Caused by: java.lang.NoSuchMethodError: com/krm/slsint/fileRepositoryManage/services/FileRepositoryService.saveFileDataforjianguan(Ljava/util/List;)
这种错误一般都是 jar包 或 class文件 不匹配所导致，也就是：
1、你在某个版本对某个class增加了一个方法；或使用了一个高版本jar包所提供的新方法；
2、其它类调用了该方法；
3、但是发布到系统上时，并没有发布新的这个class或高版本jar包；
4、结果JVM按代码去找这个新方法的时候，虽然找到了类，但是却找不到这个新方法，然后就出错了。
总的来说就是部署问题，去检查吧。
[其他解释]
可能是你版本没有全部更新，找不到方法
[其他解释]
代码是最新更新且在本地测试过打包好的吗？
Caused by: java.lang.NoSuchMethodError: com/krm/slsint/fileRepositoryManage/services/FileRepositoryService.saveFileDataforjianguan
看样子应该是接口没更新好、
你得要最新打包好的代码哦
[其他解释]
保存方法出错。方法或参数值可能错了
[其他解释]
你本地代码没错 。 那就是客户那的JAR包等配置出错
[其他解释]
如果确定有这个方法，执行时还是报这样滴错，重启下，然後看下你配置文件里面配置好了没
[其他解释]
查看下文件写入的目标目录的读写权限。。。一般是这个问题
