如何缩短 Spring Data JPA 存储库中查询方法的名称? [英] How to shorten names of query methods in Spring Data JPA Repositories?

问题描述

考虑一个 Spring Data Jpa 存储库:

Consider a Spring Data Jpa Repository:

public interface UserRepository extends JpaRepository<User, Long> {

    User findOneByDeletedIsFalseAndActivationKey(String activationKey);

    List<User> findAllByDeletedIsFalseAndActivatedIsFalseAndCreatedDateBefore(DateTime dateTime);

    User findOneByDeletedIsFalseAndLogin(String login);

    User findOneByDeletedIsFalseAndEmail(String email);

}

请注意，每个方法中都有DeletedIsFalse".有没有一种简单的方法可以使方法名称更短?比如:

Notice each method has "DeletedIsFalse" in it. Is there a simple way to make method names shorter? Like i.e.:

@FullMethodName("findOneByDeletedIsFalseAndEmail")
User findOneByEmail(String email);

推荐答案

使用 default Java 8 特性进行包装，就像这样:

Use default Java 8 feature for wrapping, just like so:

// use findOneByEmail instead
User findOneByDeletedIsFalseAndEmail(String email);

default User findOneByEmail(String email) {
    return findOneByDeletedIsFalseAndEmail(email);
}

参见 an示例.
