I need to authenticate users from database, Spring Security documents don't tell how to authenticate with hibernate. Is that possible and how can I do that?
You have to make your own custom authentication-provider.
Example code:
Service to load Users from Hibernate:
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
@Service("userDetailsService")
public class UserDetailsServiceImpl implements UserDetailsService {
@Autowired private UserDao dao;
@Autowired private Assembler assembler;
@Transactional(readOnly = true)
public UserDetails loadUserByUsername(String username)
throws UsernameNotFoundException, DataAccessException {
UserDetails userDetails = null;
UserEntity userEntity = dao.findByName(username);
if (userEntity == null)
throw new UsernameNotFoundException("user not found");
return assembler.buildUserFromUserEntity(userEntity);
}
}
Service to convert your entity to a spring user object:
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.GrantedAuthorityImpl;
import org.springframework.security.core.userdetails.User;
@Service("assembler")
public class Assembler {
@Transactional(readOnly = true)
User buildUserFromUserEntity(UserEntity userEntity) {
String username = userEntity.getName();
String password = userEntity.getPassword();
boolean enabled = userEntity.isActive();
boolean accountNonExpired = userEntity.isActive();
boolean credentialsNonExpired = userEntity.isActive();
boolean accountNonLocked = userEntity.isActive();
Collection<GrantedAuthority> authorities = new ArrayList<GrantedAuthority>();
for (SecurityRoleEntity role : userEntity.getRoles()) {
authorities.add(new GrantedAuthorityImpl(role.getRoleName()));
}
User user = new User(username, password, enabled,
accountNonExpired, credentialsNonExpired, accountNonLocked, authorities, id);
return user;
}
}
The namespace-based application-context-security.xml would look something like:
<http>
<intercept-url pattern="/login.do*" filters="none"/>
<intercept-url pattern="/**" access="IS_AUTHENTICATED_ANONYMOUSLY" />
<form-login login-page="/login.do"
authentication-failure-url="/login.do?error=failed"
login-processing-url="/login-please.do" />
<logout logout-url="/logoff-please.do"
logout-success-url="/logoff.html" />
</http>
<beans:bean id="daoAuthenticationProvider"
class="org.springframework.security.authentication.dao.DaoAuthenticationProvider">
<beans:property name="userDetailsService" ref="userDetailsService"/>
</beans:bean>
<beans:bean id="authenticationManager"
class="org.springframework.security.authentication.ProviderManager">
<beans:property name="providers">
<beans:list>
<beans:ref local="daoAuthenticationProvider" />
</beans:list>
</beans:property>
</beans:bean>
<authentication-manager>
<authentication-provider user-service-ref="userDetailsService">
<password-encoder hash="md5"/>
</authentication-provider>
</authentication-manager>
