该问题在项目使用Maven clean install的时候出现的，一开始想的是，是否与这个jar包 (bcpkix-jdk15on-1.70.jar) 有关系？但是在pom文件中把对应的依赖注释掉后，并没有解决问题。

看一下完整的报错解析，关键在于两个路径。发现是打包的时候，有一步操作需要把\src\main\resources\lib\下的jar包转移到target\classes\lib\之下，但是Input length说明导入的jar包数目不对。

原因分析：

因为项目需要用到一些外部jar包，一开始是使用如以下这种相对路径的方式引入,并把jar包放置在${project.basedir}/src/main/resources/lib/之下。
