i18消息属性不通过Controller反映在JSP中

Question

感谢任何帮助，因为我在将这些内容放在一起时迷失了，并且JSP不会根据URL参数中传递的语言显示spring消息。当在welcome.jsp中选择了不同的语言时，JSP没有通过SessionLocaleResolver获取SessionLocale。我在做什么/出错了什么。

我正在使用Spring 3.1.1。提前致谢

我的WelcomeController

@Controller
public class WelcomeController {

@Autowired
private MessageSource messageSource;

public void setMessageSource(MessageSource messageSource) {
    this.messageSource = messageSource;
}

@RequestMapping(value = "/welcome", method = RequestMethod.GET)
public String welcome(Model model, HttpServletRequest request, HttpServletResponse response) {
    String lang = request.getParameter("lang");
    if (lang == null) {
        lang = "en_US";
    }
    /**
     * Get Message having PARAMETERS in the message {0}, {1}.....{n}
     */
    model.addAttribute(
            "welcome_back_msg",
                messageSource.getMessage("message_welcome_back_user", new Object[] { "(USER)",
                        new DateTime(), new DateTime() }, new Locale(lang)));
    return "welcome";
}
}

消息文件放在/ WEB-INF / messages /中 messages_en.properties

welcome_springmvc=Welcome to Spring MVC
message_welcome_back_user=Welcome back {0} Your Last Successful : {1} Failed : {2}

messages_zh.properties

welcome_springmvc=\u6B22\u8FCE\u5230 Spring \u7684 MVC

message_welcome_back_user = \ u6B22 \ u8FCE \ u56DE \ u6765 {0} \ u4E0A \ u6B21 \ u6210 \ u529F：{1} \ u5931 \ u8D25：{2}

messages_fr.properties

welcome_springmvc=Bienvenue \u00E0 Spring MVC

message_welcome_back_user = Bienvenue \ u00E0 nouveau {0} Votre r \ u00E9ussite Derni \ u00E8re：{1} manqu \ u00E9：{2}

--- welcome.jsp

Spring Message from Property:<b><spring:message code="welcome_springmvc" text="default text" /></b>
Message from Controller:<b>${welcome_back_msg}

您可以看到来自Property的Spring Message总是回退到locale = en。 感谢这方面的任何帮助。

仅仅实例化LocaleChangeInterceptor Bean是不够的。除了所有拦截器，它必须注册为拦截器：

所以把bean def放在<mvc:interceptors>标签中：

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

顺便说一句：看一下jsp spring消息标记
