Spring REST 按用户角色限制用户访问

Question

我有几个用户角色，比如说：用户和管理员。我只想将某些路由的访问权限授予具有管理员角色的用户。例如对于这条路线：@GetMapping("/all")public ResponseEntity getAll(){    List<User> users = this.userRepository.findAll();    return new ResponseEntity<>(users, HttpStatus.OK);}如何在 Spring 中创建不同的中间件，以便我可以使用它们来限制对某个用户角色的访问？这是我的用户模型：@Entity@Table(name = "users")public class User implements Serializable {private static final long serialVersionUID = -7643506746013338699L;public User() { }public User(String username, String email, String password, String firstName, String lastName) {    this.username = username;    this.password = password;    this.firstName = firstName;    this.lastName = lastName;    this.email = email;}@Id@NotEmpty@Size(min = 5, max = 15)@Column(name = "username")private String username;@Email@NotEmpty@Column(name = "email")private String email;@NotEmpty@Size(min = 5)@Column(name = "password")private String password;//some more user properties...@ManyToMany(fetch=FetchType.EAGER)@JoinTable(name = "user_roles", joinColumns = @JoinColumn(name = "username"), inverseJoinColumns = @JoinColumn(name = "role_id"))private Set<Role> roles = new HashSet<>();// getters and setters...}我实现了 JWT 身份验证。请让我知道我是否也应该上传它。

您可以在 spring 安全配置https://github.com/spring-projects/spring-security/blob/master/samples/boot/oauth2resourceserver/src/main/ 中的路由“/all”上使用 hasRole("ADMIN") java/sample/OAuth2ResourceServerSecurityConfiguration.java

否则你可以像这样从 Jwt 中提取角色并测试正确的角色：
