Spring-boot 多语言的处理

Spring-boot 实现多语言切换，很简单：

加入一个配置类就可以

package net.watermelon;

import java.util.Locale;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
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
@EnableAutoConfiguration
@ComponentScan
public class Application extends WebMvcConfigurerAdapter {
	public static void main(String[] args) {
		SpringApplication.run(Application.class, args);
	}

	@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());
	}
}

   在页面上，如下的切换方式：

        

    <a href="?lang=en_US" > 英语</a>
        <a href="?lang=zh_CN" > 中文</a>

   点击以后切换 缺省的语言。
