1、LoginInterceptor拦截器
public class LoginInterceptor implements HandlerInterceptor {
private static final Logger log = LoggerFactory.getLogger(LoginInterceptor.class);
/**
* 进入controller层之前拦截请求
* @param httpServletRequest
* @param httpServletResponse
* @param o
* @return
* @throws Exception
*/
@Override
public boolean preHandle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o) throws Exception {
log.info("---------------------开始进入请求地址拦截----------------------------");
return true;
}
@Override
public void postHandle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, ModelAndView modelAndView) throws Exception {
log.info("--------------处理请求完成后视图渲染之前的处理操作---------------");
}
@Override
public void afterCompletion(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, Exception e) throws Exception {
log.info("---------------视图渲染之后的操作-------------------------0");
}
}
2、接下来我们需要将LoginInterceptor拦截器添加到SpringBoot的配置中，让SpringBoot项目有这么一个拦截器存在，我们新创建一个WebAppConfig，将拦截器的配置以及拦截路径配置好
