这篇文章主要介绍了SpringBoot消息国际化配置实现过程解析,文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下
一、目的
针对不同地区，设置不同的语言信息。
SpringBoot国际化配置文件默认放在classpath:message.properties，如果自定义消息配置文件，需要application.properties或application.yml中设置spring.messages.basename的值。
二、步骤
在src/main/resources 下建i18n文件夹
在i18n文件夹中建立messages.properties 找不到语言配置时，使用此文件
hello=你好_默认
在i18n文件夹中建立messages_en_US.properties 英文语言配置
hello=hello_English
在i18n文件夹中建立messages_zh_CN.properties 中文语言配置
hello=你好_中文
MessageConfig.java
对消息的配置
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; @Configuration public 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; } /** * 国际化，设置url识别参数 * * @return */ @Bean public LocaleChangeInterceptor localeChangeInterceptor() { LocaleChangeInterceptor lci = new LocaleChangeInterceptor(); lci.setParamName("lang"); return lci; } @Override public LocaleContext resolveLocaleContext(HttpServletRequest request) { return null; } @Override public void setLocaleContext(HttpServletRequest request, HttpServletResponse response, LocaleContext localeContext) { } }
SpringUtils.java
Spring工具类，用于获取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 */ @Service public class SpringUtils implements ApplicationContextAware { private static ApplicationContext context = null; @Override public void setApplicationContext(ApplicationContext applicationContext) throws BeansException { if (context == null) { context = applicationContext; } } /** * 获取容器 * * @return 容器 */ public static ApplicationContext getContext() { return context; } }
MessageUtils.java
封装获取message的工具类
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，解决跨域，接口中文乱码，添加语言拦截器
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; @Configuration publi<b style="color:transparent">来源gao@!dai!ma.com搞$$代^@码网</b>c class WebMvcConfig extends WebMvcConfigurationSupport { @Autowired private LocaleChangeInterceptor localeChangeInterceptor; /** * 解决跨域 */ @Override protected void addCorsMappings(CorsRegistry registry) { registry .addMapping("/**") .allowedHeaders("*") .allowedMethods("*") .allowedOrigins("*") .allowCredentials(true); } /** * 配置消息转换器 * 解决返回String乱码 */ @Override protected void configureMessageConverters(List<HttpMessageConverter> converters) { super.configureMessageConverters(converters); converters.add(responseBodyConverter()); } @Bean public HttpMessageConverter responseBodyConverter() { return new StringHttpMessageConverter(Charset.forName("UTF-8")); } @Override protected void addInterceptors(InterceptorRegistry registry) { super.addInterceptors(registry); registry.addInterceptor(localeChangeInterceptor); } }
三、测试
测试接口：
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; @RestController public class TestController { @GetMapping("/test") public String doTest() { return I18nUtils.getMessage("hello"); } }
