Question

我正在使用带有注释的Spring Data 我想通过存储库调用带有参数（LocalDate）的本机命名查询当我调用此查询时，我收到此错误：

o.h.engine.jdbc.spi.SqlExceptionHelper   : SQL Error: 1271, SQLState: HY000
o.h.engine.jdbc.spi.SqlExceptionHelper   : Illegal mix of collations for operation '<'

这是我的代码，我在param中输入的日期是正确的（＆＃34; 2017-02-01＆＃34;）。：

具有命名查询的实体：

@Entity
@Table(name = "stock")
@Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)
@NamedNativeQuery(name = "Stock.getPlanningFromStock",
    query = "Select s.nom from stock where s.entry_date = :date1", resultSetMapping = "planningFromStockMapping" )

Spring MVC资源

@RequestMapping(value = "/stock-planning/{entryDate}",
        method = RequestMethod.GET,
        produces = MediaType.APPLICATION_JSON_VALUE)
@Timed
public List<PlanningDTO> getPlanning(@PathVariable @DateTimeFormat(pattern = "yyyy-MM-dd") LocalDate entryDate ) {


    List<PlanningDTO> plannings = stockRepository.getPlanningFromStock(entryDate);
    return null;
}

存储库：

List<PlanningDTO> getPlanningFromStock(@Param("date1") LocalDate date1);

Spring Data：使用LocalDate参数
