使用 :param的方式来传递参数,下面举个例子
@PersistenceContext
EntityManager em
@Override public List<Map> ajaxRelationByCompanyUUID(String companyUUID, String ajaxQuery,List<Integer> types, Integer fetchSize) { String sql = "select * from Company where companyuuid= :companyuuid" + " and CompanyType in (:types)"; Map<String, Object> params = new HashMap<String, Object>(); //公司uuid params.put("companyuuid",companyUUID); //公司类型(集合) params.put("types",types); //模糊查询 if (StringUtils.isNotBlank(ajaxQuery)) { sql += " and (CompanyNameCN like :ajaxQuery )"; params.put("ajaxQuery" ,"%" + ajaxQuery + "%"); } Query query = em.createNativeQuery(sql); for (Map.Entry<String, Object> entry : params.entrySet()) { query.setParameter(entry.getKey(), entry.getValue()); } return super.exectSqlMap(query); }
exectSqlMap:
protected List<Map> exectSqlMap(Query query) { query.unwrap(SQLQuery.class).setResultTransformer(Transformers.ALIAS_TO_ENTITY_MAP); return query.getResultList(); }
或者
public SysAppversion GetApp(String appCode, BigDecimal appVersion) { String sql = "select * from sys_appversion where AppCode= ? and AppVersion> ? order by AppVersion desc limit 1 "; List<Object> params = ListUtil.initList(Object.class); params.add(appCode); params.add(appVersion); Query query = dao.getCurSession().createSQLQuery(sql).addEntity(SysAppversion.class); for (int i = 0; i < params.size(); i++) { query.setParameter(i, params.get(i)); } if(query!=null) return (SysAppversion)query.list().get(0); return null; }
使用@Query注解
@Query(value = "select count(1) from wms_inboundorder " + " where State in (:states)" + " and IsValid = :isValid", nativeQuery = true) Integer findWmsInboundorderCount(@Param(value = "states") List<Integer> states, @Param(value = "isValid") Integer isValid);
