spring框架中遇到頁面上亂碼問題

1.web.xml中配置

<!--解決瀏覽器亂碼問題-->
<filter>
    <filter-name>characterEncodingFilter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <init-param>
        <param-name>encoding</param-name>
        <param-value>UTF-8</param-value>
    </init-param>
    <init-param>
        <param-name>forceEncoding</param-name>
        <param-value>true</param-value>
    </init-param>
</filter>

<filter-mapping>
    <filter-name>characterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

請注意上方配置的是 /*

2.如果上面的配置還不可以  在springmvc.xml文件中配置如下

<mvc:annotation-driven>
    <mvc:message-converters>
        <bean class="org.springframework.http.converter.StringHttpMessageConverter">
            <property name="supportedMediaTypes">
                <list>
                    <!--<span style="white-space:pre"></span>-->
                    <value>text/html;charset=UTF-8</value>
                    <value>application/json;charset=UTF-8</value>
                    <value>*/*;charset=UTF-8</value>
                </list>
            </property>
        </bean>
    </mvc:message-converters>
</mvc:annotation-driven>

/ 和 /*的區別
