无法使用弹簧执行器-创建bean CacheMetricsRegistrarConfiguration时出错

Question

最近，我添加了对org.springframework.boot:spring-boot-starter-actuator依赖，因为我想监视我的应用程序状态（如UP等），但是在应用程序启动时，我遇到了此异常。

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标头：

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

有人可以帮我吗？ 我正在运行2.0.1.RELEASE春季启动版本。 感谢您的任何帮助。

Answer 1

当前，Spring Boot Micrometer 需要使用net.sf.ehcache:ehcache:2.10.4 。 您在代码中使用了另一个Ehcache版本，该版本没有net.sf.ehcache.Ehcache.getStatistics()方法。

如果您打算使用Spring Boot Micrometer，请使用Ehcache 2.10.4或更高版本。
