配置tomcat7，避免403 Access Denied错误

在context.xml中改

<Context reloadable="true">

在server.xml改

    <Connector port="80" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" URIEncoding="UTF-8"/>

在tomcat-users.xml中改为

<tomcat-users>
  <role rolename="manager-gui"/>
  <role rolename="admin-gui"/>
  <user username="zby" password="tomcat" roles="manager-gui,admin-gui"/>
</tomcat-users>

华丽的分割线---------------------------------------------

如果角色不为：manager-gui,admin-gui就会出现403错误~
