ssm 乱码

1、post乱码：在web.xml中增加解决解决post乱码的过滤器

  <!--解决POST乱码问题-->
  <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>

2、get 请求乱码：

<Connector URIEncoding="utf-8" port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443"/>

或者在方法里面处理：

new String(param..getBytes("iso8859-1"),"utf-8");
