记一次java spring boot 线上无法启动的问题
产生了三次波折。
5-8日，早pom中引入：
<dependency>
<groupId>com.fasterxml.jackson.dataformat</groupId>
<artifactId>jackson-dataformat-xml</artifactId>
<version>2.9.0</version>
</dependency>
线下正常，线上报类：TSFBuilder 找不到，异常信息：

这个类来自于com.fasterxml.jackson.core，且在这个包的2.10.0及以上版本才会有这个类。com.fasterxml.jackson.dataformat依赖了这个包，遂升级版本到2.10.0,。
发布后，线上仍然无法启动且异常依旧（线下开发环境仍然正常）。
随后，手动导入com.fasterxml.jackson.core包，指定版本：
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-core</artifactId>
<version>2.10.0</version>
</dependency>
此时maven出现了版本冲突（会显示两个版本都存在）。但线上环境可以正常发布了（随后没管了）。
两天后，出现线上线下接口接收参数表现不一致的问题。
产生异常：

这个异常是表示，前端传入的某个字段，不在我定义的@ReqeustBody声明的类中（即前端多传了后端用不着的参数）。
但实际上项目中做了MVC的全局配置的，线下是可以正常忽略的，不会报错。此时怀疑jar包冲突导致的，随后通过idea的maven helper插件解决所有已知包冲突。再次发布....
解决冲突后，又出现之前的TSFBuilder类不存在的问题。随后检查代码，看哪里在使用com.fasterxml.jackson.dataformat，发现代码中可以不用到这个包中的类。遂从pom中移除该依赖。
一切恢复正常。
但问题还有待进一步挖掘，为什么线上对应的该包的版本中没有TSFBuilder类？是因为生产环境机器的依赖包中央仓库不一致？
