Spring boot Oracle JPA set QueryTimeout - database

Question

I'm using Spring Boot with Ojdbc8 18.3.0.0.0
With Hikari Datasource and JPA, all query work fine.
But now I need to set Query timeout for all database query
I was try many way:
javax.persistence.query.timeout=1000
spring.transaction.default-timeout=1
spring.jdbc.template.query-timeout=1
spring.jpa.properties.hibernate.c3p0.timeout=1
spring.jpa.properties.javax.persistence.query.timeout=1
Config Class:
#Configuration
public class JPAQueryTimeout {
#Value("${spring.jpa.properties.javax.persistence.query.timeout}")
private int queryTimeout;
#Bean
public PlatformTransactionManager transactionManager() throws Exception {
JpaTransactionManager txManager = new JpaTransactionManager();
txManager.setDefaultTimeout(queryTimeout); //Put 1 seconds timeout
return txManager;
}
}
Query:
List<Integer> llll = manager.createNativeQuery("select test_sleep(5) from dual")
.setHint("javax.persistence.query.timeout", 1).getResultList();
The database task take 5 second before return value, but in all of case, no error occor.
Could anyone tell me how to set query timeout?

Answer 1

You can try using the simplest solution, that is using the timeout value within #Transactional;
#Transactional(timeout = 1) // in seconds (so that is 1 second timeout)
public Foo runQuery(String id) {
String result = repo.findById(id);
// other logic
}
Be aware that the method annotated with #Transactional must be public for it to work properly
