Когда я тестирую свой класс @Component, загрузка Spring сообщает, что этот класс должен быть объявлен как @Bean в @Configuration классе:
Field c in org.accountingSpringBoot.AccountingSpringBootApplication required a bean of type 'org.util.Cryptography' that could not be found.
The injection point has the following annotations:
- @org.springframework.beans.factory.annotation.Autowired(required=true)
Action:
Consider defining a bean of type 'org.util.Cryptography' in your configuration.
Код:
Основной класс:
@SpringBootApplication
public class AccountingSpringBootApplication implements CommandLineRunner {
@Autowired
ApplicationContext ctx;
@Autowired
Cryptography c;
public static void main(String[] args) {
SpringApplicationBuilder builder = new SpringApplicationBuilder(AccountingSpringBootApplication.class);
builder.headless(false);
ConfigurableApplicationContext context = builder.run(args);
// SpringApplication.run(AccountingSpringBootApplication.class, args);
}
@Override
public void run(String... args) throws Exception {
System.out.println(c.decrypt(c.encrypt("password")));
}
}
Класс конфигурации:
@Configuration
@PropertySource("classpath:application.properties")
public class AppConfig {
@Autowired
private Environment env;
@Bean
@Scope(scopeName = "singleton")
public SessionHandler sessionHandler() {
return new SessionHandler();
}
@Bean
@Scope(scopeName = "singleton")
public SessionFactory sessionFactory() {
SessionFactory sessionFactory;
try {
sessionFactory = new org.hibernate.cfg.Configuration().configure().buildSessionFactory();
} catch (Throwable ex) {
System.err.println("Initial SessionFactory creation failed." + ex);
throw new ExceptionInInitializerError(ex);
}
return sessionFactory;
}
@Bean
public SecretKey secretKey() {
String secretKey = env.getProperty("crypto.secretkey");
byte[] decodedKey = Base64.getDecoder().decode(secretKey);
SecretKey originalKey = new SecretKeySpec(decodedKey, 0, decodedKey.length,
env.getProperty("crypto.algorithm"));
return originalKey;
}
}
@Component класс:
@Component
public class Cryptography {
@Autowired
private SecretKey secretKey;
private Cipher cipher; // = Cipher.getInstance("AES");
public Cryptography() {
try {
System.out.println("hhhhh");
this.cipher = Cipher.getInstance("AES");
} catch (NoSuchAlgorithmException | NoSuchPaddingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public String encrypt(String plainText) throws Exception {
byte[] plainTextByte = plainText.getBytes();
cipher.init(Cipher.ENCRYPT_MODE, secretKey);
byte[] encryptedByte = cipher.doFinal(plainTextByte);
Base64.Encoder encoder = Base64.getEncoder();
String encryptedText = encoder.encodeToString(encryptedByte);
return encryptedText;
}
public String decrypt(String encryptedText) throws Exception {
Base64.Decoder decoder = Base64.getDecoder();
byte[] encryptedTextByte = decoder.decode(encryptedText);
cipher.init(Cipher.DECRYPT_MODE, secretKey);
byte[] decryptedByte = cipher.doFinal(encryptedTextByte);
String decryptedText = new String(decryptedByte);
return decryptedText;
}
}
