неожиданный узел AST: как весной JPA данных

Я хочу реализовать некоторую функциональность, которая, когда я ввожу текст внеожиданный узел AST: как весной JPA данных

<input path="tags" id="input-search"/>

должен появиться список предлагаемых тегов так же, как

я нашел некоторые вещи spring-mvc-jquery-autocomplete-example, который

public interface TagRepository extends JpaRepository<Tag, Integer> {  
    @Query("select t from Tag t where name = :name LIKE '%'") 
    List<Tag> findTagByName(@Param("name") String name);  
}

и тому Код контроллера

@RequestMapping(value = "/getTags", method = RequestMethod.GET) 
    public @ResponseBody 
    List<Tag> getTags(@RequestParam String tagName) { 

     return tagService.findTagByName(tagName); 

    }

наконец взгляд

<script src="<c:url value="/resources/core/jquery.1.10.2.min.js" />"></script> 
<script src="<c:url value="/resources/core/jquery.autocomplete.min.js" />"></script> 
<input path="tags" id="input-search"/> 
<script> 
    $(document).ready(function() { 

    $('#input-search').autocomplete({ 
     serviceUrl: '${pageContext.request.contextPath}/getTags', 
     paramName: "tagName", 
     delimiter: ",", 
     transformResult: function(response) { 

     return {   
      //must convert json to javascript object before process 
      suggestions: $.map($.parseJSON(response), function(item) { 

       return { value: item.tagName, data: item.id }; 
      })}; 
     }   
    });     
    }); 
    </script>

Я получаю ошибку при

@Query("select t from Tag t where name = :name LIKE '%'")

и StackTrace является

Ваш синтаксис запроса прав? – Selva

Не знаю, как я новичок. –

Вот запрос, вы должны использовать, если вы хотите, чтобы функция автозаполнения для работы:

@Query("select t from Tag t where name LIKE CONCAT(:name, '%')")

Или использовать это, если вы хотите, чтобы соответствовать javascript при вводе script:

@Query("select t from Tag t where name LIKE CONCAT('%', :name, '%')")

Я попробовал '@Query (" select t from Tag t где name LIKE CONCAT ('%',: name, '%') ")' и получил __unexpected токен: имя около строки 1, столбец 57 [select t from Tag t где имя LIKE CONCAT ('%',: name, '%')] __ –

У вас есть таблица с именем 'Tag' и столбец с именем' name'? – mbinette

Да, конечно! –

это просто ошибка синтаксиса запроса SQL,

Вы пытаетесь сделать запрос равно и как в то же время, вы можете сделать что-то вроде этого:

@Query ("выберите т из тегов т где имя, как: имя ")

источник

Ваш HQL не определена.

select t from Tag t where name = :name LIKE '%'

должен быть чем-л, как

select t from Tag t where name LIKE '%:name'

также, если вы хотите искать, начиная с: имя

select t from Tag t where name LIKE ':name%'

или содержащие текст в любом месте строки, то используйте

select t from Tag t where name LIKE '%:name%'

Что относительно ключевого слова «где» в вашем запросе? Попробуйте это. @Query ("выберите c из категории c, где имя LIKE '%: name%'") –

Извините, что я ошибся, комментируя фактическое значение __ @ Query ("select t from Tag t где name LIKE '%: name%'") __ и получил __unexpected токен: имя рядом с строкой 1, столбец 57 [выберите t из тега t, где имя LIKE CONCAT ('%',: name, '%')] __ –
