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

Question

我正在使用 Tomcat 将 .war spring boot 后端部署到 Digital Ocean 上。我不知道如何检查 jar 的运行时版本，因为它是远程运行的，因为它是其他帖子所建议的。谢谢

您很可能会混淆来自不同框架版本的 Spring 依赖项。 StringUtils.matchesCharacter() 方法在Spring 5.2.9 中引入。看起来您使用的是 Spring Boot 2.3.5.RELEASE，它依赖于 Spring 5.2.10，所以您应该没问题，但是：

1. 您正在部署到一个运行时环境，该环境以不同的较低版本提供spring-boot-starter-web jar。

2. 或者依赖 spring-boot-starter-web 不应该在 pom.xml 中标记为 <scope>provided</scope>，因为它在运行时需要。
