SpringMVC_中文乱码的配置 --跟海涛学SpringMVC(和自己在项目中的实际使用的对比)

spring Web MVC框架提供了org.springframework.web.filter.CharacterEncodingFilter用于解决POST方式造成的中文乱码

<filter>
<filter-name>CharacterEncodingFilter</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>CharacterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

我的配置:

这个地方有一个问题,一般的小网站都有登陆过滤器,但是配置登陆过滤器的时候,会出现乱码,解决方案是

调整登陆过滤器和CharacterEncodingFilter的filter-mapping的顺序

 <filter>
    <filter-name>encodingFilter</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>encodingFilter</filter-name>
    <url-pattern>*.htm</url-pattern>
  </filter-mapping>

//先配置org.springframework.web.filter.CharacterEncodingFilter再配置自定义的filter
 <filter>
    <filter-name>loginFilter</filter-name>
    <filter-class>tss.kz.filters.LoginFilter</filter-class>
    <init-param>
      <param-name>indexPath</param-name>
      <param-value>index.htm</param-value>
    </init-param>
    <init-param>
      <param-name>ignoreList</param-name>
      <param-value></param-value>
    </init-param>
  </filter>

   <filter-mapping>
    <filter-name>loginFilter</filter-name>
    <url-pattern>*.htm</url-pattern>
  </filter-mapping>
