In Spring Data JPA, you can specify projections at runtime using generic repository methods. To make query async, place the cursor on the query you want to change and choose the result return type from the drop-down list: Learn more about asynchronous query results at the corresponding Spring Data JPA documentation page. To make a query asynchronous, it's not enough to add the annotation, it's also necessary to change the return type to one of the following: Spring Data JPA provides the ability to run repository queries asynchronously. JPA Buddy supports them, so you can build graphs using a handy GUI wizard: Entity graphs give us another layer of control over data that needs to be fetched. The EntityGraph has been one of the most awaited features introduced in JPA 2.1. To configure the method or query, place a cursor on it and use JPA Inspector: If you have naming standards established for the development team, you can configure JPA Buddy to use only approved keywords for method names generation: On the other hand, in big teams, different naming for the same actions may be confusing for code reviewers and maintainers. On the one hand, it gives us some flexibility in methods naming. You can use NameContaining, NameIsContaining, or NameContains - the result is the same. Spring Data provides several keyword expressions for derived query method names. Just write the desired signature and move to the query or method creation wizard via special actions: JPA Buddy can help those developers who prefer to call a method that doesn't exist yet first and only then implement it. In the opened window, choose the required type of query/method. Place the cursor on the desired attribute, press Alt+Enter (or Opt+Enter on Mac), and click on the Create Spring Data repository method. JPA Buddy also provides intention on the entity attributes leading directly to the query/method creation window. This allows you to customize the naming convention for the generated query method, providing flexibility and consistency in your code. Instead of using the Method name field, you can utilize the Method prefix drop-down menu to define the desired subject keyword and add an alias. The same approach applies to derived query methods. Where upper(o.firstName) like upper(concat(:firstName, '%'))Īnd upper(o.lastName) like upper(concat('%', :lastName, '%')) whether to use Pageable parameter or not įinally, you can specify fields you want to order the query result by.įor the above configuration, the following query will be generated: distinct o from Owner o.whether the parameters will be named or not. The middle of the window contains the table for the query conditions.Īt the bottom of the window, you can specify: Still, if you leave it empty, the name will be generated automatically following Naming Conventions for Query. Moreover, JPA Buddy allows you to generate new Projection interfaces or DTO classes by clicking on the + button. Let's look at an example of creating a Find Collection Query.Īt the top of the window, you can define the wrap type for collections' and queries' return type. As opposed to the derived query method's name can only be generated automatically according to Naming Conventions for Queries or by specifying its Subject Keyword.
