您可以尝试在 web.xml 中配置 org.apache.catalina.filters.SetCharacterEncodingFilter，如下所示:

<filter>
    <filter-name>Set Character Encoding</filter-name>
    <filter-class>org.apache.catalina.filters.SetCharacterEncodingFilter</filter-class>
    <init-param>
        <param-name>encoding</param-name>
        <param-value>UTF-8</param-value>
    </init-param>
    <init-param>
        <param-name>ignore</param-name>
        <param-value>false</param-value>
    </init-param>
</filter>
<filter-mapping>
    <filter-name>Set Character Encoding</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

Filter that sets the character encoding to be used in parsing the incoming request, either unconditionally or only if the client did not specify a character encoding.
