its my first time crating api in spring boot, i'm trying to create transaction api. when i'm running the application i'm getting this error
Description:
Parameter 0 of constructor in TransactionService.transactionService.modal.TransactionRequest required a bean of type 'int' that could not be found.
Action:
Consider defining a bean of type 'int' in your configuration.
Modal package:
TransactionEntity
#Getter
#Setter
#Builder
#Entity
public class TransactionEntity {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private int transactionId;
#NotNull
#Column(unique = true)
private UUID externalId;
#NotNull
private int userId;
#NotNull
private int merchantId;
#NotNull
private int clientReferenceId;
#NotNull
private double amount;
#Enumerated(EnumType.STRING)
#NotNull
private TransactionStatus status;
#NotNull
private String createdBy;
private String updatedBy;
#NotNull
private LocalDateTime createdAt;
#NotNull
private LocalDateTime updatedAt;
}
TransactionRequest
#Component
#Data
#Builder
public class TransactionRequest {
private int userId;
private int merchantId;
private int clientReferenceId;
private double amount;
private String createdBy;
}
TransactionResponse
#Component
#Data
#Builder
public class TransactionResponse {
private int userId;
private int merchantId;
private int clientReferenceId;
private double amount;
private LocalDateTime createdAt;
private TransactionStatus status;
}
TransactionDao
#Component
// Dao class
public class TransactionDao {
#Autowired
TransactionRepository transactionRepository;
TransactionEntity transactionEntity;
public TransactionResponse createTransaction(TransactionRequest transactionRequest){
LocalDateTime cuurentTime = LocalDateTime.now();
transactionEntity.builder().userId(transactionRequest.getUserId())
.merchantId(transactionRequest.getMerchantId())
.clientReferenceId(transactionRequest.getClientReferenceId())
.amount(transactionRequest.getAmount())
.createdBy(transactionRequest.getCreatedBy())
.createdAt(cuurentTime)
.updatedAt(cuurentTime)
.externalId(UUID.randomUUID())
.status(TransactionStatus.CREATED);
transactionRepository.save(transactionEntity);
return TransactionResponse.builder().status(transactionEntity.getStatus())
.createdAt(transactionEntity.getCreatedAt()).build();
}
}
TransactionService
#Service
public class TransactoinService {
#Autowired
public TransactionDao transactionDao;
public TransactionResponse createTransaction(TransactionRequest transactionRequest){
return transactionDao.createTransaction(transactionRequest);
}
}
TransactionController
#RestController
public class TransactionController {
#Autowired
TransactoinService transactoinService;
#PostMapping
TransactionResponse createTransaction(#RequestBody TransactionRequest transactionRequest){
return transactoinService.createTransaction(transactionRequest);
}
}
The TransactionRequest is annotated as #Component so spring boot autoscan will try to create a #Bean out that class.
It is also annotated with #Data so at the time of creating the bean Spring boot is trying to inject other beans as arguments into the all args constructor, and it is not finding an "int" bean to inject into the constructor.
I am guessing that the transaction response should not be a #Component or at least not a Singleton bean.
You should not create your POJO classes as a Spring Bean. Remove #Component annotation in your TransactionRequest and TransactionResponse POJO classes.

my auditing works pretty nice but need to change create listener in that way to obtain null values in first update.
#MappedSuperclass
#Getter
#Setter
#ToString
#EntityListeners(AuditingEntityListener.class)
public abstract class AbstractEntity{
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private long id;
#Version
private int version;
#CreatedBy
private String createdBy;
#LastModifiedBy
private String updatedBy;
#CreatedDate
private LocalDateTime createdAt;
#LastModifiedDate
private LocalDateTime updatedAt;
}
#Entity
#AllArgsConstructor
#NoArgsConstructor
#Getter
#Setter
#ToString
public class TestProfile extends AbstractEntity{
private String username;
}
Right now during create entity, the "updatedBy" and "updatedAt" is also fullfilled with duplicated values from "createdBy" and "createdAt". Should I change my default implementation to #PrePersist and #PreUpdate?
Here is my JpaConfig
#Configuration
#EnableJpaAuditing(auditorAwareRef = "auditorAware")
public class AuditingConfig`enter code here` {
#Bean
public AuditorAware<String> auditorAware() {
return () -> Optional.of(((UserDetails) SecurityContextHolder
.getContext().getAuthentication().getPrincipal()).getUsername());
}
}
How do I make my pojo classes as components, so that I can autowire wherever I want? What will be the steps to do? Is this the right way for a spring boot application?
In my application iam using lombok for getters and setters. Here is my pojo:
#Accessors(chain = true)
#NoArgsConstructor
#Getter
#Setter
#ToString
#JsonIgnoreProperties(ignoreUnknown = true)
#SuppressWarnings("all")
public class Qei implements Serializable {
private static final long serialVersionUID = 2902444063726917000L;
private Integer qeiMasterId;
private String qeiId;
#JsonFormat(shape = JsonFormat.Shape.STRING, pattern = NMTCConstants.DATEFORMAT)
private Date originalDate;
private BigDecimal amount;
#JsonFormat(shape = JsonFormat.Shape.STRING, pattern = NMTCConstants.DATEFORMAT)
private Date complianceEndDate;
private BigDecimal perAllocAgreementPercent;
private BigDecimal minRequiredPercent;
private Integer allocationYear;
private DealDetail dealDetail;// other class
private List<Qlici> qliciInfo;//other class
}
In order to use this class, can it be spring component?
I have a super Entity class like this:
#Getter
#Setter
#NoArgsConstructor
public class GenericEntity {
#Id
private Long id;
#JsonIgnore
#CreatedBy
private Long createdBy;
#JsonIgnore
#CreatedDate
private Long createdDate;
#JsonIgnore
#LastModifiedBy
private Long updatedBy;
#JsonIgnore
#LastModifiedDate
private Long updatedDate;
#JsonIgnore
#Version
private Integer version = 0;
}
and a Role class extends from GenericEntity like this:
#Getter
#Setter
#NoArgsConstructor
public class Role extends GenericEntity {
private String name;
private String desc;
private Integer sort;
}
And after that I have interface RoleRepo like this:
#Repository
public interface RoleRepo extends ReactiveCrudRepository<Role, Long>;
In Router function, I have 2 handler methods
private Mono<ServerResponse> findAllHandler(ServerRequest request) {
return ok()
.contentType(MediaType.APPLICATION_JSON)
.body(roleRepo.findAll(), Role.class);
}
private Mono<ServerResponse> saveOrUpdateHandler(ServerRequest request) {
return ok()
.contentType(MediaType.APPLICATION_JSON_UTF8)
.body(request.bodyToMono(Role.class).flatMap(role -> {
return roleRepo.save(role);
}), Role.class);
}
The method findAllHandler works fine, but the saveOrUpdateHandler throw exception like this:
java.lang.IllegalStateException: Required identifier property not found for class org.sky.entity.system.Role!
at org.springframework.data.mapping.PersistentEntity.getRequiredIdProperty(PersistentEntity.java:105) ~[spring-data-commons-2.2.0.M2.jar:2.2.0.M2]
at org.springframework.data.r2dbc.function.convert.MappingR2dbcConverter.lambda$populateIdIfNecessary$0(MappingR2dbcConverter.java:85) ~[spring-data-r2dbc-1.0.0.M1.jar:1.0.0.M1]
But when I move
#Id
private Long id;
from GenericEntity class to Role class, the two methods work fine.
Are there any Annations #MappedSuperclass/JPA in Spring Reactive Data like that
I wish the id field in GenericEntity for all extends class
Thanks for your help
Sorry, my English so bad
I had a similar problem and after some search, I didn't find an answer to your question, so I test it by writing code and the answer is spring data R2DBC doesn't need #Mappedsuperclass. it aggregates Role class properties with Generic class properties and then inserts all into the role table without the need to use any annotation.
I have used the #CreatedBy, #CreatedDate, #LastModifiedBy, and #LastModifiedDate annotation on their respective fields. By using #MappedSuperclass,#EntityListeners i able to persist above columns.
But this is not working for the below case:
#MappedSuperclass
#EntityListeners(AuditingEntityListener.class)
public abstract class Auditable<U> {
#CreatedBy
protected U createdBy;
#CreatedDate
#Temporal(TIMESTAMP)
protected Date creationDate;
#LastModifiedBy
protected U lastModifiedBy;
#LastModifiedDate
#Temporal(TIMESTAMP)
protected Date lastModifiedDate;
}
#Entity
#Table(name = "tabel1")
#PrimaryKeyJoinColumn(name = "ID")
class A extends B {
#Column(name = "NAME1", nullable = false)
private String name1;
#Column(name = "CONTENT1", nullable = false)
private String content1;
}
#Entity
#Table(name = "tabel2")
public abstract class B extends Auditable{
#Id
#GeneratedValue
#Column(name = "ID", nullable = false)
private int id;
#Column(name = "NAME", nullable = false)
private String name;
#Column(name = "CONTENT", nullable = false)
private String content;
}
AuditorAwareImpl.java
public class AuditorAwareImpl implements AuditorAware<String>
{
#Override
public Optional<String> getCurrentAuditor()
{
return Optional.ofNullable("Saravanan");
}
}
JpaAuditConfiguration.java
#Configuration
#EnableJpaAuditing(auditorAwareRef = "auditorProvider")
public class JpaAuditConfiguration
{
#Bean
public AuditorAware<String> auditorProvider()
{
return new AuditorAwareImpl();
}
}
In the case, Entity B is populated with audit columns. But Entity A is not. Is there a way to populate Entity A or did i missed anything here..??
I added #Entity annotation to your classes:
#Entity
public class A extends B {
#Id
#GeneratedValue
private Integer id;
private String name;
private String content;
}
#Entity
public class B extends Auditable<String> {
#Id
#GeneratedValue
private Integer id;
private String name;
private String content;
}
Persistence config class (for Spring Boot):
#Configuration
#EnableJpaAuditing
public class PersistenceConfig {
}
Everything works perfectly!
I am running Spring Boot 1.5.1 with Spring Data JPA repositories. I have added a method to my User repository that makes use of JPA projections(UserProfile) which works great. I now wish to cache the results of that method in my Service layer which should return a result of type Page< UserProfile > as shown
The JPA Projection.
public interface UserProfile extends Serializable {
long getId();
#Value("#{target.firstname} #{target.othernames}")
String getFullName();
String getFirstname();
String getOthernames();
String getGender();
String getEnabled();
#Value("#{T(System).currentTimeMillis()-target.birthday.getTime()}")
long getBirthday();
}
The User Entity.
#Entity
#Cacheable(true)
#Cache(usage = CacheConcurrencyStrategy.READ_WRITE)
public class User implements Serializable {
private static final long serialVersionUID = 6756059251848061768L;
#Id
#GeneratedValue(strategy=GenerationType.AUTO)
private long id;
#Column
private String firstname;
#Column
private String othernames;
#Column
private String gender;
#Column
private String photoname;
#Column
private Date birthday;
#Column
private String username;
#Column
private Boolean enabled;
#Column
private String password;
#ElementCollection
private Map<String,String> phonenumbers = new HashMap<String,String>(0);
#JsonBackReference
#OneToMany(cascade = CascadeType.ALL, orphanRemoval=true)
#Cache(usage = CacheConcurrencyStrategy.READ_WRITE)
private List<Address> addresses = new ArrayList<Address>(0);
//Omitted Getters and Setters
#Override
public int hashCode() {...}
#Override
public boolean equals(Object obj) {...}
}
The User repository.
#Repository
public interface UserRepository extends JpaRepository<User, Long> {
public Page<UserProfile> findAllUserProfilesBy(Pageable pageable);
}
The User service implementation.
#Service
#Transactional(readOnly=true)
public class UserServiceImpl implements UserService {
#Autowired
UserRepository UserRepository;
#Override
#Cacheable("users")
public Page<UserProfile> findAllUserProfiles(Pageable pageable) {
//simulateSlowService();
return UserRepository.findAllUserProfilesBy(pageable);
}
}
However I get the following exception when the service method gets called.
java.lang.RuntimeException: Class org.springframework.data.projection.DefaultMethodInvokingMethodInterceptor does not implement Serializable or externalizable
How should I go about caching the result of the service method?
Any help is greatly appreciated.
