【原创】升级kotlin 1.6.x后采坑
- 我数据库使用Room, Dao层查询方法使用了suspend
@Update(onConflict = OnConflictStrategy.IGNORE)
suspend fun update(listMenu: List<TbMenu>)
然后就会报错，
error: Type of the parameter must be a class annotated with @Entity or a collection/array of it.
kotlin.coroutines.Continuation<? super kotlin.Unit> continuation);
直接去掉suspend就好了，没深入研究，我是能用就好，哈哈
- Room查询数据，如果你对象是data 修饰的，那必须全部字段返回构造中的字段否则报错
···
@Query("SELECT ID,NAME,SUBJECTID,PICTURENAME FROM abcdefg")
fun getPayWay2(): Flow<List
···
: The columns returned by the query does not have the fields [code,useState,posIseMark,serialNum] in com.baiyuas.TbPayWay even though they are annotated as non-null or primitive. Columns returned by the query: [id,name,subjectid,picturename]
public abstract kotlinx.coroutines.flow.Flow<java.util.List<com.baiyuas.TbPayWay>> getPayWay2();
所以这里必须是SELECT * FROM abcdefg 或者 自定义一个类仅包含查询的字段
另外我发现这个好像也区分大小写，如果你实体类中字段是大写，一般也会报错，框架编译返回的是小写的
