中文乱码问题

①关于tomcat编码设置

    在tomcat的安装路径下找到conf目录下面的server.xml。找到<Connector  port="8080"   URLEncoding= "utf-8" useBodyEncodingForURI="true">

其中：URLEncoding="utf-8"表示对url只用utf-8进行处理。useBodyEncoding=“true”表示对post和get使用一种编码格式

<filter>

  <filter-name>encodingFilter</filter-name>

  <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>

  <init-param>

    <param-name>encoding</param-name>

  </init-param>

  <init-param>

    <param-name>forceEncoding</param-name>
