1.创建拦截器
@Slf4j
@Component
public class MyInterceptor implements HandlerInterceptor {
@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
log.info("MyInterceptor>>>preHandle");
return true;
}
@Override
public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception {
log.info("MyInterceptor>>>postHandle");
}
@Override
public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception {
log.info("MyInterceptor>>>afterCompletion");
}
}
2.注册拦截器
@Configuration
public class MyWebMvcConfig implements WebMvcConfigurer {
@Autowired
private MyInterceptor myInterceptor;
/**
* 配置自定义拦截器
*
* @param registry 注册器
*/
@Override
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(myInterceptor)
.addPathPatterns("/**")
.excludePathPatterns("/hello");
}
}
addPathPatterns表示拦截路径，excludePathPatterns表示排除的路径
