# 1、国际化资源 #

### 使用IDEA创建资源组 ###

# 2、编写配置 #

`application.yml` 增加国际化目录配置

增加配置类 从请求头获取多语言关键字

/** * 国际化配置 * * @author Lion Li */
    @Configuration
    public class I18nConfig { 
    
    	@Bean
    	public LocaleResolver localeResolver() { 
    		return new I18nLocaleResolver();
    	}
    
    	/** * 获取请求头国际化信息 */
    	static class I18nLocaleResolver implements LocaleResolver { 
    
    		@NotNull
    		@Override
    		public Locale resolveLocale(HttpServletRequest httpServletRequest) { 
    			String language = httpServletRequest.getHeader("content-language");
    			Locale locale = Locale.getDefault();
    			if (StrUtil.isNotBlank(language)) { 
    				String[] split = language.split("_");
    				locale = new Locale(split[0], split[1]);
    			}
    			return locale;
    		}
    
    		@Override
    		public void setLocale(@NotNull HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Locale locale) { 
    
    		}
    	}
    }

# 3、用法详解 #

在 Header 请求头 增加上下文语言参数 content-language  
参数需与国际化配置文件后缀对应  
如 zh\_CN en\_US 等

# 4、测试 #

### 编写测试类 ###

/** * 测试国际化 * * @author Lion Li */
    @RestController
    @RequestMapping("/demo/i18n")
    public class TestI18nController { 
    
    	@Autowired
    	private MessageSource messageSource;
    
    	/** * 通过code获取国际化内容 * code为 messages.properties 中的 key * * 测试使用 user.register.success */
    	@GetMapping()
    	public String get(String code) { 
    		return messageSource.getMessage(code, new Object[]{ }, LocaleContextHolder.getLocale());
    	}
    }

### 测试接口 ###
