As mentioned in spring data couchbase reference guide, i am trying to enable optimistic locking feature using #Version annotation. My expectation is couchbase will populate version field when a doucument is mutated. But seems like it is not populating the version field. its always 0. Following is my Pojo, and using crudRepository to save the document. when i update i try to send version as 1 to simulate optimitic locking exception. But i didn't get any exception the update went fine. Since the documentation is not helping much, i could not proceed further. Any help will be greatly appreciated?
#Document
public class Project extends BusinessEntity {
private static final long serialVersionUID = 1665165729053936288L;
#NotNull
#Field
private String name;
#Field
private String description;
#Version
private long version;
public Project() {
}
public Project(String name) {
this.name = name;
}
public Project(String name, String description) {
super();
this.name = name;
this.description = description;
}
/**
* #return the name
*/
public String getName() {
return name;
}
/**
* #param name the name to set
*/
public void setName(String name) {
this.name = name;
}
/**
* #return the description
*/
public String getDescription() {
return description;
}
/**
* #param description the description to set
*/
public void setDescription(String description) {
this.description = description;
}
/**
* #return the version
*/
public long getVersion() {
return version;
}
/**
* #param version the version to set
*/
public void setVersion(long version) {
this.version = version;
}
}
Its my fault. Couchbase populates version field.But we are requried to send version number while saving.
Another reason this could fail is that you need to have a getter for your #version field.

I am trying out Visual Paradigm for the first time. I have created a class diagram and used the Update Code button in the diagram navigator to create a java class. The issue I have is, when the class code is created, the license and author information is not being applied to the file. Is there any way to get Netbeans to insert the information when creating the file with the Visual Paradigm interface?
I used the Visual Paradigm plugin for NetBeans to create a class diagram and then used the Update Code tool to generate the Java class. But as I stated above, the licensing and author information are missing.

i m a total newbie to JPQL ,so i m working on a Spring Boot app and i have this SQL query part :
select TOP 10 RFC_NUMBER, RECIPIENT_ID from [50004].SD_REQUEST S
INNER JOIN [50004].AM_EMPLOYEE E
--ON S.RECIPIENT_ID = E.EMPLOYEE_ID
WHERE E.AVAILABLE_FIELD_5 ='j.doe'
AND SD_REQUEST.STATUS_ID NOT IN (8,6,18,7,24)
AND SD_REQUEST.RFC_NUMBER like 'I%'
to JPQL.
i tried doing a #Query like this :
#Query("select x from Incident x Left join x.recipient recip where recip.login=:login and (x.rfcnumber like :I_% or :rfcnumber = null )"
+ " and x.status NOT IN (8,6,18,7,24)")
but it only returns ALL the rfcnumber of the that employee , i want it to extract only the rfc number starting with letter I ,
i tried doing CONCAT from searching around in then web, same thing.
i m new to this so i figure it'll be something much simpler , i m thinking it's just syntax problem .
Thanks a bunch.

Hard-coded characters
I think you should use the same as in SQL:
like 'I%'
Specifically, according to the article # http://www.objectdb.com/java/jpa/query/jpql/string#LIKE_-_String_Pattern_Matching_with_Wildcards_ :
The percent character (%) - which matches zero or more of any character.
Blockquote
So try the following:
#Query("select x from Incident x Left join x.recipient recip where recip.login=:login and (x.rfcnumber like 'I%' or :rfcnumber = null )"
+ " and x.status NOT IN (8,6,18,7,24)"
)
Parameters
See the solutions # Parameter in like clause JPQL if you are using a parameter.
Examples:
LIKE :code%
Also other examples are included in the stackoverflow question.
#Query("select x from Incident x where x.recipient.login=:login and (x.rfcnumber like I% or x.rfcnumber = null )"
+ " and x.status NOT IN (8,6,18,7,24))"
try this query
When my Entity id annotation on field, it's OK on spring data jpa.
public class User {
#Id
#Column(name="id")
Long rid;
#Column(name="name")
String name;
}
but not work on method...
public class User {
Long rid;
String name;
#Id
#Column(name="id")
public Long getId() {
return this.id;
}
#Column(name="name")
public Long getName() {
return this.name;
}
}
the error message is PersistentEntity does not have an identifier property!
why?
I need to set annotation on method, because I want to set association auto.
#OneToMany(mappedBy="user")
#Cascade(CascadeType.ALL)
public Set<Phone> getPhones() {
return smtpRecords;
}
public void setPhones(Set<Phone> phones) {
phones.forEach(e -> e.setUser(this));
this.phones= phones;
}
any solution? Thanks.
I am writing an application which is based on spring boot and tries to store and retrieve data from PostGreSQL db in its jsonb column.
while saving the record it works fine but the moment i write basic method to find records in repository interface of it like this:-
public interface AgentProfileRepository extends CrudRepository<AgentProfileOuter,String> {
public AgentProfileOuter findByJdataPcpAgentId(String id);
}
then server starts giving this exception while restarting:-

Any help on this is greatly appreciated.
I think, it's because how both Mongo and PostGreSQL structure the data. From Mongo's point, AgentProfileOuter is one document saved in JSON format as key:value. Every field in your AgentProfile class is key for Mongo irrespective of the fact it's another/ child object. However, for PostGreSQL whole AgentProfile object is just one column of String blob, since you have not marked this class as #Entity and it does not have a primary id. So, when you try to search something like pcpAgentId=someid, it does not make any sense to PostGreSQL. This is my guess, verify by checking your data structure in PostGreSQL.
Also noticed that CrudRepository<AgentProfileOuter,String> should be like CrudRepository<AgentProfileOuter,long> since AgentProfilOuter class's primary key is long.
i want to insert into a table with a specified value,but it just don't work,
here is my code:
#Id
#Column(insertable=true,updatable=true)
public Long getS_id() {
return s_id;
}
#Resource(name="studentService")
private StudentService stus;
Student student = new Student();
student.setS_id(123213L);
student.setName("vincent");
stus.add(student);
If I change:
#Id
#Column(insertable=true,updatable=true)
public Long getS_id() {
return s_id;
}
to this:
#Id
#GeneratedValue(strategy=GenerationType.IDENTITY)
#Column(insertable=true,updatable=true)
public Long getS_id() {
return s_id;
}
and don't set s_id manualy it works well.
here my student class

From the limited information posted I would guess you are using SQL Server and to insert a record into an SQLServer table with an explicit value defined for an Identity column requires you to turn on identity inserts for that table.
https://msdn.microsoft.com/en-gb/library/ms188059.aspx
So if you run the above against your table you should then be able to persist using a specific value.
So not really anything to do with JPA.
