How to Combine And and Or Operators in Spring Data JPA Method Names?

Using Multiple Logical Operators in JPA Method Names

In Spring Data JPA, method names can be used to generate queries, offering a concise and intuitive way to access data. However, when needing to use both And and Or operators in a method name, challenges can arise.

Consider the following example:

<code class="java">findByPlan_PlanTypeInAndSetupStepIsNullOrStepupStepIs(...)</code>

When translated into a query, this method would execute as:

[(exp1 and exp2) or (exp3)]

However, the desired result is:

[(exp1) and (exp2 or exp3)]

Using the simple method name convention, achieving this goal through Spring Data JPA seems daunting.

One approach to address this issue is to utilize an equivalency between logical operators:

A /\ (B \/ C) <=> (A /\ B) \/ (A /\ C)

Translated to method names, this would result in:

<code class="java">findByPlan_PlanTypeInAndSetupStepIsNullOrPlan_PlanTypeInAndStepupStepIs(...)</code>

By utilizing this equivalency, the query can be generated correctly to match the desired condition.
