【问题描述】：
我已经使用Room 有一段时间了，我已经使用Realm 很多年了，我不禁注意到UpdateOrInsert 的Room's 实现有点偏离。它完全删除旧记录并添加新记录而不是更新旧记录，当发生这种情况时，我所谓的“更新”字段的autoGenerate ID 丢失了，这表示我在互联网上散步并发现自己实现这个solution。我是Java 的人，所以我不得不将其转换为 Java，结果是
@SchedulerSupport(value = SchedulerSupport.IO)
@Dao
public abstract class BaseDao<T> {
@Insert(onConflict = OnConflictStrategy.IGNORE)
abstract Long insert(T item);
@Insert(onConflict = OnConflictStrategy.IGNORE)
abstract List<Long> insert(List<T> items);
@Update
abstract void update(T item);
@Update
abstract void update(List<T> items);
@Transaction
public void insertOrUpdate(T item) {
Long id = insert(item);
if (id == -1L)
update(item);
}
@Transaction
public void insertOrUpdate(List<T> objList) {
List<Long> insertResult = this.insert(objList);
List<T> updateList = new ArrayList<>();
for(int i = 0; i < insertResult.size(); i++)
if (insertResult.get(i) == -1L)
updateList.add(objList.get(i));
if (!updateList.isEmpty())
this.update(updateList);
}
}
然后我做了我的模型
@Builder
@Entity
@TypeConverters({Address.Type.class})
@Getter
@Setter
@AllArgsConstructor
@NoArgsConstructor
@EqualsAndHashCode
@ToString
public class Address {
@PrimaryKey(autoGenerate = true)
private int uuid;
@Ignore
private String placeUuid;
@ColumnInfo(name = "type")
private Type type;
@ColumnInfo(name = "title")
private String title;
@ColumnInfo(name = "icon")
private int icon;
@ColumnInfo(name = "address")
private String address;
@ColumnInfo(name = "is_address_available")
private boolean isAddressAvailable;
@ColumnInfo(name = "lat")
private double lat;
@ColumnInfo(name = "lng")
private double lng;
}
最后我把两者联系起来了
@Dao
public abstract class AddressDaoImpl extends BaseDao<Address>{
}
一切都很好，直到我尝试使用 pre-AndroidX versions of Room 依赖项编译它
implementation "android.arch.persistence.room:runtime:1.1.1"
annotationProcessor "android.arch.persistence.room:compiler:1.1.1"
implementation "android.arch.persistence.room:rxjava2:1.1.1"
编译器抱怨说我需要实现abstract List<Long> insert(List<T> items) 谷歌搜索后我终于找到了解决方案。我使用了错误的Room dependencies，我所有的其他依赖项都是AndroidX，除了这些，由于某种原因，事实证明它们没有像AndroidX 版本那样经常更新，所以我更新到新的2.2.2，它们看起来喜欢
implementation 'androidx.room:room-runtime:2.2.2'
annotationProcessor 'androidx.room:room-compiler:2.2.2'
implementation 'androidx.room:room-rxjava2:2.2.2'
迁移到这些依赖项后，错误消失了，但出现了一个新错误，现在我面临这个错误，我什至不明白如何修复它
