SpringBoot通过一个注解结合Redis实现接口限流就是这么简单( 二 ) _SpringBoot

<= 0) {response.setContentType("application/json;charset=utf-8") ;Map res = Map.ofEntries(Map.entry("code", -1),Map.entry("message", "访问太快了")) ;response.getWriter().println(new ObjectMapper().writeValueAsString(res)) ;return false ;} else {this.stringRedisTemplate.opsForValue().decrement(key) ;return true ;}}}}}return true ;}}

配置拦截器

@Componentpublic class AccessLimitConfig implements WebMvcConfigurer {@Resourceprivate AccessLimitInterceptor accessLimitInterceptor ;@Overridepublic void addInterceptors(InterceptorRegistry registry) {registry.addInterceptor(accessLimitInterceptor).addPathPatterns("/**")// 对登录和退出接口放行.excludePathPatterns("/login", "/logout") ;}}

以上就是核心类，整体还是非常简单的，主要判断都在拦截器中。接下来进行接口测试

@RestController@RequestMapping("/acc")public class AccessLimitController {@AccessLimit(seconds = 1, count = 2)@GetMapping("/index")public Object index() {return "success" ;}}
