A weird behaviour when I update my entity using this query:
#Query("UPDATE profile SET firstName=:newProfileFirstName AND lastName=:newProfileLastName WHERE userId = :userId")
fun updateProfileFullName(
newProfileFirstName: String,
newProfileLastName: String,
userId: Long
) : Completale
The issue is after update I always get : firstname set to 0.
Solved by replacing AND by ,
#Query("UPDATE profile SET firstName=:newProfileFirstName AND lastName=:newProfileLastName WHERE userId = :userId")
become :
#Query("UPDATE profile SET firstName=:newProfileFirstName, lastName=:newProfileLastName WHERE userId = :userId")

I should save the record in the database and get the record id in the response. After a long search and research I came up with the following option.
data class User(
val id: UUID? = null,
val username: String,
...
)
UserRepo:
#Options(useGeneratedKeys = true, keyProperty = "id", keyColumn = "id")
#Insert("""
INSERT INTO "user" (
username,
...
) VALUES (
#{username},
...
)
""")
fun save(user: User): User
in response I get the following.
org.apache.ibatis.binding.BindingException: Mapper method '...UserRepository.save' has an unsupported return type: class ...entity.User
in the following case, I don't get an error, but I don't get an id either, how can I do it correctly? Used Select instead of Insert
#Options(useGeneratedKeys = true, keyProperty = "id", keyColumn = "id")
#Select("""
INSERT INTO "user" (
username
) VALUES (
#{username}
)
""")
fun save(user: User): User
if we solve my first question, then I would like to know if it is possible to get the answer not in the User class, but in another one, for example, UserResponse? That is, send a request to the User class, and receive a response in the UserResponse
UPDATE
I was able to get the id after changing the id type to String.
Like this:
data class User(
val id: String? = null,
val username: String,
...
)
Apparently some settings are needed for UUID?
Has anyone faced such a problem?
Hi I'm working on a Spring Boot Project using PSQL. I have a model that is implemented pgcrypto like this,
#ColumnTransformer(
read = "pgp_sym_decrypt( msisdn::bytea, 'mypassword' )",
write = "pgp_sym_encrypt( ?, 'mypassword' )"
)
#Column(name="msisdn")
private String msisdn;
In my JPArepository every function like find(), findAll(), findBySomthing(..) work perfectly. The result decoded my msisdn record correctly.
But it's not working on a navtiveQuery. For example in my JPArepository,
#Query(value = "SELECT id, pgp_sym_decrypt( msisdn::bytea, 'mypassword' ) as msisdn FROM tbl_payments ORDER BY id ASC;", nativeQuery = true)
List<MyClass> test();
It always throws error
org.postgresql.util.PSQLException: ERROR: syntax error at or near ":"
But the query is correct because I already copied it to do a query directly on Database.
Do I need anything extra to work with JPA nativeQuery ?
Please help. Thanks a lot.
Your query:
#Query(value = "SELECT id, pgp_sym_decrypt( msisdn::bytea, 'mypassword' ) as msisdn FROM tbl_payments ORDER BY id ASC;", nativeQuery = true)
List<MyClass> test();
just add \:\: at :: in bytea
Improved query:
#Query(value = "SELECT id, pgp_sym_decrypt( msisdn\\:\\:bytea, 'mypassword' ) as msisdn FROM tbl_payments ORDER BY id ASC;", nativeQuery = true)
List<MyClass> test();
I need to retrieve a list of Category from the DB on the basis of value of column called owner. Here is my Category -
#Entity
#Table(name = "categories")
class Category(#Column(name = "category_id", nullable = false)
#Id #GeneratedValue(strategyGenerationType.AUTO)
var id: Long = 0,
#Column(name = "category_owner", nullable = false)
#field:NotNull(message = "Please assign an owner")
var owner: Long?,
#Column(name = "category_name", nullable = false)
#field:NotEmpty(message = "Please assign a name")
var name: String?)
Here is my interface which defines the function findByOwner -
interface CategoryRepository: JpaRepository<Category, Long> {
fun findByOwner(categoryOwner: Long): List<Category>
}
However, when I call the method, I get no response. I have made sure that the DB has correct data and I'm providing the correct owner Id. Have even invalidated the cache etc. What could be going wrong?
EDIT:
After spring.jpa.show-sql=true -
findAll()
Hibernate: select category0_.category_id as category1_0_, category0_.category_name as category2_0_, category0_.category_owner as category3_0_ from categories category0_
findByOwner()
Hibernate: select category0_.category_id as category1_0_, category0_.category_name as category2_0_, category0_.category_owner as category3_0_ from categories category0_ where category0_.category_owner=?
EDIT 2:
Turns out that my implementation was fine all along. The bug was in my service.
Create your named method according with the name of the column.
fun findByCategoryOwner(categoryOwner: Long): List<Category>
Or use #Query
#Query("SELECT * FROM categories WHERE category_owner = ?1", nativeQuery = true)
fun findByOwner(cateogryOwner: Long): List<Category
Can you put a breakpoint in org.springframework.data.jpa.repository.query.JpaQueryExecution class and when you execute findByOwner, it will come here.
When it reaches this breakpoint, select the query.createQuery(accessor).getResultList() and evaluate to see what value is returned by hibernate for spring-data-jpa to use
This post should help you. It appears to be happeing because of the parameter name mismatch.
Use camelCase to name your variables in Entity class then jpa will auto recognise the column name
findByCategoryOwner(String categoryOwner)
If you still wish to have underscore in your column names then try this
findByCategory_Owner(String categoryOwner)
I haven't tried the second option though
At least in java you need to provide the id in the method name:
**fun findByOwner_Id(categoryOwner: Long): List<Category>**
So change it from findByOwner -> findByOwnerId.
I need to check is user with a specified id and token exists. Tokens are stored in #ElementCollection set. I tried to write a derived query method in my repository like this:
boolean existsByIdAndTokensContains(long id, String token);
But that isn't working (returns false for right input values).
When I tried to specify query explicitly it start working right:
#Query("select (count(u) > 0) from users as u where u.id = :id and :token member of u.tokens")
The most strange that Hibernate logs are looking similar for both queries:
For the derived query:
/* select
generatedAlias0.id
from
users as generatedAlias0
where
(
generatedAlias0.id=:param0
)
and (
:param1 member of generatedAlias0.tokens
) */ select
userentity0_.id as col_0_0_
from
users userentity0_
where
userentity0_.id=?
and (
? in (
select
tokens1_.token
from
users_tokens tokens1_
where
userentity0_.id=tokens1_.user_id
)
) limit ?
For the explicit query:
/* select
(count(u) > 0)
from
users as u
where
u.id = :id
and :token member of u.tokens */ select
count(userentity0_.id)>0 as col_0_0_
from
users userentity0_
where
userentity0_.id=?
and (
? in (
select
tokens1_.token
from
users_tokens tokens1_
where
userentity0_.id=tokens1_.user_id
)
)
And when I tried to query generated query, result contained the right user.
What am I do wrong?
I would think you need to implement an Attribute Converter to convert the id into a Boolean. This way it will know how to map a not null Id to a true value.
Ok, I found the solution.
For my Set of tokens:
#ElementCollection
#Column(name = "token", nullable = false)
#CollectionTable(name = "users_tokens", joinColumns = #JoinColumn(name = "user_id"),
uniqueConstraints = #UniqueConstraint(columnNames = {"user_id", "token"}))
private final Set<String> tokens;
Works the similar query but without Contains:
boolean existsByIdAndTokens(long id, String token);
I don't know is it a bug, but this works for me.
I have a case statement in my Native query where I am attempting to override a field in my entity.
SELECT i.id, i.ONE_TO_ONE_ID, i.ANOTHER, CASE(WHEN condition THEN 'YES' WHEN another_condition THEN 'NO' ELSE 'MAYBE' END) as word ....
I am using this with JpaRepository as a native query, with pagination.
When I run the native query against my db directly, the result set looks as though I expect.
| id_value | MAPPED_ENTITY_ID_value | another value | word_value (YES) |
When I run the native query from my JpaRepository, everything works there, except word is always null. I cant' seem to figure out how to map the additional String word result to a field in my Entity.
Is there a way to get this to map? Or will I have to create an entire #SqlResultSetMapping() for all of my fields coupled with a native query? (hoping not)
UPDATE: 1
I was generalizing above. Here is my Query.
#Query(
name = "listPagedMapping",
value = "SELECT DISTINCT i.ID, i.INSTANCE_ID, i.REGION, i.CNAME_STACK_ID, i.INSTANCE_STATE, i.IP_ADDRESS, i.EC2_ROLE_NAME, i.INSTANCE_OWNER, i.IS_MASTER, i.EC2_MASTER_ID, i.CNAME, i.EC2_START_TIMESTAMP, i.PRIVATE_DNS, i.INSTANCE_NAME, i.AUTO_TERMINATE, i.AUTO_TERMINATE_DATE, i.TERMINATION_ZONE, i.ADMIN_GROUP_AD_LDAP_ID, i.USER_GROUP_AD_LDAP_ID, (CASE WHEN i.INSTANCE_OWNER=:username THEN 'OWNER' WHEN i.ADMIN_GROUP_AD_LDAP_ID IN (g.AD_LDAP_ID) THEN 'ADMIN' WHEN i.USER_GROUP_AD_LDAP_ID IN (g.AD_LDAP_ID) THEN 'USER' END) as PERMISSION FROM USER u, USER_ACCESS_GROUPS g, EC2_PROVISIONING i WHERE i.INSTANCE_OWNER=:username and i.INSTANCE_STATE in (:instanceStates) or u.username=:username and i.INSTANCE_STATE in (:instanceStates) and g.USER_ID=u.USER_ID and (i.ADMIN_GROUP_AD_LDAP_ID IN (g.AD_LDAP_ID) or i.USER_GROUP_AD_LDAP_ID IN (g.AD_LDAP_ID))",
countQuery = "SELECT count(*) FROM (SELECT DISTINCT i.* FROM USER u, USER_ACCESS_GROUPS g, EC2_PROVISIONING i WHERE i.INSTANCE_OWNER=:username and i.INSTANCE_STATE in (:instanceStates) or u.username=:username and i.INSTANCE_STATE in (:instanceStates) and g.USER_ID=u.USER_ID and (i.ADMIN_GROUP_AD_LDAP_ID IN (g.AD_LDAP_ID) or i.USER_GROUP_AD_LDAP_ID IN (g.AD_LDAP_ID))) as ug",
nativeQuery = true)
Page<Ec2Instance> findAllByPermissionUserAdminOrOwnerAndInstanceStateIn(
#Param("username")final String username,
#Param("instanceStates") final Set<String> instanceStates,
final Pageable pageable);
}
Obviously a bit more complex.
I can get it to map to the entity field with using a named query, but then I loose all the default mappings:
#JsonInclude(JsonInclude.Include.NON_NULL)
#SuppressWarnings("unused")
#Data
#AllArgsConstructor
#NoArgsConstructor
#EqualsAndHashCode(exclude={"masterNode", "workers", "associatedBuckets"})
#Entity
#Table(name = "EC2_PROVISIONING")
#SqlResultSetMapping(
name="listPagedMapping",
columns = {
#ColumnResult(name = "permission", type = String.class)
}
)
#NamedNativeQuery(
name = "listAccessibleInstances",
query = ACCESSIBLE_QUERY,
resultSetMapping = "listPagedMapping"
)
public class Ec2Instance {
....
private String permission;
#column(name = "INSTANCE_ID")
private String instanceId;
#ManyToOne
#JoinColumn(name = "EC2_MASTER_ID")
private Ec2Instance masterNode;
#Setter(AccessLevel.NONE)
#ManyToMany(fetch = FetchType.EAGER)
#JoinTable(name = "WORKER_EC2_NODES", joinColumns = { #JoinColumn(name = "EC2_MASTER_ID") }, inverseJoinColumns = {
#JoinColumn(name = "ID") })
private Set<Ec2Instance> workers = new HashSet<>();
... More fields ..
}
I guess, I am hoping there is a way to provide a single mapping on-top of the default mapping that is done by ORM. The above code results in only a pageable of Content PERMISSION, rather than the whole entity + permission.
UPDATE: 2
Ok, so I am getting closer... Seems by removing the #ColumnResult I do get the default mapping, plus the PERMISSION field mapped over! Looks like this:
#SqlResultSetMapping(
name="listPagedMapping"
)
The last issue is it does not accept my CountQuery, and causes my tests to fail whenever a Pagination Query results with multiple pages. Looks like Spring try's to come up with its own CountQuery, which is not correct.
UPDATE: 3
To finish this off, looks like I can provide the Count Query as described here: Spring Data - Why it's not possible to have paging with native query
I will give this a go and update back.
I never got this to work quite how I wanted. I am sure I could by mapping my entire entity, but, that would have been painstaking. I ended up solving this by using NamedNativeQueries, with mapping for the additional Column as a result of my Case statement. My entity class is now annotated like:
#JsonInclude(JsonInclude.Include.NON_NULL)
#SuppressWarnings("unused")
#Data
#AllArgsConstructor
#NoArgsConstructor
#EqualsAndHashCode(callSuper = false)
#Entity
#Table(name = "EC2_PROVISIONING")
#SqlResultSetMappings({
#SqlResultSetMapping(
name = "listPagedMapping",
entities = {
#EntityResult(
entityClass = Ec2Instance.class
)
},
columns = {#ColumnResult(name = "permission", type = String.class)}
),
#SqlResultSetMapping(name = "listPagedMapping.count", columns = #ColumnResult(name = "cnt"))
})
#NamedNativeQueries({
#NamedNativeQuery(
name = "Ec2Instance.listAccessibleInstances",
query = ACCESSIBLE_QUERY,
resultClass = Ec2Instance.class,
resultSetMapping = "listPagedMapping"
),
#NamedNativeQuery(
name = "Ec2Instance.listAccessibleInstances.count",
resultSetMapping = "listPagedMapping.count",
query = ACCESSIBLE_QUERY_COUNT
)
})
We also dont need the permission field in this entity anymore. I removed that.
Then in my Repository:
Page<Object[]> listAccessibleInstances(
#Param("username")final String username,
#Param("instanceStates") final Set<String> instanceStates,
final Pageable pageable);
Thats it! Now the result of my case statement is returned with each entity.
Object[0] = original, default mapped entity.
Object[1] = permission
