  • Interceptors in Spring allow you to intercept HTTP requests and responses
  • Step

    • Create a class which implement the HandlerInterceptor interface

      @Component
public class MyInterceptor implements HandlerInterceptor {

    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        System.out.println("PreHandle method is Calling");
        return true;
    }
}

    • Register the interceptor with Spring’s InterceptorRegistry

      @Configuration
public class WebConfig implements WebMvcConfigurer {

    @Autowired
    private MyInterceptor myInterceptor;

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