java Spring REST通过用户角色限制用户访问

2 周，1 日 Questions & Answers 664

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限制对特定用户角色的访问

以下是我的用户模型：

@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
...
}

我已经实现了JWT身份验证。请让我知道我是否也应该上传它

谢谢!
