Spring在web请求中定义编码

Posted 2020-06-18 住家阿呆

最近有几个小伙伴在开发的时候竟然还出现了乱码情况，检查了下，竟然没写filter-mapping，记录下

通过类org.springframework.web.filter.CharacterEncodingFilter，操作web.xml

<filter>
  <filter-name>Spring character encoding filter</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>Spring character encoding filter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>
