我在我的 spring 项目中配置了基于 cookie 的主题解析器和语言环境解析器。本地化在以下配置下正常工作。
<mvc:interceptors>
<ref bean="localeChangeInterceptor"/>
<ref bean="themeChangeInterceptor" />
</mvc:interceptors>
<bean id="localeChangeInterceptor" class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor">
<property name="paramName" value="language"/>
</bean>
<bean id="localeResolver" class="org.springframework.web.servlet.i18n.CookieLocaleResolver">
<property name="defaultLocale" value="en"/>
<property name="cookieName" value="locale"/>
<property name="cookieMaxAge" value="86400"/>
</bean>
<bean id="messageSource" class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
<property name="basenames">
<list>
<value>/WEB-INF/i18n/labels</value>
<value>/WEB-INF/i18n/messages</value>
</list>
</property>
<property name="defaultEncoding" value="UTF-8"/>
</bean>
我还使用以下配置配置了主题解析器。
<bean id="themeSource"
class="org.springframework.ui.context.support.ResourceBundleThemeSource">
<property name="basenamePrefix" value="resources.theme-"/>
</bean>
<bean id="themeChangeInterceptor"
class="org.springframework.web.servlet.theme.ThemeChangeInterceptor">
<property name="paramName" value="theme" />
</bean>
<bean id="themeResolver"
class="org.springframework.web.servlet.theme.CookieThemeResolver">
<property name="defaultThemeName" value="orange" />
<property name="cookieName" value="theme"/>
<property name="cookieMaxAge" value="86400"/>
</bean>
在我的 JSP 中，我使用以下代码行来加载正确的 CSS。
<link href='${pageContext.servletContext.contextPath}<spring:theme code="css_theme_style"/>' rel="stylesheet" type="text/css"/>
文件theme-orange的内容如下。
css_theme_style=/resources/template/template1/css/style.css
而且我无法在 themeResolver bean 中加载默认主题设置为橙色的主题。当我请求我的主页时，它会尝试使用语言环境 en 查找主题文件。但据我说，它不应该使用语言环境加载主题的属性文件。
我收到以下异常。

当我将配置更改为 SessionThemeResolver 时，一切正常。但我只想用 cookie 来做。
请帮我。提前致谢。
