乱码有很多中原因
下面是其中一种解决办法，你可以试试

修改tomcat的conf/server.xml 

把 

<Connector port="8080" protocol="HTTP/1.1" 

               connectionTimeout="20000" 

               redirectPort="8443" /> 

改成 

<Connector port="8080" protocol="HTTP/1.1" 

               connectionTimeout="20000" 

               redirectPort="8443" 
URIEncoding="UTF-8"/>

如果还乱码，请在web.xml中添加一个过滤器

<filter>
    <filter-name>CharacterEncodingFilter</filter-name>
    <filter-class>com.worthtech.app.filter.CharacterEncodingFilter</filter-class>
    <init-param>
      <param-name>encoding</param-name>
      <param-value>UTF-8</param-value>
    </init-param>
    <init-param>
      <param-name>ignore</param-name>
      <param-value>true</param-value>
    </init-param>
  </filter>
  <filter-mapping>
    <filter-name>CharacterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>
