springMVC internationalization

SpringMVC 4.0 Internationalization

 

First, the configuration file of spring:

<!--Change the locale using the parameter passed the day before...?locale=zh_CN -->
    <mvc:interceptors >
        <bean class = "org.springframework.web.servlet.i18n.LocaleChangeInterceptor"/>
    </mvc:interceptors >

    <!--Configure the language conversion level, there is AcceptHeaderLocaleResolver: judged by the accept-language field of the http header;
        SessionLocaleResolver: Set the language during this session, and use this setting uniformly during the login cycle;
        CookieLocaleResolver: The previous language setting parameters are kept in the cookie, and are set according to the cookie each time;
        FixedLocaleResolver: Always use a fixed locale -->
    <bean id = "localeResolver" class = "org.springframework.web.servlet.i18n.CookieLocaleResolver" ></bean>

    <!-- When using ResourceBundleMessageSource for internationalization, the bean id must use messageSource-->
    <bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource">
        <property name="basenames" value="i18n.language"></property>
        <property name="cacheSeconds" value="-1"/>
    </bean>

 

Second, the JSP page

<h1 align="center">${message}</h1>
    <spring:message code="hello.prompt"></spring:message> ${language}<br/>
    <a href="/demo/language/test/chinese?locale=zh_CN"> 中文简体</a>|
    <a href="/demo/language/test/english?locale=en_US">English</a>|
    <a href="/demo/language/test/chineseTranditional?locale=zh_TW"> 中文繁體</a>
    <p style="font-size: medium;align-content: center">
        <spring:message code="hello.title"></spring:message>
    </p>

 

3. Background controller

@Controller
@RequestMapping("/language")
public class LanguageController {

    @RequestMapping("/test/{lan}")
    public String change (athPathVariable String lan, ModelMap modelMap)
        modelMap.put("language",lan);
        return "hello";
    }
}

 

4. Common mistakes

javax.servlet.jsp.JspTagException: No message found under code 'hello.prompt' for locale 'zh_TW' 试着将<bean id="messageResource" class="org.springframework.context.support.ReloadableResourceBundleMessageSource">改为<bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource">
