一、拦截器
public class SysInteceptor implements HandlerInterceptor {
/**
* 最后执行,可用于释放资源
*/
@Override
public void afterCompletion(HttpServletRequest arg0,
HttpServletResponse arg1, Object arg2, Exception arg3)
throws Exception {
// TODO Auto-generated method stub
}
/**
* 生成视图之前执行
*/
@Override
public void postHandle(HttpServletRequest arg0, HttpServletResponse arg1,
Object arg2, ModelAndView arg3) throws Exception {
// TODO Auto-generated method stub
}
/**
* Action之前执行
*/
@Override
public boolean preHandle(HttpServletRequest arg0, HttpServletResponse arg1,
Object arg2) throws Exception {
// TODO Auto-generated method stub
return true;
}
}
