com/ibm/icu/text/RuleBasedCollator 的 Spring NoClassDefFoundError

Question

我对以下错误感到非常困惑。 我不知道这是从哪里来的，因为它没有在我的应用程序中使用。 我尝试在 war 文件中添加此依赖项，但它不起作用。

org.springframework.web.util.NestedServletException: 
Handler dispatch failed; nested exception is

由于是spring抛出的嵌套异常，所以我弄清楚了错误发生的流程。它是在使用第三方ims库进行交易时发生的。 我查看了图书馆，瞧，jar ICU4J 不见了。 添加后问题解决了。
