我的申请。班级

@EnableResourceServer
@SpringBootApplication
public class myApplicationApplication {

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

}

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

Answer 1

我建议您通过从当前版本低于5.2的spring security core中删除来修复此问题。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>

通过从我的项目POM中删除旧版本的spring security core，我做到了这一点：

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

我意识到：在有效的pom中，不同的spring security核心版本：

  <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>

但是组织。springframework。安全转换器。RsaKeyConverters类从5.2版本开始出现。你可以在这里看到：https://github.com/spring-projects/spring-security/commit/1c25fe26c9d0241f14f28705ec585aa5c9791ae1#diff-4412eaef26b0242873cc8a9dc5533fee75014866b296e2a3e791c98936607b26

Answer 2

我在使用spring boot安全性时遇到了同样的问题 通过在pom中将这些添加到我的依赖项中，它得到了修复。xml

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-security</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.security</groupId>
            <artifactId>spring-security-core</artifactId>
            <!  <version>5.0.0.RELEASE</version>  >
        </dependency>

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

        </dependency>

        <dependency>
            <groupId>org.springframework.security</groupId>
            <artifactId>spring-security-config</artifactId>
        </dependency>

Answer 3

更新spring安全依赖项

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