如何在java spring boot中从请求头中获取持有者令牌？

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

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .authorizeRequests()
                .anyRequest().authenticated()
                .and()
            .oauth2ResourceServer()
                .jwt();
    }
}

@RestController
public class MyController {

    @GetMapping("/example")
    public ResponseEntity<String> getExample(@RequestHeader("Authorization") String bearerToken) {
        // 从请求头中获取持有者令牌（Bearer Token）
        // 在这里可以对令牌进行验证、解析等操作
        return ResponseEntity.ok("Bearer Token: " + bearerToken);
    }
}
