框架中拦截器解决乱码问题。

解决中文乱码问题

思路1: 自己配置过滤器

步骤: (1) 开发一个Filter

(2) 在web.xml中配置过滤器

<!– 配置自己写的过滤器 –>

<filter>

<filter-name>MyFilter</filter-name>

<filter-class>com.hsp.web.filter.MyFilter</filter-class>

</filter>

<filter-mapping>

<filter-name>MyFilter</filter-name>

<url-pattern>/*</url-pattern>

</filter-mapping>

思路2：使用spring框架提供的处理中文乱码的过滤器，同样配置在web.xml

<filter>

      <filter-name>encoding</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>

</filter>

<filter-mapping>

      <filter-name>encoding</filter-name>

      <url-pattern>/*</url-pattern>

</filter-mapping>
