一、目的

針對(duì)不同地區(qū)，設(shè)置不同的語(yǔ)言信息。

SpringBoot國(guó)際化配置文件默認(rèn)放在classpath:message.properties，如果自定義消息配置文件，需要application.properties或application.yml中設(shè)置spring.messages.basename的值。

二、步驟

在src/main/resources 下建i18n文件夾

在i18n文件夾中建立messages.properties 找不到語(yǔ)言配置時(shí)，使用此文件

hello=你好_默認(rèn)

在i18n文件夾中建立messages_en_US.properties 英文語(yǔ)言配置

hello=hello_English

在i18n文件夾中建立messages_zh_CN.properties 中文語(yǔ)言配置

hello=你好_中文

MessageConfig.java

對(duì)消息的配置

package com.spring.security.config.spring;import java.util.Locale;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.springframework.beans.factory.annotation.Value;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;import org.springframework.context.i18n.LocaleContext;import org.springframework.context.support.ResourceBundleMessageSource;import org.springframework.util.Assert;import org.springframework.web.servlet.LocaleResolver;import org.springframework.web.servlet.i18n.AbstractLocaleContextResolver;import org.springframework.web.servlet.i18n.LocaleChangeInterceptor;import org.springframework.web.servlet.i18n.SessionLocaleResolver;@Configurationpublic class MessageConfig extends AbstractLocaleContextResolver{@Value('${spring.messages.basename}')public String[] basenames;@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;} @Bean public LocaleResolver localeResolver() { SessionLocaleResolver slr = new SessionLocaleResolver(); slr.setDefaultLocale(Locale.SIMPLIFIED_CHINESE); return slr; } /** * 國(guó)際化，設(shè)置url識(shí)別參數(shù) * * @return */ @Bean public LocaleChangeInterceptor localeChangeInterceptor() { LocaleChangeInterceptor lci = new LocaleChangeInterceptor(); lci.setParamName('lang'); return lci; }@Overridepublic LocaleContext resolveLocaleContext(HttpServletRequest request) {return null;}@Overridepublic void setLocaleContext(HttpServletRequest request, HttpServletResponse response,LocaleContext localeContext) {}}

SpringUtils.java

Spring工具類，用于獲取ApplicationContext

package com.spring.security.common.utils;import org.springframework.beans.BeansException;import org.springframework.context.ApplicationContext;import org.springframework.context.ApplicationContextAware;import org.springframework.stereotype.Service;/** * Spring容器 */@Servicepublic class SpringUtils implements ApplicationContextAware { private static ApplicationContext context = null; @Override public void setApplicationContext(ApplicationContext applicationContext) throws BeansException { if (context == null) { context = applicationContext; } } /** * 獲取容器 * * @return 容器 */ public static ApplicationContext getContext() { return context; }}

MessageUtils.java

封裝獲取message的工具類

package com.spring.security.common.utils;import java.util.Locale;import org.springframework.context.i18n.LocaleContextHolder;import org.springframework.context.support.ReloadableResourceBundleMessageSource;public class MessageUtils {public static String getMessage(String code) { Locale locale = LocaleContextHolder.getLocale(); ReloadableResourceBundleMessageSource reloadableResourceBundleMessageSource = new ReloadableResourceBundleMessageSource(); String message = reloadableResourceBundleMessageSource.getMessage(code, null, locale); return message;}}

** WebMvcConfig.java**

mvc配置，解決跨域，接口中文亂碼，添加語(yǔ)言攔截器

package com.spring.security.config.spring;import java.nio.charset.Charset;import java.util.List;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;import org.springframework.http.converter.HttpMessageConverter;import org.springframework.http.converter.StringHttpMessageConverter;import org.springframework.web.servlet.config.annotation.CorsRegistry;import org.springframework.web.servlet.config.annotation.InterceptorRegistry;import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;import org.springframework.web.servlet.i18n.LocaleChangeInterceptor;@Configurationpublic class WebMvcConfig extends WebMvcConfigurationSupport {@Autowiredprivate LocaleChangeInterceptor localeChangeInterceptor;/** * 解決跨域 */@Overrideprotected void addCorsMappings(CorsRegistry registry) {registry.addMapping('/**').allowedHeaders('*').allowedMethods('*').allowedOrigins('*').allowCredentials(true);}/** * 配置消息轉(zhuǎn)換器 * 解決返回String亂碼 */@Overrideprotected void configureMessageConverters(List<HttpMessageConverter<?>> converters) {super.configureMessageConverters(converters);converters.add(responseBodyConverter());}@Bean public HttpMessageConverter<String> responseBodyConverter() { return new StringHttpMessageConverter(Charset.forName('UTF-8')); }@Overrideprotected void addInterceptors(InterceptorRegistry registry) {super.addInterceptors(registry);registry.addInterceptor(localeChangeInterceptor);}}

三、測(cè)試

測(cè)試接口：

package com.spring.security.controller;import org.springframework.web.bind.annotation.GetMapping;import org.springframework.web.bind.annotation.RestController;import com.spring.security.common.utils.I18nUtils;@RestControllerpublic class TestController {@GetMapping('/test')public String doTest() {return I18nUtils.getMessage('hello');}}

以上就是本文的全部?jī)?nèi)容，希望對(duì)大家的學(xué)習(xí)有所幫助，也希望大家多多支持好吧啦網(wǎng)。
