ssm+thymeleaf国际化

一. 国际化项目结构和注意点

注意国际化文件必须在resource下,且文件后缀形如_zh_CN.properties这是springboot解析规范,当然本章讲解ssm国际化.springboot更为简单.

二.在xml配置类中配置相关国际化内容

xml引入识别国际化资源

    
    <bean id="messageSource"
          class="org.springframework.context.support.ResourceBundleMessageSource">
        
        <property name="basename" value="i18n.language" />
        <property name="useCodeAsDefaultMessage" value="true" />
        <property name="defaultEncoding" value="utf-8"/>
    bean>

    
    <mvc:interceptors>
        <bean id="localeChangeInterceptor"
              class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor">
            <property name="paramName" value="lang" />
        bean>
    mvc:interceptors>

三.国际化切换控制配置类

MyLocalResolver.java

@Configuration
public class MyLocalResolver implements LocaleResolver {

    @Override
    public Locale resolveLocale(HttpServletRequest httpServletRequest) {
        //获取区域的标识
        String flag = httpServletRequest.getParameter("flag");
        //获取默认区域对象
        Locale locale = Locale.getDefault();
        //判断区域标识是否为空
        if(flag != null){
            //对区域标识进行拆分处理
            String[] splits = flag.split("_");//使用下划线切分字符串返回一个字符串数组
            //利用区域标识创建区域对象
            locale = new Locale(splits[0],splits[1]);
        }
        return locale;
    }

    @Override
    public void setLocale(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Locale locale) {

    }
    @Bean
    public LocaleResolver localeResolver(){
        return new MyLocalResolver();
    }
}

MyLocalResolver配置类加了@Configuration注解,因此请求会被MyLocalResolver 处理切换语言
@{/}默认被解析跳转到login
