SpringBoot：整合Thymeleaf及国际化处理
一，官方链接html
* Thymeleaf文档链接：https://www.thymeleaf.org/doc/tutorials/3.0/usingthymeleaf.htmljava
* SpringBoot整合链接（搜索Thymeleaf便可）：https://docs.spring.io/spring-boot/docs/2.1.1.RELEASE/reference/htmlsingle/web
二，模板依赖spring
<!-- 整合thymeleaf --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-thymeleaf</artifactId> </dependency>
三，配置文件浏览器
### thymeleaf配置信息 # 不启用缓存 spring.thymeleaf.cache=false # 文件地址前缀 spring.thymeleaf.prefix=classpath:/static/thymeleaf/ # 文件地址后缀, 此处使用html文件 spring.thymeleaf.suffix=.html # 以utf-8进行编码 spring.thymeleaf.encoding=UTF-8 # 文件类型 spring.thymeleaf.servlet.content-type=text/html
四，thymeleaf.html文件缓存
<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<!-- 用于演示国际化 -->
<h1 th:text="#{locale.message}"></h1>
<table>
<tr>
<th>USERNAME</th>
<th>PASSWORD</th>
<th>AGE</th>
</tr>
<!-- 遍历后台返回集合 -->
<tr th:each="user : ${users}">
<!-- el表达式获取对象属性 -->
<td th:text="${user.userName}"></td>
<td th:text="${user.password}"></td>
<td th:text="${user.age}"></td>
</tr>
</table>
</body>
</html>
五，后台代码springboot
* Controllerruby
package com.gupao.springboot.themyleaf.controller;
import com.gupao.springboot.entitys.UserVO;
import com.gupao.springboot.themyleaf.service.IUserThyService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.context.MessageSourceProperties;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import java.util.List;
/**

**/
@Controller
public class UserThyController {
@Autowired
private IUserThyService userThyService;
@RequestMapping("userThy")
public String findUser(Model model) {
List<UserVO> lstUser = userThyService.findUser();
model.addAttribute("users", lstUser);
return "userDetails";
}
}
* Servicemybatis
package com.gupao.springboot.themyleaf.service.impl;
import com.gupao.springboot.entitys.UserVO;
import com.gupao.springboot.themyleaf.mapper.IUserThyMapper;
import com.gupao.springboot.themyleaf.service.IUserThyService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.List;
/**

**/
@Service
public class UserThyService implements IUserThyService {
@Autowired
private IUserThyMapper userThyMapper;
@Override
public List<UserVO> findUser() {
return userThyMapper.findUser();
}
}
* Mapperapp
package com.gupao.springboot.themyleaf.mapper;
import com.gupao.springboot.entitys.UserVO;
import java.util.List;
/**
* @author pj_zhang
* @create 2019-01-02 21:48
**/
public interface IUserThyMapper {
List<UserVO> findUser();
}
* mapper.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace="com.gupao.springboot.themyleaf.mapper.IUserThyMapper">
<select id="findUser" resultType="com.gupao.springboot.entitys.UserVO">
SELECT
USERNAME AS userName,
PASSWORD AS PASSWORD,
AGE AS age
FROM
user_t
</select>
</mapper>
六，页面展现
七，SpringBoot+Thymeleaf实现国际化
1，SpringBoot读取文件默认配置类，默认从messages.properties读取配置信息
2，内置国际化处理措施，获取浏览器当前语言，以后识别对应的配置文件自动进行装载
* 默认配置文件messages.properties必须存在，否则国际化加载会出问题。（我的实验）
* 装载文件名称：messages + "_" + http头信息的Content-Language属性（"-"解析为"_"进行装载），如图
3，messages_en.properties
locale.message = Welcome
4，messages_zh_CN.properties
locale.message = 欢迎
5，界面访问
* 默认中文界面下访问
* 修改英文界面
-- 设置 --> 高级 --> 语言 --> 语言
-- 设置英语为当前语言，并移到顶部，以后重启
* 切换后从新访问以下，由于英文下对应的http头属性值为en，因此对应文件名称为messages_en.properties
