在Tomcat8.5中部署项目，启动项目就提示jackson-annotations-2.8.0.jar (No such file or directory)

 在Tomcat8.5中部署项目，启动项目就提示jackson-annotations-2.8.0.jar (No such file or directory)，花半天的时间找问题原因，现在已经解决，正好记录一下，预防以后还出现该问题。

主要原因是：jackson-annotations-2.8.0.jar  jackson-core-2.8.10.jar  jackson-databind-2.8.0.jar. 

把pom文件修改为：

             com.fasterxml.jackson.core
             jackson-core
             2.8.0
           
          
              com.fasterxml.jackson.core
              jackson-databind
              2.8.4
          
          
                com.fasterxml.jackson.core
            jackson-annotations
            2.8.0
          

启动项目： springboot项目
