Tomcat 设置URI默认字符集为UTF-8

新配置一个Spring的MVC项目。发现对Get请求的中文參数出现了乱码：

查看了SpingMVC中关于编码的配置(在web.xml中）。例如以下

    <filter>
        <filter-name>encodingFilter</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>encodingFilter</filter-name>
        <servlet-name>appkit</servlet-name>
    </filter-mapping>

应该不是Spring的问题，应该是Tomcat的问题，然后去改动Tomcat的配置文件server.xml，加入URIEncoding="UTF-8"

    <Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443"
               URIEncoding="UTF-8"/>

然后就好了
