these days I meet a problem, I can not figure it out,so please help me...
My entity: Utilisateur this is a french word means user
#Entity
#Inheritance(strategy = InheritanceType.JOINED)
public class Utilisateur implements Serializable
{
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
protected int id;
protected String login;
protected String password;
protected String nom;
protected String prenom;
protected String email;
protected String username;}
#OneToOne(mappedBy="user", cascade={CascadeType.ALL})
private Role role;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getUsername() {
return login;
}
public void setUsername(String username) {
this.username = username;
}
public String getLogin() {
return login;
}
public void setLogin(String login) {
this.login = login;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getNom() {
return nom;
}
public void setNom(String nom) {
this.nom = nom;
}
public String getPrenom() {
return prenom;
}
public void setPrenom(String prenom) {
this.prenom = prenom;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public Role getRole() {
return role;
}
public void setRole(Role role) {
this.role = role;
}
}
and a Role entity.
In my web app, there is a controller to show for example the information about a student(Etudiant in french)
#EJB(mappedName = "Etudiant.EtudiantFacade")
EtudiantFacade etudiantF;
// Affiche le detail d'un Etudiant (show the infomations of the student)
#RequestMapping(value = "/Etudiant/{idEtudiant}/info")
public ModelAndView detail(#PathVariable String idEtudiant, Model m) {
m.addAttribute("etudiant",
etudiantF.trouver(Integer.parseInt(idEtudiant)));
return new ModelAndView("EtudiantInformation", "null", null);
}
I implemented my own CustomUseDetailService using the entity Utilisateur directly.
#Override
public UserDetails loadUserByUsername(String username)
throws UsernameNotFoundException, DataAccessException {
// TODO Auto-generated method stub
System.out.println("!!!!!!!!!!!!!!!!!");
System.out.println(username);
boolean enabled = true;
boolean accountNonExpired = true;
boolean credentialsNonExpired = true;
boolean accountNonLocked = true;
Utilisateur etudiant = etudiantF.trouverParLogin(username);
return new User(etudiant.getLogin(), etudiant.getPassword(), enabled,accountNonExpired,credentialsNonExpired,accountNonLocked,getAuthorities(etudiant.getRole().getRole()));
}
and my security.xml is below:
<http auto-config="true" use-expressions="true">
<intercept-url pattern="/app/Login" access="permitAll"/>
<intercept-url pattern="/app/*" access="hasAnyRole('ROLE_ADMIN','ROLE_USER')"/>
<form-login login-page="/app/Login"
authentication-success-handler-ref="authenticationSuccessHandler"/>
<logout logout-url="/app/Logout" logout-success-url="/"/>
</http>
<authentication-manager alias="authenticationManager">
<authentication-provider user-service-ref="customUserDetailsService"/>
</authentication-manager>
Last my question is:
for a student, his id is 1, his username is stu1,to control this student with id 1 can only access his own page information /ProjetName/Student/{studentId}/Info
how do I write the code with #PreAuthorize, I have see the document in form spring, there is example like #PreAuthorize(#contract.name = principal.username), because there is a attribute username in principal, but here,what I need is Id, I use #RequestMapping(value = "/Etudiant/{idEtudiant}/info") to match the student not the username. So how can I solve it? Many thanks... I can not find the tutorial.
You can provide your own implementation for User class (just extend org.springframework.security.core.userdetails.User). Add an identifier field to it. Then set corresponding value in loadUserByUsername method:
#Override
public UserDetails loadUserByUsername(String username)
...
return new CustomUser(etudiant.getId(), etudiant.getLogin(), etudiant.getPassword(), enabled,accountNonExpired,credentialsNonExpired,accountNonLocked,getAuthorities(etudiant.getRole().getRole()));
}
Then you will be able to use it:
#PreAuthorize(#contract.name = principal.id)

bellow is what Iam sending in the post request in the postman:
{
"FirstName":"jack",
"LastName":"testjack",
"Password":"124",
"Email":"emailTest#gmail.com"
}
The issue is in json to java Model mapping.
You need to rename your Model.java properties in this way:
Email -> email
FirstName -> firstName
Or add #JsonProperty("name"):
#JsonProperty("email")
private String Email;
Don't forget json changes, if you choose properties renaming:
{
"firstName":"jack",
"lastName":"testjack",
"password":"124",
"email":"emailTest#gmail.com"
}
I have a User Entity and an Order Entity.
One of the field in order entity is date.
Till now i have the user enter the date.
Now i want that at the time post request is made the date is automatically set to the current date and stored in the database.
Tried using #Prepersist annotation But since this is my first API that i am developing using springBoot , I don't really know how to use it.

Order Controller

public Iterable<Orders> getAllOrders()
{
return ordersService.getAllOrders();
}

{
return ordersService.getOrderById(orderId);

#RequestMapping(method = RequestMethod.POST,value = "/users/{userId}/orders")
public Orders addOrder(#PathVariable BigInteger userId,#RequestBody Orders orders) {
orders.setUser(new User(userId," ",0000000000L," "));
return ordersService.addOrder(orders);
}
#ApiOperation(value="Alter an Order")

}
}
#PrePersist is a JPA annotation and therefore should work in all compatible persistence frameworks. It indicates a method that should be invoked on particular entity lifecycle event. (Other events are well documented in the Hibernate user guide here).
Add this to your entity:
#Temporal(TemporalType.TIMESTAMP)
#Column(nullable = false)
private Date timestamp;
#PrePersist
private void onCreate() {
timestamp = new Date();
}
As for assigning/creating the entity in the controller, it is a good practice to use DTO (data transfer objects) in your controller (#RequestBody OrderDto orderDto) and then use some method to populate a new entity instance with those values. Most common options are
modelmapper
manually
...
Order o = new Order();
o.user = userDao.findById(orderDto.getUserId());
...
// persist o

Caused by: org.postgresql.util.PSQLException: ERROR: syntax error at or near "user"
Position: 108
as you can see the error points on USER entity. but the same entity runs fine when the application is connected to mysql database. i could not quite figure out what is the real error behind it.
User is actually a reserved keyword that Spring JPA doesn't "escape" as-is. However, you can do the keyword escape like so in your entity declaration:
#Entity
#Table(name = "\"User\"")
public class User implements UserDetails { ... }
Spring is likely escaping it for you in your MySql database or taking care of it for you in some other way; not the case for your PostgreSQL DB.
Not sure why I have an issue here, but when I save with a CrudRepository with these objects, I get the SerializationException (with no further information). Can someone take a look at my objects and offer me some insight into why they can't serialize? My pom.xml is attached last as well in case that helps somehow. I'm using a Postgres database.
EDIT: The database and now - tables are created, but objects are not creating rows.

Thanks for your help!
Mike
Hm, this seems multi-faceted. Let's see if I can help at all. Last thing first...
No tables being created automatically.
I would take a look at this section in Spring's docs for the most basic approach: Initialize a database using Hibernate. For example, spring.jpa.hibernate.ddl-auto: create-drop will drop and re-create tables each time the application runs. Simple and easy for initial dev work. More robust would be leveraging something like Flyway or Liquibase.
Serialization issue
So without logs, and the fact that you have no tables created, the lack of a persistence layer would be the assumed culprit. That said, when you have tables and data, if you do not have a repository for all of the related tables, you'll end up with a StackOverflow error (the serialization becomes circular). For that, you can use #JsonBackReference (child) and #JsonManagedReference (parent). I have been successful using only #JsonBackReference for the child.
Items[]
I'm not sure what Item.class looks like, but that looks like an offensive configuration that I missed the first round.
Change private Items[] items; to private List<Item> items = new ArrayList<Item>();. Annotate with #ElementCollection.
Annotate Item.class with #Embeddable.
I have a client app:
public static void main(String[] args) throws NamingException {
Properties p = new Properties();
p.put(Context.PROVIDER_URL, "t3://127.0.0.1:7001");
p.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
InitialContext ctx = new InitialContext(p);
ServiceEJBStatelessRemote service = (ServiceEJBStatelessRemote)ctx.lookup("ServiceEJBStatelessJNDI#com.marcos.service.remote.ServiceEJBStatelessRemote");
User user = new User(123, "Foo BAR", "ertddeew45", "foousername");
Long id = service.insertUser(user);
System.out.println("User has been created with id: "+id);
Whenever I try to persist this entity in the DB, I get no exception but isn't getting stored in my DB.
In my service (stateless EJB), I have two methods, one for insert and another for retrieve; the retrieving method works just fine, so then I can see that the Entity Manager attribute works, and my persistance unit as well as I can go to the DB and retrieve the value Im looking for.
But when I invoke the insertUser() method, I get no error but the entity is not saved it in the DB, it is like if there were no commit action at all.
Im deploying my app in a Weblogic 12c server
In order to run my client app, Im adding wlthint3client.jar into my buildpath
In my insertUser() method I cant make any call to getTransaction() cos then I get an exeception.
Am I missing something?
This is my service class:
#Stateless(mappedName = "ServiceEJBStatelessJNDI", name="ServiceEJBStateless")
#TransactionManagement(TransactionManagementType.CONTAINER)
public class ServiceEJBStateless implements ServiceEJBStatelessRemote {
#PersistenceContext(unitName="Test2Jpa2")
EntityManager em;
public ServiceEJBStateless() {
}
#Override
#TransactionAttribute(TransactionAttributeType.REQUIRED)
public long insertUser(User user) {
em.persist(user);
em.merge(user);
return user.getUserId();
}
#Override
#TransactionAttribute(TransactionAttributeType.REQUIRES_NEW)
public User findUser(long id) {
return em.find(User.class, id);
}
This is my persistance.xml
<persistence-unit name="Test2Jpa2" transaction-type="RESOURCE_LOCAL">
<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
<class>com.marcos.domain.User</class>
<properties>
<property name="javax.persistence.jdbc.driver" value="oracle.jdbc.driver.OracleDriver"/>
<property name="javax.persistence.jdbc.url" value="jdbc:oracle:thin:#127.0.0.1:1521:xe"/>
<property name="javax.persistence.jdbc.user" value="hibernatetest"/>
<property name="javax.persistence.jdbc.password" value="pwd123"/>
</properties>
</persistence-unit>
And this is my entity:
#Entity
#Table(name="USERS")
#NamedQuery(name="User.findAll", query="SELECT u FROM User u")
public class User implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#Column(name="USER_ID")
private long userId;
private String fullname;
private String password;
private String username;
public User() {
}
public User(String fm, String pwd, String username) {
this.fullname = fm;
this.password = pwd;
this.username = username;
}
public User(long id, String fm, String pwd, String username) {
this.userId = id;
this.fullname = fm;
this.password = pwd;
this.username = username;
}
public long getUserId() {
return this.userId;
}
public void setUserId(long userId) {
this.userId = userId;
}
public String getFullname() {
return this.fullname;
}
public void setFullname(String fullname) {
this.fullname = fullname;
}
public String getPassword() {
return this.password;
}
public void setPassword(String password) {
this.password = password;
}
public String getUsername() {
return this.username;
}
public void setUsername(String username) {
this.username = username;
}
#Override
public String toString(){
return "Id: "+this.userId+"\n"+
"Name: "+this.fullname+"\n"+
"Username: "+this.username+"\n"+
"Password: "+this.password;
}
