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

Question

开始学习spring和spring security出现如下错误。我一直在关注几个指南，但我都遇到了同样的问题。错误是当我尝试解除应用程序时

我的应用程序类

@EnableResourceServer
@SpringBootApplication
public class myApplicationApplication {

    public static void main(String[] args) {
        SpringApplication.run(myApplicationApplication.class, args);
    }

}

我是 spring 和 spring 安全方面的新手，所以非常感谢任何帮助。

我建议您通过从低于 5.2 的 spring-security-core 版本的当前构建中删除来解决这个问题。看起来它取决于此依赖项:

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

我通过从我的项目 POM 中删除旧版本 spring-security-core 来实现这一点:

  <dependencies>
        <dependency>
            <groupId>org.springframework.security</groupId>
            <artifactId>spring-security-core</artifactId>
<!--            <version>5.1.6.RELEASE</version>-->
        </dependency>

我已经意识到:在 effective-pom 中如此不同的 spring-security-core 版本:

  <dependencies>
    <dependency>
      <groupId>org.springframework.security</groupId>
      <artifactId>spring-security-core</artifactId>
      <version>5.4.2</version>
      <scope>compile</scope>
    </dependency>
    </dependencies>
  </dependencyManagement>

  <dependencies>
    <dependency>
      <groupId>org.springframework.security</groupId>
      <artifactId>spring-security-core</artifactId>
      <version>5.1.6.RELEASE</version>
      <scope>compile</scope>
    </dependency>

但是 org.springframework.security.converter.RsaKeyConverters 类是从 5.2 版本开始出现的。你可以在这里看到:https://github.com/spring-projects/spring-security/commit/1c25fe26c9d0241f14f28705ec585aa5c9791ae1#diff-4412eaef26b0242873cc8a9dc5533fee75014866b296e2a3e791c98936607b26
