java.lang.NoSuchMethodError:org.springframework.util.StringUtils.MatcheCharacter（Ljava/lang/String；C）Z

我正在使用Tomcat将.war spring引导后端部署到Digital Ocean上。我不知道如何像其他帖子建议的那样检查jar的运行时版本，因为这是远程运行的。谢谢

信息

Handler dispatch failed; nested exception is java.lang.NoSuchMethodError: org.springframework.util.StringUtils.matchesCharacter(Ljava/lang/String;C)Z

谢谢。

您很可能混淆了来自不同框架版本的Spring依赖项

StringUtils.MatcheCharacter（）

方法是在中引入的。看起来您使用的是Spring Boot 2.3.5.RELEASE，它取决于Spring 5.2.10，因此您应该很好，但是：

您可以部署到一个运行时环境，该环境以不同的较低版本提供

springbootstarterweb

jar

或者，不应在pom.xml中将依赖项

spring boot starter web

标记为提供的

，因为它是运行时需要的

谢谢，在干净的安装后工作得很好。您可以通过取消归档war并检查lib文件夹来进行检查

jar-xvf你的.war
