首先專案中已有如下配置：

頁面：

<form action="${base}/ztzx/lianHeChengJie" accept-charset="UTF-8" onsubmit="document.charset='UTF-8'">
</form>

<meta http-equiv="Content-Type" content="text/html;charset=utf-8">

web.xml

<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>

然後按照網上搜索提示新增如下：

但是依然亂碼

而後在server.xml中新增URIEncoding="UTF-8"

<Connector connectionTimeout="20000" port="8050" protocol="HTTP/1.1" redirectPort="8443" URIEncoding="UTF-8"/>

解決！
