springboot国际化

1.添加国际化文件

2.application.properties中添加配置参数

spring.messages.basename=i18n.common,i18n.login

3.编写工具类I18nUtil

package com.example.demo;

import org.springframework.context.MessageSource;
import org.springframework.context.MessageSourceAware;
import org.springframework.stereotype.Component;
import org.springframework.util.ObjectUtils;

import java.util.Locale;

@Component
public class I18nUtil implements MessageSourceAware {

    private MessageSource messageSource;

    @Override
    public void setMessageSource(MessageSource messageSource) {
        this.messageSource = messageSource;
    }

    public String get(String key, String locale){
        Locale realLocale = Locale.getDefault();
        if(!ObjectUtils.isEmpty(locale)){
            switch (locale){
                case "US":
                    realLocale = Locale.US;
                    break;
                case "CN":
                    realLocale = Locale.CHINA;
                    break;
            }
        }
        return messageSource.getMessage(key, null, realLocale);
    }
}

4.测试controller

package com.example.demo;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("user")
public class UserController {

    @Autowired
    private I18nUtil i18nUtil;

    @RequestMapping("i18n")
    public String i18n(String key, String locale){
        return i18nUtil.get(key, locale);
    }
}

5.测试

http://localhost:8000/user/i18n?key=order.tip&locale=US

http://localhost:8000/user/i18n?key=order.tip&locale=CN

6.另外方式

package com.example.demo;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.ConfigurableApplicationContext;

import java.util.Locale;

@SpringBootApplication
@MapperScan("com.example.demo.test")
public class DemoApplication {

    public static void main(String[] args) {
        ConfigurableApplicationContext context = SpringApplication.run(DemoApplication.class, args);
        String message = context.getMessage("order.tip", null, Locale.US);
        System.out.println(message);
    }

}
