a hibernate LazyInitializationException which is very trick - java

I have two piece of code segments, they are almost exactly the same, except their locations are different, one locates in RestLoginDLCtrl(a controller) the other locates in CouponManagerController(a controller).But one code segment is right, the other one throws org.hibernate.LazyInitializationException.
I know how to solve my problem. confused me the most is why one is OK the other is wrong, but they are almost the same code. why? Any help would be appreciate.
ConversionCode is a value object which has a set named codeRewards and managerService is a service class.
note:
Finally, I found some interesting phenomena. when I use ajax way to post the http request, two methods both well:
$.ajax({
type: "POST",
url: "/CouponInfo/useConversionCode.do",
data: {
code: key
},
dataType: "json",
success: function (data) {
}
});
But when I use form way, two methods both did not work:Does hibernate lazy initialize mechnism has relationship with http request way?

Does hibernate lazy initialize mechnism has relationship with http request way?


I know how this issue occured.Suddenly, I found there is a OpenSessionInViewFilter in the web.xml file.
<filter>
<filter-name>OpenSessionInViewFilter</filter-name>
<filter-class>
org.springframework.orm.hibernate3.support.OpenSessionInViewFilter
</filter-class>
<init-param>
<param-name>singleSession</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>OpenSessionInViewFilter</filter-name>
<url-pattern>*.do</url-pattern>
</filter-mapping>
<filter-mapping>
<filter-name>OpenSessionInViewFilter</filter-name>
<url-pattern>*.jsp</url-pattern>
</filter-mapping>
In my form post request way, I did not add the .do request suffix, so the OpenSessionInViewFilter did not work, so the LazyInitializationException occured.
But the ajax post request way added the .do request suffix, so the OpenSessionInViewFilter worked and LazyInitializationException did not occur.

Hibernate is not mapping new attribute on the class

I'm following some tutorials on Hibernate and at a certain point i need to add a new attribute to a class called Produto. It should be no problem since I've done it before and had no issues, but the thing is that when I restart the server, the framework seems to be missing the added field and doesn't add it to the database table, therefore I get erros when I'm trying to use the attribute on my JSP.

Add hibernate.hbm2ddl.auto=update to your property file and restart the application. Hibernate should create the column for you automatically.

I think you must to clean the server from loaded data. Before a few weeks I have the same problem and when I cleaned the resources the problem was solved.

Spring Boot: Configuring AuthenticationManager with custom UserDetailsService

In my Spring Boot application, I am using JWT and a custom UserDetailsService. My AuthenticationManager is configured in a class annotated with #Configuration using the following method:
#Autowired
public void configureGlobal(AuthenticationManagerBuilder auth, DataSource dataSource) throws Exception {
auth
.userDetailsService(userDetailsService)
.and()
.jdbcAuthentication()
.dataSource(dataSource)
.passwordEncoder(passwordEncoder());
}
Even though I specified a UserDetailsService, I am faced with the following problem: When my JWTLoginFilter intercepts the login request, and getAuthenticationManager().authenticate(token)
is called, I get the following exception:
org.springframework.security.authentication.InternalAuthenticationServiceException: PreparedStatementCallback; bad SQL grammar [select username,password,enabled from users where username = ?]; nested exception is com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Table 'butler-test.users' doesn't exist

Setting a query using usersByUsernameQuery(query) on my AuthenticationManagerBuilder solves this problem, but is this the only solution? Shouldn't the UserDetailsService provide the information needed to retrieve the UserDetails for a username?
In case it helps, here is a snippet from the JWTLoginFilter:
#Override
public Authentication attemptAuthentication(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws AuthenticationException, IOException, ServletException {
AccountCredentials credentials = new ObjectMapper().readValue(httpServletRequest.getInputStream(), AccountCredentials.class);
UsernamePasswordAuthenticationToken token = new UsernamePasswordAuthenticationToken(credentials.getUsername(), credentials.getPassword());
return getAuthenticationManager().authenticate(token);
}
This is my user entity (there are subclasses for specific users):

Your configuration is wrong. You defined 2 authentication mechanisms, one is a user details service, and the second is a JDBC authentication.
In order to authenticate a user you only need one kind of mechanism to do that.
Your JVM "complains" about a bad SQL grammar, and if you'll examine the exception more closely you'll see that in particular JVM "complains" that he can't find the users table in your DB.
It seems that your JDBC authentication kicks in and tries to find the user credentials in the users DB table.
When you use this kind of authentication (JDBC) that is where and how Spring will try to authenticate the users, by trying to find a matching record within the users table in your DB.
You obviously mixing 2 authentications mechanisms by trying to read from:
#Table(name = "u_userdetails")
If you want to use JDBC authentication make sure to read the credentials from users table.
And not from:
#Table(name = "u_userdetails")

Spring JPA Lazy Loading - Could Not Initialize Proxy

Below is some code for background:
InitiativeProfileQuestion.java:
#Entity
#Table
public class InitiativeProfileQuestion implements Serializable {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private long id;
#Column(nullable = false)
private String question;
#Column
private String description;
#Column
private int sortOrder;
#OneToMany(mappedBy = "initiativeProfileQuestion", fetch = FetchType.LAZY)
private List<InitiativeProfileAnswer> answers;
public List<InitiativeProfileAnswer> getAnswers() {
return answers;
}
public void setAnswers(List<InitiativeProfileAnswer> answers) {
this.answers = answers;
}
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
public String getQuestion() {
return question;
}
public void setQuestion(String question) {
this.question = question;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
public int getSortOrder() {
return sortOrder;
}
public void setSortOrder(int sortOrder) {
this.sortOrder = sortOrder;
}
}
InitiativeProfileAnswer.java:
#Entity
#Table
public class InitiativeProfileAnswer {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private long id;
#Column
private String answer;
#Column
private int sortOrder;
#ManyToOne(fetch = FetchType.LAZY)
#JoinColumn(name = "initiativeProfileQuestionId")
#JsonIgnore
private InitiativeProfileQuestion initiativeProfileQuestion;
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
public String getAnswer() {
return answer;
}
public void setAnswer(String answer) {
this.answer = answer;
}
public int getSortOrder() {
return sortOrder;
}
public void setSortOrder(int sortOrder) {
this.sortOrder = sortOrder;
}
public InitiativeProfileQuestion getInitiativeProfileQuestion() {
return initiativeProfileQuestion;
}
public void setInitiativeProfileQuestion(InitiativeProfileQuestion initiativeProfileQuestion) {
this.initiativeProfileQuestion = initiativeProfileQuestion;
}
}
InitiativeProfileQuestionRepository.java:
public interface InitiativeProfileQuestionRepository extends JpaRepository<InitiativeProfileQuestion, Long> {
#Query("select ipa from InitiativeProfileQuestion ipa join fetch ipa.answers")
public List<InitiativeProfileQuestion> getAllQuestions();
}
InitiativeProfileService.java:
#Service
public class InitiativeProfileService {
#Autowired
private InitiativeProfileQuestionRepository initiativeProfileQuestionRepository;
public List<InitiativeProfileQuestion> getAllQuestions() {
return initiativeProfileQuestionRepository.findAll();
}
public List<InitiativeProfileQuestion> getAllQuestionsFetch() {
return initiativeProfileQuestionRepository.getAllQuestions();
}
}
BaseController.java:
#RestController
#RequestMapping("/api")
public class BaseController {
#Autowired
InitiativeProfileService initiativeProfileService;
#RequestMapping("/question")
public List<InitiativeProfileQuestion> getQuestions() {
return initiativeProfileService.getAllQuestions();
}
#RequestMapping("/questionFetch")
public List<InitiativeProfileQuestion> getQuestionsFetch() {
return initiativeProfileService.getAllQuestionsFetch();
}
}
Calling getQuestions() in my BaseController returns a "could not initialize proxy - no Session" error. However, calling getQuestionsFetch() in my BaseController loads just fine.
I want it to work in a way that if I call getQuestions(), the object will be returned with NO answers (since the lazy loaded object will not be called anywhere). However, it just gives me an error. If I'm doing a query with a join fetch, it works by showing the answers as well (expected behavior).
What am I doing wrong? I tried #Transactional in different places with no luck. I also have no .xml files- everything so far is done using annotations.
The error I get is:

For an exception in case of lazy loading you must be trying to fetch the associated objects outside the session. Either change the lazy loading to eager or put your code which is fetching the associated object inside the session.
For e.g:
public void test() {
Session session = HibernateUtil.currentSession();
session.beginTransaction();
Vehicle vehicle= (Vehicle) session.get(Vehicle.class, 2);
System.out.println(vehicle.getVehicleName());
session.getTransaction().commit();
session.close();
System.out.println(vehicle.getVehicleName()); //No exception here
System.out.println(vehicle.getUser().getUserName());
// Exception here change the loading to EAGER or put this line of code within the session above. Put it before session.close() or before session.getTransaction().commit();
}

As you can see from the stacktrace, the error occurs when Jackson is trying to access the lazily loaded object in order to serialize it to JSON. At this time, the spring transaction has already completed, and the Hibernate session closed, which is why Hibernate can no longer load that object.
If you do not intend that field to be serialized, you might wish to use #JsonIgnore, or Spring's Jackson Serialization View Support.

I guess you should write like this : (by considering you want to update LoginHistory which is already in DB having id that you are passing)
hibernate query :
sessionFactory.getCurrentSession().beginTransaction();
Criteria criteria = sessionFactory.getCurrentSession().createCriteria(LoginHistory.class);
criteria.add(Restrictions.eq("id",id));
LoginHistory loginHistory = (LoginHistory)criteria.uniqueResult();
loginHistory.setLogoutTime(AdminUtil.getTimeStamp());
sessionFactory.getCurrentSession().update(loginHistory);

java jpa ManyToOne cascade remove not working as expected

I have two tables and on one of which I want to perform cascade on delete operation. I have tried using annotations both on the variable and on the getter method as well, but the variable one gives me this error:

And here is my child class where I have used many to one annotation:

import javax.persistence.Entity;
import javax.persistence.Table;
#Entity
#Table(name="ac_ua_ip")
public class IPUser extends BaseEntity{

private String ip;
private String comment;
private UserAccount userAccount;
public IPUser(){
}
public IPUser (String ip, String comment, UserAccount userAccount){

this.comment = comment;
this.setUserAccount(userAccount);
}
#Column (nullable = false)

}
#Column

public void setComment(String comment) {

}
#ManyToOne(cascade = CascadeType.REMOVE)
public UserAccount getUserAccount() {
return userAccount;
}
public void setUserAccount(UserAccount userAccount) {
this.userAccount = userAccount;
}
}
And, I have removed lot of methods from parent class here just to have a clarity.
Any suggestions as to what I am doing wrong?

You will have to manage that problem manually, as it really does NOT make sense to cascade the remove operations from a ManyToOne relationship (otherwise your DB will not be consistent, as there could remain some IPUser entities without UserAccount).
See this answer for an excerpt from the JPA specification + a similar problem.

Alright, here's how I made it work.
I hope it goes all ok with the etiquette of answering self-asked-questions.
I added a reference to IPUser class in UserAccount class and it worked smoothly now. Here is the snippet I added:
private List<IPUser> ipUserList;
#OneToMany(mappedBy = "userAccount", fetch = FetchType.LAZY)
#Cascade({CascadeType.DELETE})
public List<IPUser> getIpUserList() {
return ipUserList;
}
public void setIpUserList(List<IPUser> ipUserList) {
this.ipUserList = ipUserList;
}
Please feel free to update my answer or ask any question regarding this.
