Spring i18n国际化

从源码MessageSource的三个实现出发实战spring·i18n国际化 - 简熵 - 博客园

java 复制代码

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.MessageSource;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;
import org.springframework.context.annotation.Bean;
import org.springframework.context.support.ReloadableResourceBundleMessageSource;

import java.util.Locale;
import java.util.ResourceBundle;

@SpringBootApplication
public class HelloWorldSpringbootApplication {
    // ReloadableResourceBundleMessageSource可以加载指定项目以外的国际化文件
    private static String zhPath =
            "file:D:/temp/content";
    public static void main(String[] args) {
        // SpringApplication.run(HelloWorldSpringbootApplication.class, args);
        getSpringContent();
    }

    @Bean
    public ReloadableResourceBundleMessageSource messageSource() {
        ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();
        messageSource.setBasenames(zhPath, "classpath:content");
        return messageSource;
    }

    public static void getSpringContent() {
        AnnotationConfigApplicationContext ctx =
                new AnnotationConfigApplicationContext(HelloWorldSpringbootApplication.class);
        MessageSource source = ctx.getBean(MessageSource.class);
        Locale localeZh = new Locale("zh","CN");
        String hello = source.getMessage("hello", null, localeZh);
        System.out.println("hello = " + hello);
    }

    public static void getContent() {
        Locale localeEn = new Locale("en","US");
        Locale localeZh = new Locale("zh","CN");
        ResourceBundle res = ResourceBundle.getBundle("content", localeZh);
        String hello = res.getString("hello");
        System.out.println("hello = " + hello);
    }
}

再加三个文件：

复制代码

content.properties

java 复制代码

hello=123

复制代码

content_en_US.properties

java 复制代码

hello=hello_world

content_zh_CN.properties

java 复制代码

hello=456
