I'm using Spring Data JPA 1.6.4 with Hibernate 4.3.6.Final + envers into a Spring MVC 4 web application secured with Spring Security 3.2.5. The web application is deployed on a Tomcat 7.0.52 web container, configured with a JNDI datasource:
Code:
<Resource
name="jdbc/appDB"
auth="Container"
factory="org.apache.tomcat.jdbc.pool.DataSourceFactory"
type="javax.sql.DataSource"
initialSize="4"
maxActive="8"
maxWait="10000"
maxIdle="8"
minIdle="4"
username="user"
password="password"
driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://ip/schema?zeroDateTimeBehavior=convertToNull"
testOnBorrow="true"
testWhileIdle="true"
validationQuery="select 1"
validationInterval="300000" />
I have a strange behaviour with audit table Customers_H: noticed that sometimes audit tables are populated in a wrong way by envers,
I have no idea of why and when It happens, but I have as a result a revision table like the following:
Code:
ID ACTION TYPE REV END USER
23 0 256 U1
23 2 NULL NULL
23 0 NULL U2
The strange thing is that U1 is the owner of an entity with id = 6 (not of the entity with id = 23!), while U2 has really worked on entity ID 23. The problem is that the revision table is inconsinstent and then I have an Hibernate ASSERTION FAILURE
ERROR org.hibernate.AssertionFailure - HHH000099: an assertion failure occured (this may indicate a bug in Hibernate, but is more likely due to unsafe use of the session): java.lang.RuntimeException: Cannot update previous revision for entity Customer_H and id 23.
This prohibit user to update the entity.
My problem is to investigate how this can happen!
Here is Customer domain:
Code:
@SuppressWarnings("serial")
@Entity
@Audited
public class Customer extends AbstractDomain{
@ManyToOne(optional=false)
@JoinColumn(updatable=false, nullable=false)
@JsonIgnore
private Company company;
@OneToMany(mappedBy="customer", cascade=CascadeType.REMOVE)
private Set<Plant> plants = new HashSet<Plant>();
@Enumerated(EnumType.STRING)
@Column(nullable=false)
private CustomerType customerType;
private String code;
// other basic fields + getter and settes
}
Here is AbstractDomain class:
Code:
@SuppressWarnings("serial")
@MappedSuperclass
@Audited
public abstract class AbstractDomain implements Auditable<String, Long>, Serializable {
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
private Long id;
@Version
@JsonIgnore
private int version;
@JsonIgnore
@Column(updatable=false)
private String createdBy;
@Type(type="org.jadira.usertype.dateandtime.joda.PersistentDateTime")
@DateTimeFormat(iso=ISO.DATE_TIME)
@JsonIgnore
@Column(updatable=false)
private DateTime createdDate;
@JsonIgnore
private String lastModifiedBy;
@Type(type="org.jadira.usertype.dateandtime.joda.PersistentDateTime")
@DateTimeFormat(iso=ISO.DATE_TIME)
@JsonIgnore
private DateTime lastModifiedDate;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public int getVersion() {
return version;
}
public void setVersion(int version) {
this.version = version;
}
@Override
public String getCreatedBy() {
return createdBy;
}
@Override
public void setCreatedBy(String createdBy) {
this.createdBy = createdBy;
}
@Override
public DateTime getCreatedDate() {
return createdDate;
}
@Override
public void setCreatedDate(DateTime createdDate) {
this.createdDate = createdDate;
}
@Override
public String getLastModifiedBy() {
return lastModifiedBy;
}
@Override
public void setLastModifiedBy(String lastModifiedBy) {
this.lastModifiedBy = lastModifiedBy;
}
@Override
public DateTime getLastModifiedDate() {
return lastModifiedDate;
}
@Override
public void setLastModifiedDate(DateTime lastModifiedDate) {
this.lastModifiedDate = lastModifiedDate;
}
@Transient
@Override
public final boolean isNew() {
if (id == null) {
return true;
} else {
return false;
}
}
}
Here is CustomerService:
Code:
@Service
@Repository
@Transactional(readOnly=true)
public class CustomerServiceImpl implements CustomerService{
@Autowired
private CustomerRepository customerRepository;
@Override
@PostAuthorize("@customerSecurityService.checkAuth(returnObject)")
public Customer findById(Long id) {
return customerRepository.findOne(id);
}
@Override
@PreAuthorize("isAuthenticated()")
@Transactional(readOnly=false)
public Customer create(Customer entry) {
entry.setCompany(SecurityUtils.getCustomer().getCompany());
return customerRepository.save(entry);
}
@Override
@PreAuthorize("@customerSecurityService.checkAuth(#entry)")
@Transactional(readOnly=false)
public Customer update(Customer entry) {
return customerRepository.save(entry);
}
....
}
Here is my CustomerRepository
public interface CustomerRepository extends PagingAndSortingRepository<Customer, Long>, QueryDslPredicateExecutor<Customer> {
}
Here the Service I use to do security checks in @PreAuthorize @PostAuthorize annotations in CustomerService methods:
Code:
@Component
@Transactional(readOnly=true)
public class CustomerSecurityService {
Logger LOGGER = LoggerFactory.getLogger(CustomerSecurityService.class);
@Autowired
private CustomerRepository customerRepository;
public boolean checkAuth(Customer customer) {
if(customer == null) {
LOGGER.error("customer NULL!");
return false;
}
if (customer.getId()==null) {
return true;
}
if (customer.getId()!=null) {
Customer dbCustomer = customerRepository.findOne(customer.getId());
if (dbCustomer.getCompany().getId().equals( SecurityUtils.getCustomer().getCompany().getId())){
return true;
}else {
return false;
}
}
return false;
}
public boolean checkPage(Page<Customer> pages) {
for(Customer customer : pages.getContent()) {
Customer dbCustomer = customerRepository.findOne(customer.getId());
if (!dbCustomer.getCompany().getId().equals(SecurityUtils.getCustomer().getCompany().getId())){
return false;
}
}
return true;
}
}
My SecurityUtils class
Quote:
public class SecurityUtils {
private SecurityUtils(){}
private static Logger LOGGER = LoggerFactory.getLogger(SecurityUtils.class);
public static Customer getCustomer() {
Customer customer = null;
if (SecurityContextHolder.getContext().getAuthentication()!=null) {
customer = ((User)SecurityContextHolder.getContext().getAuthentication().getPrincipal()).getCustomer();
LOGGER.debug("Customer found: "+customer.getUserName());
}else {
LOGGER.debug("Customer not bound.");
}
return customer;
}
public static boolean isUserInRole(String role) {
for (GrantedAuthority grantedAuthority : SecurityContextHolder.getContext().getAuthentication().getAuthorities()) {
if (grantedAuthority.getAuthority().equals(role)) {
return true;
}
}
return false;
}
}

In the project I have about 50 domain classes, some of them with Inheritance Table_Per_Class.
The application is now used by few users, that are not connected at the same time. So I can say that only one user is using my application at a given time.
I also not understand how can I make an unsafe use of the Session. I never work directly with Hibernate Session. I always use a higher level abstraction with Spring Data Repositories. Sometimes I need to extends JpaRepository interface in order to call saveAndFlush() or explicitly call flush(). Maybe that the cause?
I can't understand this behaviour! Any suggestion would be appreciated!!
