Micrometer(micrometerClock)中的错误处理条件
Error processing condition in Micrometer (micrometerClock)
我正在尝试使用 Atlas 配置 Micrometer。我正在按照 Micrometer 和 Spring 提供的指南进行操作（我正在使用 Spring Boot 2.0.1），但我不明白失败的原因。
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：

有人知道怎么解决吗？
谢谢！
问题是我正在导入 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 EmbeddedWebApplicationContext 丢失的原因，在 2.0.x 你没有。
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>
