SpringBoot internationalization configuration, SpringBoot Locale internationalization
================================

1. The effect is as follows:
2. SpringBoot internationalization configuration
1. Create internationalization configuration files (3):
mess.properties
mess.user.name=Username mess.user.password=Password mess.user.btn=Login
mess_zh_CN.properties
mess.user.name=Username mess.user.password=Password mess.user.btn=Login
mess_en_US.properties
mess.user.name=UserName mess.user.password=Password mess.user.btn=Sign In
The default internationalization file of SpringBoot is: classpath:message.properties. If it is placed in another folder, you need to configure the property spring.messages.basename in application.properties:
# Indicates the i18n folder placed on the classpath, the file prefix is mess spring.messages.basename=i18n.mess
2. Custom internationalized language parser
import java.util.Locale;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
import org.springframework.web.servlet.LocaleResolver;
import org.thymeleaf.util.StringUtils;
/**
* Custom internationalized language parser
*
*/
public class MyLocaleResolver implements LocaleResolver{
private static final String I18N_LANGUAGE = "i18n_language";
private static final String I18N_LANGUAGE_SESSION = "i18n_language_session";
@Override
public Locale resolveLocale(HttpServletRequest req) {
String i18n_language = req.getParameter(I18N_LANGUAGE);
Locale locale = Locale.getDefault();
if(!StringUtils.isEmpty(i18n_language)) {
String[] language = i18n_language.split("_");
locale = new Locale(language[0], language[1]);
//将国际化语言保存到session
HttpSession session = req.getSession();
session.setAttribute(I18N_LANGUAGE_SESSION, locale);
}else {
//如果没有带国际化参数，则判断session有没有保存，有保存，则使用保存的，也就是之前设置的，避免之后的请求不带国际化参数造成语言显示不对
HttpSession session = req.getSession();
Locale localeInSession = (Locale) session.getAttribute(I18N_LANGUAGE_SESSION);
if(localeInSession != null) {
locale = localeInSession;
}
}
return locale;
}
@Override
public void setLocale(HttpServletRequest req, HttpServletResponse res, Locale locale) {
}
}
3、把国际化语言解析器放到Spring容器中：
这里创建了一个自定义的配置类：CustomMvcConfig ，继承WebMvcConfigurerAdapter，可以扩展SpringMvc的功能，包括拦截器，转换器等
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 com.lqy.springboot.message.locale.MyLocaleResolver;
//使用WebMvcConfigurerAdapter可以扩展SpringMvc的功能，包括拦截器，转换器等
//@EnableWebMvc //设置@EnableWebMvc为完全接管SpringMvc，但一般不要设置完全接管SpringMvc
@Configuration
public class CustomMvcConfig extends WebMvcConfigurerAdapter {
/**
* 配置自己的国际化语言解析器
* @return
*/
@Bean
public LocaleResolver localeResolver() {
return new MyLocaleResolver();
}
/**
* 配置自己的拦截器
*/
@Override
public void addInterceptors(InterceptorRegistry registry) {
//super.addInterceptors(registry);
}
}
4、页面显示及切换国际化操作：
<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
<style type="text/css">
.ib{
display: inline-block;
}
.ml20{
margin-left: 20px;
}
.mt20{
margin-top: 20px;
}
</style>
</head>
<body>
<div>
<div>[[#{mess.user.name}]]：<input th:placeholder="#{mess.user.name}"/></div>
</div>
<div>
<div>[[#{mess.user.password}]]：<input th:placeholder="#{mess.user.password}"/></div>
</div>
<div>
<div><button>[[#{mess.user.btn}]]</button></div>
</div>
<div class="mt20">
<span class="ib"><a th:href="@{/mess(i18n_language=zh_CN)}">中文</a></span>
<span class="ib ml20"><a th:href="@{/mess(i18n_language=en_US)}">英文</a></span>
</div>
</body>
</html>
