前端get請(qǐng)求時(shí)會(huì)默認(rèn)編碼，導(dǎo)致后臺(tái)取數(shù)據(jù)亂碼，解決方案除了在web.xml里面加filter 過濾外，還要在tomcat 配置文件server.xml里面設(shè)置 Connector的URIEconding=“UTF-8"。

我的項(xiàng)目是spring項(xiàng)目，web.xml配置如下：

 <filter>
  <filter-name>encodingFilter</filter-name>
  <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filte-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>
  <url-pattern>/*</url-pattern>
</filter-mapping>

server.xml配置

  <Connector port="8081" protocol="HTTP/1.1"
           connectionTimeout="20000"
           redirectPort="8443" URIEncoding="UTF-8"/>
