java - 无法使用 Spring 执行器 - 创建 bean CacheMetricsRegistrarConfiguration 时出错

Question

最近我添加了对 org.springframework.boot:spring-boot-starter-actuator 的依赖项，因为我想监视我的应用程序状态，例如 UP 等。应用程序启动我收到此异常。

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.boot.actuate.autoconfigure.metrics.cache.CacheMetricsRegistrarConfiguration': Invocation of init method failed; nested exception is java.lang.NoSuchMethodError: net.sf.ehcache.Ehcache.getStatistics()Lnet/sf/ehcache/statistics/StatisticsGateway;

我正在使用这个 SpringBootApplication header :

@SpringBootApplication(exclude = {
        DataSourceAutoConfiguration.class, 
        WebMvcAutoConfiguration.class,
        HibernateJpaAutoConfiguration.class
})

有人可以帮我吗？我正在运行 2.0.1.RELEASE spring boot 版本。感谢您的帮助。

当前 Spring Boot 千分尺 requires net.sf.ehcache:ehcache:2.10.4 。您在代码中使用了不同的 Ehcache 版本，该版本没有 net.sf.ehcache.Ehcache.getStatistics() 方法。

如果您计划使用 Spring Boot Micrometer，请使用 Ehcache 2.10.4 或更高版本。
