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

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

我正在使用 Tomcat 将 .war spring 启动后端部署到 Digital Ocean。我不确定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

解决方法

您很可能混淆了来自不同框架版本的 Spring 依赖项。 StringUtils.matchesCharacter() 方法是在 Spring 5.2.9 中引入的。看起来您正在使用依赖于 Spring 5.2.10 的 Spring Boot 2.3.5.RELEASE 所以你应该没问题，但是：

1. 您要么部署到提供 spring-boot-starter-web 不同较低版本 jar 的运行时环境。

2. 或者不应该在 pom.xml 中将依赖项 spring-boot-starter-web 标记为 <scope>provided</scope>，因为它是运行时需要的。
