1.在resources目录下添加三个国际化配置文件
message = 欢迎使用国际化（默认）
- messages_en_US.properties
message = Welcome to internationalization (English)
name = Lebron James
- messages_zh_CN.properties
message = \u6b22\u8fce\u4f7f\u7528\u56fd\u9645\u5316\uff08\u4e2d\u6587\uff09
name = \u52d2\u5e03\u6717\u002a\u8a79\u59c6\u65af
2.I18Config配置类
import java.util.Locale;
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;
/**
* @author haopeng
*/
@Configuration
@EnableAutoConfiguration
@ComponentScan
public class I18Config extends WebMvcConfigurerAdapter{
@Bean
public LocaleResolver localeResolver() {
SessionLocaleResolver slr = new SessionLocaleResolver();
// 默认语言
slr.setDefaultLocale(Locale.SIMPLIFIED_CHINESE);
return slr;
}
@Bean
public LocaleChangeInterceptor localeChangeInterceptor() {
LocaleChangeInterceptor lci = new LocaleChangeInterceptor();
// 参数名
lci.setParamName("lang");
return lci;
}
@Override
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(localeChangeInterceptor());
}
}
3.页面
<!--这里通过thymeleaf文字国际化表达式获取信息-->
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.w3.org/1999/xhtml">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<a href="/?lang=en_US">English(US)</a>
<a href="/?lang=zh_CN">简体中文</a></br>
<p><label th:text="#{message}"></label></p>
<p><label th:text="#{name}"></label></p>
</body>
</html>
4.项目配置
##端口号
server.port=8888
##去除thymeleaf的html严格校验
spring.thymeleaf.mode=LEGACYHTML5
#设定thymeleaf文件路径
spring.freemarker.template-loader-path=classpath:/templates
5.Controller
@Controller
public class IndexController {
@Autowired
private MessageSource messageSource;
@RequestMapping("/")
public String hello(Model model){
Locale locale = LocaleContextHolder.getLocale();
boolean isUs = locale.equals(Locale.US);
return "index";
}
}
6.补充
