有人可以告诉我代码中的错误吗？

标签： java spring hibernate

DAO代码如下：

public interface UserRequestResponseRepository extends CrudRepository<UserRequestResponse, Integer> {
    //public static final String FIND_QUERY = "select user.u_httpstatus ,user.u_queryparam from UserRequestResponse user";
    public static final String FIND_QUERY = 
    "select new com.abc.datacollection.entity.UserRequestResponse( user.u_queryparam , COUNT(user.u_queryparam), user.sys_created_on) from UserRequestResponse user  GROUP BY user.sys_created_on";
    @Query(value = FIND_QUERY)
    //public List<UserProjection> getAllRequestResponseRecords();
     List<UserProjection> findAllProjectedBy();

}

主要类别构造函数+导入如下（包含私有Date sys_created_on;）：

import java.sql.Date;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Transient;

public UserRequestResponse(String u_queryparam, long count, Date sys_created_on) {      //, long count
        //this.u_httpstatus = u_httpstatus;
        this.u_queryparam = u_queryparam;
        this.count=count;
        this.sys_created_on=sys_created_on;
    }

PROJECTION界面如下：

public interface UserProjection {
//  String getU_httpstatus();
    String getU_queryparam();
    long getCount();
    Date getSys_created_on();
}

堆栈跟踪如下：

在尝试将sys_created_on放入SQL查询后，错误开始出现。它在数据库中的类型是DateTime。 请帮我在这里。 TIA。 另外，还必须删除一些堆栈跟踪。

1 个答案:

答案 0 :(得分：1)

您所涉及的Date是另一种类型，应该是另一种类型：

您在UserRequestResponse类中的导入说明

import java.sql.Date;

休眠（以某种方式）希望在构造函数中使用java.util.Date。

尝试仅更改导入并再次测试代码，因此进行导入

import java.util.Date;

由于休眠状态抱怨类型不匹配，所以我认为休眠状态不能处理java.sql.Date。

该错误消息明确指出，由于参数类型不同，因此无法使用要使用的构造函数。

org.hibernate.hql.internal.ast.DetailedSemanticException:
Unable to locate appropriate constructor on class [com.abc.datacollection.entity.UserRequestResponse].
Expected arguments are: java.lang.String, long, java.util.Date

前两个类型分别为String和long，因此没有任何可能会误解任何内容。
