我正在尝试使用Atlas配置千分尺。我正在遵循千分尺和Spring提供的指南(我使用的是Spring Boot 2.0.1(，我不明白是什么失败了。
我有以下配置：
public class AtlasMeterConfiguration {
@Bean
MeterRegistry meterRegistry() {
AtlasConfig atlasConfig = new AtlasConfig() {
@Override
public Duration step() {
return Duration.ofSeconds(10);
}
@Override
public String get(String k) {
return null; // accept the rest of the defaults
}
};
try(CompositeMeterRegistry compositeRegistry = new CompositeMeterRegistry();
SimpleMeterRegistry oneSimpleMeter = new SimpleMeterRegistry()) {
AtlasMeterRegistry atlasMeterRegistry = new AtlasMeterRegistry(atlasConfig, Clock.SYSTEM);
compositeRegistry.add(oneSimpleMeter);
compositeRegistry.add(atlasMeterRegistry);
return atlasMeterRegistry;
}
}
}
我将其添加到我的一个 REST 控制器中：
registry.timer("my.latency", "input").record(() -> {
registry.get("my.latency").counter().increment();
return registry.get("my.latency").counter();
});
和@Timed注释，但我得到的只是以下错误：

有人知道如何解决这个问题吗？
谢谢！
问题是我导入了micrometer-spring-legacy的依赖项，因为我阅读了 spring-boot 1.5.x 而不是 2.0.x 的指南。这就是为什么EmbeddedWebApplicationContext丢失的原因，在 2.0.x 中你没有它。
从 pom 中删除遗留的 jar 依赖项。
<dependency>
<groupId>io.micrometer</groupId>
<artifactId>micrometer-spring-legacy</artifactId>
<version>1.0.3</version>
</dependency>
