标签：basename 解析 nts 配置 创建 resource message 文件 always
1.编写国际化配置文件，抽取页面需要显示的国际化消息，以登录页面为例，在resources下创建目录i18n/login,创建目录login.properties,login_zh_CN.properties,login_en_US.properties
2.SpringBoot自动配置好了管理国际化资源文件的组件；配置前缀spring.messages.basename=i18n.login
@Configuration(proxyBeanMethods = false) @ConditionalOnMissingBean(name = AbstractApplicationContext.MESSAGE_SOURCE_BEAN_NAME, search = SearchStrategy.CURRENT) @AutoConfigureOrder(Ordered.HIGHEST_PRECEDENCE) @Conditional(ResourceBundleCondition.class) @EnableConfigurationProperties public class MessageSourceAutoConfiguration { private static final Resource[] NO_RESOURCES = {}; @Bean @ConfigurationProperties(prefix = "spring.messages") public MessageSourceProperties messageSourceProperties() { return new MessageSourceProperties(); } @Bean public MessageSource messageSource(MessageSourceProperties properties) { ResourceBundleMessageSource messageSource = new ResourceBundleMessageSource(); if (StringUtils.hasText(properties.getBasename())) { messageSource.setBasenames(StringUtils .commaDelimitedListToStringArray(StringUtils.trimAllWhitespace(properties.getBasename()))); } if (properties.getEncoding() != null) { messageSource.setDefaultEncoding(properties.getEncoding().name()); } messageSource.setFallbackToSystemLocale(properties.isFallbackToSystemLocale()); Duration cacheDuration = properties.getCacheDuration(); if (cacheDuration != null) { messageSource.setCacheMillis(cacheDuration.toMillis()); } messageSource.setAlwaysUseMessageFormat(properties.isAlwaysUseMessageFormat()); messageSource.setUseCodeAsDefaultMessage(properties.isUseCodeAsDefaultMessage()); return messageSource; } }
webMvc自动配置类中注入了，默认的就是根据请求头带来的区域信息获取Locale进行国际化
@Bean @ConditionalOnMissingBean @ConditionalOnProperty(prefix = "spring.mvc", name = "locale") public LocaleResolver localeResolver() { if (this.mvcProperties.getLocaleResolver() == WebMvcProperties.LocaleResolver.FIXED) { return new FixedLocaleResolver(this.mvcProperties.getLocale()); } AcceptHeaderLocaleResolver localeResolver = new AcceptHeaderLocaleResolver(); localeResolver.setDefaultLocale(this.mvcProperties.getLocale()); return localeResolver; }
其实到这个地方已经能够根据浏览器的默认语言自动切换国际化了
下面我们自定义区域解析器，这里是根据你的定制规则实现的，我的定制规则是将国际化信息放在了请求中
切换国际化的两个按钮
<a class="btn btn-sm" th:href="@{/index.html(l=‘zh_CN‘)}">中文</a> <a class="btn btn-sm" th:href="@{/index.html(l=‘en_US‘)}">English</a>
public class MyLocaleResolver implements LocaleResolver { @Override public Locale resolveLocale(HttpServletRequest request) { String l = request.getParameter("l"); Locale locale = Locale.getDefault(); if(!StringUtils.isEmpty(l)){ String[] split = l.split("_"); locale = new Locale(split[0],split[1]); } return locale; } @Override public void setLocale(HttpServletRequest request, HttpServletResponse response, Locale locale) { } }
最后将自定义的解析器注入spring中
@Bean
public LocaleResolver localeResolver(){
return new MyLocaleResolver();
}
