Bean实例化报错org.springframework.beans.factory.BeanCreationException

近日在使用Spring boot 2.0.0.RELEASE 运行时，抛出了bean注入异常

代码如下:

@Bean
public FilterRegistrationBean httpFilter(){
   FilterRegistrationBean registrationBean = new FilterRegistrationBean();
   registrationBean.setFilter(new HttpFilter());
   registrationBean.addUrlPatterns("/threadLocal/*");
   return registrationBean;
}

报错信息大致如下：

2018-03-31 14:00:30.356 ERROR 18536 — [           main] o.s.boot.SpringApplication               : Application run failed

org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘httpFilter’ defined in com.mmall.concurrency.ConcurrencyApplication: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.boot.web.servlet.FilterRegistrationBean]: Factory method ‘httpFilter’ threw exception; nested exception is java.lang.NoClassDefFoundError: javax/servlet/Filter

查看pom文件，找到是内置的tomcat的jar所引起的冲突报错
