转换Java时Java spring启动Jpa错误。sql。日期到爪哇。时间本地日期

Question

我正在使用Java 11和Spring boot v2。3.3.释放下面是我的pom。xml。 我试图从DB函数中获取数据，它将返回两列和一行。返回的列是Date（Postgres SQL）

我有下面的模型课

import com.fasterxml.jackson.annotation.JsonFormat;

import java.time.LocalDate;


public class CachedDate {
    @JsonFormat(
            shape = JsonFormat.Shape.STRING,
            pattern = "yyyy-MM-dd",
            locale = "en_CA")
    private LocalDate businessDate;
    @JsonFormat(
            shape = JsonFormat.Shape.STRING,
            pattern = "yyyy-MM-dd",
            locale = "en_CA")
    private LocalDate previousBusinessDate;
// constructor/ getter and setter ommited
}

我有一个存储库，在那里我试图根据DB函数调用获取数据

Query query = entityManager.createNativeQuery(
        "SELECT * FROM get_function(:date)"
);
query.setParameter("date", date);
List<Object> result = (List<Object>) query.getResultList();
Iterator it = result.iterator();
CachedDate dates = new CachedDate();

while (it.hasNext()) {
    Object[] row = (Object[]) it.next();
    //dates.setBusinessDate((LocalDate) row[0]);
    //dates.setPreviousBusinessDate((LocalDate) row[1]);
     // This gives error 1


    dates.setBusinessDate(LocalDate.parse((String) row[0]));
    dates.setPreviousBusinessDate(LocalDate.parse((String) row[1]));

    // This gives error 2
}

错误1：

Caused by: java.lang.ClassCastException: class java.sql.Date cannot be cast to class java.time.LocalDate (java.sql.Date is in module java.sql of loader 'platform'; java.time.LocalDate is in module java.base of loader 'bootstrap')

错误2：

Caused by: java.lang.ClassCastException: class java.sql.Date cannot be cast to class java.lang.String (java.sql.Date is in module java.sql of loader 'platform'; java.lang.String is in module java.base of loader 'bootstrap')

这里有什么问题？ 我不能将模型类作为实体，因为它不是数据库中的对象。这正是函数返回的内容。但不确定这是否有帮助

你能帮忙吗
