springboot2国际化配置

SpringBoot2 国际化配置

原来用SpringBoot1的时候，配置自定义国际化位置的时候，直接使用spring.messages.basename属性就可以，但是在使用SpringBoot2的时候发现该属性不生效了，后来经过多方查阅，发现springboot2的默认的配置不生效，无论怎么配置都会走默认的messages，这个时候就需要重新定义messageSource，定义代码如下：

@Configuration
public class I18nConfig extends AbstractLocaleContextResolver {
	

    public static final String LOCALE_SESSION_ATTRIBUTE_NAME = SessionLocaleResolver.class.getName() + ".LOCALE";
    public static final String TIME_ZONE_SESSION_ATTRIBUTE_NAME = SessionLocaleResolver.class.getName() + ".TIME_ZONE";

    
	@Value("${spring.messages.basename}")
	public String[] basenames;

	
	/**
	 * 用于解析消息的策略接口，支持这些消息的参数化和国际化。
	 */
	@Bean(name = "messageSource")
	public ResourceBundleMessageSource resourceBundleMessageSource() {
		ResourceBundleMessageSource source = new ResourceBundleMessageSource();
		if (basenames != null) {
			for (int i = 0; i < basenames.length; i++) {
				String basename = basenames[i];
				Assert.hasText(basename, "Basename must not be empty");
				this.basenames[i] = basename.trim();
			}
			source.setBasenames(basenames);
		} else {
			this.basenames = new String[0];
			source.setBasename(basenames[0]);
		}
		source.setDefaultEncoding("UTF-8");
		source.setUseCodeAsDefaultMessage(true);
		return source;
	}
	

	@Override
	public void setLocale(HttpServletRequest request, HttpServletResponse response, Locale locale) {
		this.setLocaleContext(request, response, locale != null ? new SimpleLocaleContext(locale) : null);
	}


	@Override
	public LocaleContext resolveLocaleContext(HttpServletRequest arg0) {
		return null;
	}

	@Override
	public void setLocaleContext(HttpServletRequest request, HttpServletResponse response, LocaleContext localeContext) {
		Locale locale = null;
		TimeZone timeZone = null;
		if (localeContext != null) {
			locale = localeContext.getLocale();
			if (localeContext instanceof TimeZoneAwareLocaleContext) {
				timeZone = ((TimeZoneAwareLocaleContext) localeContext).getTimeZone();
			}
		}
		WebUtils.setSessionAttribute(request, LOCALE_SESSION_ATTRIBUTE_NAME, locale);
		WebUtils.setSessionAttribute(request, TIME_ZONE_SESSION_ATTRIBUTE_NAME, timeZone);
	}

}

对应的拦截器配置：

/**

@Configuration
public class WebMvcConfiguration implements WebMvcConfigurer {


    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/static/**").addResourceLocations("classpath:/static/");
        registry.addResourceHandler("/templates/**").addResourceLocations("classpath:/templates/");
    }

    @Bean
    public LocaleResolver localeResolver() {
        SessionLocaleResolver slr = new SessionLocaleResolver();
        slr.setDefaultLocale(Locale.SIMPLIFIED_CHINESE);
        return slr;
    }

    @Bean
    public LocaleChangeInterceptor localeChangeInterceptor() {
        LocaleChangeInterceptor lci = new LocaleChangeInterceptor();
        lci.setParamName("lang");
        return lci;
    }

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(localeChangeInterceptor());
    }
}
