SpringBoot配置拦截器,指定拦截或放行的请求路径

配置类:

@Configuration
public class AppConfig implements WebMvcConfigurer {

    @Bean
    public MyInterceptor myInterceptor() {
        return new MyInterceptor();
    }
    /**
     * 注册自定义拦截器
     * 指定要拦截的路径
     * /api/blog/** 拦截请求前缀为api/blog的请求,其他请求放行
     * /user/** 放行请求的路径
     */
    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(myInterceptor()).addPathPatterns("/api/blog/**").excludePathPatterns("/user/**");
    }
}

拦截器:

public class MyInterceptor implements HandlerInterceptor {
    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler){
    	return true;
    }
    @Override
    public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception {

        HandlerInterceptor.super.postHandle(request, response, handler, modelAndView);
    }

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

        HandlerInterceptor.super.afterCompletion(request, response, handler, ex);
    }
}
