java无法将sql（jpa查询）返回的列转换为自定义类

Question

有人问过这个问题，但我无法解决我的问题

上一个问题：How to return a custom object from a Spring Data JPA GROUP BY query

在我的项目中，我有一个自定义类，定义如下：

public class VerticalBarChartDomain {

    private String name;
    private Long value;
    // constructors
    public VerticalBarChartDomain() {
        // TODO Auto-generated constructor stub
    }
    public VerticalBarChartDomain(String name, Long value) {
        super();
        this.name = name;
        this.value = value;
    }
    //getters and setters
    public String getName() {
        return name;
    }
    public Long getValue() {
        return value;
    }
    public void setName(String name) {
        this.name = name;
    }
    public void setValue(Long value) {
        this.value = value;
    }

}

在JPA存储库中，我有一个查询，如下所示

@Query(value="select   new in.net.rserver.domain.VerticalBarChartDomain( DATE(r.start_time), count(distinct(r.ride_id)) ) from ride r where  r.start_time >= date_sub(curdate(), interval 6 day) group by DATE(r.start_time)",nativeQuery=true)
    public List<VerticalBarChartDomain> getRidesPerDayForVBChart();

当我执行此操作时，我得到一个错误，如下所示

com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '.net.yaana.server.rserver.domain.VerticalBarChartDomain(DATE(r.start_time), coun' at line 1
