idea国际化语言编写

步骤：

1）、编写国际化配置文件，抽取页面需要显示的国际化消息![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80Mjg0NzYyNg_size_16_color_FFFFFF_t_70]  
例如：index.btn=登陆  
index.password=密码  
index.remember=记住我？  
index.tip=请登录  
index.username=�用户名

2）、SpringBoot自动配置好了管理国际化资源文件的组件；

@ConfigurationProperties(prefix = "spring.messages")
    public class MessageSourceAutoConfiguration { 
        
        /** * Comma-separated list of basenames (essentially a fully-qualified classpath * location), each following the ResourceBundle convention with relaxed support for * slash based locations. If it doesn't contain a package qualifier (such as * "org.mypackage"), it will be resolved from the classpath root. */
    	**private String basename = "messages";  
        //我们的配置文件可以直接放在类路径下叫messages.properties；**
        
        @Bean
    	public MessageSource messageSource() { 
    		ResourceBundleMessageSource messageSource = new ResourceBundleMessageSource();
    		if (StringUtils.hasText(this.basename)) { 
                //设置国际化资源文件的基础名（去掉语言国家代码的）
    			messageSource.setBasenames(StringUtils.commaDelimitedListToStringArray(
    					StringUtils.trimAllWhitespace(this.basename)));
    		}
    		if (this.encoding != null) { 
    			messageSource.setDefaultEncoding(this.encoding.name());
    		}
    		messageSource.setFallbackToSystemLocale(this.fallbackToSystemLocale);
    		messageSource.setCacheSeconds(this.cacheSeconds);
    		messageSource.setAlwaysUseMessageFormat(this.alwaysUseMessageFormat);
    		return messageSource;
    	}

    3）、去页面获取国际化的值；

    效果：根据浏览器语言设置的信息切换了国际化；
    如果出现乱码，解决方法如下

    浏览器中英文切换不了的解决方法：

    原理：
    	国际化Locale（区域信息对象）；LocaleResolver（获取区域信息对象）；
    
    ```java
    		@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;
    		}
    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

    public class MyLocaleResolver implements LocaleResolver { 
    
        @Override
        public Locale resolveLocale(HttpServletRequest request) { 
            //获取区域语言标志
            String l = request.getParameter("l");
            // 获取默认的区域语言标志
            Locale locale = Locale.getDefault();
            if(!StringUtils.isEmpty(l)){ 
    // new Locale(语言,国家);
                String[] split = l.split("_");
                locale = new Locale(split[0],split[1]);
            }
            return locale;
        }
    
        @Override
        public void setLocale(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Locale locale) { 
    
        }
    }
