q=0.8,zh;q=0.7
String[] splits = header.split(",");
String[] split = splits[0].split("-");
locale=new Locale(split[0],split[1]);
}
return locale;
}
@Override
public void setLocale(HttpServletRequest httpServletRequest, @Nullable
HttpServletResponse httpServletResponse, @Nullable Locale locale) {
}
// 将自定义的MyLocalResovel类重新注册为一个类型LocaleResolver的Bean组件
@Bean
public LocaleResolver localeResolver(){
return new MyLocalResovel();
}
}
