web.xml 設置字符編碼

 

個人理解  就是為了防止在前端輸入的數據到了后台發生亂碼

直接復制到web.xml里面就可以使用 親測 能用!!!

 

<!-- 前端過濾器設置字符編碼 -->
<filter>
<filter-name>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>encoding-filter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
