如何将编组的对象值(读取器)映射到spring batch中的hibernate实体对象(写入器)

import org.springframework.batch.item.ItemReader;
import org.springframework.batch.item.ItemWriter;
import org.springframework.batch.item.support.ListItemReader;
import org.springframework.batch.item.database.HibernateItemWriter;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

@Component
public class MyBatchJob {

    private final ItemReader<MyDTO> itemReader;
    private final ItemWriter<MyEntity> itemWriter;

    @Autowired
    public MyBatchJob(ItemReader<MyDTO> itemReader, ItemWriter<MyEntity> itemWriter) {
        this.itemReader = itemReader;
        this.itemWriter = itemWriter;
    }

    public void run() {
        // 从数据源中读取编组的对象值
        List<MyDTO> items = readItems();

        // 将编组的对象值映射到Hibernate实体对象
        List<MyEntity> entities = mapToEntities(items);

        // 将Hibernate实体对象写入数据库
        writeEntities(entities);
    }

    private List<MyDTO> readItems() {
        // 使用ItemReader从数据源中读取编组的对象值
        // 这里使用了一个简单的ListItemReader作为示例
        List<MyDTO> items = new ArrayList<>();
        items.add(new MyDTO("value1"));
        items.add(new MyDTO("value2"));
        return items;
    }

    private List<MyEntity> mapToEntities(List<MyDTO> items) {
        // 将编组的对象值映射到Hibernate实体对象
        List<MyEntity> entities = new ArrayList<>();
        for (MyDTO item : items) {
            MyEntity entity = new MyEntity();
            entity.setValue(item.getValue());
            entities.add(entity);
        }
        return entities;
    }

    private void writeEntities(List<MyEntity> entities) {
        // 使用HibernateItemWriter将Hibernate实体对象写入数据库
        HibernateItemWriter<MyEntity> hibernateItemWriter = new HibernateItemWriter<>();
        hibernateItemWriter.setSessionFactory(sessionFactory); // 设置Hibernate的SessionFactory
        hibernateItemWriter.write(entities);
    }
}
