smartbi9.7 版本 使用java sdk 报错

Caused by: java.lang.NoClassDefFoundError: Could not initialize class smartbi.util.StringUtil
    at smartbi.sdk.service.spreadsheetreport.SSReport.refreshByJson(SSReport.java:64) ~[sdk-8.0.38363.18205.jar:na]
    at smartbi.sdk.service.spreadsheetreport.SSReport.open(SSReport.java:45) ~[sdk-8.0.38363.18205.jar:na] 

看报错搜索引擎上挺多可能性的，建议是跟着排查一下https://wenku.csdn.net/answer/54f210e6167d88b495d4e2dc49eced01
