Spring Boot实践--实现国际化

Spring boot 实现国际化

1：添加配置类

import java.util.Locale;

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.WebMvcConfigurerAdapter;
import org.springframework.web.servlet.i18n.LocaleChangeInterceptor;
import org.springframework.web.servlet.i18n.SessionLocaleResolver;

@Configuration
public class I18nConfig extends WebMvcConfigurerAdapter {
     @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());  
        }  

}

2：添加资源文件
默认读取路径在resources下：
可在application.properties中添加属性设置：

#i18n configuation
spring.messages.basename=i18n/messages

效果如下图：
这里写图片描述

messages.properties是默认访问资源

3：网页切换语言
于url上拼接属性如下

?lang=en_US

该属性会存于cookie中，网页跳转将继续使用该语言：

Cookie:JSESSIONID=9EFE46F94D0F89A9E7FBD1073631DEC5; hudson_auto_refresh=false; ACEGI_SECURITY_HASHED_REMEMBER_ME_COOKIE=d3A3NzE5MTAwMTI6MTQ4MjczNzMxNjkxMjpkZDQ2MzM2NTc3ZmM3ZjU1Y2UzYjk2YWU2NjkwNjlmMjNmMjQwMDhhZmRlOGQxOWQ0YzRjOTM4ZTAwNzYwZmM5; jenkins-timestamper-offset=-28800000; org.springframework.web.servlet.i18n.CookieLocaleResolver.LOCALE=en_US

最后一行即为存于cookie中的语言属性

4:controller层中语言属性

LocaleContextHolder.getLocale()

可获取Locale类
可用如下代码进行语言判断：

LocaleContextHolder.getLocale().equals(Locale.US)
