Post乱码问题

spring提供编码过滤器

web.xml:

注意:要配置在拦截器前面

  <filter>

  <filter-name>characterEncodingfilter-name>

  <filter-class>org.springframework.web.filter.CharacterEncodingFilterfilter-class>

      <init-param>

          <param-name>encodingparam-name>

          <param-value>utf-8param-value>

      init-param>

  filter>

拦截所有

  <filter-mapping>

  <filter-name>characterEncodingfilter-name>

  <url-pattern>/*url-pattern>

  filter-mapping>
