Question

我是spring boot和spring data jpa的新手。我正在尝试使用本机查询基于从UI接收到的搜索属性执行搜索。

基于searchParam获取的记录应搜索searchParam是否包含在任何指定列中（如本机查询中所述）

我编写了以下代码，但最终收到标题中提到的错误。我试图在stackoverflow中查找响应。但是我相信我已经遵循了许多主题中提到的建议。

在这方面的任何帮助将不胜感激。

下面的代码段

EpicController.java

@CrossOrigin
    @RequestMapping(value="/search", method = RequestMethod.GET)
    public Page<Epic> searchEpicsByProjectIdAndSearchParam(@RequestParam String searchParam, @RequestParam String projectId, Pageable pageable) throws Exception {

        logger.info("Inside searchEpicsByAttributes() based on searchQuery API");

        Page<Epic> results = null;

        try {
            results = epicService.searchEpicsByProjectIdAndSearchParam(searchParam, projectId, pageable);
        }
        catch(Exception ex) {
            ex.printStackTrace();
            throw new Exception("Exception occurred :: " + ex.getStackTrace());
        }

        return results;
    }

EpicService.java（接口）

public interface EpicService {
   Page<Epic> searchEpicsByProjectIdAndSearchParam(String searchParam, String projectId, Pageable pageable);
}

EpicServiceImpl.java

@Override
    public Page<Epic> searchEpicsByProjectIdAndSearchParam(String searchParam, String projectId, Pageable pageable) {

        logger.info(" Inside searchEpicsByProjectIdAndSearchParam() API in EpicServiceImpl");

        return epicRepository.findBySearchParamsAndProjectId(searchParam,projectId, pageable);
    }

EpicRepository.java

@Repository
public interface EpicRepository extends JpaRepository<Issue, String> {

@Query(value = 
            "select i.* from issue i where ("
            + "upper(i.name) like upper('%?1%'))"
            +  "and upper(i.project_id) = upper('%?2%')"
            + "ORDER BY i.name DESC \n-- #pageable\n",
           countQuery = 
            "select count(i.*) from issue i where ("
            + "upper(i.name) like upper('%?1%'))"
            +  "and upper(i.project_id) = upper('%?2%')",
            nativeQuery = true)
    Page<Epic> findBySearchParamsAndProjectId(String name, String projectId, Pageable pageable);
}

例外：

Answer 1

在参数，即？1和？2周围跳过单引号“'”。工作查询如下：

"select i.* from issue i where ("
        + "upper(i.name) like upper(%?1%))"
        +  "and upper(i.project_id) = upper(%?2%)"
        + "ORDER BY i.name DESC \n-- #pageable\n",
       countQuery = 
        "select count(i.*) from issue i where ("
        + "upper(i.name) like upper(%?1%))"
        +  "and upper(i.project_id) = upper(%?2%)"

使用Spring Data本机查询
