java.lang.NoClassDefFoundError:org/springframework/security/converter/RsaKeyConverters

我开始学习spring和spring安全性，我有以下错误。我一直在遵循几条指南，尽管如此，我还是遇到了同样的问题。错误出现在我尝试提升应用程序时

我是spring和spring security的新手，因此非常感谢您的帮助。

我建议您通过从当前构建的spring security核心版本（低于5.2）中删除来解决此问题。它似乎取决于此依赖关系：

<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-web</artifactId>
    <version>4.0.1.RELEASE</version>
</dependency>

org.springframework.security
您使用的是哪个spring-security-oauth.version？它缺少参数的定义。这个错误似乎是由于jar版本不兼容造成的，所以发布所有pom，请
${spring security jwt.version}
和
${spring security oauth.version}
应该引用一些参数或属性，所以也应该有它们的定义，类似于
5.3.6
或者您是用maven命令传递它们的？类似于
mvn安装“-Dsomeproperty=property值”
。如果您需要，请在教程后链接，为了更好地理解它，我刚刚在教程后更新了我的pom.xml:，只需指定spring启动版本，因此我在there's everything上查找兼容版本。无论如何，您不能在Java11中使用spring<5，所以请尝试使用Java1.8或按照教程进行操作
