Spring LocaleResolver 不要放到 startPage(http://localhost:8080/) defaultLocale

Question

大家好。

我配置了 LocaleResolver 来设置 defaultLocale，但它不适用于起始页（

  <welcome-file-list>
        <welcome-file>/WEB-INF/view/index.jsp</welcome-file>
    </welcome-file-list>

)。

web.xml：

   <?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"

            <param-value>/WEB-INF/config/mvc-config.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>dispatcher</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

    <welcome-file-list>
        <welcome-file>/WEB-INF/view/index.jsp</welcome-file>
    </welcome-file-list>

    <error-page>
        <error-code>404</error-code>
        <location>/WEB-INF/view/error/errorpage.jsp</location>
    </error-page>
    </web-app>

如果我将尝试直接访问http://localhost:8080/index.htlm - 它设置为默认区域设置。 对于 SessionLocaleResolver - 结果相同。

感谢您的关注。

Answer 1

像这样更新你的拦截器。

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

感谢先生。 M.德南。问题 -
不要使用欢迎页面，而是让 DispatcherServlet 提供所有页面。 另外可以使用：

 <mvc:view-controller path="/" view-name="first-view page"> 

谢谢大家。
