springboot页面国际化 springboot页面国际化

引入依赖pom.xml

org.springframework.boot spring-boot-starter-web org.springframework.boot spring-boot-starter-thymeleaf

导入网页资源，这里给大家推荐一个我自己在使用的页面资源，SB ADMIN-2
html页面放在templates目录下，这是thymeleaf默认的解析目录，其他的样式文件放在static目录下

【springboot页面国际化】接管spring Mvc,自定义url访问路径，可做可不做
建一个config目录，在这里建一个myWebMvcConfig

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.ViewControllerRegistry; import org.springframework.web.servlet.config.annotation.WebMvcConfigurer; @Configuration public class myWebMvcConfig implements WebMvcConfigurer { @Override public void addViewControllers(ViewControllerRegistry registry) {registry.addViewController("/wq").setViewName("register"); //localhost:8080/wq registry.addViewController("/").setViewName("register"); //localhpst:8080/ registry.addViewController("/register.html").setViewName("register"); //localhost:8080/register.html } }

路径可以设置多个，这样只要是这三个url,spring 都会访问register.html
还有一种方式也能实现

import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; @Controller public class demoController { @RequestMapping({"/","/wq"}) public String test(){ return "register"; } }
1. 国际化配置文件：en_US英文，zh_CN中文

  点击左上角加号，便可以添加配置的属性，只要在右边填写相应的中英文即可

5. 配置文件已经写好，如何在我们的页面中使用呢？thyme leaf的作用又来了

首先在你的网页添加这样的头部```html```在所有的html属性前加**th:**就被thymeleaf接管了，根据thymeleaf 语法，获取国际化值使用**#{}**，本地值用**${}**,url用**@{}**![image-20220228101634725](C:\Users\32944\AppData\Roaming\Typora\typora-user-images\image-20220228101634725.png)![image-20220228101806743](C:\Users\32944\AppData\Roaming\Typora\typora-user-images\image-20220228101806743.png)```html 中文 English ```6. 页面和配置文件都准备好了，怎样实现跳转呢？在WebMvcAutoConfiguration.class中```java @Bean @ConditionalOnMissingBean( name = {"localeResolver"} ) public LocaleResolver localeResolver() { if (this.webProperties.getLocaleResolver() == org.springframework.boot.autoconfigure.web.WebProperties.LocaleResolver.FIXED) { return new FixedLocaleResolver(this.webProperties.getLocale()); } else { AcceptHeaderLocaleResolver localeResolver = new AcceptHeaderLocaleResolver(); localeResolver.setDefaultLocale(this.webProperties.getLocale()); return localeResolver; } } ```我们再找到AcceptHeaderLocaleResolver.class,发现它实现了LocaleResolver ```java public class AcceptHeaderLocaleResolver implements LocaleResolver { private final List supportedLocales = new ArrayList(4); @Nullable private Locale defaultLocale; ```那我们就编写自己的LocaleResolver ```java public class myLocaleResolver implements LocaleResolver { @Override public Locale resolveLocale(HttpServletRequest request) {String mylocale=request.getParameter("l"); Locale locale=Locale.getDefault(); if(!StringUtils.isEmpty(mylocale)){ String[] split=mylocale.split("_"); locale=new Locale(split[0],split[1]); } System.out.println("debug====>"+mylocale); return locale; }@Override public void setLocale(HttpServletRequest request, HttpServletResponse response, Locale locale) {} }```然后在spring配置中注入myLocaleResolver```java @Bean public LocaleResolver localeResolver(){ return new myLocaleResolver(); } ```**注意：方法名必须是localeResolver**,**因为源码中名字为localeResolver的bean**
