2.java读取
/**
*serviceName
*serviceName2 文件路径名称
*paramName
*/
 public String getServiceParam(String serviceName, String serviceName2, String paramName) throws MetaException
   {
    EntryObject topEntry = getTopEntry();
    EntryObject servEntry = topEntry.getChildEntry(serviceName);
    EntryObject servEntry2 = servEntry.getChildEntry(serviceName2);
     if (servEntry == null) {
      throw new MetaFindException(serviceName + " is not found as a service meta entry");
    }
    if (servEntry2 == null) {
       return getServiceParam(serviceName, paramName);
    }
    return servEntry2.getValue(paramName);
   }
}
 
3.调用
   String connUrl = SysInfoReader.instance().getServiceParam("db_pool", "default", "poolurl");
    String dbDrv = SysInfoReader.instance().getServiceParam("db_pool", "default", "driver");
    String dbLogin = SysInfoReader.instance().getServiceParam("db_pool", "default", "login");
    String dbPw = SysInfoReader.instance().getServiceParam("db_pool", "default", "password");
