Persist data in associated tables from single screen
Hi All,
I am asking this question second time as I am still not able to fix this problem. I searched for it but could not get the solution.
I have two tables(This is just a test scenario):-
1.) user (user_id,name)
2.) user_phone(user_phone_id,number,user_id)
I want to insert user details and 2 different phone numbers for a user from a single screen.
My screen should look like this:-
Name----------TextBox
Phone 1-------TextBox
Phone 2-------TextBox
Save Button
Entity beans:-
User.java
@Entity
@Table(name = "user")
@Name("user")
public class User implements java.io.Serializable {
private Integer userId;
private String name;
private List<UserPhone> userPhones = new ArrayList<UserPhone>();
public User() {
}
public User(String name, List<UserPhone> userPhones) {
this.name = name;
this.userPhones = userPhones;
}
@Id
@GeneratedValue(strategy = IDENTITY)
@Column(name = "user_id", unique = true, nullable = false)
public Integer getUserId() {
return this.userId;
}
public void setUserId(Integer userId) {
this.userId = userId;
}
@Column(name = "name", length = 20)
@Length(max = 20)
public String getName() {
return this.name;
}
public void setName(String name) {
this.name = name;
}
@OneToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY, mappedBy = "user")
public List<UserPhone> getUserPhones() {
return this.userPhones;
}
public void setUserPhones(List<UserPhone> userPhones) {
this.userPhones = userPhones;
}
}
UserPhone.java
@Entity
@Table(name = "user_phone")
@Name("userPhone")
public class UserPhone implements java.io.Serializable {
private Integer userPhoneId;
private User user;
private String number;
public UserPhone() {
}
public UserPhone(User user, String number) {
this.user = user;
this.number = number;
}
@Id
@GeneratedValue(strategy = IDENTITY)
@Column(name = "user_phone_id", unique = true, nullable = false)
public Integer getUserPhoneId() {
return this.userPhoneId;
}
public void setUserPhoneId(Integer userPhoneId) {
this.userPhoneId = userPhoneId;
}
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "user_id")
public User getUser() {
return this.user;
}
public void setUser(User user) {
this.user = user;
}
@Column(name = "number", length = 20)
@Length(max = 20)
public String getNumber() {
return this.number;
}
public void setNumber(String number) {
this.number = number;
}
}
AddUserAction.java
@In
User user;
public void addUser() {
// implement your business logic here
log.info("addUser.addUser() action called with: #{user.name}");
entityManager.persist(user);
facesMessages.add("addUser #{user.name}");
}
xhtml
<h:form id="addUserForm">
<rich:panel>
<f:facet name="header">addUser</f:facet>
<s:decorate id="nameDecoration" template="layout/edit.xhtml">
<ui:define name="label">Name</ui:define>
<h:inputText id="name" required="true"
value="#{user.name}"/>
</s:decorate>
<s:decorate id="numberDecoration" template="layout/edit.xhtml">
<ui:define name="label">Phone1</ui:define>
<h:inputText id="number" required="true"
value="#{user.userPhones}"/>
</s:decorate>
<s:decorate id="numberDecoration1" template="layout/edit.xhtml">
<ui:define name="label">Phone2</ui:define>
<h:inputText id="number1" required="true"
value="#{user.userPhones}"/>
</s:decorate>
<div style="clear:both"/>
</rich:panel>
<div class="actionButtons">
<h:commandButton id="addUser" value="addUser"
action="#{addUser.addUser}"/>
</div>
</h:form>
I still do not know if seam supports this type of scenario. If it does then what is the right way of doing it and if it doesn't then how do I do it using hibernate.
Can anyone please help me on this with some links.
Any Help would be appreciated.
