How to pass #EmbeddedId in POST json in spring-boot data rest

I have built a REST API using Spring Boot Data REST. I'm using an embeddedId and have also implemented a BackendIdConverter.
Below is my Embeddable class
#Embeddable
public class EmployeeIdentity implements Serializable {
#NotNull
#Size(max = 20)
private String employeeId;
#NotNull
#Size(max = 20)
private String companyId;
public EmployeeIdentity() {}
public EmployeeIdentity(String employeeId, String companyId) {
this.employeeId = employeeId;
this.companyId = companyId;
}
public String getEmployeeId() {
return employeeId;
}
public void setEmployeeId(String employeeId) {
this.employeeId = employeeId;
}
public String getCompanyId() {
return companyId;
}
public void setCompanyId(String companyId) {
this.companyId = companyId;
}
#Override
public boolean equals(Object o) {
if (this == o) return true;
if (o == null || getClass() != o.getClass()) return false;
EmployeeIdentity that = (EmployeeIdentity) o;
if (!employeeId.equals(that.employeeId)) return false;
return companyId.equals(that.companyId);
}
#Override
public int hashCode() {
int result = employeeId.hashCode();
result = 31 * result + companyId.hashCode();
return result;
}
}
Here's my Employee model
#Entity
#Table(name = "employees")
public class Employee {
#EmbeddedId
private EmployeeIdentity id;
#NotNull
#Size(max = 60)
private String name;
#NaturalId
#NotNull
#Email
#Size(max = 60)
private String email;
#Size(max = 15)
#Column(name = "phone_number", unique = true)
private String phoneNumber;
public Employee() {}
public Employee(EmployeeIdentity id, String name, String email, String phoneNumber) {
this.id = id;
this.name = name;
this.email = email;
this.phoneNumber = phoneNumber;
}
public EmployeeIdentity getId() {
return id;
}
public void setId(EmployeeIdentity id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getPhoneNumber() {
return phoneNumber;
}
public void setPhoneNumber(String phoneNumber) {
this.phoneNumber = phoneNumber;
}
}
And to have resource links generated properly using my embedded id instead of a qualified class name
#Component
public class EmployeeIdentityIdConverter implements BackendIdConverter {
#Override
public Serializable fromRequestId(String id, Class<?> aClass) {
String[] parts = id.split("_");
return new EmployeeIdentity(parts[0], parts[1]);
}
#Override
public String toRequestId(Serializable source, Class<?> aClass) {
EmployeeIdentity id = (EmployeeIdentity) source;
return String.format("%s_%s", id.getEmployeeId(), id.getCompanyId());
}
#Override
public boolean supports(Class<?> type) {
return Employee.class.equals(type);
}
}
And here's my repository code
#RepositoryRestResource(collectionResourceRel = "employees", path = "employees")
public interface EmployeeRepository extends PagingAndSortingRepository<Employee, EmployeeIdentity> {
}
This works fine with GET requests but I need to be able to POST. The first thing I noticed that when I do a POST with the json
{
"id": {
"employeeId": "E-267",
"companyId": "D-432"
},
"name": "Spider Man",
"email": "spman#somedomain.com",
"phoneNumber": "+91-476253455"
}
This doesn't work. EmployeeIdentityIdConverter#fromRequestId throws a null pointer exception because the string parameter is null. So I added a null check and return default EmployeeIdentity when id is null. As described by this answer https://stackoverflow.com/a/41061029/4801462
Modified EmployeeIdentityIdConverter#fromRequestId
#Override
public Serializable fromRequestId(String id, Class<?> aClass) {
if (id == null) {
return new EmployeeIdentity();
}
String[] parts = id.split("_");
return new EmployeeIdentity(parts[0], parts[1]);
}
But this raised another problem. My implementations for hashCode and equals now through null pointer exceptions since the default constructor was used and the employeeId and companyId are null.
In an attempt to fix this, I gave default values to employeeId and companyId
**Modified Employee#Employee() constructor*
public Employee() {
this.employeeId = "";
this.companyId = "";
}
NOTE
I am not even sure of what I was doing above. I was just trying to fix the small problems as they occurred.
By the way if you guessed this didn't work then you're right. While I didn't get an error and the request was successful, I didn't get the behavior I expected. A new entry was created with empty employeeId and companyId.
How do make POST to REST API whose model uses #EmbeddedId with spring boot data rest?

Here is an other solution. (Still not perfect though.)
Expose the id for your Employee class:
#Configuration
protected class MyRepositoryRestConfigurer implements RepositoryRestConfigurer {
#Override
public void configureRepositoryRestConfiguration(RepositoryRestConfiguration config) {
config.exposeIdsFor(ThemeMessage.class);
}
}
Add the following line to your converter (during POST requests the id will be null):
#Override
public Serializable fromRequestId(String id, Class<?> aClass) {
if(id==null) {
return null;
}
String[] parts = id.split("_");
return new EmployeeIdentity(parts[0], parts[1]);
}
The following POST request then will work:
{
"id": {
"employeeId": "E-267",
"companyId": "D-432"
},
"name": "Spider Man",
"email": "spman#somedomain.com",
"phoneNumber": "+91-476253455"
}
However, the id field will be exposed in all of the responses. But maybe it's not a real problem, because when you use a composite id it usually means that the id is not only an abstract identifier, but its parts have meaningful content which should appear in the entity body.
Actually, I'm thinking of adding these lines to my own code too .... :)

I had a similar problem and I couldn't find a solution for creating new entities via the POST /entities endpoint.
However, you can also create a new entity via PUT /entities/{newId} endpoint. And the converter works fine for these endpoints.
I also completely denied the POST endpoint avoiding the 500 responses:
#PostMapping(value = "/themeMessages")
public ResponseEntity<Void> postThemeMessage() {
return new ResponseEntity<>(HttpStatus.METHOD_NOT_ALLOWED);
}

I am using import org.springframework.transaction.annotation.Transactional; for transnational in DAO. Also I can not use #PersistenceContext(type=PersistenceContextType.EXTENDED) and fetch type Eager because I get error of Maximum stack size exceeded

I solved it by using the #JsonBackReference on OneToMany relationship. The problem is with the Serialization and Deserialization.
" the property annotated with #JsonManagedReference annotation is handled normally (serialized normally, no special handling for deserialization) and the property annotated with #JsonBackReference annotation is not serialized; and during deserialization, its value is set to instance that has the "managed" (forward) link."

You should do one or both of the following:
1) Move the #Transactional from DAO to Service. Thats a good idea in general as usually are still processing the result entities in some way on that layer.
2) Fetch the dependencies in the queries explicitly:
select ct FROM City as ct inner join fetch ct.states s ORDER BY ct.id

Spring data Mongo DB retrieving data : #Document VO returns null

I am trying to retrieve data from mongodb via spring framework.
At first I made return type Map<String, Object>, but I decided to change to User value object.
Below is the class for User VO
#Document(collection = "user")
public class User {
#Id
#Field(value="id")
private String id;
#Field(value="name")
private String name;
#Field(value="password")
private String password;
#Field(value="professional")
private String professional;
#Field(value="email")
private String email;
#Field(value="gravatar")
private String gravatar;
#PersistenceConstructor
public User(String id, String name, String password, String professional, String email, String gravatar) {
super();
this.id = id;
this.name = name;
this.password = password;
this.professional = professional;
this.email = email;
this.gravatar = gravatar;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getProfessional() {
return professional;
}
public void setProfessional(String professional) {
this.professional = professional;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getGravatar() {
return gravatar;
}
public void setGravatar(String gravatar) {
this.gravatar = gravatar;
}
};
and Here is #repository to retrieve data
#Repository
public class MongoMemberDao implements CommonDao<String, Map<String, Object>, Exception> {
#Autowired
MongoTemplate template;
final String COLLECTION_NAME = "user";
#SuppressWarnings("unchecked")
#Override
public Map<String, Object> read(String key) throws Exception {
Query findQuery = new Query();
findQuery.addCriteria(Criteria.where("id").is(key));
return template.findOne(findQuery, Map.class, COLLECTION_NAME);
}
public User readByDocument(String id) throws Exception {
Query findOneQuery = new Query();
findOneQuery.addCriteria(Criteria.where("id").is(id));
return template.findOne(findOneQuery, User.class, COLLECTION_NAME);
}
};
read method returns fine, but readByDocument does not(returns null not User instance). I read official document. But I do not get any clue of it.
FYI, The parameter Query looks same for both.
Query: { "id" : "system"}, Fields: null, Sort: null
I want to know why readByDocument returns null
Thanks.
---- Edit
Follow is my Database Config
#Configuration
public class MongoConfig extends AbstractMongoConfiguration {
private final String MONGO_URL = "127.0.0.1";
private final Integer MONGO_PORT = 27017;
#Override
protected String getDatabaseName() {
return "tfarm";
}
#Override
// #Bean
public Mongo mongo() throws Exception {
return new MongoClient(MONGO_URL, MONGO_PORT);
}
}
And I added this to WebApplictaionInitializer implement.

For current solution
I found follow on official site
A field annotated with #Id (org.springframework.data.annotation.Id)
will be mapped to the _id field.
A field without an annotation but named id will be mapped to the _id
field.
The default field name for identifiers is _id and can be customized
via the #Field annotation.
So I changed my VO like...
#Document(collection = "user")
public class User {
#Id
private ObjectId _id;
#Field(value="id")
private String id;
#Field(value="name")
private String name;
#Field(value="password")
private String password;
#Field(value="professional")
private String professional;
#Field(value="email")
private String email;
#Field(value="gravatar")
private String gravatar;
#PersistenceConstructor
public User(String id, String name, String password, String professional, String email, String gravatar) {
super();
this.id = id;
this.name = name;
this.password = password;
this.professional = professional;
this.email = email;
this.gravatar = gravatar;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public ObjectId get_id() {
return _id;
}
public void set_id(ObjectId _id) {
this._id = _id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getProfessional() {
return professional;
}
public void setProfessional(String professional) {
this.professional = professional;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getGravatar() {
return gravatar;
}
public void setGravatar(String gravatar) {
this.gravatar = gravatar;
}
};
Added ObjectId. In alternative, just removing #Id annotation works fine too. However
#Id
#Field(value="id")
String id;
will not work. Thanks for help.

How to make date time field readable after getting response using RestFul webservice

I am building a webapp using Restful webservice using angularJs + spring. Can anybody tell how to make date field readable in the UI ? Also, I am not getting the last field values that is 'STATUS'. Below is the code for the same.

moment is pretty awesome for formatting datetime
Example for your case:
Let's say the datetime looks like 2015-11-11T22:21:37+00:00. Obviously this does not look very readable. We can change it to something better by making a moment object and using the format function.
moment(2015-11-11T22:21:37+00:00).format("MM/DD/YYYY") would output 11/11/2015
