" --------------------1 数据准备 --------------------
DATA:lv_text TYPE string.
DATA:lt_text TYPE TABLE OF vbak.
DATA:ls_text TYPE  vbak.

DATA:lo_serialize   TYPE REF TO cl_trex_json_serializer.
DATA:lo_deserialize TYPE REF TO cl_trex_json_deserializer.


"---------------------2 Abap list to Json string
"实例化对象
CREATE OBJECT lo_serialize
  EXPORTING
    data = lt_text.
"串行化
lo_serialize->serialize( ).
lv_text = lo_serialize->get_data( ).
WRITE:/ lv_text.

"-------------------3 Json string to Abap list

CLEAR lt_text[].
CREATE OBJECT lo_deserialize.
lo_deserialize->deserialize(
  EXPORTING
    json = lv_text
  IMPORTING
    abap = lt_text[]
   ).

LOOP AT lt_text[] INTO ls_text.
  WRITE:/ ls_text-erdat.
ENDLOOP.
