问题 In Spring Data R2DBC I can log SQL queries by using logging.level.org.springframework.data.r2dbc=DEBUG in the application.properties . However, this doesn't log the actual values that are bound as query parameters. How can I log the actual values of query parameters in Spring Data R2DBC? 回答1: This worked for me : logging: level: io.r2dbc.postgresql.QUERY: DEBUG # for queries io.r2dbc.postgresql.PARAM: DEBUG # for parameters I found it here 回答2: If you happen to use MySQL, you can get a low

问题 I need to receive and save huge amount of data using spring data over hibernate. Our server allocated not enough RAM for persisting all entities at the same time. We will definitely get OutOfMemory error. So we need to save data by batches it's obvious. Also we need to use @Transactional to be sure that all data persisted or non was persisted in case of even single error. So, the question: does spring data during @Transactional method keep storing entities in RAM or entities which were

问题 I have the following Exception while starting the spring context: java.lang.Exception: java.lang.IllegalStateException: ContainerBase.addChild: start: org.apache.catalina.LifecycleException: org.apache.catalina.LifecycleException: org.xml.sax.SAXParseException; systemId: http://www.springframework.org/schema/data/jpa/; lineNumber: 1; columnNumber: 55; White spaces are required between publicId and systemId.

问题 I am writing an API with Spring/Mongo/Jersey to do CRUD on a POJO that has a generic map of properties like this: public class Thing { private String id; @Indexed private Map<String,String> properties; ... This is working great to return items. My resource code looks like this: BasicDBObject query = new BasicDBObject("properties.name", "vlad the impaler"); return Response.ok(myService.queryThings(query)).build(); And my abstract DAO looks like this: public List<T> find(Query query) { return

问题 I'm working on a project that keeps some access control information in the database. We're using that access control information to filter what the user can see. The filter that we're using is based on roles that the user has. We would like to use the Repository abstraction provided by Spring Data, but we would like to be able to adjust the generated queries before they are executed. Is there a way to attach a listener or an interceptor that will be called before a query is executed? That way

The field deliveryDateTime in Order entity has type LocalDateTime . I want to ignore time part and compare only date part. @Query("SELECT new OrderCountPerDate(DATE(o.deliveryDateTime), COUNT(o.id)) FROM Order o WHERE DATE(o.deliveryDateTime) IN :dates GROUP BY DATE(o.deliveryDateTime) ") List<LocalDate>

问题 I just can't seem to win today... Is there a way to read from a OneToMany relationship in a Spock SpringBootTest integration test, without annotating the test as @Transactional or adding the unrealistic spring.jpa.properties.hibernate.enable_lazy_load_no_trans=true ? OR, is there a way to launch a Spring-Batch Job from within a @Transactional test case? Let me elaborate... I'm trying to get a simple Spring Boot Integration test working for my Spring Batch reporting process, which reads from

问题 in our Spring application we have a table that contains a lot of "Payment" record. Now we need a query that pages the results sorted from the one with the largest total to the smallest, we are facing an error because sometimes the same record is contained in two successive pages. We are creating a PageRequest passed to the repository. Here our implementation: Repository: public interface StagingPaymentEntityRepository extends JpaRepository<StagingPaymentEntity, Long> { Page
