一、效果所下:
二、SpringBoot 国际化配置
1、创建国际化配置文件(3个):
mess.properties
- mess.user.name=用户名
- mess.user.password=密码
- mess.user.btn=登录
mess_zh_CN.properties
- mess.user.name=用户名
- mess.user.password=密码
- mess.user.btn=登录
mess_en_US.properties
- mess.user.name=UserName
- mess.user.password=Password
- mess.user.btn=Sign In
SpringBoot默认国际化文件为:classpath:message.properties,如果放在其它文件夹中,则需要在application.properties配置属性spring.messages.basename:
- #表示放在classpath的i18n文件夹,文件前缀为mess
- spring.messages.basename=i18n.mess
2、自定义国际化语言解析器
- 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;
- /**
- * 自定义国际化语言解析器
- *
- */
- 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>
