Spring 数据 JPA nativeQuery 字符串搜索错误
Error with Spring Data JPA nativeQuery String search
请帮忙。
当我输入 searchString = "abc" 时，它就起作用了。
但是当我输入 searchString = "a" 时，它会显示以下错误：
java.sql.SQLSyntaxErrorException: Unknown column 'q' in 'field list'

这是我的存储库代码：
@Repository
public interface QuestionRepository extends JpaRepository<Question, Long> {
...
@Query(value = " SELECT q.* " +
" FROM question q " +
" WHERE q.is_private = FALSE " +
" AND (UPPER(q.title) LIKE :searchString OR UPPER(q.content) LIKE :searchString OR UPPER(q.answer) LIKE :searchString) ", nativeQuery = true)
Page<Question> test(@Param("searchString") String searchString, Pageable pageable);

}
这里是服务中的代码：
@Override
public PaginationResponse findAll(Long facultyId, String searchString, Pageable pageable) {
if (ObjectUtils.isEmpty(searchString)) searchString = "";
searchString = "%" + searchString.toUpperCase() + "%";
if (ObjectUtils.isEmpty(facultyId) || facultyId == 0) {
Page<Question> queryResult =questionRepository.test(searchString, pageable);
return convert(queryResult);
}
return convert(questionRepository.findAllByFaculty_IdEqualsAndIsPrivateFalseAndAnswerNotNull(facultyId, searchString, pageable));
}
我进行了调试，当我给 searchString= "a" 时，它没有通过 questionRepository.test(...) 方法。
糟糕，我应该使用 JPQL 而不是 nativeQuery。它现在可以与 JPQL 一起正常工作。
