Spring Boot 配置拦截器

定义拦截器

public class MyInterceptor implements HandlerInterceptor {

    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) {
        return false;
    }

    @Override
    public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) {

    }

    @Override
    public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) {

    }
  
}

配置拦截器

注意，要让配置能被Spring扫描到

@Configuration
public class InterceptorConfig implements WebMvcConfigurer {
  
    @Bean
    MyInterceptor myInterceptor(){
        return new MyInterceptor();
    }

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(myInterceptor())
          .addPathPatterns("/**")
          .excludePathPatterns("/static");
    }

}
