SpringBoot、thymeleaf 国际化配置

1、pom.xml 配置

<properties>
        <java.version>1.8</java.version>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
        <thymeleaf.version>3.0.11.RELEASE</thymeleaf.version>
        <thymeleaf-layout-dialect.version>2.3.0</thymeleaf-layout-dialect.version>
</properties>
<dependency>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>

2、application.properties 配置

spring.thymeleaf.prefix=classpath:/templates/
spring.thymeleaf.suffix=.html
spring.thymeleaf.mode=HTML
spring.thymeleaf.encoding=UTF-8
# set to false for hot refresh
spring.thymeleaf.cache=false 

#指定国际化文件位置
spring.messages.basename=i18n.msg

3、resources 目录下创建 i18n 目录并存放国际化内容文件:

3.1 msg.properties

home.welcome=国际化文本内容哈哈。

3.2 msg_zh_CN.properties

home.welcome=国际化文本内容哈哈。

3.3 msg_en_US.properties

home.welcome=welcome good!

4、创建解析类  MyLocaleResolver.java

package com.xrh.demo;

import java.util.Locale;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.web.servlet.LocaleResolver;
import org.thymeleaf.util.StringUtils;

public class MyLocaleResolver implements LocaleResolver {
    @Override
    public Locale resolveLocale(HttpServletRequest request) {
        // 接收语言的参数 - 传进来的就是形如'zh_CN'这样的参数
        String lan = request.getParameter("lan");
        // 使用默认的语言 - 在文中就是login.properties文件里配置的
        Locale locale = Locale.getDefault();
        // 判断接收的参数是否为空,不为空就设置为该语言
        if(!StringUtils.isEmpty(lan)){
            // 将参数分隔 - 假设传进来的是'zh_CN'
            String[] s = lan.split("_");
            // 语言编码:zh   地区编码:CN
            locale = new Locale(s[0],s[1]);
        }
        return locale;
    }

    @Override
    public void setLocale(HttpServletRequest request, HttpServletResponse response, Locale locale) {

    }
}

5、加入容器配置中:

package com.xrh.demo;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.LocaleResolver;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

@Configuration
public class WebMvcConfig implements WebMvcConfigurer {
    @Bean
    public LocaleResolver localeResolver(){
        return new MyLocaleResolver();
    }
}

6、controller类方法:

@GetMapping("/success/{name}")
    public String sucTest(@PathVariable("name") String name,Model model){
        Map<String ,Object> map = new HashMap<>();
        map.put("name", name);
        model.addAttribute("map", map);
        
        return "success";
    }

7、模版页面  templates\success.html

<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
    <title>thymeleaf</title>
</head>
<body> 
    <h1>成功</h1>
    <div th:text="${name}" th:id="${name}" >这是没有引擎展示的数据</div>
    <div th:text="#{home.welcome}" >国际化内容</div>
</body>
</html>

8、运行效果:
