SpringBoot_使用拦截器

@Component
public class MyInterceptor implements HandlerInterceptor {
    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        System.out.println("preHandle method is running!");
        return true;
    }

    @Override
    public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception {
        System.out.println("postHandle method is running!");
    }

    @Override
    public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception {
        System.out.println("afterCompletion method is running!");
    }
}

@Configuration
public class MvcConfiguration implements WebMvcConfigurer {

    @Autowired
    private HandlerInterceptor myInterceptor;

    /**
     * 重写接口中的addInterceptors方法，添加自定义拦截器
     * @param registry
     */
    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(myInterceptor).addPathPatterns("/**");
    }
}

preHandle method is running!
postHandle method is running!
afterCompletion method is running!
