你可以尝试配置org.apache.catalina.filters.SetCharacterEncodingFilter您web.xml的未来：
<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>
设置用于解析传入请求的字符编码的过滤器，它是无条件的或仅在客户端未指定字符编码的情况下。
