我使用带有[spring-boot-legacy 1.1.0][1]的spring boot 1.4.2以部署到weblogic 10.3（java 6 / servlet 2.5）.....当我评论度量过滤器时，每个thins都在tomcat 7上工作正常part ...当我部署到weblogic时我只遇到问题....所以我回到tomcat以运行它...我取消注释度量过滤器，当我尝试部署我的应用程序时它给出：

我有这是我的build.gradle：
compile('org.springframework.boot:spring-boot-legacy:1.1.0.RELEASE')
这是MetricFilterAutoConfiguration项目中spring-boot-legacy的代码，其中定义了度量过滤器bean：

我还需要什么来避免此错误
答案 0 :(得分：0)
最有可能我发现了问题... tomcat 7实际上是servlet 3.0容器而不是servlet 2.5 ...因此@ConditionalOnMissingClass("javax.servlet.ServletRegistration")不满意，因为这个类在servlet 3.0中...所以bean没有创建...我正要检查tomcat 6 ...但没有时间
答案 1 :(得分：0)
根据我对spring documents的理解，“MetricFilterAutoConfiguration”类不包含在配置中，因为至少有一个条件注释不符合。
