java - How to count number of requests in spring boot app?

Question

I have a spring boot application whose metrics I want to later send to gcp. But for now I just need to find a way to count the total number of requests my application is handling either with actuator or with micrometer. Does anybody know how I could do something like this? Thanks In advance

Answer 1

一个spring-actuator例子：

//add pom
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-actuator</artifactId>
</dependency>

使用执行器

@Bean
public SecurityWebFilterChain securityWebFilterChain(
  ServerHttpSecurity http) {
    return http.authorizeExchange()
      .pathMatchers("/actuator/**").permitAll()
      .anyExchange().authenticated()
      .and().build();
}

然后可以从http://localhost:8080/metrics获取数据

看看Spring Boot Actuator - HttpTrace

默认情况下，最新版本未启用它，但您可以通过实现HttpTraceRepository.

在此存储库中，您可以使用计数器来测量请求的数量，然后将其添加到 MetricRegistry。另一种选择是使用过滤器，然后在那里使用计数器。
