java spring boot编写一个简单的 授权码功能
以下是一个简单的授权码功能的实现示例,使用Java Spring Boot框架:
- 定义授权码类:
public class AuthorizationCode {
private String code;
private String clientId;
private LocalDateTime expiresAt;
// 构造函数、getter和setter方法
}
- 定义授权码存储类:
@Component
public class AuthorizationCodeStore {
private Map<String, AuthorizationCode> codeMap = new HashMap<>();
public void save(AuthorizationCode code) {
codeMap.put(code.getCode(), code);
}
public AuthorizationCode get(String code) {
return codeMap.get(code);
}
public void delete(String code) {
codeMap.remove(code);
}
}
- 定义授权码生成器类:
@Component
public class AuthorizationCodeGenerator {
private SecureRandom secureRandom = new SecureRandom();
public AuthorizationCode generate(String clientId) {
String code = new BigInteger(130, secureRandom).toString(32);
LocalDateTime expiresAt = LocalDateTime.now().plusMinutes(10);
AuthorizationCode authCode = new AuthorizationCode();
authCode.setCode(code);
authCode.setClientId(clientId);
authCode.setExpiresAt(expiresAt);
return authCode;
}
}
- 定义授权码控制器类:
@RestController
@RequestMapping("/authorize")
public class AuthorizationCodeController {
@Autowired
private AuthorizationCodeGenerator codeGenerator;
@Autowired
private AuthorizationCodeStore codeStore;
@PostMapping("/code")
public ResponseEntity<String> getCode(@RequestParam String clientId) {
AuthorizationCode code = codeGenerator.generate(clientId);
codeStore.save(code);
return ResponseEntity.ok(code.getCode());
}
@GetMapping("/validate")
public ResponseEntity<Void> validateCode(@RequestParam String code) {
AuthorizationCode authCode = codeStore.get(code);
if (authCode == null || authCode.getExpiresAt().isBefore(LocalDateTime.now())) {
return ResponseEntity.status(HttpStatus.UNAUTHORIZED).build();
} else {
codeStore.delete(code);
return ResponseEntity.ok().build();
}
}
}
- 在应用程序启动类上添加@EnableWebMvc注解:
@SpringBootApplication
@EnableWebMvc
public class MyApp {
public static void main(String[] args) {
SpringApplication.run(MyApp.class, args);
}
}
这个授权码功能的实现示例使用了内存存储,实际应用中可以使用数据库或缓存等持久化存储方案。此外,还需要考虑安全性和性能等方面的问题。
