我有一个问题:连接到mySql。有没有人知道如何解决这个问题? 我想加密我的数据库密码。
我有加密密码。我的代码正在解密。我希望不会。
你能帮我吗?(

初始问题:由以下原因引起:java.sql.SQLException:用户的访问被拒绝
根据C3P0ConnectionProvider (Hibernate 5)和EncryptedPasswordC3P0ConnectionProvider (Hibernate 4),configure方法定义为
void configure(java.util.Map props)
代表休眠5 和void configure(java.util.Properties props)
用于休眠4 。但是,在您的代码中,您拥有void configure(final Properties props)
但使用了Hibernate5。因此,您需要使用正确的方法定义(使用Map而不是Properties)。
我会尝试:
import java.util.Map;
import org.hibernate.c3p0.internal.C3P0ConnectionProvider;
import org.hibernate.cfg.AvailableSettings;
import org.jasypt.encryption.pbe.PBEStringEncryptor;
import org.jasypt.exceptions.EncryptionInitializationException;
import org.jasypt.hibernate4.connectionprovider.ParameterNaming;
import org.jasypt.hibernate4.encryptor.HibernatePBEEncryptorRegistry;
import org.jasypt.properties.PropertyValueEncryptionUtils;
public final class EncryptedPasswordC3P0ConnectionProvider extends C3P0ConnectionProvider {
public EncryptedPasswordC3P0ConnectionProvider() {
// call the constructor of the super class
super();
}
// configure method get a Map object (old hibernate version got a Properties object)
public void configure(Map props) {
final String encryptorRegisteredName =
(String) props.get(ParameterNaming.ENCRYPTOR_REGISTERED_NAME);
final HibernatePBEEncryptorRegistry encryptorRegistry =
HibernatePBEEncryptorRegistry.getInstance();
final PBEStringEncryptor encryptor =
encryptorRegistry.getPBEStringEncryptor(encryptorRegisteredName);
// encryptor should never be null
if (encryptor == null) {
throw new EncryptionInitializationException(
"No string encryptor registered for hibernate " +
"with name \"" + encryptorRegisteredName + "\"");
}
// Get the original values from your hibernate config file
final String user = (String) props.get(AvailableSettings.USER);
final String password = (String) props.get(AvailableSettings.PASS);
final String driver = (String) props.get(AvailableSettings.DRIVER);
final String url = (String) props.get(AvailableSettings.URL);
// Perform decryption operations as needed and store the new values
if (PropertyValueEncryptionUtils.isEncryptedValue(driver)) {
props.put(
AvailableSettings.DRIVER,
PropertyValueEncryptionUtils.decrypt(driver, encryptor));
}
if (PropertyValueEncryptionUtils.isEncryptedValue(url)) {
props.put(
AvailableSettings.URL,
PropertyValueEncryptionUtils.decrypt(url, encryptor));
}
if (PropertyValueEncryptionUtils.isEncryptedValue(user)) {
props.put(
AvailableSettings.USER,
PropertyValueEncryptionUtils.decrypt(user, encryptor));
}
if (PropertyValueEncryptionUtils.isEncryptedValue(password)) {
props.put(
AvailableSettings.PASS,
PropertyValueEncryptionUtils.decrypt(password, encryptor));
}
// Let Hibernate framework do the rest
super.configure(props);
}
}
... // your getters, setters, ...
}
