Internationalization of the SPRINGMVC Learning Series (8)

I. Internationalization implementations based on browser requests:

1) Add in spring's configuration file

<bean id= "Messagesource" class= "Org.springframework.context.support.ResourceBundleMessageSource" >    < !--internationalization information is in the file name--                         <property name= "basename" value= "Locale/message"/>       <!-- If you cannot find the corresponding code in the Internationalized resource file, use this code as the name---                   <property name= "Usecodeasdefaultmessage" value= "true"/>           </bean>

2) Create a folder locale under Resources, add Messages.properties, Messages_zh_cn.properties, messages_en_us.properties three files under locale

Like the content under Resources/locale/messages_zh_cn.properties.

Message.login.fail= Login failed message.login.success= Login succeeded

Like the content under Resources/locale/messages_en_us.properties.

Message.login.fail=login Failmessage.login.success=login Success

3) Read the contents of the resource file in the background and return to the foreground

Add a method to the controller file

    @RequestMapping (value = "/testmessage.do") public    String testMessage (httpservletrequest request,model Model)    {        logger.debug ("Enter Maincontroller.testmessage ()");                Get internationalized information from background code        RequestContext requestcontext = new RequestContext (request);        Model.addattribute ("Message", Requestcontext.getmessage ("message.login.success"));        return "Testmessage";    }

4) Front desk display

<%@ page language= "java" contenttype= "text/html; Charset=utf-8 "    pageencoding=" UTF-8 "%><! DOCTYPE HTML PUBLIC "-//w3c//dtd HTML 4.01 transitional//en" HTTP://WWW.W3.ORG/TR/HTML4/LOOSE.DTD "><% @taglib Prefix= "Spring" uri= "http://www.springframework.org/tags"%>
Display the contents of internationalized files directly in the foreground
<spring:message code= "Message.login.fail" ></spring:message></body>
　　
Two. Session-based internationalization implementation:
1) Add in spring's configuration file
<mvc:interceptors>      <!--international operation interceptors if you are using (Request/session/cookie), you must configure--     <bean class= " Org.springframework.web.servlet.i18n.LocaleChangeInterceptor "/>  </mvc:interceptors>  <bean Id= "Localeresolver" class= "Org.springframework.web.servlet.i18n.SessionLocaleResolver"/>
2) in the background
@RequestMapping (value = "/sessiontest", method = {Requestmethod.get})
Public String seesiontest (HttpServletRequest request, model model,
@RequestParam (value = "Langtype", defaultvalue = "zh") String Langtype)
{

if (Langtype.equals ("zh"))
{
Locale locale = new locale ("zh", "CN");
Request.getsession (). SetAttribute (Sessionlocaleresolver.locale_session_attribute_name, LOCALE);
}
else if (langtype.equals ("en"))
{
Locale locale = new locale ("en", "US");
Request.getsession (). SetAttribute (Sessionlocaleresolver.locale_session_attribute_name, LOCALE);
}
Else
Request.getsession (). SetAttribute (Sessionlocaleresolver.locale_session_attribute_name,
Localecontextholder.getlocale ());

Get internationalized information from background code
RequestContext RequestContext = new RequestContext (request);
Model.addattribute ("Message", Requestcontext.getmessage ("message.login.success"));
return "Testmessage";
}
3) Ibid.
4) on the JSP page, add
Use session Toggle <a href= "${ctx}/sessiontest?langtype=zh" > Chinese </a> | <a href= "${ctx}/sessiontest?langtype=en" > English </a><br/>
${message}<br>
Three. The internationalization of cookies-based implementations:
Similar to session, does not exist with the session mode
1) Add in spring's configuration file
<bean id= "Localeresolver" class= "Org.springframework.web.servlet.i18n.CookieLocaleResolver"/>
2) Backstage
 @RequestMapping (value = "/CookieTest", method = {Requestmethod.get}) public String CookieTest (httpservletrequest request, httpservletresponse response, model, @RequestParam (value = "lan GType ", defaultvalue =" zh ") String Langtype) {if (Langtype.equals (" zh ")) {locale locale = n            EW Locale ("zh", "CN");        (New Cookielocaleresolver ()). SetLocale (Request, response, locale);            } else if (Langtype.equals ("en")) {locale locale = new locale ("en", "US");        (New Cookielocaleresolver ()). SetLocale (Request, response, locale);                } else (new Cookielocaleresolver ()). SetLocale (Request, Response, Localecontextholder.getlocale ());        Get internationalized information from background code requestcontext RequestContext = new RequestContext (request);        Model.addattribute ("Message", Requestcontext.getmessage ("message.login.success"));    return "Testmessage"; }
　
3) Ibid.
4) on the JSP page, add
Use cookies to switch <a href= "${ctx}/cookietest?langtype=zh" > Chinese </a> | <a href= "${ctx}/cookietest?langtype=en" > English </a><br/>
${message}<br>
Four. Implementation of internationalization based on URL request:
1) Customizing a class
Import Java.util.locale;import Javax.servlet.http.httpservletrequest;import Javax.servlet.http.httpservletresponse;import Org.springframework.web.servlet.dispatcherservlet;import Org.springframework.web.servlet.localeresolver;public class Myacceptheaderlocaleresolver extends Acceptheaderlocaleresolver {    private Locale mylocal;    Public Locale Resolvelocale (HttpServletRequest request) {        return mylocal;    }     public void SetLocale (HttpServletRequest request, httpservletresponse response, locale locale) {        mylocal = locale;< c6/>}  }
2) Add in spring's configuration file
<bean id= "Localeresolver" class= "Xx.xxx.xxx.MyAcceptHeaderLocaleResolver"/>
"Xx.xxx.xxx" is the package name of the Myacceptheaderlocaleresolver class you just added.
After saving, you can attach LOCALE=ZH_CN or locale=en_us after the requested URL.
