【Spring Boot】--拦截器配置

实现HandlerInterceptor接口

/**

 * @Date: 2018-12-03 19:09
 * @Description:
 */
@Slf4j
public class AuthInterceptor implements HandlerInterceptor {

    /**
     * 预处理方法，在调用控制器方法以前调用
     * @param request
     * @param response
     * @param handler
     * @return
     * @throws Exception
     */
    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response,
                             Object handler) throws Exception {
        log.info("preHandle is run...");
        return true;
    }

    /**
     * 处理后方法，在调用控制器方法以后调用
     * @param request
     * @param response
     * @param handler
     * @param modelAndView
     * @throws Exception
     */
    @Override
    public void postHandle(HttpServletRequest request, HttpServletResponse response,
                      Object handler, @Nullable ModelAndView modelAndView) throws Exception {
        log.info("postHandle is run...");
    }

    /**
     * 整个请求处理完毕调用
     * @param request
     * @param response
     * @param handler
     * @param ex
     * @throws Exception
     */
    @Override
    public void afterCompletion(HttpServletRequest request, HttpServletResponse response,
                                Object handler, @Nullable Exception ex) throws Exception {
        log.info("afterCompletion is run...");
    }

}

实现WebMvcConfigurer接口

/**
 * @Auther: chisj chisj@foxmal.com
 * @Date: 2018-12-03 19:02
 * @Description:
 */
@Configuration
public class WebMvcConfig implements WebMvcConfigurer {

    @Bean
    public AuthInterceptor authInterceptor() {
        return new AuthInterceptor();
    }


    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        // 添加拦截器
        registry.addInterceptor(authInterceptor()).addPathPatterns("/**");
    }

}
