Springboot 實現國際化

1.首先配置application.properties

spring.messages.basename=static/i18n/messages
spring.messages.encoding=utf-8

2.通過全局配置加載國際化的bean對象

import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.LocaleResolver;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
import org.springframework.web.servlet.i18n.LocaleChangeInterceptor;
import org.springframework.web.servlet.i18n.SessionLocaleResolver;

import java.util.Locale;


/**

@Configuration
public class I18nConfig {
    @Value(value = "${spring.messages.basename}")
    private String basename;
    /**
     * 設置默認支持語言
     * @return
     */
    @Bean
    public LocaleResolver localeResolver(){
        SessionLocaleResolver sessionLocaleResolver = new SessionLocaleResolver();
        //設置默認的語言
        sessionLocaleResolver.setDefaultLocale(Locale.CHINA);
        return sessionLocaleResolver;
    }


    @Bean
    public WebMvcConfigurer localeInterceptor(){
        return new WebMvcConfigurer() {
            @Override
            public void addInterceptors(InterceptorRegistry registry) {
                LocaleChangeInterceptor localeChangeInterceptor = new LocaleChangeInterceptor();
                //通過請求參數 ?lang=cn_ZH 方式獲取具體的語言
                localeChangeInterceptor.setParamName("lang");
                registry.addInterceptor(localeChangeInterceptor);
            }
        };
    }
}

3.增加配置文件其中

   ************messages.properties是必須存在的無論有沒有數據

************Resource Bundle “messages”是自動創建的不需要管理

************m不同的語言通過不同的文件名結尾

4.我們可以通過MessageSource來獲取我們的國際化信息

@Autowired
    private MessageSource messageSource;


messageSource.getMessage(msgKey, null, LocaleContextHolder.getLocale());
