设置tomcat字符煸码为utf-8

  设置tomcat的编码格式。把以下内容放到你的web.xml中。

    <mime-mapping>     
      <extension>htm</extension>     
      <mime-type>text/html;charset=utf-8</mime-type>     
    </mime-mapping>     
    <mime-mapping>   
      <extension>html</extension>     
      <mime-type>text/html;charset=utf-8</mime-type>     
    </mime-mapping>     
    <mime-mapping>   
      <extension>jsp</extension>     
      <mime-type>text/html;charset=utf-8</mime-type>     
    </mime-mapping>
    <mime-mapping>   
      <extension>action</extension>     
      <mime-type>text/html;charset=utf-8</mime-type>     
    </mime-mapping>

还可以用以下方法

    <jsp-config>
       <jsp-property-group>
          <description>test encode</description>
          <display-name>test encode</display-name>
          <url-pattern>/*</url-pattern>
          <page-encoding>utf-8</page-encoding>
       </jsp-property-group>
    </jsp-config>
