Question

我正在尝试这个dispacther servlet xml文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd"
       xmlns:p="http://www.springframework.org/schema/p">
    <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix">
            <value>/WEB-INF/jsp/</value>
        </property>
        <property name="suffix">
            <value>.jsp</value>
        </property>
    </bean>
    <bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
        <property name="interceptors">
            <list>
                <ref local="localeChangeInterceptor"/>
            </list>
        </property>
        <property name="urlMap">
            <map>
                <entry key="/hello.html">
                    <ref bean="helloController"/>
                </entry>
            </map>
        </property>
    </bean>
    <bean id="helloController" class="net.roseindia.web.HelloWorldController"></bean>
    <bean id="localeChangeInterceptor" class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor">
        <property name="paramName" value="hl"/>
    </bean>
    <bean id="localeResolver" class="org.springframework.web.servlet.i18n.SessionLocaleResolver"/>
</beans>

我无法理解像

这样的事情

<property name="interceptors">
    <list>
        <ref local="localeChangeInterceptor"/>
    </list>
</property>

拦截器的功能是什么，localeChangeInterceptor是什么？这个区域解析器也是什么？

<bean id="localeResolver" class="org.springframework.web.servlet.i18n.SessionLocaleResolver"/>

Answer 1

Spring Reference中描述了这些组件的功能，请参阅15.6 Using locales。

LocaleResolver确定用户区域设置
LocaleChangeInterceptor允许用户手动更改其区域设置

需要一些dispatcher-servlet xml文件的帮助
