Java NoSuchBeanDefinitionException：没有名为'；metricFilter'；可获得的

为了部署到weblogic 10.3（java 6/servlet 2.5）…当我评论度量过滤器部分时，我正在使用spring boot 1.4.2和

[spring boot legacy 1.1.0][1]

。。。我只有在部署到weblogic时才会遇到问题。。。。所以我回到tomcat来运行它。。。当我尝试部署我的应用程序时，我取消了度量过滤器的注释：

我还需要什么来避免这个错误呢

很可能我已经解决了这个问题。。。Tomcat7实际上是Servlet3.0容器，而不是Servlet2.5。。。因此，

@ConditionalOnMissingClass（“javax.servlet.ServletRegistration”）

不满足，因为Servlet3.0中有这个类。。。所以这个bean不是被创建的。。。我正要检查tomcat 6。。。但是没有时间

根据我的理解，“MetricFilterAutoConfiguration”类未包含在配置中，这是因为至少有一个条件批注未满足。

您确定您的应用程序上下文中有“metricFilter”bean吗？@ali4j。。请检查我添加到问题中的

MetricFilterAutoConfiguration

代码，我建议您在

return new MetricsFilter（）行中插入断点@ConditionalOnBean（{CounterService.class，GaugeService.class}）@ConditionalOnClass（{Servlet.class，MetricRepositoryAutoConfiguration.class}）@ConditionalOnMissingClass(“javax.servlet.ServletRegistration”）“

未满足条件。

MetricRepositoryAutoConfiguration

位于

spring boot legacy

jar中，不在spring core中。。。我在问题中包含了它的代码。我的意思是，在这个配置类[MetricFilterAutoConfiguration]中声明的那些bean没有包含在上下文中，因此您得到的是“NoSuchBeanDefinitionException”异常。
