at it.eng.eled.data.services.meters.MeterService$$FastClassBySpringCGLIB$$62d07def.invoke(<generated>)
Method called is:
#Query("SELECT m FROM Meters m JOIN FETCH m.metersInternationalizations mi LEFT JOIN FETCH m.uoM uom LEFT JOIN FETCH uom.uoMInternationalizations uomi WHERE m.plants.id = :plantId AND mi.id.languageId = :languageId AND uomi.id.languageId = :languageId ORDER BY m.id")
public List<Meters> findUnregisteredMeters(#Param("plantId") Integer plantId, #Param("languageId") Integer languageId, Pageable pageable);
The problem would seem to be related to queries that contain Pageable and order by. Maybe something is changed in new spring data jpa.
Have you any idea?
Thanks

it would seem that in JPA 2.0, when a Pageable is used, it is mandatory to set the sortColumn and avoid order by directly in the query string.
So the query works either with Pageable at null (with order by in query string) or, if you use the Pageable, setting the sortColumn (without order by).
Worked rest call:
{"languageId":1,"plantId":1,"pagination":{"pageNumber":"1","pageSize":"8","offset":"0","sortColumn":"id","sortDirection":"Ascending"}}
{"languageId":1,"plantId":1}

#PreUpdate is getting called during fetch operation

I have upgraded the spring-boot application from 1.5.10 to 2.2.2.
I have one method which gets called on the login page before a user is authenticated. So that method is marked as permitAll() in the security configuration. This method calls userRepository to fetch data from db.
JPA code looks as below:
#Query("SELECT t2 FROM table t1 INNER JOIN t1.table2 t2 WHERE t1.id = :param1 and t2.id = :param2")
SomeEntity getsomedata(#Param("param1") long param1, #Param("param2") long param2);
Each entity is audited. The method is only fetching data and not updating any entity.
Still, #PreUpdate method is being called. In #PreUpdate method , we are taking the authenticated user to log some info to audit tables. So call to fetch db data is getting failed, as the user is not authenticated.
Why #PreUpdate is getting called as we are not updating any data?
This was working in spring boot 1.5.10 version
Does fetching data using #Query calls flush() method?
As I can see logs after get call flush method is being called.

Spring Boot: Apparent connection leak detected on long running stored procedure

There is a method which calls a stored procedure.The procedure can run for long hours depending on input. After the completion of procedure, there is an update statement. HikariCP-Connection leak is detected at the method which calls procedure and procedure fails sometimes. Please mention on any particular properties to be changed for HikariCP(currently using default properties) or any changes to be made in the code to solve this issue.
public void procedure (String[] names){
try(Connection connection = getJdbcTemplate().getDataSource().get connection()){
Oracle connection oracleConnection = connection.unwrap(OracleConnection.class);
AbstractSqlTypeValue names = new OracleArrayType(oracle connection,names);
.... //execute procedure
....// update status
}catch block
}

The issue is because of the property spring.datasource.hikari.leakDetectionThreshold
Increase the leakDetectionThreshold to 20000 or whichever is suitable for your application to avoid the error.
Property explanation, LeakDetectionThreshold informs about potential leaks when you don't close your connection in defined limit of time. Here probably you have query (or something inside try clause) that takes longer than x seconds.

Spring boot, db resilience

My goal is to make my app resilent for db connection issues (used db postgres)
So I have the following config:
spring.datasource.url=jdbc:postgresql://${DB_HOST}:${DB_PORT}/${DB_NAME}
spring.datasource.username=${DB_USER}
spring.datasource.password=${DB_PASS}
spring.datasource.driver-class-name=org.postgresql.Driver
spring.datasource.hikari.minimumIdle=1
spring.datasource.hikari.maximumPoolSize=${MAX_DB_CONNECTIONS}
spring.datasource.hikari.idleTimeout=10000
spring.datasource.hikari.poolName=SpringBootJPAHikariCP
spring.datasource.hikari.maxLifetime=2000000
spring.datasource.hikari.connectionTimeout=30000
This works as the application doesn't crash but the goal is that if the db connection is gone for less then 30 seconds, the rest calls work (with this config I get a 409 error when the db connection is not available), how to archive this?
Update:
The exception that I currently get:
SpringBootJPAHikariCP - Connection org.postgresql.jdbc.PgConnection#45614709 marked as broken because of SQLSTATE(08006), ErrorCode(0)

Can't configure EntityManager with Transactional using Spring Boot

Currently I am writing Spring boot application to move data from Database in source A to another Database in source B. To do so, I am trying to configure Spring with two datasource and tried to retrive data from source A concurrently and insert to source B. I could retrieve data from source A but the problem is that I could not insert those data to source B. It seems like I didn't configure transactional correctly with EntityManager. Please check my below code and help me figure out this.
Here is my datasource configuration class:
#Configuration
#EnableJpaRepositories(
basePackages = ["com.gdce.xgen.repo.psql"],
entityManagerFactoryRef = "psqlEntityManager",
transactionManagerRef = "psqlTransactional")
#EnableTransactionManagement
#ComponentScan("com.gdce.xgen.repo.psql")
class PsqlDataSource {
#Bean("psqlEntityManager")
fun entityManagerFactory(#Qualifier("psqlDataSource1") dataSource: DataSource): LocalContainerEntityManagerFactoryBean {
val em = LocalContainerEntityManagerFactoryBean()
val vendorAdapter: JpaVendorAdapter = HibernateJpaVendorAdapter()
em.dataSource = dataSource
em.jpaVendorAdapter = vendorAdapter
em.setPackagesToScan("com.gdce.xgen.model.psql")
em.setJpaProperties(hibernateProperties())
return em
}
#Bean("psqlDataSource1")
#ConfigurationProperties("psql.datasource.main.configuration")
fun dataSource(#Qualifier("psqlDataSourceProperties") dataSourceProperties: DataSourceProperties): DataSource {
return dataSourceProperties.initializeDataSourceBuilder().type(HikariDataSource::class.java).build()
}
#Bean("psqlDataSourceProperties")
#ConfigurationProperties("psql.datasource.main")
fun dataSourceProperties(): DataSourceProperties {
return DataSourceProperties()
}
#Bean("psqlTransactional")
fun transactionManager(#Qualifier("psqlEntityManager") entityManager: EntityManager, #Qualifier("psqlDataSource1") dataSource: DataSource): PlatformTransactionManager {
val transactionManager = JpaTransactionManager(entityManager.entityManagerFactory)
transactionManager.dataSource = dataSource

Here is the class I use to insert data into destination data source
#Service
class InsertRepo {
#Qualifier("psqlEntityManager")
// #Autowired // also tried this but not working and saw many people use #PersistenceContext and tried it too
#PersistenceContext
private lateinit var entityManager: EntityManager

If i modify my InsertRepo to:
#Service
class InsertRepo {
#Qualifier("psqlEntityManager")
#PersistenceContext
private lateinit var entityManager: EntityManager
#javax.transaction.Transactional
fun migrate(records: ArrayList<Any>) {
records.parallelStream().forEach { record ->

DataRetrievalFailureException when saving aggregate root using Azure SQL Server

Problem Description -
Saving aggregate roots without embedded entities works fine
The issue arises when saving an aggregate root which aggregates another entity (one-to-one containment relationship)
Spring Data JDBC seems to behave correctly as I see the correct prepared statements (insert of root entity, get generated keys, and then insert of the aggregated entity)
It seems to me the issue arises within the GenerateKeyHold class which is receiving a "keyList" with one entry "[{GENERATED_KEYS=null}]"
The code tests against an empty list but not against a null GENERATED_KEYS
The database driver correctly inserts the row but then the code tries to retrieve a generated id but it is null and hence the cast exception
I am including sample code (entity, script-creation) and the stack trace
Note that I didn't observe this issue when using the in-memory H2 database
I am using spring-boot-starter-data-jdbc:jar:2.1.3.RELEASE which is pulling spring-data-jdbc:jar:1.0.5.RELEASE
I would really appreciate if you could help me figure out the cause of such an issue; I did lot of research but nobody is reporting such a problem (except for an Oracle DB because of ROWID to Number casting)
Entities
// EntityA owns an instance of EntityB
#Data
static class EntityA {
#Id Long id;
String field1;
EntityB entityB;
}
#Data
static class EntityB {
String field2;
}

This is a bug/missing feature in Spring Data JDBC.
Support for MS SqlServer isn't really there yet.
Could you create an issue for this?
And since you seem already digging a little into the code, maybe you might even want to submit a PR?
