Description

@Table("product")
public class ProductMdl implements Serializable {

```
@Unique
@PrimaryKey(AssignType.AUTO_INCREMENT)
private int id;

@Column("proName")
private String proName;

@Column("proPrice")
private String proPrice;

@Column("proNum")
private String proNum;

@Column("proPhotoUrl")
private String proPhotoUrl;
```

}

@Table("tablePro")
public class TableProMdl implements Serializable {
/**
*
*/
@Unique
@PrimaryKey(AssignType.AUTO_INCREMENT)
private int id;

```
private static final long serialVersionUID = -5204190870608983058L;
@Column("tableTitle")
private String mTableTitle;

@Column("proTotal")
private String mProTotal;

@Mapping(Relation.OneToMany)
private List mProList;
```

}

tablePro这个表中 插入数据其他字段都可以插入,mProList 插入不了!

Research direction

Start by reproducing the insert with the ProductMdl and TableProMdl classes, focusing on the @Mapping(Relation.OneToMany) field mProList. Trace the ORM entry point used to persist TableProMdl and determine why the related products are not inserted; done means the other fields and the mProList relationship are both persisted correctly.
