前端GET请求乱码

前端get请求时会默认编码，导致后台取数据乱码，解决方案除了在web.xml里面加filter 过滤外，还要在tomcat 配置文件server.xml里面设置 Connector的URIEconding=“UTF-8"。

我的项目是spring项目，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"/>
