您使用的语法用于插入多个记录.这将插入4条记录，每条记录只有一个字段.

The syntax you're using is for inserting multiple records. This is going to insert 4 records, each with one field.

.values(node.getParentid())
.values(node.getName())
.values(node.getRem())
.values(node.getUipos())

但是您声明了4个字段，所以这行不通:

But you declared 4 fields, so that's not going to work:

create.insertInto(Tblcategory.TBLCATEGORY, 
  Tblcategory.PARENT_ID, Tblcategory.NAME, Tblcategory.REM, Tblcategory.UIPOS)

您可能想做的是这样:

Result<TblcategoryRecord> result = create
  .insertInto(Tblcategory.TBLCATEGORY, 
    Tblcategory.PARENT_ID, Tblcategory.NAME, Tblcategory.REM, Tblcategory.UIPOS)
  .values(node.getParentid(), node.getName(), node.getRem(), node.getUipos())
  .returning(Tblcategory.CATEGORY_ID)
  .fetch();

或者:

Result<TblcategoryRecord> result = create
  .insertInto(Tblcategory.TBLCATEGORY) 
  .set(Tblcategory.PARENT_ID, node.getParentid())
  .set(Tblcategory.NAME, node.getName())
  .set(Tblcategory.REM, node.getRem())
  .set(Tblcategory.UIPOS, node.getUipos())
  .returning(Tblcategory.CATEGORY_ID)
  .fetch();

也许，通过使用

TblcategoryRecord result =
  // [...]
  .fetchOne();
