kandi X-RAY | spring-data-jpa Summary

spring-data-jpa is a Java library typically used in Utilities, Object-Relational Mapping, JPA applications. spring-data-jpa has no bugs, it has no vulnerabilities, it has build file available, it has a Permissive License and it has high support. You can download it from GitHub, Maven.

Spring Data JPA, part of the larger Spring Data family, makes it easy to easily implement JPA based repositories. This module deals with enhanced support for JPA based data access layers. It makes it easier to build Spring-powered applications that use data access technologies. Implementing a data access layer of an application has been cumbersome for quite a while. Too much boilerplate code has to be written to execute simple queries as well as perform pagination, and auditing. Spring Data JPA aims to significantly improve the implementation of data access layers by reducing the effort to the amount that’s actually needed. As a developer you write your repository interfaces, including custom finder methods, and Spring will provide the implementation automatically.

            How to set fetch-size in Spring-Data-JDBC
            Asked 2022-Apr-15 at 14:09

            I use Spring-Data-JDBC (not JPA) and want to set the fetch-size.

            I know that the the classic org.springframwork.jdbc.core.JdbcTemplate has a setFetchSize(int) method, but I have Spring-Data-JDBC repository:

            Spring JPA – Multiple Databases with the same Repositories
            Asked 2022-Apr-04 at 19:37

            I have configured Spring JPA to work with multiple data sources following this example. Spring JPA – Multiple Databases

            It works as expected but since I want to use different data sources but with the same repositories there is an issue. When I try to use "Declarative Transaction Management" on my services and specify which transaction I am going to use the primary transaction or secondary one the transaction annotation is ignoring it. So in this case it is using the second one. However, both of the beans "PlatformTransactionManager" are created but when it comes to using in "@Transactional" I am not able to make the transaction work with the bean I have specified. So it seems that @Transactional is ignoring the bean name since they have the same repositories. Is there any way how can I use declarative transactions as I am trying to do it? As I have seen it can be done with Programmatic Transaction Management but it will cost me to change the whole code on my services since I have been using only declarative transactions.

            In our case, we also have two databases, both using JPA and repositories. However, they do use different repositories, but I think our approach should also work in your case. We define an EntityManagerFactory and a TransactionManager per database. I cannot confirm this works, but I believe it should.

            How does JPA EntityGraph allow chosing the entity graph at runtime?
            Asked 2022-Feb-21 at 10:48

            I have seen various post describing that JPA EntityGraph allows to choose the graph at run time. And I am not entirely clear what this refers to.

            Out of good faith and respect I would like to take this helpful article for reference: https://www.baeldung.com/jpa-entity-graph. (Most of JPA users might have gone through it already.)

            The article quotes -

            EntityGraph allows grouping the related persistence fields which we want to retrieve and lets us choose the graph type at runtime.

            and again solidifies above statement in conclusion section.

            In this article, we've explored using the JPA Entity Graph to dynamically fetch an Entity and its associations.

            The decision is made at runtime in which we choose to load or not the related association.

            As we see in the article (5.1) - EntityGraphs are defined as below using Annotations-
            5.1. Defining an Entity Graph with Annotations



            Answered 2022-Feb-18 at 15:54

            In the Baeldung article, Section 5 is only about various ways to define a graph with not much emphasis on the dynamic/non-dynamic nature of the definition itself.

            In Section 5.1 the definition of the graph is static but this section is only about demonstrating how to define a graph which then will be used in typical cases when building the graph dynamically is not really necessary. This section shows an alternative to the older way of building HQL / JPA-QL queries with JOIN FETCH sections.

            I believe the issue is that you are not adding the result in the Model which is being used to render the page show_dish_List.html, therefore nothing is being populated in the UI. Your UI is expecting the data to be in listDishSearch and there is nothing in that variable.

            I'm doing a house rental application with Spring, React and MySQL. I have a class which is like a transaction. What I'm trying to do is to get all entries for the class sweetholiday_user_house, but I only want the fields start_rent_date and end_rent_date. The table is called sweet_holiday_user_house. For that I have created a SQL query in my repository:



            Answered 2021-Dec-25 at 22:09

            You are selecting a subset (start_rent_date and end_rent_date) of the columns of the table sweetholiday_user_house. However the results are being mapped to the managed entity SweetholidayUserHouse. So the mapping fails when it looks for the id column in the resultset, which is missing.

            You can avoid this exception by either of these two approaches. There are several more. Here is a good discussion of this - Spring JPA selecting specific columns

            Option 1: Keep the existing query and change the return type of the findAllReserved() method to Object[]. Here for each Object[], Object[0] is start_rent_date and Object[1] is end_rent_date.

            It was an Intelli-J issue!

            So, cleaning the Intelli-J dependency spaghetti up solved it!

            1. File > Invalidate cache ... and restart. Helped a bit.
            2. Closing the Intelli-J project. Then removed manually the ".idea" folder and any *.iml file.
