Every column in my users table can take a null, and so it is allowed to save a record in this state. I checked this by executing the equivalent query against the databse manually.
Does anyone have any ideas?

One glaring error is that the constructor in User used to register a user doesn't assign the username, email, password parameters passed in.

How to show alias column in spring data jpa using native query?

I want to show it in my response distance field, but I am not able to do it please help.
Here is my repo class in alias name (distance) I need to attach this distance column with my list of user results.

I need to add Distance column in my response
I need to show calculated distance in response

#Transient annotation is used to mark a field to be transient for the mapping framework, which means the field marked with #Transient is ignored by mapping framework and the field not mapped to any database column.
Therefore try representing the distance property with #Formula annotation, and apply the distance calculation so that we can obtain the calculated value(I can see that you are calculating the distance based upon the image you have shared).
With #Formula, we can call native database functions and stored procedures and basically do anything that does not break the syntax of an SQL select clause for this field.

Can you not create a mapping between Client and Role? Either a #OneToMany or #ManyToMany? If so then you dont need to write any sql and could do this with a simple JPA Query method http://docs.spring.io/spring-data/jpa/docs/current/reference/html/#repositories.query-methods.query-creation

Retrieving multi select list values to insert into database in struts

I am developing an Online Book Library application in struts...
I have a user form wherein user will enter his details like first name,last name etc and also there would be a books list where he will select some books that he wants..an d later on I want to insert those details into 2 tables..i.e user details in obl_users and and books that user select in users_books.
I used the below code for the list ..
<%
if(request.getAttribute("booksNameList") != null) {
%>
<html:select property="displayBooks" multiple="true" size="5">
<logic:iterate id="booksNameList" name="booksNameList" scope="request">
<html:option value="${booksNameList.bookId}" ><bean:write name="booksNameList" property="longTitle" /></html:option>
</logic:iterate>
</html:select>
<%
}
%>
Initially when user request form then the form will have pre populated list will all the books name in database..I am not sure about the code that i wrote to get book id in the value part of i.e value="${booksNameList.bookId}" ..
In my addUser() I want to iterate through the user selected books like this..
for (int i = 0; i < selectedBooks.length; i++) {
//insertBooks.setInt(1, generatedKeys.getInt(1));
//insertBooks.setInt(2, Integer.parseInt(selected[i]));
//insertBooks.addBatch();
}
but for that how to get the user selected books..
Here is my user.java
public class User extends ActionForm {
private int userId;
private String firstName;
private String lastName;
private String middleName;
private String username;
private String password;
private String contactNumber;
private String membershipNumber;
private String role;
private String email;
private String address;
private String comments;
private String dateOfBirth;
private int oblStatus;
private String createdDate;
private String updatedDate;
private String createdBy;
private String updatedBy;
private String displayBooks;
public int getUserId() {
return userId;
}
public void setUserId(int userId) {
this.userId = userId;
}
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
public String getMiddleName() {
return middleName;
}
public void setMiddleName(String middleName) {
this.middleName = middleName;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getContactNumber() {
return contactNumber;
}
public void setContactNumber(String contactNumber) {
this.contactNumber = contactNumber;
}
public String getMembershipNumber() {
return membershipNumber;
}
public void setMembershipNumber(String membershipNumber) {
this.membershipNumber = membershipNumber;
}
public String getRole() {
return role;
}
public void setRole(String role) {
this.role = role;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
public String getComments() {
return comments;
}
public void setComments(String comments) {
this.comments = comments;
}
public String getDateOfBirth() {
return dateOfBirth;
}
public void setDateOfBirth(String dateOfBirth) {
this.dateOfBirth = dateOfBirth;
}
public int getOblStatus() {
return oblStatus;
}
public void setOblStatus(int oblStatus) {
this.oblStatus = oblStatus;
}
public String getCreatedDate() {
return createdDate;
}
public void setCreatedDate(String createdDate) {
this.createdDate = createdDate;
}
public String getUpdatedDate() {
return updatedDate;
}
public void setUpdatedDate(String updatedDate) {
this.updatedDate = updatedDate;
}
public String getCreatedBy() {
return createdBy;
}
public void setCreatedBy(String createdBy) {
this.createdBy = createdBy;
}
public String getUpdatedBy() {
return updatedBy;
}
public void setUpdatedBy(String updatedBy) {
this.updatedBy = updatedBy;
}
public String getDisplayBooks() {
return displayBooks;
}
public void setDisplayBooks(String displayBooks) {
this.displayBooks = displayBooks;
}
}
book bean class:
private String bookId;
private String longTitle;
private String shortTitle;
private String isbn;
private String dateOfPublication;
private String noOfPages;
private String boundType;
private String dvdAvailability;
private String noOfAvailableCopies;
private int oblStatus;
private String createdDate;
private String updatedDate;
private String createdBy;
private String updatedBy;
private String displayAuthors;
private int[] authorIds;
please guide me...i am totally new to struts

You have to put "displayBooks" property as a String array like;
private String[] displayBooks;
Since you want to select multiple values on the form, Array or ArrayList can be the only better option to use.
