I am writing an application which contains an entity with property named addedDate of type Date.
I have written an interface which extends MongoRepository and defined a method named
findByAddedDateBetween(Date startDate,Date endDate);
But when I query with 2 dates the output only contain list entities between the dates,Not including the entities whose addedDates is the queried dates. I want to include the boundary values also.
According to Spring JPA documentation for MongoDB, the between keyword is not inclusive in Mongo DB if you use 2 parameters.
As an alternative, you can use the spring Range class. You must use this method in order to include boundaries.
findByAddedDateBetween(Range<Date> range)
Where Range is declared like this :
Range<Date> range = Range.of(Range.Bound.inclusive(dateStart), Range.Bound.inclusive(dateEnd));

Let's say I have an Entity class with one parameter in Spring, the parameter
private int value;
Now I have an Postgres database connected with Spring Jpa, and I have multiple entrys with the value in the database. How can I search for a certain range of the value from the database. For example I want to have the values from the range 20 till 100. I know there is are methods in Jpa but none of these really didnt help me or I used them wrong:
Need help with Spring JPA. Say I want to find who checkout the car when gotten a traffic ticket. So that licenseNum and
citationDate is greater than checkoutDate and citationDate is less than returnDate; or
citationDate is greater than checkoutDate and returnDate is null.
Currently,
List<SomeEntity> findByLicenseNumAndCheckOutDatetimeBeforeAndReturnDatetimeAfterOrReturnDatetimeIsNullOrderByIdDesc()
produces #1 correctly but produces all licenseNum with returnDate null.
How do I write spring JPA statement with 'or' statement correctly?
You can actually think of using a Query annotation where you can specify a custom query. Yon can choose a more meaningful method name and easy to maintain/change.
I want to write query (properties or yaml) in external file to load database. -
This is long query and does not look good to eye when placed inside #Query("long query") in XXXRepository class.
Is there way to write this query in an external file (properties, yaml, xml or json) and call that file in #Query() in spring data jpa?
You can use named queries, where the queries have to be defined in a file called META-INF/jpa-named-queries.properties. See the spring example:
User.findBySpringDataNamedQuery=select u from User u where u.lastname=?1
Reference the query by name in the annotation in your repository, here the corresponding repository example from spring:
#Query(name = "User.findBySpringDataNamedQuery", countProjection = "u.firstname")
Page<User> findByNamedQueryAndCountProjection(String firstname, Pageable page);
As suggested by Ralf Stuckert, use META-INF/jpa-named-queries.properties to store named queries
You can use \ to split the long query into multiple lines.
Example:
Customer.findNameNative=\
SELECT C.NAME \
FROM CUST_TABLE C \
WHERE CONDITIONS
I think you're finding a place to put your big query string as readable? Like Mybatis xml. As my knowledge There is no method to do that in data jpa.
But you can put that big query inside of a Stored Procedure and call it easily like below.
Call your_stored_procedure_name(param1,param2):
I am working with a legacy system which requires doing a query for a partial match on a number field. So I want to do something like
where ID like concat(:num, '%') where num parameter is of the type Long. Is there a way to do that using Spring Data JPA derived queries. If the id was a string then I can simply do
findByIdContaining(String id)
I would appreciate any help.
No, this is not possible with derived queries (those where the query is derived from the method name). But it's easy with an annotated #Query annotation.
I am using spring data jpa and JQGrid. I need response based on multiple sort parameters.
I tried using sort parameter=column a,column b and sort order=asc but I am getting an exception
:No property column a,column b found in pojo.
It works if I would pass either of one columns as sort parameter.
Code:
Pageable pageable = JPAUtility.constructPageSpecification(pageNumber, rowsPerPage, sortColName, sortOrder);
How can I pass multiple column names in sortColName parameter?
In Spring Data you just need to add Sort parameter into findBy* method. Sort object has got a couple constructors, e.g.
Sort(Direction direction, String... properties)
which is probably exactly what you need. If you need to specify different directions for various properties then you can use
Sort(Order... orders)
where Order has property and direction: Order(Direction direction, String property)
