I'm using Spring, Hibernate and PostgreSQL . I want to save the object in database which comes from jsp page. But it throws NullPointerException. I use sequence generator for auto ncrement and created a sequence called emp_id_seq in PostgreSQL . I print the object for finding the problem, it shows
Employee [id=null, firstName=vara, lastName=raj, address=abc, dob=Tue Jun 13 00:00:00 IST 2017, nic=154184125V, email=abc#xyz.com, companyId=1, departmentId=4]

Check your Database and Check the datatype of the Id if it's int you can't send long

When I call the AddUser Request method, this Exception is triggered, I can't find the reason why values are not set to the user Object when the email adress is not found, All the classes are annotated woth their Stereotypes, the user
Bean is autowired, I haven't declared a new Operator.
Would you clarify the cause behind this Exception.
Thank you
I am trying to login but unable to login because findOne query fails in DAOimplementation. I put series of system.out.println to see where does things go wrong.
and I get this
email: abcdef Password : 123123
email2: abcdef Password2: 123123
check 1
check 2
for some reason program wont reach to check 3, check 4 and inside if condition where user != null.
I tried mongoTemplate, mongoOperations, using addCriteria without criteria but no luck.

Use proper Java (Beans) naming conventions:
CamelCase with first letter lowercase:
public User(String id, long userId, String firstname, String lastname, String email, String password, String role, long countryCode, long mobileNumber, String city, String address)
{
super();
this.id = id;
this.userId = userId;
this.firstname = firstname;
this.lastname = lastname;
this.email = email;
this.password = password;
this.role = role;
this.countryCode = countryCode;
this.mobileNumber = mobileNumber;
this.city = city;
this.address = address;
}
Getter and Setter should be the field name with the first letter upper case and prefixed with get or set if present.
Properties referenced in queries/Strings are the same as the field name.
Note: There are some defiations from the actual Java Beans specification, e.g. the option to not have a default constructor.
I am working with Spring Data JPA and an MySQL database for a records management system. Below are two entities that I have modeled and I am trying to persist a Policy record to the database:
Policy Entity:
public class Policy {
private String policyNumber;
private String policyName;
private Steward steward;
private PolicyHolder policyHolder;
#Id
#Column(length = 30)
public String getPolicyNumber() {
return policyNumber;
}
public void setPolicyNumber(String policyNumber) {
this.policyNumber = policyNumber;
}
#Column(length = 80)
public String getPolicyName() {
return policyName;
}
public void setPolicyName(String policyName) {
this.policyName = policyName;
}
#OneToOne(cascade = ALL, mappedBy = "policy", orphanRemoval = true, optional = false)
public PolicyHolder getPolicyHolder() {
return policyHolder;
}
}
PolicyHolder Entity:
#Entity
public class PolicyHolder extends PolicyMember {
private Policy policy;
public PolicyHolder() {
super();
}
#OneToOne
#JoinColumn(name = "policy_policyNumber", referencedColumnName = "policyNumber")
public Policy getPolicy() {
return policy;
}
public void setPolicy(Policy policy) {
this.policy = policy;
}
#Override
public String toString() {
return "PolicyHolder{" +
"policy=" + policy +
"} " + super.toString();
}
}
PolicyMember Entity:
#Entity
public abstract class PolicyMember {
private CompositePolicyMemberPK policyMemberId;
private String firstname;
private String surname;
private LocalDate dateOfDeath;
private LocalDate dateOfBirth;
private MemberStatus status;
private BillingStatus billingStatus;
private String nationalId;
private LocalDateTime creationDate;
private Gender gender;
private String msisdn;
private LocalDate closureDate;
private String createdBy;
private String memberType;
private PackageBenefit packageBenefit;
private List<DependantTransferRequest> transferRequests;
#EmbeddedId
public CompositePolicyMemberPK getPolicyMemberId() {
return policyMemberId;
}
public void setPolicyMemberId(CompositePolicyMemberPK policyMemberId) {
this.policyMemberId = policyMemberId;
}
#Column(length = 50)
public String getFirstname() {
return firstname;
}
public void setFirstname(String firstname) {
this.firstname = firstname;
}
#Column(length = 50)
public String getSurname() {
return surname;
}
public void setSurname(String surname) {
this.surname = surname;
}
#Convert(converter = MemberStatusConverter.class)
public MemberStatus getStatus() {
return status;
}
public void setStatus(MemberStatus status) {
this.status = status;
}
#Convert(converter = BillingStatusConverter.class)
public BillingStatus getBillingStatus() {
return billingStatus;
}
public void setBillingStatus(BillingStatus billingStatus) {
this.billingStatus = billingStatus;
}
#Column(length = 20)
public String getNationalId() {
return nationalId;
}
public void setNationalId(String nationalId) {
this.nationalId = nationalId;
}
#Enumerated(EnumType.STRING)
public Gender getGender() {
return gender;
}
public void setGender(Gender gender) {
this.gender = gender;
}
#Column(length = 15)
public String getMsisdn() {
return msisdn;
}
public void setMsisdn(String msisdn) {
this.msisdn = msisdn;
}
#Column(length = 50)
public String getCreatedBy() {
return createdBy;
}
public void setCreatedBy(String createdBy) {
this.createdBy = createdBy;
}
#Column(name = "memberType", insertable = false, updatable = false)
public String getMemberType() {
return memberType;
}
public void setMemberType(String memberType) {
this.memberType = memberType;
}
#OneToOne(mappedBy = "policyMember", optional = false, cascade = CascadeType.ALL)
public PackageBenefit getPackageBenefit() {
return packageBenefit;
}
public void setPackageBenefit(PackageBenefit packageBenefit) {
this.packageBenefit = packageBenefit;
}
public LocalDate getDateOfDeath() {
return dateOfDeath;
}
public void setDateOfDeath(LocalDate dateOfDeath) {
this.dateOfDeath = dateOfDeath;
}
public LocalDate getDateOfBirth() {
return dateOfBirth;
}
public void setDateOfBirth(LocalDate dateOfBirth) {
this.dateOfBirth = dateOfBirth;
}
public LocalDate getClosureDate() {
return closureDate;
}
public void setClosureDate(LocalDate closureDate) {
this.closureDate = closureDate;
}
public LocalDateTime getCreationDate() {
return creationDate;
}
public void setCreationDate(LocalDateTime creationDate) {
this.creationDate = creationDate;
}
#OneToMany(orphanRemoval = true, mappedBy = "dependantToTransfer")
public List<DependantTransferRequest> getTransferRequests() {
return transferRequests;
}
public void setTransferRequests(List<DependantTransferRequest> transferRequests) {
this.transferRequests = transferRequests;
}
}
Composite Key:
#Embeddable
public class CompositePolicyMemberPK implements Serializable {
private String policyNumber;
private String suffixNumber;
private static final long serialVersionUID = 1L;
public CompositePolicyMemberPK(String policyNumber, String suffixNumber) {
super();
this.policyNumber = policyNumber;
this.suffixNumber = suffixNumber;
}
public CompositePolicyMemberPK() {
super();
}
#Column(length = 30)
public String getPolicyNumber() {
return this.policyNumber;
}
public void setPolicyNumber(String policyNumber) {
this.policyNumber = policyNumber;
}
#Column(length = 2)
public String getSuffixNumber() {
return this.suffixNumber;
}
public void setSuffixNumber(String suffixNumber) {
this.suffixNumber = suffixNumber;
}
#Override
public boolean equals(Object o) {
if (o == this) {
return true;
}
if (!(o instanceof CompositePolicyMemberPK)) {
return false;
}
CompositePolicyMemberPK other = (CompositePolicyMemberPK) o;
return (getPolicyNumber() == null ? other.getPolicyNumber() == null : getPolicyNumber().equals(other.getPolicyNumber())) && (getSuffixNumber() == null ? other.getSuffixNumber() == null : getSuffixNumber().equals(other.getSuffixNumber()));
}
#Override
public int hashCode() {
final int prime = 31;
int result = 1;
result = prime * result + (getPolicyNumber() == null ? 0 : getPolicyNumber().hashCode());
result = prime * result + (getSuffixNumber() == null ? 0 : getSuffixNumber().hashCode());
return result;
}
#Override
public String toString() {
return this.getPolicyNumber() + "-" + this.getSuffixNumber();
}
}
The code that is responsible for persisiting the policy is as follows:
public Subscriber addMemberToSteward(Long stewardId, Subscriber subscriber) {
Steward steward = this.findStewardById(stewardId);
if(steward == null){
throw new EcosureException(String.format("No steward found with id '%s'.",stewardId));
}
final BillingStatus billingStatus = BillingStatus.REG_IN_PROGRESS;
final MemberStatus memberStatus = MemberStatus.NEW;
final ProductPackage product = productService.findPackageById(subscriber.getProductPackageId());
subscriber.setNationalId(nationalIDNumberUtils.formatIdNumber(subscriber.getNationalId()));
final PolicyHolder policyHolder = convertToPolicyHolder(subscriber, product, billingStatus, memberStatus);
Policy policy = getPolicyFromSubscriberInfo(subscriber, policyHolder);
policy.setSteward(steward);
policy.setStatus(PolicyStatus.NEW);
System.out.println("Policy Holder" + policyHolder);
policyRepository.save(policy);
return subscriber;
}
The getPolicyFromSubscriberInfo method is below:
private Policy getPolicyFromSubscriberInfo(final Subscriber subscriberInfo, final PolicyHolder policyHolder) throws {
final Policy policy = new Policy();
policy.setMsisdn(subscriberInfo.getMsisdn());
policy.setPolicyNumber(policyNumberGenerator.getNextPolicyNumber());
policy.setPolicyName(policyHolder.getFirstname() + " " + policyHolder.getSurname());
policyHolder.setPolicy(policy);
CompositePolicyMemberPK policyMemberId = new CompositePolicyMemberPK();
policyMemberId.setPolicyNumber(policy.getPolicyNumber());
policyMemberId.setSuffixNumber(policyNumberGenerator.getNextSuffix(policy.getPolicyNumber(),true));
policyHolder.setPolicyMemberId(policyMemberId);
policy.setPolicyHolder(policyHolder);
return policy;
}
The PolicyRepository is shown below:
public interface PolicyRepository extends JpaRepository<Policy, String> {
}
When I try to persist a Policy entity I am getting the error below:

Can anyone please assist me in identifying where I am going wrong.
In JSP I have simple foreach, which should display the information from two tables. First table "Organizations" as "country" parameter keeps id of country as a foreign key to another table "Countries".
How can I show country name in this foreach, which keeps in “Organizations" as id of country?
<c:forEach items=“${organizations}" var=“organization">
<c:url var="edit" value="/edit/${organization.id}" />
<c:url var="remove" value="/remove/${organization.id}" />
<tr>
<td><c:out value="${organization.name}" /></td>
<td><c:out value="${organization.country}" /></td> // In this line
<td><c:out value="${organization.address}" /></td>
<td><c:out value="${organization.phone}" /></td>
<td><c:out value="${organization.market_cap}" /></td>
<td valign = "top">Edit</td>
<td valign = "top">Remove</td>
</tr>
</c:forEach>
Tables:
CREATE TABLE IF NOT EXISTS Organization (id int auto_increment , name varchar(255), country int, address varchar(255), phone varchar(255)primary key(id), foreign key (country) references public.country(id_country));
CREATE TABLE IF NOT EXISTS Country (id_country int auto_increment , name varchar(255), primary key(id_country));
Model, Organization:
import javax.persistence.*;
#Entity
public class Organization {
#Id
#GeneratedValue
private Integer id;
private String name;
private Integer country;
private String address;

this.id = id;

public void setIsocode(String isocode) {
this.isocode = isocode;

}

Your model is inadequate for that kind operation. What you need to do is:
Your model must change:
import javax.persistence.*;
#Entity
public class Organization {
#Id
#GeneratedValue
private Integer id;
private String name;
//This will load automatically when you load your Organization entity.
#OneToOne(cascade=CascadeType.ALL,fetch=FetchType.EAGER)
#JoinColumn(name="country")
private Country country;
private String address;
private String phone;
private Long market_cap;
public Organization(Integer id, String name, Country country, String address, String phone, Long market_cap) {
this.id = id;
this.name = name;
this.country = country;
this.address = address;
this.phone = phone;
this.market_cap = market_cap;
}
public Organization() {
}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Country getCountry() {
return country;
}
public void setCountry(Country country) {
this.country = country;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
public String getPhone() {
return phone;
}
public void setPhone(String phone) {
this.phone = phone;
}
public Long getMarket_cap() {
return market_cap;
}
public void setMarketCap(Long market_cap) {
this.market_cap = market_cap;
}
}
and in you view in that case jsp:
<c:forEach items=“${organizations}" var=“organization">
<c:url var="edit" value="/edit/${organization.id}" />
<c:url var="remove" value="/remove/${organization.id}" />
<tr>
<td><c:out value="${organization.name}" /></td>
<td><c:out value="${organization.country.name}" /></td> //Should do the trick
<td><c:out value="${organization.address}" /></td>
<td><c:out value="${organization.phone}" /></td>
<td><c:out value="${organization.market_cap}" /></td>
<td valign = "top">Edit</td>
<td valign = "top">Remove</td>
</tr>
</c:forEach>
